Problems solved by technology

Among them, phase-change materials have the best thermal insulation effect, mainly through the transformation of three states, but the cost is relatively high, and the consumer market is relatively limited; there are many far-infrared and hollow fabrics on the market, but the effect is not good. ; Coated film fabrics have obvious thermal insulation effect, but because too many aromatic ester chemicals are involved in the processing of this product, there are certain problems in terms of environmental protection

Embodiment 1

[0017] Use 56T-24-SDY polypropylene fully drawn yarn as the core yarn and 44T-34-FDY polyamide fully drawn yarn as the sheath yarn. The polyamide part accounts for 46.2% (weight percentage), and the polypropylene part accounts for 53.8% (weight Percentage), processed into composite wire (core and sheath wire feeding difference is 10%, using Taslan nozzle, processing pressure 0.8Mpa). The composite yarn has a fineness of 91 denier, a breaking strength of about 3.5 cN / dtex, a breaking elongation of 55%, a boiling water shrinkage rate of 4.5%, and the number of 0 mm-0.4 mm coils distributed between 9800 and 13000 / 2000 Between meters.

[0018] The composite yarn prepared above is used as the weft yarn, and 70-24f-SD.NY is used as the warp yarn. It is woven with a 1 / 1 plain weave, and the warp and weft density of the grey fabric is 114 pieces / inch×70 pieces / inch. The grey fabric is finished by refining → intermediate setting → dyeing → drying → resin → finishing and setting.

Embodiment 2

[0025] Use 83T-36-FDY polypropylene full-drawn wire as the core wire, 83T-72-FDY polyamide full-drawn wire as the sheath wire. The polyamide part accounts for 57.6% (weight percentage), and the polypropylene part accounts for 42.4% (weight Percentage), processed into composite yarn (core and sheath yarn feed difference is 9.3%, using Taslan nozzle, processing pressure is 0.8Mpa), composite yarn size is 150 denier, breaking strength is about 3.5 cN / dtex, The elongation at break is 53%, the shrinkage in boiling water is 4.8%, and the number of coils of 0 mm-0.4 mm is distributed between 9800-11000 / 2000 meters.

[0026] Use the above-mentioned composite processed silk as warp and weft, and adopt composite twill weave , The warp and weft density is: 106 strands / inch×120 strands / inch. After sizing, warping, weaving and other processes, the grey fabric is made, and then the grey fabric is refined → pre-shaped → dyed → resin → finishing setting → coating to make the product.

Embodiment 3

[0033] Use 56T-24-SDY polypropylene fully drawn yarn as the core yarn and 44T-34-FDY polyamide fully drawn yarn as the sheath yarn. The polyamide part accounts for 46.81% (weight percentage), and the polypropylene part accounts for 53.19% (weight Percentage), processed into composite wire (core and sheath wire feeding difference is 12%, using Taslan nozzle, processing pressure 0.8Mpa). The composite yarn has a fineness of 95 denier, a breaking strength of about 3.6 cN / dtex, a breaking elongation of 55%, a boiling water shrinkage rate of 4.3%, and the number of 0 mm-0.4 mm coils distributed between 9800 and 13100 / 2000 Between meters.

[0034] The composite yarn prepared above is used as the weft yarn, and 70-24f-SD.NY is used as the warp yarn. It is woven with 2 / 2 warp heavy flat structure, and the density of the warp and weft of the grey fabric is 114 strands / inch×68 strands / inch. After sizing, warping, weaving, etc., the grey cloth is made into a grey cloth, and then the grey clo...

Abstract

The invention discloses a fabric with lightweight heat-preserving function and a production method thereof; at least one of the warp yarn or weft yarn constituting the fabric is composite processing silk which is composed of polyamide fiber and polypropylene fiber, wherein the polyamide fiber accounts for 45 percent to 75 percent of the composite processing silk and the polypropylene fiber accounts for 25 percent to 55 percent of the composite processing silk; the fabric is weaved with plain weave, twill weave, and complex changing tissue; and the surface of the manufactured fabric has a certain heterochromatic nature, takes on special floral effect and has good dimensional stability and super-imitated cotton and wool-like feel. After the process of coating or film laminating is carried out, the performances of water-proof and heat-preservation become better.

Description

Technical field [0001] The invention relates to a lightweight warmth-keeping textile and a production method thereof. Background technique [0002] The thermal insulation fabrics currently on the market mainly include hollow thermal fabrics, far-infrared thermal fabrics, coating films, and phase change materials. Among them, phase change materials have the best thermal insulation effect, mainly through the three-state transformation, but the cost is relatively high, and the consumer market is relatively limited; there are many far-infrared and hollow fabrics in the market, but the effect is not good ; The coating film fabric has an obvious warmth retention effect, but because there are too many aromatic ester chemicals involved in the processing of this product, there are certain problems in environmental protection. Summary of the invention [0003] The purpose of the present invention is to provide a light-weight and warm-keeping fabric with a flowery surface and a light-weigh...
