A finishing method for solving the lateral elasticity of polyester-cotton knitwear and large chemical fiber brushed fleece

Abstract

The invention discloses a finishing method for solving the transverse elasticity of large chemical fiber brushed fleece of polyester-cotton knitted fabrics, belonging to the technical field of finishing methods of polyester-cotton knitted fabrics. It includes: 1) Softening treatment; 2) Stretch setting and drying after cloth undressing; 3) Napping and raising; 4) Stenter wet setting; 5) Stenter setting. Through the above-mentioned finishing method, the appearance requirements of the napped fleece cotton surface are smooth, crisp and clean, the suede is thick and dense, without blemishes and hair loss, and the internal quality of the ring transverse stretching requirement of more than 150% is achieved. index.

Description

technical field [0001] The invention belongs to the technical field of finishing methods for polyester-cotton knitted fabrics, and in particular relates to a finishing method for solving the transverse elasticity of large chemical fiber brushed flannelettes for polyester-cotton knitted fabrics. Background technique [0002] The conventional 65 / 35 polyester-cotton brushed fleece combines the style of polyester and the strengths of cotton fabrics. The clothes are not only good in warmth retention, comfortable to the touch, but also have the characteristics of stable size, easy washing and quick drying, etc., which are well received by consumers. Favored, it occupies a very important position in knitted garment fabrics. [0003] The current 65 / 35 polyester-cotton brushed fleece fleece yarn is generally made of air-spun medium chemical fiber. According to the conventional napping finishing method, the gray cloth is dyed and softened. After the cloth is straightened, it is direct...

Problems solved by technology

However, this polyester-cotton napped fleece made of chemical fiber in air-spinning, although the conventional napping finishing method can meet the horizontal stretching requirements of the napped sample cloth provided by the customer, it is difficult to touch the napped surface by hand. Plush detachment is mainly made by air spinning during chemical fiber spinning. The twist is not high and it is easy to fluff, and the quality of the raw material and cotton during spinning is not high, so it also contains a certain degree of foreign fibers. If there are flaws, serious stains will penetrate to the surface of the cloth and affect the overall appearance of the finished garment

Therefore, the fleece yarn of polyester-cotton brushed flannelette is made of high-quality cotton when spinning, and the large chemical fiber of ring spinning is used to avoid the problem of hair loss and defects, but the polyester of large chemical fiber Cotton brushed fleece is finished by conventional brushing methods. Although the pile is thick and dense without any blemishes or hair loss, the surface of the cloth is tight and cannot meet the quality requirements of more than 150% of the horizontal stretch requirement of the sample cloth.
