Abstract

The invention discloses polyester fiber and a preparation method thereof, and belongs to the technical field of preparation of fiber. The polyester fiber is prepared from the following raw materials of polyethylene terephthalate, polyoxyethylene, nanometer silicon dioxide, ethoxylated glycerin, carbon nanotube, chitosan, an antibacterial modifying additive, a mechanical property enhancing additive, and a silane coupling agent KH-570. The preparation method comprises the following steps of preparing a polyester composition, melting, and spinning, so as to obtain the polyester fiber. The prepared polyester fiber has excellent antibacterial and mechanical properties.

Description

technical field [0001] The invention belongs to the technical field of fiber preparation, and in particular relates to a polyester fiber and a preparation method thereof. Background technique [0002] Due to its excellent properties, polyester is widely used in the fields of fiber, film, plastic and so on. Since its inception, polyethylene terephthalate fiber has a series of excellent properties such as high breaking strength and elastic modulus, moderate resilience, excellent heat setting, good heat resistance and light resistance, acid resistance, alkali resistance and corrosion resistance. The fabric has the advantages of anti-wrinkle, cost-free, and good stiffness, and is widely used in clothing, home textiles and other fields. [0003] The Chinese patent application document "A Polyester Fiber and Its Preparation Method (Application Publication No.: CN105220270A)" discloses a polyester fiber and its preparation method. The polyester fiber contains the following raw mat...
