Problems solved by technology

Generally, the thicker the material, the lower the density, and the better the thermal insulation of the material. However, if the density of the material is too small, when the air in it is convected, the thermal insulation performance will decrease instead. For thermal insulation materials for clothing, the thickness is too large. The volume of clothing is relatively bloated, it is not convenient for sports and lacks aesthetic feeling. With people's pursuit of beauty, this method of increasing the warmth of clothing by increasing the thickness of the material cannot meet people's requirements for clothing functionality and aesthetics.

Abstract

The invention relates to a glued and flocked high-elasticity thermal flaky material and a production method for the same, and belongs to the technical field of textiles. The opposite surfaces of an upper-layer fiber web and a lower-layer fiber web of the high-elasticity thermal flaky material are coated with an upper adhesive film and a lower adhesive film respectively, piles are sandwiched between the upper-layer fiber web and the lower-layer fiber wed, and the two ends of the piles are inserted into the upper and lower adhesive films respectively, and are fixedly adhered to the surfaces of the upper-layer fiber web and the lower-layer fiber web. The preparation method comprises the following steps of (1) fiber web preparation, (2) gluing, (3) electrostatic flocking, (4) drying, (5) pile suction, (6) fiber wed compounding, (7) drying and (8) winding. Compared with the prior art, the produced thermal flaky material has the advantages of high elasticity and high heat retention performance.

Description

technical field [0001] The invention relates to a glue-coated flocking type high-elastic heat-retaining sheet material and a manufacturing method thereof, belonging to the field of textiles. Background technique [0002] With the development of the chemical fiber industry, the research and development of thermal insulation materials have shifted from natural fibers such as fur, silk, wool, cotton and down to chemical fibers, and chemical fiber thermal insulation sheets mainly composed of polyester, polypropylene fiber and acrylic fibers have appeared, such as spray Collodion cotton, acupuncture cotton, space cotton, hot-melt cotton, melt-blown far-infrared cotton, ultra-fine hot-melt cotton, imitation down cotton and other thermal products. Thermal insulation materials made of cotton, hemp, silk, wool and ordinary polyester, nylon, acrylic fiber and man-made fibers are generally called traditional thermal insulation materials. Among these thermal insulation materials, silk a...
