Problems solved by technology

The PET / PTT / TPEE composite fiber prepared by blending PET, PTT and TPEE can well integrate the advantages of the three and achieve comprehensive performance that cannot be achieved by a single variety, but PET / PTT / TPEE is easy to produce and use. The generation of static electricity will cause hazards such as dust collection and discharge, which will largely limit its application fields; and with the progress of society, people's requirements for fiber comfort, health, safety and environmental protection It is also getting higher and higher, and textile fibers with good antibacterial, environmental protection and functionality are increasingly favored by consumers

Abstract

The present invention discloses an antibacterial and anti-static PET / PTT / TPEE composite fiber, which comprises the following components in mass percentage: 32-63% of PET, 20-25% of PTT, 5-15% of TPEE, 5-15% of nano bamboo carbon, 2-5% of antibacterial agent, 2-4% of compatilizer, 1-3% of antistatic agent, 0.1-0.5% of anti-oxidant and 0.1-1% of lubricant. The antibacterial agent is in the form of silver-carrying ion antibacterial zeolite powders and the particle sizes of the antibacterial zeolite powders are within the range of 0.1-20 mum. The compatilizer is in the form of PS-g-GMA. According to the invention, the composite fiber is excellent in anti-bacterial and anti-static properties. The nano bamboo carbon is modified to be good in antibacterial, deodorizing, purifying and anti-ultraviolet synergistic effects. Meanwhile, the composite fiber is good in softness and anti-pollution performance, thus being applicable to the fields of indoor textures, accessories and fabrics.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to an antibacterial and antistatic PET / PTT / TPEE composite fiber. Background technique [0002] Polyethylene terephthalate (PET) is a crystalline polymer with high melting temperature and glass transition temperature, which maintains excellent physical and mechanical properties in a certain temperature range, and its fatigue resistance , friction resistance, aging resistance, and electrical insulation are extremely prominent, relatively stable to most organic solvents and acids, and have low production energy consumption, so they are widely used in the fields of synthetic fibers, films, and engineering plastics; but because PET Strong rigidity leads to poor toughness of the material, slow crystallization speed, high mold temperature and long molding cycle, etc., which greatly limit its application range. Polytrimethylene terephthalate (PTT) is a crystalline polymer with fa...
