What Are The Developing Ways Of Thermal Fabric?

< p > at present, the market is warming up < a href= "//www.sjfzxm.com" > fabric > /a > development season. Many enterprises are developing underwear, socks, trousers and coats with warm effect for next autumn and winter.

< p > the raw materials used mainly include moisture absorption and heating fibers, hollow thermal insulation fibers and infrared thermal storage materials. These materials have great differences in use: < /p >

< p > the main principle of hygroscopic heating fiber is to absorb vapor in the gaseous state and turn it into liquid so that its kinetic energy can be pformed into heat energy and make the fabric heat. But when the moisture absorption of the fabric is saturated, the liquid water becomes vaporized and evaporates, and it needs to absorb heat and make the fabric cool.

Therefore, moisture absorption and heating are not the process of heating for a long time.

In the process of dyeing and finishing of concrete spinning, we should pay attention to the damage of phase change materials (microcapsules) which absorb moisture and generate heat, and reduce the temperature, time and frequency of dyeing and finishing as far as possible, otherwise it will damage the phase change materials.

In addition, the moisture absorption and heating fabric is not easy to store for a long time, reduce the number of phase change of moisture absorption and evaporation, and reduce the damage of phase change materials. At present, a href= "//www.sjfzxm.com/news/index_s.asp" > market < /a > the representative hygroscopic and heating fiber is from Japan's EKS, Lina and so on.

< p > infrared thermal storage fiber is mainly used to absorb heat in the environment, light and human body's life hotline to store heat, so as to achieve the purpose of thermal insulation.

Therefore, infrared thermal storage is warm for a long time, and there will be no feeling of cold and hot.

There are two kinds of infrared thermal storage fabrics, which are auxiliaries, finishing and infrared thermal storage fibers. The latter is representative of Mona Lisi, supplied by Shanghai GUI da. Fabric auxiliaries are collated because they are generally not used because of poor durability.

Nanomaterials in infrared thermal storage are better than others because they are added to the melt. They need not worry about loss of function during subsequent dyeing, finishing or even taking.

A high proportion of Mona Lisi and cotton blended for knitting circular knitting machine, 160 grams of fabric, can achieve the detection of thermal insulation index. It is the most thin thermal underwear material in the development process.

< p > the use of hollow fiber on thermal fabric is currently the most representative of THERMOLITE, and also the hollow fiber of Shanghai GUI da. Hollow core fiber can spin high branches and feel softer because of 1.2D.

This type of fiber is mainly made use of the characteristics of air insulation. It is best to use its fluffy properties. The structure of yarns and fabrics should not be too tight. Otherwise, some hollow fibers will be deformed so that they can not reach the purpose of thermal insulation.

As for the tightness of yarns and fabrics, it is necessary to find out the best experience value in many tests, because the density of fabrics will also affect the index of thermal insulation. The fabrics made of hollow fiber are generally lightweight, suitable for < a href= "//www.sjfzxm.com/news/ index_f.asp > coat > /a".
