A kind of cold-proof and warm-keeping fabric and preparation method thereof

Abstract

The invention discloses a cold-proof and warm-keeping fabric structure and a preparation method thereof. The cold-proof and warm-keeping fabric is provided with double fabric base layers (1 and 2) which are connected together in the way that yarns are hooked up and down, so that a double-fabric-base-layer structure with a plurality of cavities (4) which are independent of one another and arrayed longitudinally is formed. Each cavity (4) is internally provided with a tubular nap-proof layer (5). Each tubular nap-proof layer (5) is composed of a nap-proof tube (6), a nap-stopping strip (7) and a nap-stopping head (8). A plurality of nap protrusions (10) are arranged on the surface of each nap-stopping strip (7). The nap-proof tubes (6) and the nap-stopping strips (7) are connected together through nap-proof tube and nap-stopping strip connecting threads (9). The nap-proof tubes (6) and the nap-stopping heads (8) are connected together through nap-proof tube and nap-stopping head connecting threads (12). The nap-proof tubes (6) are filled with down feathers or cotton or woolen products (11). The cold-proof and warm-keeping fabric has good elasticity, high heat retention performance, uniform breathability, close-fitting body shaping performance and machinability.

Description

technical field [0001] The invention relates to a cold-proof and warm-keeping fabric and a preparation method thereof, belonging to the technical field of textile and garment production. Background technique [0002] Among the currently commercially available cold-proof and warm-keeping fabrics, down products have the best cold-proof and warm-keeping effect. On the market, a simple single-layer fabric is generally used to directly wrap the down and sew it into a sheet. Although it has warmth retention properties, the fabric has a large amount of down and lacks elasticity overall. Daily free activities also lack aesthetic sense; and because the down-proof layer is filled with down in a large area, the down is very uneven; when people are afraid of the cold in winter, they generally choose to wear down jackets, such as wearing down jackets to enter warm places or do a lot of exercise. When the human body is prone to sweating, people in northern my country have heating in their ...

Problems solved by technology

However, this patented technology only adopts the fabric base layer on one side, and one side of the tubular fleece-proof layer causes the fabric to be bubbly, uneven, and affects the next step of mechanical operation, so it is difficult to realize mechanical mass production; moreover, the single fabric base layer There are a large number of sewn tube-shaped anti-down tubes on the track, which also greatly affects the elasticity and overall smoothness of the base layer; there are also exposed down-proof tubes that have not been blocked by any method, and there is also a large area of ​​velvet leakage at the seam, and the actual A lining fabric layer must be added when using it, otherwise the irregularly exposed down-proof tube layer cannot be used in the consumer terminal
