The invention relates to a method for the irregular dyeing of zelluloseh'altigem yarn, in which Dye liquid is injected into at least one place in a winding of yarn, so that the yarn dyed and receives uncolored areas of different lengths. Textile fabric ^ made from such yarn have a completely irregular, non-repeating pattern. Specks of color in their Size fluctuates, appears anywhere on the panel, and a fixed pattern, such as B. a Zigzag or a striped pattern or the like does not arise.

It has long been known to dye cellulosic yarn irregularly by using dye liquid is injected into a package of yarn at various points, e.g. B. the Austrian U.S. Patent 104,379 shows. So far, noun dyes have always been used. The received However, yarns were not washable and colourfast. When washing such yarns or the ao In the manufactured textiles, the colors run together or into one another and the dye bleeds out into the wash water, causing fading of the colored areas and discoloration of the whole Yarn or textile occurs.

Furthermore, reactive dyes have long been known which react chemically with cellulosic yarns enter and show a high wash resistance. However, these reactive dyes have always been for dyeing yarns or fabrics in a dye bath or the like. Used.

The object of the present invention is to provide a method for irregular dyeing of cellulosic yarn, due to which the unsatisfactory obtained when injecting noun dyes Results are improved.

According to the invention, this object is achieved in that the dye liquids are an aqueous solution contain a dye and alkali which undergo a chemical reaction with the cellulose fiber and that the yarn package after injecting the dye liquids, preferably at a temperature from 20 to 25 ° C are used as long as Left to itself until the dye has chemically reacted with the yarn and preferably afterwards is cleaned and dried.

It has surprisingly been found in the process according to the invention that reactive dyes can be used in the injection method for the irregular dyeing of yarns without the reaction products occurring during the chemical reaction of the dye with the cellulose fiber

Cause damage to the fiber or leave other harmful excretions or residues, although when the dye liquid is injected, the reaction products are not from the liquor be included, as is the case with the known dyeing processes with reactive dyes. It was also found, surprisingly, that the reactive dye in the process according to the invention in spite of the strongly changing concentration ratios in the injected area the cellulose fiber reacts.

The method according to the invention offers the advantage that the colors also run together or into one another is avoided during washing and that the products obtained are completely colourfast and washable. That The method according to the invention thus represents a significant technical advance in the field of irregular dyeing of cellulosic yarns and has extremely rapid and wide application found.

In the method according to the invention, dye liquids can be present at various points on the yarn package different color can be injected. Since follow-up treatment is not required, there is no mutual interference between the various dye liquids.

A wetting agent is expediently added to the dyeing liquid in a manner known per se.

The dyeing process according to the invention is also extremely cheap, since expensive means, e.g. B ". Printing and Dyeing machines, lengthy and cumbersome processes, e.g. B. hanging and removing the Strands of yarn, the costly production of the pressure rollers, can be avoided and only cheap injection media, z. B. a syringe and a needle are required.

The listed .Färbeflüssheiten can all be wrapped in a cellulose yarn that z. B. has a conical or tubular shape, are injected. Of course, the amount of dye injected can be varied. It depends on the desired ratio of dyed yarn to undyed yarn. It has been shown that 10 to 100 cm ^{3 of} the dye liquids listed lead to satisfactory results per 0.45 kg of yarn. Some of the staining methods are described below:

2.2 kg of undyed cotton yarn (7300 m, 4/2) are wound onto a cone 10 in the Foster manner. The resulting wrap is of medium density, 19 cm high, and has on top End 20 cm and at the lower end 24 cm in diameter.

50 cm ^{3 of} the dye liquid from example a) are filled into a syringe which is provided with an injection needle. The latter has a diameter of 0.02 cm and has openings distributed along its length. The needle is inserted into the thread package until its point touches the cone 10. The dye is then injected from the syringe into an area 12 of the thread package.

The lap inoculated in this way remains standing for 24 hours so that the dye can react chemically with the yarn.

The yarn is then machine cleaned by a cold wash process until the unreacted dye is removed; The yarn is then rinsed twice for 15 minutes with water having a temperature of about 8O ⁰ C. The water is extracted from the yarn package by means of compressed air. Subsequently, the yarn package is dried for 6 hours at 110 ⁰ C on the machine.

The dry yarn is then wound onto paper cones and can then be shipped.

There are different methods from the invention To produce yarn webs that have randomly distributed color areas. So can the yarn z.

Also woven Sheets can be made from the yarn of the present invention, either warp or can form the wefts or both. In addition, colored or undyed warp or Weft threads are woven into it in any way.

These webs can also be over-dyed if desired.
