Embodiment 1

[0027] (1) Component A is composed of low-viscosity polyethylene terephthalate and nano-copper. The intrinsic viscosity of low-viscosity PET is 0.5dl / g, and the average particle size of elemental copper is 0.3u. The proportion is 0.2%.

[0028] Component B is composed of high-viscosity polybutylene terephthalate and nano-zinc oxide. The intrinsic viscosity of high-viscosity PBT is 1.1dl / g. Nano-zinc oxide is rod-shaped active zinc oxide. The mass proportion in component B is 0.8%.

[0029] (2) Two-component composite spinning equipment is used: component A and component B are mixed uniformly in a mass ratio of 1:1, melted by a screw, and then the spinning of component A and component B is carried out by a metering pump. The melt is transported to the spinning assembly, and simultaneously passes through a distribution system and a spinneret that can prepare a side-by-side structure. The distance between the spinneret hole 2 of component A and the spinneret hole 3 of component ...

Abstract

The invention relates to differential polyester fiber, aims to solve the problems of being low in spinnability and with color during current copper-based antibacterial fiber processing and provides copper-containing bi-component composite antibacterial fiber and a preparation method thereof. Cross section of the bi-component composite antibacterial fiber is of an outer parallel structure, and filament number is 1-3dpf; copper and zinc are composited for bacteria resisting, so that the problem that copper antibacterial fiber is low in spinnability and with color is solved effectively, and copper and zinc are complementary in antibacterial performance.

Description

technical field [0001] The invention relates to a differentiated polyester fiber, in particular to a functional two-component composite fiber and a preparation method thereof. Background technique [0002] Antibacterial fiber is a traditional functional product. Traditional preparation methods include: (1) Mixed-in method: mixing heat-resistant inorganic antibacterial agents containing silver, copper, zinc ions, etc. into polyester, polyamide or polyamide Spinning in acrylonitrile, this type of fiber is antibacterial, has good washability, and is easy to weave and dye; (2) Post-treatment type: the natural fiber is impregnated with organic antibacterial agents such as quaternary ammonium compounds or fatty imides. This method is easy to process, but the washability is slightly poor. [0003] Silver antibacterial has been widely used and well known, but due to the safety of silver antibacterial, silver antibacterial fibers are currently limited in the European and American ma...
