Abstract

The invention relates to the technical field of differential chemical fiber, and provides a cool quick-drying hydrophilic polyester fiber and a processing method thereof, which aims at solving the problem of poor moisture absorbing property and poor heat absorbing property in the existing polyester fiber with cool characteristic. The cool quick-drying hydrophilic polyester fiber has the advantages that the cross section is in a cross shape; the break strength is 2.8 to 4.0cN / dtex, and the elongation at break is 18 to 30%; jade powder and perlite powder are contained; the moisture absorbing property is good, the water and steam conveying property is excellent, the heat can be quickly conducted and absorbed, the anti-ultraviolet property is realized, and the trace element and amino acid are contained.

Description

technical field [0001] The invention relates to the technical field of differential chemical fibers, in particular to an ice-cooling quick-drying hydrophilic polyester fiber and a processing method thereof. Background technique [0002] Cool textile fibers have always been a research direction for chemical fiber workers. At first, the breathability and quick-drying of the fibers were achieved by changing the cross-section of the fibers. Later, in order to improve the hydrophilicity of polyester, many researchers added a third , The fourth monomer to develop hydrophilic modified polyester. In recent years, the thermal conductivity of polyester has been enhanced by adding mica and jade powder to polyester to improve the cooling properties of polyester fiber. With the change of consumption concept, people's requirements for summer clothing are not only stylish, but also pay more attention to the inner coolness and comfort of clothing. Conventional polyester (PET) fiber is the...
