Description

Technical Field

[0001] The utility model relates to a semi-dull polyester low-elastic composite yarn, belonging to the technical field of composite yarns. Background Art

[0002] Polyester fiber has a series of excellent properties such as high breaking strength and elastic modulus, moderate resilience, excellent heat setting, good heat and light resistance, acid and alkali resistance, corrosion resistance, etc., and the fabric has the advantages of wrinkle resistance, ironing-free and good stiffness, so polyester fiber is widely used in clothing, home textiles and other fields. With the continuous improvement of social material level, people have higher and higher requirements for sports, leisure, fashion, comfort and health fabrics. Stimulated by huge market benefits, various manufacturers have begun to develop highly sensitive and highly functional polyester fiber products. The industry has developed differential fibers such as matte, semi-matte, moisture absorption and perspiration, antibacterial, mosquito-proof, colored and flame-retardant, providing new high-quality fiber raw materials for textile fabrics and home textiles. Because polyester has a smooth surface and a certain degree of transparency, the intensity of its reflected light is very high under the irradiation of light, making the fiber emit a strong luster that looks uncomfortable to the naked eye, commonly known as aurora.

[0003] Existing semi-dull polyester usually adds a matting agent during the polyester melt spinning process, so that the polyester fiber diffusely reflects light, thereby reducing the intensity of the reflected light. However, the existing semi-dull polyester has a relatively single functionality, and how to prepare a semi-dull polyester low-elastic composite yarn has become a problem to be solved.

[0005] In order to solve the above technical problems, the purpose of the utility model is achieved as follows:

[0006] The utility model relates to a semi-dull polyester low-elastic composite yarn, comprising a core yarn and a covering yarn; the core yarn is a polyester low-elastic yarn and an antibacterial polyester yarn twisted in parallel; the covering yarn comprises a semi-dull nylon 6FDY filament and a special-section nylon 6POY filament; the semi-dull nylon 6FDY filament and the special-section nylon 6POY filament are covered on the outside of the core yarn in opposite winding directions.

[0007] On the basis of the above scheme and as a preferred scheme of the above scheme: the cross section of the special-shaped cross-section nylon 6POY is Y-shaped, cross-shaped, double cross-shaped or five-leaf-shaped.

[0008] On the basis of the above scheme and as a preferred scheme of the above scheme: the antibacterial polyester yarn is a nano zinc oxide in-situ modified polyester yarn.
