CN104631097A - Low-base short-process pretreatment environment-friendly process for polyester-cotton fabrics - Google Patents

Abstract

The invention relates to a low-base short-process pretreatment environment-friendly process for polyester-cotton fabrics. The process specifically comprises the following steps: (1) performing the following process flows, namely performing dipping twice and padding twice on the fabrics in a working solution (the liquid padding rate is 85 percent, and the room temperature steaming time is 50 minutes), performing hot washing once, performing cold washing once and drying for standby testing; and (2) preparing the working solution by a formula, wherein the working solution comprises 1-14Mg/L dioxygen, a 1-6g/L scouring agent, an 1-20g/L accelerant, 1-2pcs/L sodium silicate and 1-60mg/L ferrous sulfate, and the pH value regulated by caustic soda is 8-8.5. According to the low-base short-process pretreatment environment-friendly process for the polyester-cotton fabrics, the cotton fabrics can be treated in an environment-friendly mode, and the process is simple and convenient to use and is suitable for popularization in various enterprises, so that energy conservation and emission reduction are realized.

Description

Polyester-cotton fabric low alkali short route pre-treatment environment-protective process

Technical field

The present invention relates to polyester-cotton fabric low alkali short route pre-treatment environment-protective process, belong to COTTON FABRIC technical field.

Background technology

Textiles short-flow pre-treating process in shortening dyeing and finishing processing method flow process, reduce energy consumption, improve semi-products quality and to reduce costs etc. in, played extremely important effect; But, short-flow pre-treating process, due to the impurity such as slurry, cotton wax, pectin that original pre-treatment three-procedure will need be removed, concentrates in one-step or two-step and removes, therefore must adopt the method for intensive treatment, as improved the consumption of caustic soda and hydrogen peroxide, and add various high effective additives; Therefore, although short-flow pre-treating process has saved the time, in highly basic bath, the decomposition rate of hydrogen peroxide has obviously increased, and the possibility of polyester fiber damage increases, and process conditions need strict control; In addition after short route pre-treatment, cloth cover pH value is high, needs massive laundering, and wastewater flow rate is large, alkalinity is high is also unfavorable for environmental protection; Most short-flow pre-treating process, due to impurity elimination weak effect, therefore, be mainly used at present containing the lower polyester cotton of cotton ratio, and in low-temperature activation oxidation short-flow pre-treating process there is expensive problem in required active oxidation agent.

Summary of the invention

The object of the present invention is to provide a kind of polyester-cotton fabric low alkali short route pre-treatment environment-protective process, more to process for COTTON FABRIC to environmental protection.

To achieve these goals, technical scheme of the present invention is as follows:

A kind of polyester-cotton fabric low alkali short route pre-treatment environment-protective process, specifically comprises the following steps:

(1) technological process: fabric two soak two roll working solution (pick-up 85%, room temperature decatize (50min)-hot water wash once-cold wash once-dry to be measured;

(2) Working solution prescription: dioxygen (Mg/L): 1 ~ 14; Scouring agent (g/L): 1 ~ 6; Promoter (g/L): 1 ~ 20; Waterglass (pcs/L): 1 ~ 2; Ferrous sulfate (mg/L): 1 ~ 60; PH value (regulating with caustic soda) 8 ~ 8.5.

This beneficial effect of the invention is: this polyester-cotton fabric low alkali short route pre-treatment environment-protective process, can process for COTTON FABRIC to environmental protection more, and technical process is simple, easy to use, is adapted at each business enterprise expand, thus energy-saving and emission-reduction.
