Design method and production process of a kind of multi-layer thermal fabric

Abstract

The invention discloses a design method and a production process of a multi-layer thermal insulation fabric. The surface fabric of the present invention adopts polyimide fiber and hollow polyester fiber blended Siro compact spinning, and the fabric has high strength, good friction resistance and warmth retention. The warp yarn of the middle layer fabric of the present invention adopts cotton and hollow polyester fiber blended yarn, and the weft yarn adopts OUTLAST phase change fiber and coffee carbon polyester fiber blended yarn, and the longer floating length of the weft yarn is used in the middle of the two layers of fabrics, and the yarn is in the middle of the fabric. In the fluffy state, it supports the outer and inner layers of fabric to form a thermal insulation layer. Because the middle layer has thicker yarns, a smaller twist coefficient, and the use of heat-absorbing thermal fibers, it is beneficial to provide the thermal insulation performance of the fabric. The inner layer of the present invention adopts the blended yarn of cotton and hollow polyester fiber, which has good heat-retaining effect, good skin-friendly property, moisture absorption and breathability, and avoids discomfort caused by fabric moisture absorption and sticking to the body after sweating due to excessive moisture regain.

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
