Problems solved by technology

The distribution of sweat on the surface of the human body is not uniform, and the heat generation power of the moisture-absorbing and heating fabric comes from the adsorption of water molecules. Therefore, the uneven temperature change caused by the uneven moisture absorption of the fabric in a unit time will make the human body feel thermal discomfort and dampness. Discomfort is not conducive to the human body's own requirements for thermal and wet comfort of clothing

Embodiment 1

[0060] A kind of moisture-absorbing and heat-generating fabric, which is woven by four kinds of yarns. The outer yarn is a moisture-absorbing and heat-generating yarn blended with soothing silk fiber and viscose fiber at a blending ratio of 20 / 80. The yarn count is 32S, of which the comfortable Hot filament fiber is developed by Shanghai Jieyikang Chemical Technology Co., Ltd. It is a kind of acrylic fiber made by special process, which is composed of acrylic acid, sodium acrylate and acrylamide. The weft insertion yarn is 32S cotton carded yarn; the connecting yarn is 75D / 72F polyester DTY filament; the inner layer yarn is 75D / 72F cross-section COOLDRY polyester filament and 60S polyester / cotton blending ratio is 80 / Composite yarn made of 20 spun yarns.

[0061] The weaving method of the moisture-absorbing uniform and slow-heating fabric comprises the following steps in turn:

[0062] (1) Select the above-mentioned four kinds of yarn raw materials according to the designed ...

Embodiment 2

[0073] A moisture-absorbing fabric with even and slow heating, woven from four kinds of yarns, the outer yarn, weft-insertion yarn, and connecting yarn are the same as in Example 1, and the inner yarn is 75D / 72F cross-section COOLDRY polyester Composite yarn made of filament and 60S pure cotton staple yarn.

[0074] The weaving method of the moisture-absorbing uniform and slow-heating fabric comprises the following steps in turn:

[0075] (1) Select the above-mentioned four kinds of yarn raw materials according to the designed fabric, and prepare the necessary number of raw material tubes for the above four kinds of raw materials when going on the machine according to the actual situation of the model;

[0076] (2) The raw material is weaved on the machine. When weaving on the machine, it is the same as the method of embodiment 1, except that the ① and ⑤ roads are 75D / 72F cross-section COOLDRY polyester filament and 60S pure cotton spun yarn Composite yarn formed by doubling;...

Abstract

The invention relates to moisture-absorption uniform and slow heat fabric and a weaving method thereof. The moisture-absorption uniform and slow heat fabric is moisture-absorption uniform and slow heat fabric with a three-layer structure woven by adopting a knitting, weaving, non-woven technology or a multilayer sewing technology, and the three-layer structure is composed of an inner layer, a middle layer and an outer layer, wherein the inner layer has diffusion and moisture conduction functions, the middle layer has moisture absorption and storage functions, and the moisture absorption capacity and the liquid moisture diffusion speed of the middle layer are both between the inner layer and the outer layer; and the outer layer has moisture absorption and heating functions. The temperaturerise rate of the woven moisture-absorption uniform and slow heat fabric to reach a highest temperature rise value is less than 1 DEG C/min, the time for the fabric to reach the highest temperature rise value is delayed by 1-3 min compared with weft planin-knitted fabric woven by similar moisture-absorption heat blended yarn, and the heat-retaining time of the fabric is 21-25 min; and under the same humidification condition, the heat area of the moisture-absorption uniform and slow heat fabric is 5% or above more than the heat area of the weft planin-knitted fabric woven by the similar moisture-absorption heat blended yarn.

Description

technical field [0001] The invention belongs to the technical field of weaving, and relates to a moisture-absorbing, uniformly slow-heating fabric and a weaving method thereof. Background technique [0002] With the development of science and technology and the improvement of living standards, people's requirements for the practical functions of fabrics and clothing tend to be diversified. As a positive heat-generating material different from traditional heat insulation materials, heating materials have become more and more popular. It has received people's attention and love, and it can meet the multiple requirements of people's winter clothing for comfort, functionality and aesthetics. According to the test data, when a person is exercising, a lot of sweat is discharged, both in liquid state and in gaseous state, and the amount is about 100g / m 2 h, while the water evaporates outward through the skin at rest is about 15g / m 2 h; Therefore, the human body produces a large a...
