Abstract

The invention discloses a high-shape-preserving comfortable health-care fabric and a preparation method thereof. In the preparation of the fabric, 60% of polyester parallel composite fibers, 30% of cotton fibers and 10% of aloe fibers are blended to serve as warp yarns, regenerated polyester fibers prepared by spinning and forming at least one of cloth, bottle flakes and foam materials serve as weft yarns, and the fabric is prepared through the procedures of warp weaving, weaving and the like. The polyester parallel composite fibers are prepared in a way that PET with different viscosities is subjected to melt extrusion by a screw rod, metering by a metering pump and composite molding by a spinneret plate according to a ratio of 1: 1, and finally is subjected to extension processing and heat treatment; the sections of the obtained polyester parallel composite fibers are splayed, so that the elasticity and resilience of the polyester parallel composite fibers are enhanced, and the high-shape-preserving comfortable health-care fabric has the advantages of high elasticity and shape preservation; and meanwhile, the added cotton fibers and aloe fibers enable the fabric to have the advantages of good moisture absorption, breathability, health-care function and environmental protection property.

Description

technical field [0001] The invention relates to a high-shape, comfortable and health-care fabric and a preparation method thereof, belonging to the technical field of textile manufacturing. Background technique [0002] With the continuous development of the economy and the continuous improvement of material living standards, people's concept of clothing has also changed, and the awareness of health care has continued to increase. Traditional classic high-end worsted fabrics no longer meet people's needs. Therefore, various textiles and The requirements for health care, comfort and warmth of clothing materials are also constantly improving. Health care performance and environmental protection performance are important functional indicators of textile fabrics, and shape retention is an important quality indicator of textile fabrics. It is well known that although natural fiber fabrics have the advantages of comfort, hygiene, environmental protection and certain health care pr...
