Problems solved by technology

[0002] As we all know, polyester fiber has poor decontamination performance
In commonly used laundry methods, such as washing in conventional domestic washing machines or hand washing with bars, it is often very difficult to remove soils from textile materials and, given the removal of unwanted substances from textiles, residues Soil in the water often redeposits on the textile material before the wash cycle is complete, making the textile impossible to wash

Abstract

The invention relates to a decontamination finishing agent used for polyester fiber, and a preparation method thereof. The finishing agent comprises, by weight, 1-5% of a polyester-polyether-polyamide block copolymer, 2-5% of glycerol or ethylene glycol or fluorine resin, and balance of water. The polyester-polyether-polyamide block copolymer is prepared from the raw materials of, by weight: 60-160 parts of polyethylene glycol, 13-40 parts of glycol, 14-26 parts of dimethyl terephthalate, 15-100 parts of polyamide, and 0.2-1 parts of metal acetate as a catalyst. With the in-bath crease-resisting agent provided by the invention, the polyester fiber is provided with good decontamination performance. Also, fluffy and soft texture, antistatic property, hydrophilic smoothness, and the like of polyester fiber can be improved. The decontamination finishing agent has excellent washing resistance, and does not fail after at least 30 times of washing.

Description

technical field [0001] The invention relates to a decontamination finishing agent for polyester fibers and a preparation method thereof. Background technique [0002] As we all know, polyester fiber has poor decontamination performance. In commonly used laundry methods, such as washing in conventional domestic washing machines or hand washing with bars, it is often very difficult to remove soils from textile materials and, given the removal of unwanted substances from textiles, residues Dirt in the water often redeposits on the textile material before the wash cycle is complete, making the textile impossible to wash. Therefore, it is very necessary to modify the polyester fiber before leaving the factory to make it have good decontamination performance. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a stain-removing finishing agent for polyester fibers. [0004] Another technical problem to be solved by the p...
