Preparation method of heat-insulating fabric

Abstract

The invention discloses a heat-insulating fabric, also discloses a preparation method of the fabric, and aims to provide a light, comfortable and warm heat-insulating fabric and a preparation method thereof, belonging to the technical field of spinning. The technical points are as follows: the fabric comprises the following raw materials by mass percent: 33-35% of polyester, 57-61% of viscose fiber and 6-8% of spandex, wherein the polyester and the spandex are blended to serve as the inner layer of the heat-insulating fabric and the viscose fiber and the spandex are blended to serve as the surface layer of the heat-insulating fabric. The preparation method is characterized by alternately arranging a path of viscose fiber and spandex blends and a path of polyester filament yarn and spandexblends to obtain various paths of weft yarns, then adopting a single-side knitting method and different yarn feeding methods for weaving, then carrying out dyeing and finishing and ensuring polyesterto shrink into the inner layer of the fabric and viscose fiber to be on the surface layer of the fabric.

Description

technical field [0001] The invention belongs to the technical field of textiles, and in particular relates to a method for making a thermal insulation fabric. Background technique [0002] With the improvement of people's living standards, people have higher and higher requirements for the comfort and thermal insulation performance of clothing. At present, underwear on the market generally uses ordinary cotton or viscose or fiber blended fabrics, but the oil and moisture produced by human metabolism have been emitting moisture through the epidermis. Cotton fabrics, because the cotton fibers are thinner and have natural curls, and the cross-section has a middle cavity, so they are better in warmth retention. They are more comfortable at first after wearing them, but they will be stickier after a period of human metabolism, especially easier to wear. People who sweat, the moisture produced by the human body is more difficult to volatilize, especially in winter, people feel mo...

Problems solved by technology

Cotton fabrics, because the cotton fibers are thinner and have natural curls, and the cross-section has a middle cavity, so they are better in warmth retention. They are more comfortable at the beginning after wearing them, but they will be stickier after a period of human metabolism, especially easier to wear. People who sweat, the moisture produced by the human body is more difficult to volatilize, especially in winter, people feel more humid and cold, and ordinary cotton is easy to shrink and wrinkle, and the appearance is not very crisp and beautiful

Fiber blended fabrics have the defects of high light spots, which can easily cause dry skin, frictional static electricity, pilling, stuffiness or poor air permeability, poor water absorption, easy spinning when washing, and softness not as good as pure cotton after being made into clothes; Fabric, the advantage of this fabric is that it is cheap, warm and breathable, and lightweight; but chemical fiber friction is prone to static electricity, so a lot of dust and dander will be absorbed inside it after a long time. In addition, the more pores, the rougher the fiber , the worse the fit

[0003] The existing technology adopts double-layer weaving, and also uses different materials for the inner and outer layers, but it is reflected in the fact that the fabric is relatively thick, which is difficult to meet the needs of modern people who like to wear light and thin clothes.
