Abstract

The invention discloses a yarn-dyed silk and cotton warp knitting process and relates to the field of textiles. The key point of the technical scheme adopted by the invention is that the yarn-dyed silk cotton warp knitting process comprises the following steps: (1) material taking; (2) soaking treatment; (3) dyeing; (4) shrinking and shaping: respectively and completely soaking silk threads and cotton threads in mixed liquid with a bath ratio of 1:60 to soak for 20-30 minutes; (5) weaving; (7) after-finishing: placing a fabric in post-treatment fluid with a temperature of 30-40 DEG C to soak for 50-80 minutes, wherein the post-treatment fluid is formed by mixing 6-8 weight percent of 1,3,5-pentane tricarboxylic acid, 3.3-3.6 weight percent of sodium phosphate and 0.3-0.5 weight percent ofa softening agent. The yarn-dyed silk and cotton warp knitting process disclosed by the invention solves the problems that the silk and cotton fabric is easy to dye unevenly and is prone to shrinkageand crimping in water and has creases after folding and achieves the effects that the silk cotton fabric is more evenly dyed, is not easy to shrink and is folding and wrinkle-resistant.

Description

technical field [0001] The invention relates to the field of textile technology, more specifically, it relates to a yarn-dyed silk cotton warp knitting process. Background technique [0002] Cotton cloth is a woven fabric made of cotton yarn, which has the advantages of moisture absorption, heat resistance and alkali resistance; silk is a fabric made of mulberry silk, which is soft, smooth, comfortable, elastic and breathable. Weaving mulberry silk and cotton yarn can weave textiles that are smooth, cool, moisturizing, moisture-absorbing, and breathable. [0003] In the prior art, you can refer to the Chinese invention patent application document with the application publication number CN104846535A, which discloses a smooth silk and cotton blended concave-convex honeycomb jacquard warp knitted fabric, which is composed of 40-50wt% silk, 50- 60wt% cotton blended yarn is woven; the twist of the blended yarn is greater than 900T / m, and the fineness is greater than 60s; the wea...
