Description

200521287 IX. Description of the invention: [Technical field to which the invention belongs] The present invention relates to a method for pretreating weaving textiles, which includes the following steps: (a) using a polymer or copolymer solution obtained by Treating a weaving textile, 〇i) polymerize or copolymerize ^^-vinylamidoamine with general formula wherein R is selected from hydrogen and (^ to (: 1 () alkyl, and (a2) if Suitably, partially hydrolyzed, (b) optionally drying the treated textile, and (c) optionally saponifying all or some of the amido groups, wherein at least one of steps (a2) and (c) is performed. [PRIOR ART] Weaver textiles can be dyed by a variety of methods. At present, dyeing is usually performed with reactive dyes, vat dyes or direct dyes. However, the dye uptake rate (that is, the dye transferred from the dyeing solution to the textile) Part) and the fastness of dyeing is not satisfactory. In particular, reactive dyes often produce a dyeing rate significantly lower than 80%. A 95944.doc 200521287

The reason is that, in many cases, the reaction system of the dye fails to reach a sufficient reaction with the OH group of oryzanol. The remaining dye usually goes to a wastewater treatment plant. One particular reason for the often unsatisfactory fastness of dyeing is that not all dyes can adequately fix. When using textiles, it is observed that unfixed dyes are washed off during the consumer's wash. If the chemical bond between the reactive dye and the fiber is broken during the conventional washing operation, even the dye which is obviously sufficiently fixed can be washed off, which causes the washed fabric to fade and stain the adjacent fabric. Currently, dyed textiles are usually treated with a cationic post-treatment agent to specifically increase the fastness of reactive dyes, but this results in additional steps during dyeing or during the dyeing and finishing stages, thus increasing costs. 7th post: Apply cationic post-treatment agent and polyenamine to the weaving of the textile before the dyeing operation. This application can significantly enhance dyeing (Bunt-Denim, TI / T 240 d5 1993 ^, BASF Aktiengesellschait), but in many cases this will produce an undesired ring dyeing phenomenon in which all or some fibers are only on the surface and not the whole The section is evenly dyed. When rough-dyed fibers are subjected to mechanical stress, dyeing tends to be mechanically removed and the fibers quickly take on an undesirable appearance. [Summary of the Invention], and 4, the object of the present invention is to provide a textile fabric pretreatment method, which avoids the disadvantages of the prior art and more specifically provides uniform transfection Π :. Another object of the present invention is to provide a method by which the color is normal and does not leave an excessive load on the dyeing liquid to be removed. 95944.doc 200521287 These objectives can be achieved by the methods defined at the beginning of this article.

Wash under running water for 5 minutes, and then between 20 and 35. (: wash for another 5 minutes and dry at 80 ° C for 20 minutes. Thereafter, in a circulating air drying box in each case Example 0 since without pretreatment The textiles began to implement the control 95964.doc -25 * 200521287 Examples 17 to 24 were generated (Table 3) The dyed textiles of the present invention and the control textiles of Comparative Examples V2 to V6 (Table 4). The textiles of the present invention of Examples 17 to 24 exhibited bright dyeing. The shearing showed that these textiles were different from those of Comparative Examples V2 to V6 The control textiles were uniformly dyed and no ring dyeing occurred. The values of L, A, B, and λE were determined according to CIELAB.
