Abstract
ABSTRACT
A process for producing a non-woven textile containing a bonding agent, and an adhesive on one side of the textile; in which the radiation polymerizable bonding agent is printed onto the textile from one side while the adhesive is printed on in the form of a powder by a powder-point or screen printing process from the other side. The printed textile is then subjected to irradiation from a mercury vapour lamp of which about 10 to 30% of the radiation is in the ultra-violet region for polymerizing the bonding agent.
The remainder radiation serves to heat the material so that the particles of adhesive coalesce sufficiently to maintain their geometric shape distribution in the material. The material is subsequently dried, finished and the adhesive sintered. Using the screen printing process at least 95% of the particles in the powder are less than 0.1 mm in diameter, and using the powder-point process, 95% of the particles are less than 0.2 mm diameter.

Description
~8~
This invention relates to a process for the simultaneous and conti~uous consolfdatiorl and coating of a non-woven textile, particularly for interlining or interfacing ~terials, with a bonding agent and with an adhesive maSS7 in which the bonding agent is pressed or printed on from one side simultaneously against an adhesive applied from the other side, in superimposed areas spaced from one another.
Such a process is already known from Japanese patent application laid open 9 January 1975 under number 1667/1975, inventors Katsuoshi Yamauchi et al according to which the bonding agent and the adhesive are applied while the textile is passed between a pair of engraved or screen rollers. The impressions which result on both sides are similar but this is not the intended object in using the two substances.
Bondlng agents serve primarily to fasten the fibres of a non-~oven tcxtile to one another and thus to impart strength to the fabric. This strength riseg as the number of fibres bonded together rises. It ls thus desirable that the bonding agent perletrate into the interior of the ~nbrlc being treated and that, after consolidation, the bonding agent remain dlutributed a9 evenly as possible throughout the overall cross-section.
Cross-linkable polymer substances, particularly, find practical application as bonding agents.
~ dhesives applied on the surfaces of interlining or interfacing materials serve to permit their adhesion to an adjacent fabric clothing material, to strengthen, shape and stiffen the fabric. Adhesives for this purpose are thermo-plastic, and are usually activated by the application of pressure and heat, for ex~mple, by use of a pressing iron. As distinguished therefore fro~
bonding agents, it is desirable that such adhesives not penetrate into the interior of the textile during the ironing process, but remain as far as possible undispersed at the surface to effect the mutual adhesion of the interlining to the material to be strengthened.
~; 3n ~, ~ 1 -The process of the Japanese application 1667/1~75 described above, makes it posslble to superimpose the bondin~
a8ent and th~ adheslve ove~ one ~nother on the upper and on the ~nder side of the te~tile respectlvely~ The ldentlcal printlng processe3 employed for the treatment of the upper and under sides result in equal pressing forces and thus it 1B extremely dlfflcult to effect the deslred differential penetratlon of the bonding agent ~nd the adhesive. It 16 noe possible respec~ively to ad~ust the slzes of ehe applied areas, and at grester prlntlng speeds, partlcularly when treatlng non-woven textlle3 whlch have not been previously consolida~ed, blurrlng of the p~lntlng occurs, thus yielding indetermlnate characterlstlcs for the interfacing material and its fixing surface.
Already hnown from European Pa~ent 12776 publlshed l5 December 1982, inventors Walter Fottlnger et al, i5 a process which permlts the consolldation of a non-woven textlle by prlnting wlth an ultra-violet hardenable bondlng agent, subsequently irradiated wlth a hlgh pressure mercury lamp at an op~ratlng speed o~ more thnn 50m/~ln. The questlon of application of adhesive ifl not addrcssed.
In che present dlsclosure slmultaneous and contlnuous application of a bonding agent and an adhesive on an unconsolldated, non-woven textile is described in whlch a preclse prlnted image in the form of areas wi~h superimpo6ed centre llnes is achieved, and which makes it possible to vary the speciflc quantltles applied as well as the pressing effect on both sides.
As herein descrlbed, a bondlng agent which can be cross-linked by ultra-vlolet radiaclon ls printed from the lower side of a non-woven textile agalnst a thermoplastlc adheslve prlnted onto the upper side of the textile by the powder-polnt or a screen printlng process. The bondlng agent ls then sub~ected to ultra-vlolet lrradiatlon to effect polymerlzatlon, the quantity of radlatlorl belng so selected that geometrlc stabiLlzatlon of the mass of the o~
adhesive results, and thus dispersion and blurring oE the printed image during the transfer process and the final finishing treatment in a sinterlng channel or dryer is prevented.
To effect complete cross-linking of the bonding agent distributed throughout the cross-section of the non-woven textile after printlng, ultra-violet lrradia~ion involvlng surplus energy is used. This surplus energy, which preferably accounts for more than half of the electrical energy used, cements the particles of adhesive, forming the areas raised in relief above those areas of the textile surface containing the bonding agents, to one another or to the surface of the material, so that changes in the geometrical configuration and, in particular, any separation of one part from another during transfer to the associated dryer or temperlng chamber is prevented. The radlation energy uaed ensures complete cross-linking of the bonding agent pressed into the non-woven textlle and simultaneously stabilises the areas of adhesive. A particularly favourable ratio of ultra-violet to thermal radiation Is provlded by medium and high pressure mercury ~apour lamps if these are dlrected against the ~urface of the prlnted material from both sides, without tho tl~C of Hpecial Pilters or any special coollng. An overdo~e of the radlation energy, in general~ i8 not disadvantageousi but rather favors a high grade contour definition of the resultant printed image on both sides of the fabric at the highest possible operating ~peeds. It is a distinct advantage that this image remain sharp if external factors should cause the transmission of vibration or oscillation~ to the non-woven textile. It is often extremely difflcult to suppress such movement durlng this particular stage of the process partlcularly since the material in question has a surface weight in the range uf 10 to 50 g/m2 and a working width of more than 1 m. Thus ln many instances the arrangement is extremely sensitive to displacement by air currents and draughts.
~z~
The printing processes used for applying the adhesive mass and the bonding agent can be of fundamentally different types, whereby the two substances which fulfil different functions can be applied in a coordlnated manner. It is also of importance that of the two counter-rotating printing rollers, at least one display soft-resilient characteristics, so that any differences in the thickness or elasticity of the textile belng coated are cancelled out and dlsruptlon of the printed image is avolded.
The bonding agent can be applied by using high, medium or low pressure rollers having a ~oft-resilient covering of rubber. In all three cases, it ls possible to achleve good re~ults in introducing the substan~e into the interior of the fabric. The hlgh pressure process carries with it the additional advantage of particularly high elastlcity of the surface with good resistance to fouling by fibre residues which separate from the surface of the textile.
In the high and medium pressure proce~s the quantlties of bonding agent applied can be varied continuously by ad~ustment of the pressure. Where corresponding changes are required in the use of low pressure9 a modified roll must be used. Modified roll3 ara also nec~!ssary if the size~of the areas are to be changed in an9 of the printing proce~lses described.
Such a modificatlon can, for example 9 be an increase of the dlameter, if penetration of the adheslve to the interior of the interfacing material is to be prevented when the interfacing material is to be adhered to a surface having a poor absorption capability.
The adhesive can be printed onto the material when dry, as a powder, if the powder-point process is used, or as a pasty suspended powder using a screen prlnting process~ With the powder point process, lt is not necessary subsequently to remove any carrier liquid which is required in the screen prin~ng process, ~hlch in turn means that the speciflc energy consumption is lower. The quantity of adhesive per unit of surface cannot, however, be varied ~8~
continuously in the screen printing process by simply changing the angle of rake. It is necessary thae the application roller be modified. Thus, for the production of bulk product requlrlng a constant and Ypecific predetermined application of adhe~ive the use of the powder-point process is preferred~ The screen printing proce~s is preferred for the production of snaller quantlties of interfacing material having a specified adhesive strength.
In both cases all appropriate adhesives can be used, for example, those based on polyolefins, polyurethanes, copolyamides, or copolyesters. In general the melting point should be in the range of 100C to 130C~ The particle si~e of the adhesive powder must be relatively fine to permit adequate mutual Rre-adhesion of the powder particles under the effect of the surplus thermal energy received durlng the ultra-violet polymerization of the bonding sgent.
Good results are generally achieved if the maximum diameter of 95X of the particles ln the powder-point process is less than 0.2 mm and when a dispersion or screen prir~ting process i9 used 95% have a dLameter of less than 0.1 mm.
The bonding agen~ and adhe~ive are prlnted onto the upper and lower surfaces respectlvely of the non-woven textile on a common center llne in an identical surface raster. The printing i5 configured relatively finely and the areas can be, for exampls of about 0.4 m~ to about 0.7 mm diameter with sepsration of ad~acent centre points of about 1 mm. In contrast, the fibres used for the production of an interfacing material of this type are at least 25 mm long with their relative arrangement in an irregular pattern.
It i8 to be understood that all the paramete~s are 80 chosen that distortion and damage of the material during the prlnting treatment i8 avoided.
More paxticlllarly in accord~nce with the invention there is provided, a process for the slm~ltaneous consolidation and coating of a non-woven textile material with a bonding agent and sn adhesive~ comprising the steps of:
printing a radiation polymerlæable bonding agent onto one side of said 6~3 material, while simultaneously printing a powder of thermoplastic adhesive onto the other side of said material, the bonding agent and adhesive being applied on superposed areas separated by a thickness of the material, irradiating said material ~o polymeri~e the bonding agent and stabilize the adhesive ~ith radiation of whose total energy about 10% to about 30%
comprises ultra-violet radiation, the total dose of irradiation applied to said material being chosen for polymerizing said bonding agent and simultaneously fusing said adhesive to stabilise it geometrically in the material. The adhesive may be subsequently sintered in the textile. The adhesive may be applied by a screen printing or powder-point process in which the particles comprising the adhesive are 95~ less than 0.1 or 0.2 mm respectively. The bonding agent and adhesive may be applied in a regular or irregular surface raster pattern and the areas of bonding agent may be greater and overlap their respective adhesive areas.

a8ent and th~ adheslve ove~ one ~nother on the upper and on the ~nder side of the te~tile respectlvely~ The ldentlcal printlng processe3 employed for the treatment of the upper and under sides result in equal pressing forces and thus it 1B extremely dlfflcult to effect the deslred differential penetratlon of the bonding agent ~nd the adhesive. It 16 noe possible respec~ively to ad~ust the slzes of ehe applied areas, and at grester prlntlng speeds, partlcularly when treatlng non-woven textlle3 whlch have not been previously consolida~ed, blurrlng of the p~lntlng occurs, thus yielding indetermlnate characterlstlcs for the interfacing material and its fixing surface.
Already hnown from European Pa~ent 12776 publlshed l5 December 1982, inventors Walter Fottlnger et al, i5 a process which permlts the consolldation of a non-woven textlle by prlnting wlth an ultra-violet hardenable bondlng agent, subsequently irradiated wlth a hlgh pressure mercury lamp at an op~ratlng speed o~ more thnn 50m/~ln. The questlon of application of adhesive ifl not addrcssed.
In che present dlsclosure slmultaneous and contlnuous application of a bonding agent and an adhesive on an unconsolldated, non-woven textile is described in whlch a preclse prlnted image in the form of areas wi~h superimpo6ed centre llnes is achieved, and which makes it possible to vary the speciflc quantltles applied as well as the pressing effect on both sides.
As herein descrlbed, a bondlng agent which can be cross-linked by ultra-vlolet radiaclon ls printed from the lower side of a non-woven textile agalnst a thermoplastlc adheslve prlnted onto the upper side of the textile by the powder-polnt or a screen printlng process. The bondlng agent ls then sub~ected to ultra-vlolet lrradiatlon to effect polymerlzatlon, the quantity of radlatlorl belng so selected that geometrlc stabiLlzatlon of the mass of the o~
adhesive results, and thus dispersion and blurring oE the printed image during the transfer process and the final finishing treatment in a sinterlng channel or dryer is prevented.
To effect complete cross-linking of the bonding agent distributed throughout the cross-section of the non-woven textile after printlng, ultra-violet lrradia~ion involvlng surplus energy is used. This surplus energy, which preferably accounts for more than half of the electrical energy used, cements the particles of adhesive, forming the areas raised in relief above those areas of the textile surface containing the bonding agents, to one another or to the surface of the material, so that changes in the geometrical configuration and, in particular, any separation of one part from another during transfer to the associated dryer or temperlng chamber is prevented. The radlation energy uaed ensures complete cross-linking of the bonding agent pressed into the non-woven textlle and simultaneously stabilises the areas of adhesive. A particularly favourable ratio of ultra-violet to thermal radiation Is provlded by medium and high pressure mercury ~apour lamps if these are dlrected against the ~urface of the prlnted material from both sides, without tho tl~C of Hpecial Pilters or any special coollng. An overdo~e of the radlation energy, in general~ i8 not disadvantageousi but rather favors a high grade contour definition of the resultant printed image on both sides of the fabric at the highest possible operating ~peeds. It is a distinct advantage that this image remain sharp if external factors should cause the transmission of vibration or oscillation~ to the non-woven textile. It is often extremely difflcult to suppress such movement durlng this particular stage of the process partlcularly since the material in question has a surface weight in the range uf 10 to 50 g/m2 and a working width of more than 1 m. Thus ln many instances the arrangement is extremely sensitive to displacement by air currents and draughts.
~z~
The printing processes used for applying the adhesive mass and the bonding agent can be of fundamentally different types, whereby the two substances which fulfil different functions can be applied in a coordlnated manner. It is also of importance that of the two counter-rotating printing rollers, at least one display soft-resilient characteristics, so that any differences in the thickness or elasticity of the textile belng coated are cancelled out and dlsruptlon of the printed image is avolded.
The bonding agent can be applied by using high, medium or low pressure rollers having a ~oft-resilient covering of rubber. In all three cases, it ls possible to achleve good re~ults in introducing the substan~e into the interior of the fabric. The hlgh pressure process carries with it the additional advantage of particularly high elastlcity of the surface with good resistance to fouling by fibre residues which separate from the surface of the textile.
In the high and medium pressure proce~s the quantlties of bonding agent applied can be varied continuously by ad~ustment of the pressure. Where corresponding changes are required in the use of low pressure9 a modified roll must be used. Modified roll3 ara also nec~!ssary if the size~of the areas are to be changed in an9 of the printing proce~lses described.
Such a modificatlon can, for example 9 be an increase of the dlameter, if penetration of the adheslve to the interior of the interfacing material is to be prevented when the interfacing material is to be adhered to a surface having a poor absorption capability.
The adhesive can be printed onto the material when dry, as a powder, if the powder-point process is used, or as a pasty suspended powder using a screen prlnting process~ With the powder point process, lt is not necessary subsequently to remove any carrier liquid which is required in the screen prin~ng process, ~hlch in turn means that the speciflc energy consumption is lower. The quantity of adhesive per unit of surface cannot, however, be varied ~8~
continuously in the screen printing process by simply changing the angle of rake. It is necessary thae the application roller be modified. Thus, for the production of bulk product requlrlng a constant and Ypecific predetermined application of adhe~ive the use of the powder-point process is preferred~ The screen printing proce~s is preferred for the production of snaller quantlties of interfacing material having a specified adhesive strength.
In both cases all appropriate adhesives can be used, for example, those based on polyolefins, polyurethanes, copolyamides, or copolyesters. In general the melting point should be in the range of 100C to 130C~ The particle si~e of the adhesive powder must be relatively fine to permit adequate mutual Rre-adhesion of the powder particles under the effect of the surplus thermal energy received durlng the ultra-violet polymerization of the bonding sgent.
Good results are generally achieved if the maximum diameter of 95X of the particles ln the powder-point process is less than 0.2 mm and when a dispersion or screen prir~ting process i9 used 95% have a dLameter of less than 0.1 mm.
The bonding agen~ and adhe~ive are prlnted onto the upper and lower surfaces respectlvely of the non-woven textile on a common center llne in an identical surface raster. The printing i5 configured relatively finely and the areas can be, for exampls of about 0.4 m~ to about 0.7 mm diameter with sepsration of ad~acent centre points of about 1 mm. In contrast, the fibres used for the production of an interfacing material of this type are at least 25 mm long with their relative arrangement in an irregular pattern.
It i8 to be understood that all the paramete~s are 80 chosen that distortion and damage of the material during the prlnting treatment i8 avoided.
More paxticlllarly in accord~nce with the invention there is provided, a process for the slm~ltaneous consolidation and coating of a non-woven textile material with a bonding agent and sn adhesive~ comprising the steps of:
printing a radiation polymerlæable bonding agent onto one side of said 6~3 material, while simultaneously printing a powder of thermoplastic adhesive onto the other side of said material, the bonding agent and adhesive being applied on superposed areas separated by a thickness of the material, irradiating said material ~o polymeri~e the bonding agent and stabilize the adhesive ~ith radiation of whose total energy about 10% to about 30%
comprises ultra-violet radiation, the total dose of irradiation applied to said material being chosen for polymerizing said bonding agent and simultaneously fusing said adhesive to stabilise it geometrically in the material. The adhesive may be subsequently sintered in the textile. The adhesive may be applied by a screen printing or powder-point process in which the particles comprising the adhesive are 95~ less than 0.1 or 0.2 mm respectively. The bonding agent and adhesive may be applied in a regular or irregular surface raster pattern and the areas of bonding agent may be greater and overlap their respective adhesive areas.
Specific embodiments of the invention will now be described having reference to the accompanying drawings in which:
~ igure 1 i8 a diagrammatic side view oi- a screen printing apparatus for a non-woven textile and, Figure 2 is a diagrammatic side view of a pressure, powder-point prlnting apparatus for a non-woven textile.
Example 1 Using a plurality of longitudinally orlented carding devices, a non-woven textile of 100~ polyester fibres of 1.7 dtex/40 mm a~d a specific weight of 25 g/m2 was produced at a speed of 60 m/min. ~he fabric was passed between a pair of counter rollers heated to 150C and was consolidated at a linear pressure of 15 kp/cm. Immediately afterwards the fabric was passed through an imprinting device, as illustrated in Fig. 1. The upper roll is a screen printing template or stencil 1 with a 25 mesh raster. The hole diameter is at 0.4S mm and the template ~hicknes~ 0.19 ~m. A spreader 3 i8 mounted in the screen prin~ing cylinder 80 that it i9 ad~ustable a~ an incllned angle to the vertical.
An aqueous adhesive paste 2 is printed onto the fabric using the screen printing cylinder 1. The adhesive paste 2 contains 40% by weight of a ~ernary copolyamide powder of ~a~i-nlactam, caprolactam, and AH-Salt (based on adlpinic acid-hexamethylenediamine3 having a ~aximum particle diameter of 10 to 80 u and a melting point of 115C; adjusted to a visc05ity of 15,000 m Pas ~ec by the addition of an acrylate thickener with ammonia. The wet application on the textile 4 18 at 30 gtm29 which becomes 12 g/m2 after drying.
The lo~er roll 5 is a rubber high-pres~ure roll, the rubber being resi~tant to organic liquids and with a Shore-~ hardness o~ 65~ The printing pattern i9 identlcal to that of the screen printing cylinder, whereas the dinmeter of the printlng points i~ 0.8 mm. The engraving is 0.4 mm deep.
A bonding agent mlxture described below was transferred from a pre-polymer bath 6 preheated to 60C via a rubber pickup roll 7 and a chromed transfer roll a, al90 heated to 60C and having a 60 mesh engraving, ~o the rubber high pressure roll 5. The speed of the pickuy roll 8 wa~ adJusted R0 that printed quantity from the high-pressure roll onto the non-woven textile was at
2.5 glm2~
The ewo rolls were so ad~u~ted that the centers of the areas b~ing imprinted were ouperposed one above the other.
The bondlng agen~ was composed as ~ollows:
Epoxy acrylate70 parts Oligotriacrylate 30 ' Benzophenone 2 Benzyldimethylketal N-methyl-diethanolamine3 Opt~cal brightener 0.03 "
32~
After leaving the printing machinery the textile is moved by means of a metal conveyor belt throllgh a light lock and into a light cabinet where it was passed between an upper and a lower row of high-pressure mercury lamps having a power output of 200 watt/cm. The bonding agent hardened instantaneously; the fabric left the cabinet through a second light lock and was then moved through a 15 m length tensioning fra~e in which the adhesive was dried at an ambient air temperature of 115C and then finally sintered.
Fabric from the tensioning frame was edge cut on both sides with the help of cutters and then divided in the center. This made it possible to roll off two bands of interlining fabric 90 cm wide ready for merchandising.
The interlining materlal so obtained was very soft and had good drape. It displayed good resistance to chemical cleaning and showed excellent laundering propertie~. It could be processed very easily with conventional interlining working apparatlls.
~xample 2 A cross laid-up non-woven textile was placed on a lattice work table using croas~arms and ~everal carding devices oriented transversely to the work flow of thc machinery. The welght per unit area of the band Oe non-woven textile wa~ 27 g/m2 and was 195 cm wide. The fibre mixture was as follows:
Tlghtly crlmped polyamide fibre, 1.7 dtex/cu~ length 40 mm 40 parts Tightly crimped pDlyamide fibre, 3.3 dtex/cut length 52 mm 30 parts Polyester Eibre 1.6 dtex/cut length 40 mm 30 parts As in example 19 the non-woven textile was passed through a pair of heated roll8. The surface te~perature of the rolls was 190C, the linear pressure 30 kp/cm, and the clrcumferential speed 25 mtmin.
Immediately after leaving through the heated rolls, the materiAl was passed through a printing device as shown in Fig. 2.

The lower three rolls including the pre-polymer bath are ldentical to those in Example l as is the compoæition of the pre-polymer mixture, its temperature, and the heating data for the transfer roll.
The upper roll 9 is conflgured as a powder-polnt application roll. The printing pattern is conflgured as a 25 mesh-point series and its pattern absolutely identical to that of the 25 mesh raster of the hlgh-pressure rubber roll 5 situated below, (whose circular printing points are of a diameter of 0.8 mm). The depth of the engravings of the matt`of roll 9 waæ 0.25 mm and their dlameter 0.40 mmO
The powder roll was heated to a surface temperature of 68C. It was then coated at l5 g/m2 wlth a ternary copolyamide powder lO havi~g a maxlmum particle diameter of l to 200 u and a melting range of 120C to 130C.
Simultaneou~ly, and at the æame places on the strip, 3 g/m2 of the prepolymer bonding mixture hardenable under ultra-vlolet radlatlon as descrlbed ln ~xample l were applled from below by the rubber high-pressure roll 5. After leavlng the printing device the te~tile passed into the light cabinet described ln ~xample l. This reaulted in hardening of the bondlng agent and geometrlc ~t~bill~ation of the adhesive yatches. The adheælve partlcle~ already then mutually adhering were finally sintered in a subsequent infrared field (radlated temperature of 400C). After passing through a cooling roll the strip of material waæ cut into two bands each 90 cm wide and rolled up as in Example l.
Thi~ resulted in an especially soft multi-directional in~erlining fabric having a high volume, good drape, and displaylng excellent resistance to laundering and cleaning.

In addition to the previously described regular surface raster, these areas can be applied in any desired pat~ern, for exa~ple, in a scatter raster which is oriented statistically and which is frequently preferred. A round configuration~ or any other desired shape is possible.
The ewo rolls were so ad~u~ted that the centers of the areas b~ing imprinted were ouperposed one above the other.
