Embodiment 1

[0026] A single-sided weft plain knitted fabric anti-curling finishing process:

[0027] (1) Add 2wt% PTF thickener to 73wt% deionized water, stir until uniform paste, then add 25wt% acrylate-modified polyurethane and continue to stir until fully mixed to obtain anti-curling finishing agent ;

[0028] (2) The anti-curling finishing agent prepared in step (1) is evenly applied to the opposite side of the fabric along the grain direction of the knitted fabric (such as figure 1 Applied in the direction indicated by the middle arrow), the applied shape is continuous zigzag (such as figure 2 Shown) scrape coating, the applied thickness is 0.2mm;

[0029] (3) Dry the fabric after anti-curling finishing in step (2) at 80° C. for 3 minutes, and then bake at 150° C. for 3 minutes. The fabric after the anti-curling treatment will not be curled during pretreatment, padding, steaming and soaping.

Embodiment 2

[0031] A single-sided weft plain knitted fabric anti-curling finishing process:

[0032] (1) Add 2wt% PTF thickener to 73wt% deionized water, stir until uniform paste, then add 25wt% acrylate-modified polyurethane and continue to stir until fully mixed to obtain anti-curling finishing agent ;

[0033] (2) Apply the anti-curling finishing agent prepared in step (1) evenly to the reverse side of the fabric along the grain direction of the knitted fabric, the applied shape is continuous zigzag scraping, and the applied thickness is 0.25mm;

[0034] (3) Dry the fabric after anti-curling finishing in step (2) at 80° C. and bake at 150° C. for 3 minutes. The fabric after the anti-curling treatment will not be curled during pretreatment, padding, steaming and soaping.

Embodiment 3

[0036] A single-sided weft plain knitted fabric anti-curling finishing process:

[0037] (1) Add 2wt% PTF thickener to 73wt% deionized water, stir until uniform paste, then add 25wt% acrylate-modified polyurethane and continue to stir until fully mixed to obtain anti-curling finishing agent ;

[0038] (2) Apply the anti-curling finishing agent prepared in step (1) evenly to the reverse side of the fabric along the grain direction of the knitted fabric, the applied shape is continuous zigzag scraping, and the applied thickness is 0.3mm;

[0039] (3) Dry the fabric after anti-curling finishing in step (2) at 80° C. and bake at 150° C. for 3 minutes. The fabric after the anti-curling treatment will not be curled during pretreatment, padding, steaming and soaping.

Abstract

The invention discloses a single-side plain knitted fabric anti-curl finishing technology which is characterized by comprising the following steps of adding deionized water into a thickener, performing stirring until uniform pasty, then adding a stiffening agent, performing continuous stirring until full and uniform mixing to prepare an anti-curl finishing agent; uniformly applying the anti-curl finishing agent to the reverse side of the fabric with the anti-curl finishing agent in a direction of a knitted fabric pattern; and sequentially drying and baking the fabric after anti-curl finishing.The single-side plain knitted fabric anti-curl finishing technology is simple in flow, high in production efficiency and good in anti-curl effect, can reduce the cost and realize industrialized production, is good in production benefit and has a wide application prospect.

Description

technical field [0001] The invention specifically relates to an anti-curling finishing process for single-sided weft plain knitted fabrics, which belongs to the technical field of textile dyeing and finishing. Background technique [0002] my country's traditional knitted fabric printing and dyeing process adopts a rope-like intermittent process, which has poor printing and dyeing reproducibility, high consumption of steam, water and electricity, and is prone to quality problems such as wrinkles, scratches and wear defects during the processing. In order to avoid the above problems, open-width continuous printing and dyeing of knitted fabrics has become a development trend, and the curling of knitted fabrics is one of the key problems to be solved in realizing open-width continuous printing and dyeing of knitted fabrics. At present, the problem of curling of knitted fabrics is mainly solved by changing the structure of the fabric, the performance of the yarn, and mechanical ...
