Description

"EQUIPMENT FOR APPLICATION OF PIGMENT DYES, DYES AND OTHER CHEMICAL PRODUCTS IN TEXTILE MATERIALS AND PROCESS FOR APPLICATION OF PIGMENT DYES, DYES AND OTHER CHEMICAL PRODUCTS"

The present patent application is a device specially developed to allow the application of pigment dyes, dyes and other chemicals in textile materials by continuous spraying by centrifugation of such substances during the passage of the textile material inside said equipment. The present patent application also addresses the process by which the application of pigment dyes, dyes and other chemicals in textile materials is produced, which process is carried out within the above mentioned equipment.

For the purposes of definition only, dyeing consists of fixing the dye on a fiber so that the dye depends on the quality of the textile fiber and the chemical composition of the dye. Within the scope of the present patent application, dyeing occurs by centrifugal dye spraying so that the textile material is passed through the spray field thus uniformly receiving the desired charge of that dye.

More broadly, dyeing is a chemical process of modifying textile fiber by applying dyes (dyes) through a solution or dispersion, which process varies from material to material, as compared to each fiber type. textile there are specific dyes.

In the dyeing process there is a physicochemical modification of the material so that the reflected light causes a color perception, aiming at the application to be made so that the color is relatively solid to light and wet treatments.

The state of the art contemplates a reality whereby dyeing of flat fabrics is predominantly done by "dyeing foulards".

"Dyeing foulards" have a technology permeated with limitations, which may include: a) speed limitation; b) "edge-center-edge" nuance problems; c) restriction of lots of matches; d) waste of baths; and e) high energy consumption in the drying process.

This state of the art is also embodied by another form of dyeing whereby the dye is fed to a centrifugal device which promotes its spraying. There are a number of patents that ineffectively address liquid centrifuge spray systems on moving textile structures.

Many attempts have been made to produce dye baths using the centrifugal force of rotors or discs, and such technique presents a number of technical challenges, among which is the uniform distribution of small amounts in the width of the textile material and especially the formation of unwanted streaks or stripes along the fabric.

For this type of technique the droplet size of the spray material is of paramount importance as the area of the spray material absorbs aerosols. The textile material will absorb to its own weight and the purpose is to apply the dyebath at a proportion of 30% or less of the weight of the textile material.

Therefore, the method for achieving the desired application must overcome the surface tension of the liquid by reducing the size of the aerosol and achieving a wider and more uniform distribution of the liquid across the width of the textile material without causing streaks or streaks.

It should also be borne in mind that in the textile industry it is desired to apply pigments, dyes or chemicals to the surface of the textile material (flat fabrics, knits, rugs, etc.) with the aim of manufacturing small production batches, reducing product consumption. reduce drying costs and energy consumption in general, and such objectives are not yet fully achieved.

The state of the art regarding the use of centrifugal sprinkler based solutions contemplates a series of patents, among which the following documents are commented:

In the patent filed by Plotz, US 3,903,715 discloses an arrangement of discs, which are positioned horizontally on a moving mat, the dye bath aerosols being sprayed horizontally through a rotating disc, the aerosols being deposited. through gravity on the moving textile material.

In the patent filed by Hess, US 6,746,536, the disks rotate about their axes vertically and spray water or chemicals by centrifugal force on a moving textile material. The textile material is sprayed on one side or both sides at the same time. The discs are rotated through a belt in one direction, spraying water or chemical; This feature disables this system for applying dye baths due to the formation of streaks or stripes, which qualifies the dyed material as non-conforming.

Another variant is Norton US 4,338,876, in which the distributing discs rotate on their own vertical axes. The discs are mounted adjacent to a support and spray the aerosols onto the moving textile by centrifugal force. The discs are individually rotated by their own motor in one direction, spraying water or chemical, this feature disables this system for dyeing baths, due to the formation of stripes or stripes, which qualifies the dyed material as non-conforming.

The patent filed by Bryant, US 4,803,746, discloses an arrangement of discs, which are positioned horizontally on a moving mat. This system employs irregularly contoured discs to apply random dyeing patterns, ie in non-uniform form.

The described deficiencies of these arrangements (distributions) for dyeing baths in textile materials and the inability of said systems to achieve uniform application, avoiding the formation of bands or overlaps that characterize these patents. Typically the textile material to be dyed has widths of over 2,000 mm, and several rotating discs are required to spray the full width dyeing or chemical spray. Said discs are positioned such that adjacent application areas overlap, not completely controlled, forming undesirable streaks or stripes to product quality.

Other patents filed on centrifugal sprinkling are: DE 215096, October 1909; DE 222192, May 1910; US 2894485, July 1959; CH 534051, April 1973; DE 2058667, May 1972; US 3749313, July 1973-Weitmann; DE 2207102, August 1973; GB 1439963, June 1976; US 4006858, February 1977 - Farmery; No. 4,338,376, July 1982 - Norton; US 4,366,849, January 1983 - Farmery.

The above documents have not been successful in solving all problems and / or limitations of currently known equipment / processes, which is why the applicant has sought to develop a design solution which is described and illustrated in this patent application, which proposes a new process and machine for uniform application of the dyeing bath in textile materials such as flat fabrics, knitwear, rugs and nonwovens without the formation of stripes or stripes, in which case the process is monitored in real time measuring the application of the dye bath to the full width of the textile material by means of microwave technology equipment. When the dyeing quality is "non-compliant" in the uniformity of application, the system emits a visual / acoustic signal and the process is interrupted.

With respect to the equipment proposed herein, the present patent application is composed of the following subsystems: a) chamber for applying dye to textile material; b) operational cabinet, in which the bath tank with its fundamental components and electrical cabinet are installed having the HMI integrated with PLC, which contains the command software with the cascading algorithms for process parameter control.

With the equipment proposed in this patent application batches can be processed with smaller or lesser production, as well as batches with larger productions with larger footage, without waste of dyeing bath, avoiding longer times for the preparation of the machine for a New batch of dyeing.

The object of this patent application will be described in detail with reference to the following drawings, in which: Figure 1 illustrates an overview of the proposed equipment, which by way of non-limiting example is integrated in a finishing branch, which condition is as follows. which is one of the possible applications, as the present machine may also be integrated into a thermosol line or other textile process configuration;

The present patent application proposes, as one of its aspects, the equipment for the application of pigment dyes, dyes and other chemicals in textile materials, which is generally indicated by the numerical reference 1, said equipment 1, such as As can be seen from the observation of FIG. 1, it can be incorporated into a branch 2 and operates in conjunction with a frame 3 which serves as a mounting and mounting location for device 4, which performs dyeing quality sensing, device 4 which which operates on microwave technology, as will be better explained.

The equipment 1 proposed herein comprises a chamber 5, within which are mounted conveyor rollers generally indicated by the numeral reference 6, through which the textile material T to be dyed is neatly passed. The chamber 5 still houses inside it a pair of rotor holder structures 7.

The apparatus 1 treated herein operates according to a method, wherein the dyeing bath is applied simultaneously once or several times, alternately, at a given time interval, on both sides of the moving textile material T, thereby contributing to for better penetration of the dyeing bath into the processed T textile material.

The heatable chamber 5 is open at its rear, which contains an access door. Within said chamber 5 are mounted the aforementioned (motorized) conveyor rollers 6 which are rotating in sync, specifically indicated by references 6A, 6B, 6C, 6D, 6E, 6F, 6G and 6H, where roller 6A represents the first roller contacting textile T, while roller 6H represents the last roller to contact textile T thus forming (along with the other rollers) the path of textile material Τ which can be seen in figures 2 and 3.

At the entrance to the chamber 5 there is arranged the conveyor roller 6A supporting the textile T which goes to the roller 6B and then, already in the vertical position, the textile material T moving upwards between the rollers 6B and 6C receives the right side of the textile T the first application of the first rotor holder 7A; the space between the rollers 6C and 6D is intended to bypass the first rotor holder 7A, then, right downwards the right side of the textile T receives the second application of the same first rotor holder 7A and simultaneously, Also receive the left side of the textile T the first application of the second rotor holder 7B. The distance between the rollers 6E and 6F allows to contour the second rotor holder 7B and when traveling between the rollers 6F and 6G the left side of the textile T receives the second application of the second rotor holder 7B, thus the textile T receives two applications on its right side by the first rotor holder 7A and two other applications on its left side by the second rotor holder 7B.

Depending on the arrangement of the conveyor rollers 6 (6A to 6H), there is a residence time of the textile material T within the dyeing chamber 5, which is the time required to travel the distance between the rollers 6A and 6H, whereby said roller 6H is in the chamber 5 outlet where the textile material T proceeds to the next production process.

As can be seen from the observation of figure 2A, the dyeing equipment 1 proposed here, in addition to the main model that has eight units of the conveyor roller 6, can also have a constructive variant, which differs from the main model in that different arrangement with respect to its conveyor rollers 6 using a number of six of these components (from 6A to 6F), without prejudice to the efficiency of the equipment, as the textile material T passes through the rotor holders 7A and 7B identically what happens in the equipment of the main model depicted in the other figures.

The version proposed in Figure 2A simply aims to reduce the number of conveyor rollers 6 used in the present dyeing equipment 1, as such rollers are usually high cost components.

Below the rotor holders 7A and 7B are installed the respective collecting rails 8 which through pipes 9 are interconnected with the intermediate tank 10.

In operation, the textile material T to be sprayed is moved through the chamber 5, while the dyeing bath 11 containing the dyes, resins or finishing agents is pumped by the pump 15A through the filter 14A to the nozzles 12 which feed the spinning discs 13 via the flow sensor (30) (closed loop electromagnetic).

From the intermediate tank 10, the dye bath 11 is filtered by passing through the return filter 14 and through a double diaphragm pneumatic pump 15, the liquid 11 is sent to the supply tank 16.

The absolute amount of the spray dyeing bath 11 is measured by the flow sensor (30), and automatically adjusted according to the speed of the equipment 1 proposed herein.

The centrifuge, as shown in Figure 2, consists of two rotor holders or racks, referred to as the first and second rotor holders 7A and 7B, on which numerous rotors 17 are mounted, each having a respective disc. 13 of a given diameter at a constant "D" distance between the axes 18. The rotating discs 13 fitted to a bearing 19 rotate parallel to its axes 18, and the adjacent adjacent rotating disc 13 sprays pigment dyeing bath 11. or dye in centrifugal and uniform form opposite the preceding spinning disk 13 on the surface of the moving textile T.

The rotor holders 7A and 7B as shown in Figure 2 are identical and are arranged on a support of the rotors 20 and are distributed in the width of the chamber 5; all rotors 17 are driven by a single toothed belt 21 to prevent slippage between belt 21 and pulley 22 of rotor 17 this belt is driven by a single electric motor 23 and is protected to prevent contact with the bath aerosols. dyeing.

The rotor holder 20 is supported on structural members 24, which in turn are attached to the walls 25 of chamber 5.

Rotor holders 7A and 7B as shown in Figure 5 are retractable and can be removed from chamber 5 for maintenance or rotor change 17 without altering or de-routing the textile material Τ. Removal of rotor holders 7A and 7B is accomplished without the use of tools, substantially reducing downtime.

Each rotor 17 comprises a spinning disc 13 coupled to an axis 18, which axis 18 is mounted on a bearing 19 with two ball bearings 26 which are protected by a cap 27 to prevent contact with the dye bath aerosols and to prevent belt 21 contact with the applied liquid, pulley 22 and belt 21 are isolated below the rotor support 20.

The surface of each rotating disc 13 of the rotor 17, on which the liquid 11 is deposited, can be textured to break the drops into aerosols A, thereby reducing their size.

The dye bath 11 at the entrance of the rotor holders 7A and 7B passes a flow sensor (30) and feeds the rotating discs 13 of the rotors 17 which spray the dye bath 11 onto the moving textile T.

The feeding of the spinning discs 13 with the dyeing bath 11 is carried out via a distributing support 28 positioned above and centered on the rotors 17. The dyeing bath 11 is fed into the spinning discs 13 of the rotors 17 through respective nozzles 12 These extremely precision bore components are responsible, together with the respective rotary disks 13 of the rotors 17, for spraying the dye bath 11 on the moving textile T. The spinning discs 13 through centrifugal force expel liquid 11 against textile T with sufficient force to break aerosol droplets. The application rate of liquid 11 to textile T is measured and controlled by the flow sensor (30), taking into account the speed of equipment 1, ie the faster the textile T moves, the higher the rate. 15A pump power supply and vice versa. The volume of the dyeing bath 11 is carried to the spinning disc 13 and approximately 20% of this volume is sprayed onto the textile T and 80% is collected by the collecting rails 8 installed below the rotor bearings 19. The liquid collected by the collecting rails 8 returns to intermediate tank 10.

In special applications there is the possibility, with the equipment 1 treated here, in one pass to apply / spray two different chemical media, for example: a dye (with the first rotor holder 7A) and a binder (with the second rotor holder 7B), simultaneously and lagged in a moving T textile material.

In the operating cabinet are installed: the tank with all components such as filters, mixer (not shown), viscometer (not shown) and submersible pump 15A. The present equipment 1 also has an electrical cabinet 29, which includes a control unit - HMI with integrated PLC, which executes the process command. When starting on equipment 1, the rotor disks 13 of the rotors 17 rotate and a rotation sensor (not shown) signals the value of revolutions per minute (RPM).

The control unit through the cascade algorithms integrates the information sent by the sensors, such as: rotor speed (RPM); pump frequency 15A (Hz); spray amount (ml) / (m / min); machine speed (m / min); .unit of impregnated textile material T (g / H20 / m2); temperature (° C) inside chamber 5 with the preset dyeing parameters such as: the diameter of the rotor discs (mm); the diameter of aerosols (μ); percentage of pigment or dye application as a function of viscosity; application distance, i.e. application spray (g / m2); viscosity of the dyeing bath 11 (cps), acting: on the rotation of the pump 15A, i.e., the amount to be fed to the rotor disc 13 of the rotor 17; visual / acoustic alarm sensors.

In the dyeing process it is essential to apply the pigment or dye 11 evenly, otherwise the quality of the dyed textile material is not approved and a reprocessing with all the drawbacks and costs involved is required.

Measurement and monitoring of the homogeneity of dyeing bath application 11 over the full width of textile T is carried out by means of a dual-head microwave dyeing measuring instrument. The heads are mounted in a rack which moves horizontally across the full width of the moving T textile material. The measuring range can be chosen: from 0 - 25 to O-5,000 (g / H20 / m2).

Figure 9 specifically shines a particular feature of the equipment 1 in question, namely the provision thereof with a device 4 which checks the amount of dye bath 11 that is applied by the rotors 17. The device 4 is configured, preferably by a nAF 110 "sensor, which operates on the principle of microwave emission and which has transverse motion with respect to the direction of travel of the textile material T.

The device 4 has the function of measuring and monitoring the application of the dyeing to the full width of the textile material T, as shown in figure 9 and in particular the enlarged detail of said figure, where it can be seen schematically, both the device 4 their heads, emitter 4A and receiver 4B, as well as the textile T which passes between the two mentioned heads.

Device 4, by measuring and monitoring the amount of T (dyebath) 11 that is applied against T, allows possible variations, when identified, to be specifically related to one or more rotors 17, thus facilitating equipment repair 1.

The process for applying pigment dyes, dyes and other chemicals in textile materials T which also characterizes the present patent application relates to the manner in which the present equipment 1 operates, i.e. the possibility of producing the lagged application of the dyeing bath 11 on both sides of the textile material T, which application is carried out by turning the spinning discs 13 of the rotors 17.

Moreover, the process discussed herein is substantially more efficient than conventional processes in that each rotor assembly 17 drives its respective spinning discs 13 in mutually opposite directions, as can best be appreciated by looking at Figure 8, in which it can be seen that the flows of aerosols A produced by the rotors 17 do not follow the same direction.

In other words the rotors 17 of each of the rotor holder assemblies 7A and 7B produce their aerosol flows A in a different direction from the flow direction produced by the immediately adjacent rotor 17.

When viewed from a higher angle, as shown in Figure 8, it may be noted that the rotor holder assembly (7A or 7B) has its spinning discs 13 rotating in opposite directions, where the first spinning disc 13 (left to right). right) rotates clockwise, while the second spinning disc 13 (in the same direction from right to left) rotates counterclockwise, with these mutually opposite turns occurring in the other spinning discs 13.

Aerosol flows A produced in opposite directions are responsible for eliminating the inconvenience that undesirable strips are usually created along the textile material T which is dyed in conventional equipment.

On the other hand, the drive of the rotors 17 in different directions is ingeniously and simply obtained by adopting the arrangement of a single belt 21 passing through the pulleys so that the direction in which coupling of said belt 21 occurs with the pulleys 22 as best understood by viewing the enlarged detail taken from figure 8.

The use of a single belt 21 allows all rotors 17 to rotate in different directions but fully synchronized since said belt 21 is coupled to a single electric motor 23.

As can be seen, for example, from Fig. 1, the textile material T is pulled through the motorized cylinders 6 (both in the version of equipment 1 which has eight, and also in the alternative version of the same which is provided with six units thereof). component) disposed within the treatment chamber 5, which avoids any tension of the processed textile substrate T. In the case of dyeing of meshes, and with a view to also avoiding tensions to the textile substrate, internal transport in the dyeing chamber 5 may be carried out by conveyor chain (not shown).
