Problems solved by technology

②Put the dried fabric through the rollers of the sizing machine for padding treatment: temperature 140°C, speed 18m / min, pressure 1-2MaP, liquid retention rate 80-85%. Improve the lightfastness of the fabric, but the washability of the fabric after this method is very poor, and the durability is not strong
However, the fabric treated by this method will damage the cotton fiber and cause a large amount of floating hair to remain on the surface of the fabric, which will affect the comfort after wearing.
In addition, biological hair removal will also significantly reduce the wet rubbing fastness of the fabric

Embodiment 1

[0041] Step S1, prepare mercerized high-insolation school uniform fabric raw materials: 14.8Kg of 18.2tex compact cotton yarn, 11.5Kg of 150D polyester low elastic yarn, and 14.8Kg of 18.2tex combed CVC blended yarn.

[0042]Step S2: Feed 150D polyester low-stretch yarn blended with pure cotton yarn into the double-sided weft knitting machine at the same time, and bend the yarn into loops, so that the pure cotton yarn is on the outer layer, the blended CVC yarn is on the inner layer, and the polyester The low elastic yarn is used as the connecting yarn to obtain the base cloth.

[0043] Step S3: Put the base fabric obtained in step S2 on the tenter setting machine through the high temperature of rolling liquid to pre-set. Preparation of rolling liquid: heating to 60°C and adding 2kg of penetrant JFC. Shaping temperature material cylinder 100Kg water, 195 ℃, speed 22m / min.

Abstract

The invention relates to a preparation method of a mercerizing-imitating high-light-fastness school uniform fabric, the preparation method comprises the following steps: selecting compact siro spinning pure cotton yarn to prepare gray fabric, and performing singeing mercerizing and alkali shrinkage boiling finishing, so that the mercerizing-imitating high-light-fastness school uniform fabric has the characteristics of mercerizing fabric, the surface of the fabric is smooth, the color is bright, and the anti-pilling effect is improved. The strength of cotton fibers is not damaged, the wet rubbing fastness of the fabric is not affected, the hand feeling is soft, and wearing is close-fitting and comfortable. In the preparation process of the high-light-fastness school uniform fabric, the base cloth is dyed in a high-light-fastness dye solution and treated by Anmeibao PN-2N so that the light resistance of the fabric is fundamentally improved, the solarization is not influenced by water washing, and the durability is high. After Anmeibao PN-2N is used for treatment, little color fixing agent is used, so that the light resistance is improved, the washing color fastness and the dry and wet grinding fastness of the fabric are not influenced, meanwhile, the post-treatment cleaning process is shortened, water, electricity and time are saved, after complexing treatment, water basically reaches the clear degree, and the COD of sewage is obviously improved.

Description

technical field [0001] The invention relates to the technical field of textiles, in particular to a method for preparing a mercerized high-solar school uniform fabric. Background technique [0002] The GB / T31888-2015 standard of "School Uniforms for Primary and Secondary School Students" stipulates that when primary and secondary school students wear school uniforms, whether it is the seaside or the southern region, the fabric of the school uniforms cannot fade after a long period of light. It is required that the sun exposure of school uniform fabrics must reach level 4 or above. In addition, it is also stipulated that the cotton fiber content of the part of the school uniform that directly contacts the skin should not be less than 35%, and the cotton fiber content of the overall fabric should not be less than 65%. It is easy to wrinkle and pill during washing and washing, and the color of cotton fiber after reactive dyeing is darker and not bright, which affects the appea...
