Problems solved by technology

When ordinary polyester is dyed, usually only disperse dyes can be used for dyeing, and it must be carried out under the conditions of high temperature and high pressure or with the help of a carrier, so it is greatly limited in terms of energy saving, vividness of dyeing color, and chromatographic width.

Abstract

The invention discloses chitosan-organosilicone modified polyester fiber knitted fabric and a preparation method thereof. The preparation method comprises the following step: step one, preparing a modifying auxiliary agent; to be specific, dispersing chitosan in an acetic acid solution with vinyl siloxane, adding hydrogen peroxide dropwise, carrying out ultrasonic degradation, adding a mixing solution of vinyl siloxane and cetylpyridinium bromide, and carrying out neutralizing to realize a neutral state; step two, putting a polymer polyester fiber filament into a modified auxiliary for immersion, adding alkyl glycoside and a protective agent, and then carrying out drying to obtain a modified polyester fiber filament; step three, carrying out weaving by using a circular knitting machine; and step four, dyeing a piece of grey cloth and carrying out arrangement to obtain chitosan-organosilicone modified polyester fiber knitted fabric. The prepaqred chitosan-organosilicone modified polyester fiber knitted fabric has advantages of diversified styles, rich and bright colors, long-lasting performances, high stability and color fastness, and good low-temperature dyeing effect and has functions of moisture absorbing, quick drying, fuzzing and pilling prevention, and static electricity prevention; and thus requirements of green environmental protection are met.

Description

technical field [0001] The invention relates to the technical field of knitted fabrics, in particular to a polyester fiber knitted fabric modified by chitosan-organic silicon and a preparation method thereof. Background technique [0002] Polyester fiber is ordinary polyester, which is made from polyterephthalic acid (PTA) or dimethyl terephthalate (DMT) and ethylene glycol (EG) through esterification or transesterification and polycondensation reactions. Fiber-forming high polymer-polyethylene terephthalate (PET), a fiber made by spinning and post-processing. Because polyester has excellent properties such as high strength, good elasticity, good shape retention, and high dimensional stability, the clothes woven from it are durable, have good electrical insulation, are easy to wash and dry quickly, and have the reputation of "washable and wearable". Therefore, it is widely used in clothing, decoration, industry and other fields. It is the largest and most widely used synthe...
