Problems solved by technology

[0002] At the present stage, yarn-dyed silk jacquard fabrics have smooth hand feeling, good drapability, soft luster, and highlight the grade, but they are relatively expensive. At the same time, traditional yarn-dyed silk jacquard fabrics must be dyed first and then jacquard. Weaving effect, high energy consumption, but low efficiency
Therefore, people use cotton yarn and real silk to interweave silk-cotton jacquard fabrics to form jacquard fabrics. Although silk-cotton jacquard fabrics can be dyed to achieve dyeing and weaving effects, the impurity treatment method in cotton yarns will damage real silk, and cotton fabrics feel stiff, which is not as good as silk jacquard. Fabric is silky and shiny with a downgrade
Although the price of the silk-cotton jacquard fabric is lower than that of the all-silk fabric, its drape and softness are not as good as that of the all-silk jacquard fabric.

Embodiment 1

[0022] Width: 108 inches (Silk 22D*4)×(cationically modified Silk 22D*2) / 173×200; forming a satin jacquard yarn-dyed effect of light yellow weft and dark yellow warp surface;

[0023] Use the unmodified silk as the warp yarn and the cationic modified silk as the weft yarn to weave the all-tencel jacquard gray fabric according to the jacquard interweaving method, first unwind, sew the head, and then wash it with water, then use the setting machine to pre-set and roll. To eliminate the internal stress of the all-silk jacquard gray fabric, and then perform a one-bath yarn-dyed dyeing process, which is not treated with an alkali-oxygen one-bath treatment formula to prevent hydrogen peroxide from affecting the cationic modifier.

Abstract

The invention discloses a method for processing a full real silk heterochromatic jacquard fabric. When a gray fabric is woven, a part of real silk yarns are modified real silk yarns treated by a cationic modifying agent; and when the gray fabric is further dyed in a bath, the acid dye has high dyeing rate on the real silk yarns modified by the cationic modifying agent under the condition of the neutral bath, and has low dyeing rate or cannot be dyed on the unmodified real silks, so the contrast effect of deep and light colors or white space is formed. Dyeing can be performed again after the gray fabric is woven, so the production efficiency of the fabric is effectively improved, the energy consumption is saved, the loss of real silks is reduced, and the consumption of real silk raw materials is saved; and meanwhile, different dyeing effects are realized by adjusting the ratio and the distribution of the modified real silk yarns and the real silk yarns in the gray fabric, namely the fabric changes color flexibly.

Description

technical field [0001] The invention relates to a processing method for dyeing full silk jacquard two-color fabrics for home textiles, in particular to a dyeing process for home textiles in which the warp and weft yarns are woven with real silk jacquard fabrics. Background technique [0002] At the present stage, yarn-dyed silk jacquard fabrics have smooth hand feeling, good drapability, soft luster, and highlight the grade, but they are relatively expensive. At the same time, traditional yarn-dyed silk jacquard fabrics must be dyed first and then jacquard. Weaving effect, high energy consumption, but low efficiency.
