A transmission method is already known with which on artificial or synthetic textiles »such as those made of cellulose acetate, super polyamide, polyester or acrylic copolymer, Can carry out dyeings and prints. This method consists in that one on the carrier, the is used for transfer, applies a dye which, in the vapor state, has a high affinity for the fibers used and that the carrier provided with the dye is brought into the vicinity of the textiles to be dyed or printed, bringing the fibers to a temperature sufficient to cause the subliming dye to vaporize into the textile fibers penetration.

The dyes used according to this known method are essentially the so-called dispersing dyes or plastosoluble dyes.

With the above-mentioned known method, textiles based on cotton, cellulose fibers, Wool as well as other animal or vegetable fibers Do not print or dye the origin.

The invention relates to a new method with which aioh by transferring the printing or dyeing of textiles made of any fibers can be carried out, the pich according to known Let process color

909832/0913 ' ⁵ *

The inventive method is used for dyeing or printing of textiles with dyes of the usual type, which are known to be used in accordance with conventional methods, except the transmission method, can color or print

In other words, the invention relates to a transmission method, with which textiles can be dyed or printed in a new way by means of dyes, which is customary can be used to dye the same textiles.

The invention is a new method for decorating, dyeing and printing objects, thereby is characterized in that at least one dye or a dye preparation is applied to a support which for dyeing the textile to be dyed is suitable that one of the so provided support and the to be decorated, to be dyed or the object to be printed is placed next to one another and that pressure is applied to the object and the carrier at the same time, Temperature increase and humidification can act from Addition of a liquid possibly brought into the vapor state arises.

The method according to the invention is suitable for all types of textiles, especially for mats or fleece made of un-

909832/0913 '- ♦ -

connected fibers, for textile yarns or threads, for woven, knitted or lace fabrics, for sponge fabrics or in sheets or already formed or even for already finished garments.

The textiles can be made of any type of natural, artificial or synthetic fibers, optionally mixed with one another.

They can also be non-textiles, e.g. Paper, wood, leather, rubber, absorbent natural or synthetic resins or metals such as anodized aluminum.

The dyes used for dyeing or printing according to the invention can be those customarily used for dyeing fibers dyes used in the construction of the textile penetration. So you can use metal complex dyes for dyeing or printing silk, wool, polyamides, polyacrylonitriles, Select polyurethanes or mixtures of these different fibers.

You can also use kaiionische dyes according to the invention Treatment of wool, polyacrylonitriles or their mixture use.

90983 270913

Mixtures of acidic dyes can also be used, for example and plastosoluble dyes (sublimable or not sublimable) for the inventive treatment of mixtures of keratinic fibers (e.g. solid) and fibers made of polyesters, Polyamides »polyacrylonitriles ^ cellulose acetate or cellulose triacetate fibers or vinyl fibers and fibers use made of polyurethane and polyurethane glycol

Mixtures of reactive dyes and plastosoluble dyes can be used in a similar manner Dyes for dyeing mixtures of cellulose fibers and use synthetic fibers.

According to the invention, one can use as a carrier for transferring the dyes use different types of material, such as fabric, paper, nonwoven fiber bandages, sheet metal or Wire netting, plastic sheeting and glass.

The carrier can be vapor-permeable, so that you can carry out dor transfer a steam circulation through the Carrier and the textile to be treated can achieve

The carrier can also be impermeable to vapor; in this In the case of the process according to the invention, steam or liquid is only used through the textile is vapor permeable

909832/0913

According to the invention, it is preferred to use the carrier from a Manufacture material to which the dyes used have a weak affinity, yet this condition is by no means absolutely necessary, and one can, for example, use paper as a dye carrier to make cotton dyeing or printing, the fiber of which is also made of cellulose like that of paper. A carrier with a lower affinity for the dye is preferably used, because you get a slightly higher performance, but can this consideration can be outweighed by the fact that there is always an interest in choosing a transmission medium that is as cheap as possible.

In certain cases one can also use a siliconized carrier use, for which the dyes have only a very weak affinity, so that one in the transfer of certain Dyes can achieve a very high performance »

On the same support can be dyes of colors apply verschiedenerlei, the colors may be either intimately mixed or distributed ₉ to form patterns that are transferred onto DIE> f extüieifc. . . _; ;

liquid or in the form of emulsions or suspensions. To the application d§r containing the dyes To make preparations easier, thickeners can be incorporated into them to reduce the viscosity of the preparation to regulate according to the requirements.

According to the invention, the preparation containing the dyes is also mixed with ingredients that are necessary for dye fixation on the textile fiber are necessary, as also, if necessary, with the classic fabrics for improvement the consonance or the fixing speed of the dyes or with the substances that lower the temperature serve in which the staining is to be carried out.

The amount of dye to be applied to the support depends on the surface structure of the textile to be treated, the importance of the penetration desired for the dye into the fiber, on the desired intensity of the dyeing and, if necessary, on the number of textiles, that you want to dye or print with the same carrier.

The inventive method can be applied to any Machine that can be used at the same time

Exert pressure on the support and the textile to be treated, increase the temperature of the support and the textile and

909832/0913 " ⁸ "

can create a humid environment ₉ which is necessary for dye transfer »

For example, the carrier can be used together with the one to be colored od @ r ssu printing textile between the two parts a press (this can have two plates or rotating drums or the well-known combination of mushroom and rollers), one of these parts being heated to the appropriate temperature, while the other part is optionally heated is provided with holes and, if necessary, allows the introduction of vapors or a liquid

According to the invention, the temperature at which the dye transfer is carried out depends on the nature of the dyes and is generally from 80 to 300 ⁰ *

The steam is preferably water vapor, but the process can can also be carried out using steam, organic solvents or other solvents «

The steam used to moisten the textile and the support can be introduced directly in the form of steam. One can also get satisfactory results, though a certain amount of liquid is applied to the textile »
