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 method for manufacturing an airgel lightweight warm-keeping fabric, which comprises the following steps: S1: preparation of airgel fibers. S2: Weaving the airgel fiber prepared in step S1 as a yarn into a fabric. S3: Dyeing and finishing the fabric obtained in step S2. S4: Brushing, shearing, and shaking the fabric dyed and finished in step S3 to obtain an airgel lightweight thermal fabric. The specific method for preparing the airgel fiber described in the above step S1 is as follows: after the polyester spinning solution is melted, the airgel powder is added to the spinning solution on-line before spinning to achieve a uniform state; The airgel fiber is obtained by spraying out from the hole, and then forming the fiber, drawing and orientation of the primary fiber, heat setting and winding of the fiber. In the present invention, airgel is added to polyester to make airgel fiber, which is directly used as yarn to weave fabric. The fabric not only has high heat retention, but is also relatively 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...
