Problems solved by technology

However, PET 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. The electrostatic phenomenon of polyester fiber not only brings difficulties to the processing of polyester fiber, but also is easy to absorb. Dust reduces the anti-fouling ability, thus limiting the application of PET and its products in some fields

Abstract

The invention discloses a method for preparing an antistatic antibacterial fabric. Firstly, terephthalic acid and ethylene glycol are subjected to esterification reaction to obtain terephthalic acid ester. In the process of continuing to heat up, adding Modifier D and polyethylene glycol, under the effect of catalyst antimony trioxide, terephthalate and modifier D and polyethylene glycol carry out copolymerization reaction, obtained the polyester polyester of modification; Polyester polyester contains a large number of hydrophilic groups, which improves the hygroscopicity of polyester polyester, thereby improving its antistatic properties; in addition, modified polyester polyester introduces quaternary ammonium salts in a chemically bonded manner When making fiber fabrics, the quaternary ammonium salt cations exposed on the surface of polyester fibers are used to absorb water and dissipate the accumulated static electricity. and moisture absorption properties, and the prepared polyester fabric can maintain long-term antistatic and antibacterial properties.

Description

technical field [0001] The invention belongs to the technical field of fabrics, and in particular relates to a preparation method of an anti-static antibacterial fabric. Background technique [0002] Polyethylene terephthalate (PET) has a rigid and flexible coexistence structure due to the rigid benzene ring and flexible aliphatic hydrocarbon group contained in the structural unit. However, the ester group directly connected to the benzene ring forms a rigid conjugated system with the benzene ring, which restricts the free rotation of the flexible segment connected to it. Therefore, polyester is a rigid polymer with coexistence of rigidity and flexibility. The structure of polyester determines that its fibers have excellent physical and mechanical properties, such as high breaking strength and modulus, good thermal properties and dimensional stability. However, PET fiber is a typical hydrophobic fiber, with a moisture regain of only 0.4%, poor wearing comfort, and easy to a...
