Silk-viscose chiffon reactive printing process

Abstract

The invention relates to a silk-viscose chiffon reactive printing process and belongs to the technical field of reactive printing. The process comprises the steps of printing, drying, steaming and washing, wherein for the printing, slurry is added to perform printing, a 180-mesh pattern plate is used, the tension of the pattern plate is 19 -21 N / cm, and the slurry feeding amount of the pattern plate is 0.09 -0.1 kg / m<2>; and the slurry comprises the following components including, by weight, 0.5 -10 parts of reactive dyes, 0.8 -1.5 parts of dye-resistant salt, 1.5 -2 parts of baking soda, 7 -9 parts of urea, 3 -5 parts of thickening agents and 70-85 parts of water. The front printing and back printing of the silk-viscose chiffon obtained by the process of the invention have consistent color, and the printing is clear and white-free.

Description

technical field [0001] The invention discloses a silk-bonded chiffon reactive printing process, which belongs to the technical field of reactive printing. Background technique [0002] Silk viscose chiffon is a chiffon fabric interwoven with silk yarn and viscose yarn. Silk viscose chiffon has the advantages of both real silk and viscose. It is light and thin in texture, soft in texture, elegant in wearing, and has good hygroscopicity and air permeability. It 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-bonded chiffon printing process has the following problems: [0004] First, silk viscose chiffon has the problem of inconsistent printing colors on the front and back sides. The printing effect of the fabric is dark on the front and light on the back. Silk-bonded chiffon is ofte...

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.
