A silk viscose chiffon reactive printing process

Abstract

A silk-viscose chiffon reactive printing process belongs to the technical field of reactive printing. Printing—drying—steaming—washing; among them, printing: adding paste for printing, using a 180-mesh pattern, the pattern tension is 19~21 N / cm, and the size of the pattern is 0.09~0.1kg / ㎡; the slurry includes the following components by weight: 0.5~10 parts of reactive dyes, 0.8~1.5 parts of anti-dye salt, 1.5~2 parts of baking soda, 7~9 parts of urea, 3~5 parts of thickener, 70~5 parts of water 85 servings. The silk-bonded chiffon obtained by the process of the invention has the same color on the front and back of the printing, and the printing is clear and does not show white.

Description

technical field [0001] A silk-viscose chiffon reactive printing process belongs to the technical field of reactive printing. Background technique [0002] Silk viscose chiffon is a chiffon fabric in which silk yarns and viscose yarns are interwoven. Silk viscose chiffon combines the advantages of silk and viscose, with light and thin texture, soft texture, elegant wearing, good moisture absorption and breathability, and occupies an important position in high-end clothing fabrics. However, due to the characteristics of silk-bonded chiffon fiber and its light texture, it is difficult to print. [0003] The applicant found in the research that the existing silk viscose chiffon printing process has the following problems: [0004] First, silk viscose chiffon has the problem of inconsistent color printing on the front and back, and the fabric printing effect is dark on the front and light on the back. Silk viscose chiffon is often used as a silk scarf. When it is folded and wo...

AI Technical Summary

Problems solved by technology

[0004] First, silk viscose chiffon has the problem of inconsistent printing color on the front and back. The printing effect of the fabric is deep on the front and light on the back.

Silk-bonded chiffon is often used as a silk scarf. When folded and worn, the light-colored part of the reverse side is exposed, which affects the appearance and lowers the grade.

Second, when silk-bonded chiffon is used for reactive printing, there are problems of false, fuzzy, and white patterns; the chiffon fabric is thin, light-transmitting and has large gaps, and the weaving characteristics of the fabric make printing difficult; third, silk-bonded snow Spinning is too thin, elegant, and has poor adhesion to equipment. The problem of staining is prone to occur in the printing process, and stained silk-bonded chiffon cannot be sold.

Fourth, compared with pure silk chiffon, the viscose component in silk-bonded chiffon is weaker in wet state, which makes silk-bonded chiffon prone to washing damage when washed.

Fifth, when using flat screen printing, set the rectangular pattern above the fabric, the pattern does not move the fabric, and repeat the steps of printing - radial movement of fabric - printing again until all fabrics are printed; silk-bonded chiffon It is prone to the problem of difficult connection (that is, the pattern is not continuous between two printings), especially when the pattern is a repeating unit extending along the warp direction. In theory, multiple radial continuation patterns should be parallel to each other, but In fact, there is a problem that multiple radially continuous patterns are not parallel. After the silk-bonded chiffon fabric is unfolded, obvious traces of plate connection can be seen.
