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 polyester yarn with the high wet permeability and a manufacturing method thereof. The polyester yarn is prepared by blending of polyester fiber with a line-shaped section and polyester fiber with a cross-shaped section. The manufacturing method comprises the steps that firstly, according to the ratio of the number of the fibers, the polyester fiber with the line-shaped section and the polyester fiber with the cross-shaped section are selected; secondly, the polyester yarn is obtained after doubling and blending. According to the prepared polyester yarn, the number of capillary pores and the porosity are greatly increased, the wicking effect is obviously improved, the wet permeability is obviously improved, and the polyester yarn can be used individually or blended with other fiber yarns so as to be weaved into a high-wet-permeability fabric, and can be widely used in the fields of clothing, decoration and industries.

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...
