Description

Method of making fancy fabrics The present invention relates to a method for the production of effect fabrics, the warp of a Polyester-cotton blend yarn is made in which the warp yarn is combined with a Dye and sizing bath is treated, which is a combination sizing of 70 up to 100% water-soluble, synthetic polymers and 0 to 50% carboxymethyl cellulose, Contains reactive dyes and disperse dyes, then dried on one Warp beam wound up, woven with a different colored or undyed weft yarn is and the fabric obtained a dry heat treatment and then a Is subjected to alkali treatment.

Effect fabrics within the meaning of the present invention are fabrics that by interweaving a dyed warp yarn with another colored or undyed one Weft yarn can be obtained. If a different colored weft yarn is used, so are Fabrics get the shimmer, d. H. different depending on the viewing angle Color nuances demonstrate. When using an undyed weft yarn, so-called "denim" or Preserved "jeans" fabric. According to the prior art, such Fabrics made by dyeing yarns on note trees or cheeses, after dyeing, sizing and then the warp beam with a different colored one or undyed weft yarn. This conventional method is with one high workload associated with dyeing the note trees or cross-bobbins according to the exhaust process, d. H. so must be done discontinuously. This operation, which is not only time-consuming, but also, like all exhaust processes, not optimal Dye yield allows and also carried out in expensive dyeing machines is a must for the production of effect fabrics in large quantities heavy burden. Attempts have therefore already been made to reduce this additional Replace the dyeing process with other working methods.

For the production of effect fabrics such. B.

Denim items made from pure cotton yarns already have size dyeing processes found its way into practice.

So z. B. the naphthol sizing process (compare sample card F71 from HOECHST AG, dyeings with Naphtol AS brands for denim articles ") to which the naphthol component of the sizing liquor is added and after weaving of the warp yarn treated in this way with a naphthol-free weft yarn, we developed the fabric obtained with a diazo compound.

The coatings used here consist of combinations of native or modified starches and carboxymethyl cellulose, it is also scanned, in an analogous manner, size dyeing process based on reactive, leuco vat ester as well as sulfur dyes for dyeing cotton warp yarn, The Transfer of the known sizing dyeing process to the processing of mixed yarn @@ made of polyester and cotton fibers, is not feasible.

Mixed yarns made from these fibers could be dyed from dye liquors, which contain selected reactive and disperse dyes at the same time0 There are also known dye mixtures and also commercially available from reactive and disperse dyes, ' dio are directly suitable for the production of such dye liquors. If you try analog the sizing dyeing process known for cotton, such mixed dyes in combination with starch-based clothing liquors for dyeing cotton-polyester blended yarns apply, it turns out that the polyester content of the yarn is only extraordinary sohwaoh is stained. A large part of the disperse dye is not fixed, but in the subsequent wet treatments of 'the textile material washed down. This non-iixed part of the dye does not constitute just one considerable loss, but must also be recovered from the washing water of the dye works removed. Because of the disadvantages outlined, it has not been possible until now Produce effect fabrics from cotton-polyester blended yarns in the same simple way, as it is known for effect fabrics made of pure cotton.

It has now been found that effect fabrics whose warp is made of polyester-cellulose fiber blended yarn exists, can be produced in a simple advantageous manner in that the warp yarn is treated with a combined dye and sole bath that i. 3 to 10 percent by weight of a combination size from a) 70 to 100% water-soluble, synthetic polymers and b) 0 to 30 dO carboxymethyl cellulose, 2. up to 4 percent by weight Reactive dyes and 3. up to 4 percent by weight disperse dyes contains, then dried, wound on a warp beam and covered with a different colored one or undyed weft yarn is woven, the fabric obtained is subjected to a dry heat treatment and then subjected to alkali treatment.

The combined dye and sizing bath contains. preferably 4 to 7 percent by weight of the combination size. The dye concentration in the combined dye and sizing bath depends on the desired depth of color the effect fabric to be produced and the color strength of the dyes used. For the production of pastel-like nuances, 0.2% of strong dyes can be used in the combined dye and size baths are sufficient. For the production deeper full dyeings of the warp yarns one works on the upper limit of the indicated Concentration range of dyes, reactive dyes and disperse dyes are chosen in such a way that dyeings are carried out on the two types of fibers, cotton and polyester receives the same nuances; the concentrations of reactive and disperse dyes are adjusted in such a way that the same coloration results on both types of fiber, preferably one works according to the process according to the invention with a combined dye and size bath containing 0.3 to 3 percent by weight of the reactive dye and 0.3 to 3 percent by weight of the I) is dispersion dye.

Preferred combination sizes, those in the to be used according to the invention Dye and size baths are used, contain 75 to 90 percent by weight of water-soluble, synthetic polymer and 10 to 25 weight percent carboxymethyl cellulose. as water-soluble, synthetic polymers suitable for use according to the invention are possible: polyvinyl alcohols, partially saponified polyvinyl acetate, polyacrylic acid, Polymethacrylic acid, copolymers of acrylic acid or methacrylic acid with their Lower alkyl esters, nitriles or amides, polyacrylamide and copolymers of acrylic or methacrylic acid and its derivatives with vinyl or allyl sulfonic acids the acidic groups of the polymers mentioned can also be present in the form of salts.

Since raw yarns are sized, the addition of a is recommended non-abrasive wetting agent, for example based on an alkane sulfate.

The treatment of the yarn with the combined dye and sizing bath takes place preferably between 60 and 80 ° C.

After passing through the dye bath, the yarn is dried, for example by hot air or by contact heat z. B. on Teflonized drying cylinders and then wound up on a warp beam.

Then the material is coated with a different colored or uncolored Weft interwoven. The fabric obtained is used to fix the disperse dye subjected to a heat treatment. The heat treatment is expediently continuous carried out, for example by hot air on a stenter frame or by contact heat, by contact with a healed roller. The duration of the heat treatment is determined depending on the type of disperse dye used and the required depth of color, It is generally 30 to 90 seconds. The temperature at which the heat treatment is carried out also depends on the type of disperse dye used depends and is between 180 and 2300C. When using technically valuable disperse dyes with high sublimation fastness, the fixation is generally achieved by heating 200 to 2200C for 60 seconds.

After the disperse dye has been fixed, the fabric can, if required to be singed.

The reactive dye component is fixed by means of an alkali treatment. This can be carried out continuously or discontinuously. As an alkali are generally the alkali hydroxides, preferably sodium and potassium hydroxide used.

These alkalis are applied in the form of aqueous solutions, except usually contain sodium silicate or common salt in addition to the alkali itself.

Commonly used are e.g. B. Alkali solutions containing 15 to 70 g per liter preferably 30 to 45 g of sodium hydroxide and 700 to 900 ml of sodium silicate solution (Water glass) from 37 - 400 BU or instead of the sodium silicate solution 200 to 300 g, preferably 250 g, of table salt contain.

It is particularly useful to carry out the fixation continuously of the reactive dye. This takes place after the disperse dye has been fixed by passing the tissue through a boiling alkali solution for 8 to 10 seconds. However, the goods can also be impregnated with the cold alkali solution and then impregnated be dampened.

There is another possibility of fixing the reactive dye content in it, the tissue at room temperature with a water glass, alkali hydroxide solution of Above mentioned concentration area to plop, to dock and after a Dwell time of at least 5 to 6 hours, preferably when using sodium silicate about 20 hours to rinse and soap at boiling temperature. Are preferred for Fixing of the reactive dye content continuous process.

After the dyes have been fixed, the tissue is passed through in Rinse and boiling soap baths cleaned. Then the goods can be natural or equipped with synthetic resin and sanforized.

The effect fabrics obtained by the method according to the invention have excellent fastness properties, in particular they are characterized by a excellent light, wash and sublimation fastness. Compared to the previously known Process for the production of effect fabrics from polyester-cellulose fiber blended yarns the method according to the invention is characterized by its simplicity and its high level of accuracy Dye utilization off.

The method according to the invention makes a particularly complex one and time-consuming process part of the known processes, namely dyeing of warp yarns avoided in apparatus. However, the method of operation according to the invention offers in addition, the advantage that they are carried out fully continuously can, the dye is used much better and the wastewater considerably is cleaner.
