example 1

[0039] Example 1: When washing polyester-cotton blended fabric: 32S T50 / C50 single jersey, pretreatment: scouring, dyeing dark color; adding disperse dyes and other auxiliaries in the washing stage, heating up to 85°C at 2°C per minute, and then Raise the temperature at 1.5°C per minute to 125°C, keep it warm for 40 minutes, cool it down to 80°C at 1°C per minute, drain it directly, and wash it with cold water once; in the cotton dyeing stage, raise the temperature to 40°C, add sodium sulfate, keep it warm for 15 minutes, and then heat up To 60 ℃, add soda ash, keep warm for 40 minutes, drain, wash and neutralize directly after completion.

example 2

[0040] Example 2: When washing polyester-cotton blended fabrics: 40ST65 / C35 thick and thin needles, first pretreatment: bleaching, dyeing light colors; dyeing polyester: adding disperse dyes and corresponding auxiliaries, heating up to 95°C at 1°C per minute, and then Raise the temperature to 130°C at 2°C per minute, keep it warm for 30 minutes, then cool it down to 80°C at 1°C per minute, drain it directly, and wash it with cold water once; dyeing cotton: heat up to 40°C and add sodium sulfate, keep it warm for 15 minutes, then raise the temperature to 60°C ℃, add soda ash, keep warm for 40 minutes, drain directly after keeping warm, wash with water, and neutralize; clean: add detergent RT 1.5g / L, keep warm at 95°C for 15 minutes, drain water after the end, and then heat up to 60°C Keep warm for 10 minutes, drain, and take out the cloth.

Abstract

The invention discloses a method for washing and processing a dyed terylene cotton blend fabric. The method comprises the following steps of: pretreating, dyeing the terylene, dyeing the cotton and washing; the fabric does not have to be subjected to reduction washing after terylene dyeing by controlling temperature variation and the adding time of each aid, and directly adding cleaner room temperature (RT) treatment into a washing process at the same time, so the used quantity of water is saved greatly; and due to the introduction of sewage emission, the time is saved and the production efficiency is improved at the same time.

Description

technical field [0001] The invention relates to a cleaning processing method which takes polyester-containing cotton fabrics as processing objects. Background technique [0002] At present, for the dyeing and finishing of polyester-cotton blended fabrics, in order to ensure the color fastness to washing, the two-bath method is often used for dyeing. wash. The restoration of polyester after dyeing requires the use of alkali and hydrosulfite (reducing substances), which is neither safe nor environmentally friendly, and a lot of water, steam and time are wasted by step-by-step washing. Contents of the invention [0003] In order to solve the above problems, the present invention provides a washing method for polyester-cotton blended fabrics after dyeing. By controlling the appropriate temperature and adding various auxiliary agents, and adding detergent RT in the washing stage, Reducing the reduction cleaning process after dyeing and washing can greatly save water, reduce w...
