Problems solved by technology

Under alkaline conditions, the dyeing rate of nylon is very low, and a large amount of dyes are washed off by water. The dyeing washed off by water stains cotton and nylon, which not only affects the color fastness, but also stains the fibers and affects product quality.

Embodiment Construction

[0011] For the mixed sample, the specification of cotton and polyester nylon composite silk fabric is: JC32XT160D 128X81 57 / 58, the weight is 152g / ㎡, and it is dyed. Take the following steps:

[0012] Pretreatment: adopt continuous pad dyeing equipment, including desizing, bleaching and other steps; in desizing, the concentration of caustic soda is 8-10g / L, the chelating dispersant cm-5 is 2g / L, and the wax remover WR is 4 g / L, the refining agent 88ECO is 4 g / L; in oxygen bleaching, the concentration of 100% hydrogen peroxide is 5.5-6 g / L.

[0013] Shaping: Shaping the pre-treated fabric. The shaping process conditions are: the amount of stabilizer added is 6-8 g / L, the temperature is 200°C±1°C, and the time is 25 seconds-40 seconds.

[0014] Mercerizing: mercerizing the pre-treated and shaped fabrics. The mercerizing process conditions are: the amount of caustic soda added is 180-190 g / L, and the time is 55 seconds to 60 seconds.

[0015] Dyeing with disperse dyes under ac...

Abstract

The invention relates to a combined fabric printing and dyeing process, and particularly relates to a method for dyeing a cotton-dacron-chinlon combined silk fabric, which can be used for well synergizing dyeing conditions, contrary to one another, of cotton, dacron and chinlon, thus producing the high-quality combined silk fabric. According to the specific technical scheme disclosed by the invention, the method for dyeing the cotton-dacron-chinlon combined silk fabric comprises the processes of preprocessing, sizing, mercerizing, dyeing and the like, wherein in the dyeing process, the dyeing is implemented by disperse dyes under an acid condition, and then the dyeing is conducted by activated dyes. The method has the beneficial effects of solving the problems related to the disperse dyes for dacron, permanent acidic dyes for chinlon, the activated dyes for cotton, and solving a series of problems of low color fixing rate, poor color fastness, serious staining, high-efficiency soaping, long process flow and the like of the fabric.

Description

technical field [0001] The invention relates to a composite fabric printing and dyeing process, in particular to a method for dyeing cotton and polyester nylon composite silk fabric. Background technique [0002] Cotton and polyester nylon composite silk fabric not only has the good moisture absorption and breathability of cotton fiber, but also has the advantages of good elasticity, high wear resistance, polyester polymer fiber, high strength, high temperature resistance, etc., and is widely used in various Apparel fabrics are deeply loved by consumers. However, because polyester, nylon, and cotton fibers have different structures and different dyeing properties, dyeing often brings problems such as color registration difficulties and long process flow to enterprises. In terms of dyeing, the best dyes for nylon are acid dyes, but under acidic conditions, reactive dyes basically do not color cotton fibers, and reactive dyes must be fixed under alkaline conditions. Under al...
