Abstract

The invention relates to a finishing method for improving the hydrophilicity of a polyester fabric. Polyethylene glycol serving as a graft monomer is subjected to grafting reaction on a polyester fiber under the initiation of low temperature plasma treatment. The method comprises the following three steps of: impregnating the graft monomer, performing grafting treatment, and performing aftertreatment, wherein in the step of impregnating the graft monomer, the concentration of aqueous solution of polyethylene glycol is 5 to 30 percent, the impregnating temperature is between 20 and 30 DEG C, the impregnating time is 1 to 1.5 hours, and the bath ratio is 1:30-1:50; the grafting treatment is the low temperature plasma treatment, the irradiation atmosphere is argon, the irradiation intensity is 50 to 200W, the irradiation time is 1 to 5 minutes, and the vacuum degree is 20 to 80Pa; and the aftertreatment step comprises washing and drying. By the finishing method, the performance of the hydrophobic polyester fabric is obviously improved, the moisture absorption and moisture transfer performance of the polyester fabric is improved, and the effect that the polyester fabric is comfortable to wear and use is achieved.

Description

technical field [0001] The invention relates to a processing technology of textiles with polyester as the basic material, in particular to a finishing method for improving the hydrophilic property of polyester fabrics. Background technique [0002] Polyester is the largest and most widely used synthetic fiber variety in the world. At present, polyester accounts for more than 60% of the world's synthetic fiber output, and is widely used in textiles such as clothing fabrics, bedding, special fabrics for national defense and military industries, and other industrial fiber products. [0003] The recovery ability of polyester fiber to deformation such as elongation, compression and bending is close to that of wool. It has the advantages of good elasticity, high strength, good heat resistance and good abrasion resistance. However, as a hydrophobic fiber, the moisture regain is only 0.4%, and the moisture absorption Sexual difference becomes the main reason that affects taking perf...
