Problems solved by technology

However, in this modification method, the grooves on the fiber surface are easily filled by the fiber blades, thereby reducing the number of effective capillary pores between the fibers and reducing the moisture conductivity of the fiber yarn, especially after the fiber yarn is twisted and woven. worse
Therefore, this modification method has limitations in improving the moisture permeability of fibers.

Abstract

The invention relates to a terylene yarn with high moisture-transmitting property and a production method thereof. The terylene yarn is made by blended spinning of a straight-line section terylene fiber and a cruciform section terylene fiber. The production steps include (1) the straight-line section terylene fiber and the cruciform section terylene fiber are selected based on the ratio of fiber number; (2) the terylene yarn is produced after treatment of fiber strand and mixing. Number of inner capillary porosity and capillary wicking of the produced terylene are greatly increased and the moisture-transmitting property is obviously improved. The terylene yarn can be used for producing high moisture-transmitting fabric textile separately or together with other fiber yarn, thereby being widely applicable to fields of cloths, decoration and industry.

Description

technical field [0001] The invention belongs to polyester yarn and a manufacturing method thereof, in particular to a polyester yarn with high moisture permeability and a preparation method thereof. Background technique [0002] With the development of the economy and the progress of the society, people's quality of life is getting higher and higher, and the requirements for the comfort performance of clothing are also getting higher and higher. Natural fiber (such as cotton fiber) fabrics have good hygroscopicity, but their moisture permeability and quick drying are poor, and moisture sticks after absorbing sweat, while synthetic fiber (such as polyester) fabrics are crisp and easy to clean, but their moisture absorption and moisture permeability are poor. . In recent years, a class of high moisture permeability fibers and their fabrics obtained by modifying synthetic fibers have rapidly become the focus of the market. [0003] The modification methods of high moisture pe...
