Problems solved by technology

This process has the following disadvantages: because the silk fiber is acid-resistant and not alkali-resistant, although the above-mentioned traditional process does not use sodium hydroxide strong alkali in the pretreatment of degumming, but uses weakly alkaline soda ash, but even so will be affected by the reaction conditions. Severe damage to the strength of silk fibers
In addition, the reactive dye long-car pad dyeing process is prone to quality defects such as contamination, scratches, and folds

Embodiment Construction

[0014] The present invention is further described below.

[0015] In the package oxygen bleaching treatment step, do not carry out mercerizing treatment process, so as to avoid hydrolysis of real silk fiber after encountering strong alkali, and the strength will be damaged and reduced.

[0016] In the package dyeing step, after the dry cloth is rolled, the dry cloth can be idling (that is, not dyed first, rotated to observe whether there are defects and wrinkles on the cloth surface) for one pass to observe the quality of the cloth surface and remove wrinkles.

[0017] In the package dyeing step, the method of adding dyes and auxiliaries while driving can be adopted.

[0018] In the package softening treatment step, when configuring the softening treatment liquid, first add neutralizing acid to adjust the pH value of the water to 3-4, and then add various softeners. During treatment, the gray cloth is transferred from the softening treatment solution for 1 to 3 passes.

Abstract

The invention provides a dyeing and finishing method of a real silk / cotton intertexture, and belongs to a dyeing and finishing method of a fabric. The method comprises the following steps of: a, performing sewing and singeing treatment on a gray fabric; b, packaging and de-sizing; c, performing package and oxygen bleaching treatment, and drying; d, packaging and dyeing; e, packaging and softening; and f, performing preshrinking treatment to finish dyeing and finishing, wherein the warp and weft shrinkage rates of the fabric are less than 3 percent after the preshrinking treatment. Because biological de-sizing, scouring and degumming processes are adopted in the dyeing and finishing method, the method has the advantages of high efficiency and mild reaction conditions; particularly, because protease for degumming is adopted, powerful damage to real silk fibers is low, and the degumming effect is good; and by adopting a jig dyeing process, the quality problems of contamination, scratch, pleat and the like easily produced in a long-vehicle pad dyeing process can be effectively avoided.

Description

technical field [0001] The invention relates to a method for dyeing and finishing fabrics, in particular to a method for dyeing and finishing real silk / cotton interwoven fabrics. Background technique [0002] Silk / cotton interwoven fabric combines the best properties of silk and cotton. Cotton fibers are soft, moisture-absorbing, and have good warmth retention properties, while silk fibers have the characteristics of luxurious appearance, smoothness, and good luster, and have an elegant feeling. Since silk and cotton have different physical and chemical properties, both dyeing and finishing should be considered. [0003] Silk fiber belongs to protein fiber, if the pH value of the solution is too high or too low, if the pH value is above 11 or below 2, the strength of real silk fiber will decrease significantly. Therefore, the finishing process should be carried out under mild conditions, avoiding contact with strong acid and strong alkali, otherwise it will easily cause br...
