Embodiment 1

[0044] The chlorine-free bleaching method for polyester fiber knitted fabrics, the bleaching working liquid is composed of 20% by weight of hydrogen peroxide; 33% of acetic acid; 0.5% of sulfuric acid; 0.1% of osmotic scouring agent; the rest is water.

[0045] Bleaching process: The above working solution is prepared according to the above ratio, and the polyester fiber knitted fabric is put into the working solution; the padding car is used to make the weight ratio of the polyester fiber knitted fabric to the working solution be 1:1, at room temperature Stack for 24 hours; wash the polyester fiber knitted fabric, dry it, and test the whiteness.

Embodiment 2

[0047] The method for chlorine-free bleaching of polyamide ester fiber loose fiber, the bleaching working solution is composed of 10% hydrogen peroxide; 15% acetic acid; 0.5% citric acid; 0.1% osmotic scouring agent; the rest is water.

[0048] Bleaching process: The above working solution is prepared according to the above ratio, and the polyamide fiber loose fiber is put into the working solution; the padding car is used to make the weight ratio of the polyester fiber loose fiber to the working solution be 1:1.5, at room temperature After stacking for 48 hours, the piled polyester fiber loose fibers and residual liquid are not washed with water, and kept in a steaming environment at 98~100°C for 90 minutes; the polyester fiber loose fibers are washed with water, dried, and tested for whiteness.

Embodiment 3

[0050]The chlorine-free bleaching method of polyamide ester fiber knitted fabric adopts the working liquid ratio and the method described in embodiment 1, and the polyamide ester fiber knitted fabric is put into the working liquid; The weight ratio of the working fluid is 1:0.6, and stacked at room temperature for 24 hours; the piled polyester fiber knitted fabric and residual liquid are not washed, and kept in a steaming environment at 98~100°C for 90 minutes; The knitted fabric was washed, dried, and tested for whiteness.

Abstract

The invention relates to the technical field of spinning, in particular to a formula of a chloride-free bleaching agent for a polyesteramide textile material and a treatment method of the formula. The formula of the chloride-free bleaching agent for the polyesteramide textile material is characterized by being prepared from the following raw materials: hydrogen peroxide, acetic acid, urea, a catalyst, an activating agent, a stabilizing agent, a penetrating scouring agent and water at a ratio by weight percent of (2%-20%) to (10%-40%) to (0-1%) to (0.2%-5%) to (0-3%) to (0-1%) to (0.1%-0.5%) to (69.5%-87.7%). Compared with the prior art, a chloride-free bleaching solution is adopted for bleaching; the chloride-free bleaching agent is free of damage to equipment and personnel; bleaching treatment can be carried out in an acid environment; the bleaching step is simple and fast; the whiteness of a textile material after bleaching treatment conforms to the requirements of customers; the work efficiency is greatly improved; and meanwhile, the work environment is also improved.

Description

technical field [0001] The invention relates to the technical field of textiles, in particular to the formulation and treatment method of chlorine-free bleaching agents for polyester amide textile materials. Background technique [0002] Polyester fiber has developed rapidly since it entered large-scale industrialization in the 1970s. my country's polyester fiber production ranks first in the world, and it is the textile fiber with the largest domestic production and consumption. The development of polyester fiber, whether it is technical level or production variety, far exceeds other synthetic materials and synthetic fibers. At present, the main goal of polyester fiber is to replace or partially replace natural fibers, especially cotton fibers, to reduce the dependence of textile raw materials on cotton fibers and to alleviate the conflict between grain and cotton. my country developed polyesteramide fiber as early as 2007 (invention patent: application number for the pr...
