Problems solved by technology

In short, most of the existing dyeing and finishing methods of rayon fabrics are directly printed with reactive dyes, and the small floral pattern is acceptable in the market, but when it comes to patterns with dark backgrounds and light-colored small flowers, the printing effect is blurred and rough, with three-dimensional effect. Poor, the market reaction is very unsatisfactory

Abstract

The invention relates to a dyeing and finishing process of viscose woven fabric. The dyeing and finishing process of the viscose woven fabric comprises the steps of dyeing and pretreating a viscose woven fabric semi-finished product: cooking the water-washed viscose woven fabric semi-finished product in a dyeing pretreatment solution, and carrying out discharge print on the sized viscose woven fabric semi-finished product by adopting a mixed dye of vasekine and rongalite, wherein the mass ratio of the rongalite to the vasekine is 1 to 1; adding table salt and sodium carbonate into a rope rinsing machine, wherein the masses of the table salt and the sodium carbonate are equal; placing the dyed viscose woven fabric into a color fixing agent, softening the color-fixed dyed viscose woven fabric by putting into 1g / L of Taigu oil water solution. A discharge print dyeing pattern obtained through the method provided by the invention is high in three-dimensional effect, firm in dye, and good in air permeability.

Description

technical field [0001] The invention relates to the technical field of fabric dyeing and finishing, in particular to a dyeing and finishing process of rayon woven fabrics. Background technique [0002] The dyeing and finishing method of rayon fabric in the prior art is not firm in dyeing, and its air permeability is not good. There are technical deficiencies in the dyeing and finishing methods of rayon fabrics in the prior art that lead to the above problems. For example, patent CN103734918A provides a kind of elastic underwear fabric, including: spandex fiber, cotton fiber and corn fiber; CN103498242A provides a kind of health care underwear fabric, raw materials include Bamboo fiber, cotton fiber and polyvinyl chloride fiber. However, cotton fibers are inevitably used in these underwear fabrics. In short, most of the existing dyeing and finishing methods of rayon fabrics are directly printed with reactive dyes, and the small floral pattern is acceptable in the market, bu...
