Embodiment 1

[0023] Preparation of PTT / PET composite elastic staple fiber with antibacterial moisture absorption and perspiration: slice and dry PTT and hydrophilic modified PET polyester raw materials, add silver ion antibacterial agent masterbatch to PTT component after drying, and blend the two components Separately input into the two screw extruders of the parallel composite spinning equipment, the metering pumps are respectively metered and then input into the spinning box, and melted and extruded through the specific spinneret assembly with the spinneret hole as a "symmetrical double right angle" structure. , air blowing and cooling, the tow is wound and dropped into the barrel, clustered, then wound after primary drafting and secondary drafting, cut and packed after heat setting, and hydrophilic PTT / PET composite elastic staple fiber is obtained. The composite fiber has a cross-section structure, the mass ratio of PTT and PET is 50:50, and the content of silver ion antibacterial agen...

Embodiment 2

[0025] Preparation of PBT / PET composite elastic filaments with antibacterial moisture absorption and perspiration: PBT and hydrophilic modified PET polyester raw materials are sliced ​​and dried, and the silver ion antibacterial agent masterbatch is dried and added to the hydrophilic modified PET component for blending. The two components are respectively input into the two screw extruders of the parallel composite spinning equipment, and the metering pumps are respectively metered and then input into the spinning box, and the spinneret hole is a special spinneret with a "symmetrical double right angle" structure. The components are melted and extruded, blown and cooled, oiled and integrated into tows, and the tows are drawn, wound, and heat-set to produce hydrophilic PBT / PET composite elastic filaments. The composite fiber has a cross-section structure, the mass ratio of PBT and PET is 50:50, and the content of silver ion antibacterial agent is 1.5%.

Abstract

The invention discloses a polyester composite elastic fiber with antibacterial, moisture absorption and sweat releasing function. The polyester composite elastic fiber has dual-component parallel composite structure and has cross-shaped cross section. Two components of the parallel composite fiber are respectively selected from one of PET, PBT, PTT and CO-PET and are different one another; antibacterial silver ions are added in at least one component. The fiber has natural curly spiral structure due to different shrinking percentage of the two components and has permanent elasticity; the elastic fiber has moisture absorption, sweat releasing and anti-bacterial function due to the fact that the cross-shaped cross section structure is adopted and the antibacterial agent is added. The fiber is widely applicable to the high-grade underwear, sportswear and swimwear and has the characteristics of being elastic, comfortable, breathable, fresh, bacteriostatic and healthy.

Description

technical field [0001] The invention belongs to the field of novel multifunctional polyester fibers, in particular to a polyester composite elastic fiber with antibacterial and moisture absorption and perspiration functions. Background technique [0002] Elastic fibers refer to synthetic fibers with high elongation at break, low modulus and high resilience. Clothes containing elastic fibers not only fit the body shape of the human body, but also increase the aesthetic feeling, and will not restrict the activities of the human body, which meets people's requirements for comfort. Therefore, people are increasingly applying elastic fibers to various fabrics. At present, the most successful commercialized elastic fiber is spandex, which is applied to various fabrics in the form of spandex core-spun yarn; polyolefin elastic fiber is especially suitable for wool fabrics because it does not require heat setting; two-component polyester composite elastic fiber is used as It can be...
