Design method and production technology of multi-layer heat preserving shell fabric

Abstract

The invention discloses a design method and a production technology of a multi-layer heat preserving shell fabric. The design method is characterized in that a woven fabric on the surface layer is prepared by blending polyimide fiber and hollow polyester fiber with compact sirospun yarn; the shell fabric is high in strength, high in friction resistance and high in heat preserving performance; warpyarn of the woven fabric on the intermediate layer is cotton and hollow polyester fiber blended yarn; weft yarn is OUTLAS phase-changed fiber and coffee carbon polyester fiber blended yarn; a relatively long floating line of the weft yarn is positioned between the woven fabrics on the surface layer and the inner layer, so that the yarn is in a loose state and supports the woven fabrics on the surface layer and the inner layer, and as a result, a heat preserving layer is formed; the yarn in the intermediate layer is relatively thick, the twisting coefficient is small, and heat absorbing and preserving fibers are adopted, so that the heat preserving performance of the woven fabrics can be ensured. The inner layer is the cotton and hollow polyester fiber blended yarn, so that the heat preserving effect is good; the shell fabric is skin friendly, can absorb moisture and is breathable, so that the problem of discomfort caused by that a woven fabric with too high moisture regain absorbs moisture and adheres to the body can be avoided.

Description

technical field [0001] The invention specifically relates to a design method and a production process of a multi-layer thermal fabric. Background technique [0002] The most important function of clothing is to maintain the normal temperature of the human body and make the human body feel comfortable. With the fashion of clothing, it is not only cumbersome but also sometimes difficult to maintain a suitable temperature for the human body only by increasing or decreasing the thickness of the fabric. At the same time, due to climate change in recent years, the number of cold days in winter has gradually increased, and extreme cold weather has appeared in many places. How to wear fashion and keep warm in the cold winter and make warm clothing lighter and thinner has become consumers' demands for winter clothing fabrics. With people's increasing requirements for high-grade clothing and functional finishing fabrics, the development of new thermal fabrics will have a good develop...

AI Technical Summary

Problems solved by technology

[0003] Traditional thermal clothing such as down jackets mainly increase the thickness of the fabric to increase the space of the still air layer of the fabric to improve the thermal effect, and the clothing is bloated and single

New thermal insulation fabrics usually adopt methods such as vapor-depositing metal on the surface of the fabric, composite metal layers, etc., using the specular reflection properties of metals to inhibit the heat radiation from the human body, such as Columbia's OMNI-HEAT heat reflection technology, but there are strong heat conduction, lack of coloring, Disadvantages such as poor air permeability and moisture permeability, and inability to wash

At present, the thermal underwear in the best-selling market belongs to the hygroscopic heating fiber. When the fiber absorbs water, the hydrophilic group in the fiber molecule combines with the water molecule, and releases heat when the water liquefies, but the heating effect is limited, and the warmth retention effect is average. The thread is mostly made of chemical fiber blend, which is not as comfortable as cellulose fiber, so it is not suitable for people with skin allergies to wear next to the body
