Embodiment 1

[0048] Antibacterial polyester fiber preparation steps are as follows:

[0049]Step (1) Add 1mol 5,5-dimethylhydantoin (A) and 1.2mol 1,2-dibromoethane (B) into 50mol N,N-dimethylformamide and heat to 80°C , stirred vigorously for 2 hours, cooled, stood still, and concentrated in vacuo; slowly added 50mol of water, stirred for 30min, then added 80mol of chloroform, stirred for 30min, stood to separate layers, took the organic phase and dried it with anhydrous sodium sulfate, filtered, and rotary evaporated , to obtain the intermediate product I (IR: 1051cm -1 : tertiary amine-C-N-generated; 1672cm -1 : Amide-C=O exists; 644cm -1 :-C-Br exists).

[0050] Step (2) Add 1mol I, 1.1mol quaternary phosphonium salt (C) into 50mol N,N-dimethylformamide, heat to 80°C, stir vigorously for 6h, cool, stand still, rotary evaporate, purify, and dry , to obtain the intermediate product II (IR: 644cm -1 :-C-Br disappeared; 1074cm -1 :-N-N-Existence; 1673cm -1 : Amide-C=O exists; 3100cm...

Abstract

The invention belongs to the field of new materials, and relates to an antibacterial polyester fiber and fabric. The antibacterial polyester fiber and fabric are prepared by taking hydantoin derivatives (A), 1, 2-dibromoethane (B), triphenyl quaternary phosphonium salt (C), epoxy chloropropane (D), terephthalic acid (E) and ethylene glycol (F) as the raw materials through multi-step reactions suchas substitution and polycondensation, a spinning process and a weaving process. The antibacterial polyester fabric effectively overcomes the defect that microorganisms such as bacteria and fungi areprone to breeding after existing polyester is dyed and finished, meanwhile, the antibacterial polyester fabric has high-efficiency flame retardant property and antistatic property, and therefore it can be foreseen that the antibacterial polyester fabric can have a wide market space and is particularly suitable for the fields of clothing and the like.

Description

technical field [0001] The invention relates to an antibacterial polyester fiber and fabric. The invention belongs to the field of new materials. Background technique [0002] Polyester, also known as polyester fiber, or PET fiber for short. Polyester is a cheap and simple synthetic fiber. Due to its advantages of high strength, good elasticity, easy washing and quick drying, etc., it is gradually praised by the market and widely used in clothing, industry, medical and health fields. Due to the rigid benzene ring and flexible aliphatic hydrocarbon group in the polyester structure unit, the fiber has excellent physical and mechanical properties, such as: high breaking strength and modulus, good thermal performance and dimensional stability. However, polyester fiber is a typical hydrophobic fiber, with a moisture regain of only 0.4%, poor wearing comfort, and easy accumulation of charges to cause static electricity. decline, which limits the application of its products in ...
