Problems solved by technology

[0003] The end of the yarn surface of the gray cloth of woven rayon has messy fluff. The messy fluff will affect the dyeing effect of the dye during dyeing, and it is easy to cause color difference on the dyed cloth surface. If the messy fluff is not removed, the fabric will be damaged. Pilling occurs during use, seriously affecting the appearance and feel

Embodiment 1

[0030] Embodiment 1, a kind of woven rayon dyeing process, such as figure 1 As shown, including pretreatment, dyeing and post-setting in sequence.

[0031] The pretreatment method is specifically: S1, singeing, the gray cloth is quickly passed through the combustible gas flame in the gas singeing machine to burn the fluff on the cloth; S2, oxygen bleaching, in the high temperature and high pressure overflow dyeing machine Pass through the mixture of soda ash, hydrogen peroxide and biological enzymes, and then put the cloth obtained in S1, the temperature is controlled at 90-100°C, and the time is 30-40 minutes; S3, wash the cloth obtained in S2 twice, or in a sand washing machine Put a mixture of soda ash, hydrogen peroxide, and biological enzymes into the water, and then put the fabric obtained in S1, the temperature is controlled at 95°C, and the time is 40-50 minutes; after sand washing, wash once with hot water at 80°C, and then wash once with cold water. cloth.

Abstract

The invention relates to the technical field of printing and dyeing, and discloses a woven steaple reyon fabric dyeing process. The woven steaple reyon fabric dyeing process successively comprises pretreatment, dyeing and post boarding. The specific method for the pretreatment comprises the following steps: S1, singeing, rapidly singeing piles on cloth flatly by combustible gas flame in a gas singeing machine; and S2, feeding a mixture of soda ash, hydrogen peroxide and biological enzyme in the cloth in step S1 to wash the cloth. A woven steaple reyon fabric is subjected to singeing treatmentbefore printing and dyeing to remove disordered piles on the surface of the cloth, the dyeing effect is improved, fuzzing and pilling of the cloth are improved, the woven steaple reyon fabric is subjected to oxygen bleaching after singeing, thus, slightly burnt portions generated during singeing of the cloth are bleached, and the degree of whiteness and clearness of the cloth is increased.

Description

technical field [0001] The invention relates to the technical field of printing and dyeing, in particular to a woven rayon dyeing process. Background technique [0002] Rayon is a common name for cotton-type man-made staple fibers. The main varieties are cotton-type viscose staple fibers that are chemically processed and spun from natural polymer materials such as cellulose or protein. Its specification is similar to that of cotton fiber, and its length is generally 35mm. The fineness is 1.5-2.2dtex. It can be purely spun on a cotton spinning machine to form woven rayon, or it can be blended with cotton or cotton-type synthetic fibers to obtain polyester, nylon, etc. [0003] The end of the yarn surface of the gray cloth of woven rayon has messy fluff. The messy fluff will affect the dyeing effect of the dye during dyeing, and it is easy to cause color difference on the dyed cloth surface. If the messy fluff is not removed, it will cause fabric Pilling occurs during use,...
