Abstract

The invention relates to a thin film flocked-type high-elastic flame-retarding warm-keeping sheet material and a preparation method thereof and belongs to the technical field of textile. In the interiors of an upper fiber net layer and a lower fiber net layer of the sheet material, a mixed powder composed of a hot melting powder and a flame retarding powder is filled. An upper flocked thin film base material and a lower flocked thin film base material are fixedly combined respectively with the two opposite surfaces of the upper fiber net layer and the lower fiber net layer, wherein fluffs are fixed combined between the upper flocked thin film base material and the lower flocked thin film base material. The preparation method includes following steps: (1) preparation before flocking; (2) preparation of the fiber nets; (3) powder preparation; (4) powder filling; (5) drying; (6) hot-pressing film coverage; (7) glue coating; (8) electrostatic flocking; (9) drying; (10) fluff suction; (11) composition of the fiber nets; (12) drying; and (13) winding. Compared with a sheet material in the prior art, the warm-keeping sheet material is excellent in flame retarding function, is good in elasticity and is good in warm keeping performance.

Description

technical field [0001] The invention relates to a thin-film flocking type high-elastic flame-retardant heat-retaining sheet material and a manufacturing method thereof, belonging to the field of textiles. Background technique [0002] In the past, people used traditional thermal insulation materials made of cotton, hemp, silk, wool and ordinary polyester, nylon, acrylic fiber and man-made fibers as thermal insulation materials. Among these thermal insulation materials, silk and wool have better thermal insulation properties. However, the fiber is prone to bacteria and is not resistant to moths. Moreover, silk is expensive, wool fiber has peculiar smell and poor molding degree, and cashmere processed through multiple processes is more expensive, and its use has been limited for many years. With the development of living standards and science and technology, people began to develop new thermal insulation materials, and chemical fiber thermal insulation sheets mainly composed o...
