Embodiment 1）

[0032] The manufacture method of the airgel lightweight warm-keeping fabric of the present embodiment has the following steps:

[0033] S1: Preparation of airgel fibers.

[0034] After the polyester spinning solution is melted, the airgel powder is added to the spinning solution online before spinning to achieve a uniform state; then it is sprayed out through the spinneret hole, and then the fiber is formed, the primary fiber is drawn and oriented, The fibers are heat-set and wound to produce airgel fibers.

[0035] The fineness of the airgel fiber prepared in this example is 75D.

[0036] S2: Weaving the airgel fiber prepared in step S1 as a yarn into a fabric.

[0037] The weft knitting unidirectional machine is used for weaving, and the number of knitting needles matches the denier number of the airgel fiber yarn.

[0038] S3: Dyeing and finishing the fabric obtained by weaving in step S2, the specific method is as follows:

[0039] S31: Soak the woven fabric in the pre...

Abstract

The invention discloses a producing method of an aerogel lightweight heat insulation fabric. The producing method comprises the following steps of S1, preparing aerogel fibers; S2, adopting the aerogel fibers obtained in S1 as yarn, and weaving the yarn into a fabric; S3, conducting dyeing and finishing on the woven fabric obtained in S2; S4, conducting brushing, shearing and anti-pilling on the fabric which is subjected to dyeing and finishing in S3, and obtaining the aerogel lightweight heat insulation fabric. A preparing method of the aerogel fibers in S1 particularly comprises the steps that after a polyester spinning liquid is molten, aerogel powder is added into the spinning liquid online before spinning to achieve a uniform state; then, the mixture is sprayed out of a spinneret orifice, and after fiber forming, nascent fiber draft orientation, fiber thermal shaping and winding, the aerogel fibers are obtained. According to the producing method of the aerogel lightweight heat insulation fabric, the aerogel fibers are prepared by adding the aerogel into polyester and directly serve as the yarn to be made into the fabric; the aerogel lightweight heat insulation fabric is not only high in heat insulation but also light.

Description

technical field [0001] The invention belongs to the technical field of functional textiles, and in particular relates to an airgel lightweight warm-keeping fabric and a manufacturing method thereof. Background technique [0002] my country is the world's largest producer, exporter and consumer of textiles. Textile exports play an important role in my country's foreign trade. With the gradual understanding of functional textiles by consumers in various countries, they have put forward higher requirements for the functionality of textiles. requirements. [0003] With the increasing number of extreme weather in recent years, people put forward higher requirements for the thermal performance of textiles. At the same time, more and more people pursue fashion and love sports, which requires our thermal textiles not to be too heavy and clumsy. . [0004] Among the currently common fiber materials, animal fibers such as cashmere, duck down, goose down, etc. have the best warmth ret...
