Abstract

The invention relates to the technical field of textile fabrics, and particularly discloses a thin warm type aerogel textile fiber fabric and a preparation method thereof. The product comprises the following components in percentage by weight of 10%-90% of aerogel modified fiber and the balance of cashmere fiber or wool fiber or cotton fiber, wherein the aerogel modified fiber comprises the aerogel and matrix fibers in a mass ratio of 1: (10-300), the aerogel is silicon dioxide aerogel, and the matrix fibers are any one of polyester fibers, polyamide fibers, polyacrylonitrile fibers and polypropylene fibers; and the preparation method comprises the following steps of S1, cutting modified polyester into particles; S2, fusing and spinning; and S3, weaving the fabric. The thin warm type aerogel textile fiber fabric has the advantages of being light, thin and good in warmth retention property.

Description

technical field [0001] The invention relates to the technical field of textile fabrics, more specifically, it relates to a thin warm airgel textile fiber fabric and a preparation method thereof. Background technique [0002] Airgel is a low-density, high-porosity nanoporous material first developed by American scientist S. Kistier in 1931. In 1993, NASA applied airgel as thermal insulation material to the aerospace field. More than 90% of the airgel is a static air mass of 10-30 nanometers, which has a very good heat insulation effect. An inch-thick airgel The heat insulation effect is equivalent to that of 20-30 pieces of ordinary glass. [0003] Although some attempts have been made to apply airgel to the textile field, at present, airgel is more commonly used in the post-dyeing and finishing processes of fabrics such as textile fabric coating and dyeing and finishing reagent addition, and airgel is directly applied There are few reports on textile fibers and weaving fab...
