Abstract

The invention relates to a durably antibacterial chromophilic hydrophilic polyester fiber fabric and preparation method thereof, and belongs to the technical field of polyester fiber fabrics. The durably antibacterial chromophilic hydrophilic polyester fiber fabric adopts a double-quaternary ammonium salt modified monomer as a hydrophilic and antibacterial monomer, and a plurality of quaternary ammonium salt groups are contained on the main chain of the polyester fiber molecule; and the durably antibacterial chromophilic hydrophilic polyester fiber fabric adopts 1, 4- dihydroxybutane- 2-sodiumsulfonate as a chromophilic anion-modified monomer, and the sulfonate anion group is positioned on the branched chain of the polyester fiber. The polyester fiber fabric is easy to dye and achieves the comprehensive effect of hydrophilicity, antistatic property and lasting antibacterial property, and has wide application prospect.

Description

technical field [0001] The invention belongs to the technical field of polyester fiber fabrics, and relates to a durable and antibacterial easy-to-dye hydrophilic polyester fabric and a preparation method thereof. Background technique [0002] Polyester fiber is a synthetic fiber obtained by spinning polyester obtained by polycondensation of organic dibasic acid and dibasic alcohol. The polyester fiber produced in large quantities in industrialization is made of polyethylene terephthalate, and the trade name in China is polyester. Polyester fiber has the advantages of high strength, high modulus, good elasticity and light resistance, good dimensional stability, easy washing and quick drying, etc., and is a relatively popular textile material. [0003] However, due to the regular arrangement of the molecular structure of the polyester itself, high crystallinity, large modulus, and lack of polar functional groups, the hygroscopicity of the fiber is very poor. The moisture reg...
