Problems solved by technology

[0002] Polyester-cotton blended fabric is the most widely used blended fabric in the textile industry, which has the high strength and dimensional stability of polyester fabric, good moisture absorption and perspiration performance of cotton fabric, and excellent thermal performance, but polyester-cotton blended fabric However, it is a difficult problem to strip the color of polyester-cotton blended fabrics. If dyeing defects are found in the dyeing process of polyester-cotton blended fabrics, or it is difficult to achieve color change and re-dyeing, it is difficult to strip the original color. In this case, most of them are discarded or converted into low-grade textiles. use, resulting in a great waste of resources; in the quantitative analysis of products, the existence of color will cause deviations in the analysis results, making the analysis data inaccurate, and the recycling and reuse of polyester-cotton blended fabrics after use will also cause disadvantages. Difficult, the recycling of polyester-cotton blended fabrics is very difficult and limited
[0003] At present, there are few effective stripping methods for polyester-cotton blended fabrics, most of which are not effective, and cannot achieve the purpose of complete stripping, and are still under research

Embodiment Construction

[0062] The present invention will be further described below in conjunction with accompanying drawing:

[0063] figure 1 Shown is the state diagram of the decolorization and dispersion treatment of polyester-cotton blended fabrics. The positions of each part must be correct and the operations should be performed in sequence.

[0064] The amount of chemical substances used in the decolorization treatment of polyester-cotton blended fabrics is determined according to a preset range, with grams and milliliters as measurement units.

[0065] The stripping and dispersing treatment of polyester-cotton blended fabric is carried out in the dyeing test machine under the conditions of heating, pressurization and heat preservation;

[0066]The dyeing tester is vertical. The lower part of the dyeing tester 1 is the machine base 2, the upper part is the machine cover 3, and the inside is the machine chamber 4. The upper right wall of the dyeing tester is provided with an air outlet pipe 7...

Abstract

The invention relates to a stripping treatment method for a cotton-polyester blended fabric and aims to solve the problem in stripping treatment of the cotton-polyester blended fabric. The method comprises the following steps: swelling, dissolving, reducing and stripping the fabric at a high temperature in a dyeing tester, washing and drying, so that the color of the cotton-polyester blended fabric is removed, and the cotton-polyester blended fabric restores to the state before dyeing. The stripping method is advanced in process, detailed and accurate in data, environment-friendly and good in stripping effect, the stripping rate is 94.97 percent, the physical and chemical properties and mechanical property of the stripped cotton-polyester blended fabric are stable, and the method is an ideal stripping treatment method for the cotton-polyester blended fabric.
