Abstract

The invention discloses a method for conducting flame-retardant finishing on a polyester fabric by means of a grafted primary amine type phosphorus-containing flame retardant, belongs to the technical field of textile dyeing and finishing, and aims at overcoming the defect that in traditional polyester fabric flame-retardant finishing, the washability is low, or in high-temperature baking, the handfeel and the whiteness of the fabric are prone to be reduced. According to the method, the polyester fabric is pretreated with ester bond hydrolase, and then hydroxyl groups are generated on the surface of the polyester fabric; the hydroxyl groups are made to be converted into aldehyde groups by combining tetramethylpiperidine nitric oxide (TEMPO) and laccase oxidization, flame-retardant finishing processing is conducted on the aldehyde groups and the amino group-containing primary amine type phosphorus-containing flame retardant on this basis, and then flame-retardant finishing of the polyester is achieved. The method comprises the technological processes of polyester pretreating, polyester oxidization pretreating, primary amine type phosphorus-containing flame retardant grafting, washing and treating after drying. The polyester fabric treated through the method has the advantages that the flame retardance can be improved, and the drapability is improved. Compared with a traditional high-temperature baking technology, the flame-retardant finishing method is good in effect and low in energy consumption.

Description

technical field [0001] The invention relates to a flame-retardant finishing method for polyester fabrics by grafting primary amine phosphorus-containing flame retardants, which is characterized in that the modification of polyester fibers is catalyzed by a biological method, and primary amine phosphorus-containing flame retardants are grafted on the surface. The invention discloses a method for imparting flame retardancy to polyester fabrics, belonging to the technical field of textile dyeing and finishing. Background technique [0002] Flame-retardant textiles have long been used in special industries such as fire protection and the military. In recent years, with the development of science and technology and the improvement of living standards, people's safety awareness has become stronger and stronger, and the flame-retardant requirements for fabrics for daily wear and interior decoration are also increasing. come higher. In order to reduce the loss of people's life and ...
