New Trend Of Thermal Fiber: Intelligent Temperature Regulation

< p > air conditioning has been put into practice by fiber enterprises, and the way to achieve it is to develop and produce "intelligent" fibers that can adjust temperature.

< /p >

< p > this kind of "intelligent" fiber, known as "warm fiber", combines the specialized knowledge of physics and chemistry, combines the characteristics of textile materials, and crossover disciplines, and crossover innovation.

The success and wide application of materials improve the quality of life of the public, and indirectly save energy consumption in automatic temperature regulation. They belong to environmental protection materials and adapt to the current trend of development.

For example, people dressed in it can properly adjust the temperature of the air conditioning in a hot summer without appearing to be hot.

Scientific and technological materials help people better realize their own value orientation, so that individuals unknowingly join the ranks of energy conservation and consumption reduction.

This is the environmental contribution of thermal fiber.

< /p >

< p > of course, warm fiber can bring warmth in the cold outdoor.

Lighter fabric can bring better cold protection effect and will be more comfortable for outdoor fans.

The thicker it is, the warmer it is, and the truth is that it is no longer true. While the thermal fiber helps consumers understand that clothing is warm and comfortable, fiber companies can do better.

< p > research shows that when the body is in a thermal equilibrium, the average temperature of the comfortable skin is about 33.4 degrees Celsius. The difference between the skin temperature and the average skin temperature of any part of the body is between 1.5 and 3 degrees Celsius. The human body feels cold and warm, exceeding the range of + 4.5 degrees Celsius, and the body will have a sense of warmth and warmth.

The temperature regulating fiber is a kind of two-way temperature adjusting and heat preservation material.

It has an endothermic function at higher ambient temperatures and has an exothermic function at lower ambient temperatures.

It fundamentally extends the original function of fiber and belongs to the new "intelligent" fiber.

< /p >

< p > according to its regulation mechanism, the thermal fiber can be divided into four types: medium phase change temperature regulating fiber, medium dissolution and precipitation tempering fiber, tempering and humidity regulating fiber and particle temperature regulating fiber.

Most of the products in the market are medium phase change thermostat materials (also known as thermal storage thermoregulation materials).

< /p >

< p > the so-called phase pition refers to the pformation of material from one phase to another, which absorbs heat or releases heat, and the phase pition occurs at a constant temperature.

By adding a certain medium in the fiber (considering its phase pition temperature is within a certain range), the phase change characteristics of the medium are used to ensure that the fiber temperature remains unchanged when absorbing or emitting heat.

For example, phase change energy storage viscose fiber is the advanced material under this theory.

Its emergence for the first time changed the traditional passive defense heating mode to the active thermostat mode, and most importantly, it did not consume other energy sources and adapted to the current energy crisis. It was chosen by the US Newsday as "one of the 21 innovations to change human life in twenty-first Century". It is the most important comfort textiles in the 20 years since the waterproof and moisture permeable fabric.

Heng Tian Hai Long Limited by Share Ltd and Tianjin University of Technology have developed high-tech products with the function of regenerative and exothermic two-way temperature regulation, which are developed by Microsoft capsule technology and Tianjin University of Technology. The products developed are "high temperature resistant microencapsulated phase change materials and high heat storage heat storage and tempering fibers", which won the two prize of national scientific and technological invention in 2010.

The processing technology of < p > a href= "http://www.91se91.com/news/index_c.asp" > warm fiber < /a > is also quite characteristic, and the concept of masterbatch is introduced.

Through the pre spinning injection, the phase change material microcapsule, far-infrared powder and other heating materials and viscose or acrylic fiber raw materials are mixed, and the heat storage acrylic fiber and viscose heat preservation fiber are prepared by adopting the low acid coagulation bath's relaxation molding and low temperature post-processing technology.

The regenerated acrylic fiber developed by Jilin chemical fiber adds natural mineral materials to the regenerative fibers. When sunlight or other heat sources are irradiated, the heat energy in the heat source can be absorbed and stored to the maximum extent. It has good health functions of heat storage, warmth retention and far-infrared rays, and meets the requirements of people for the beauty and comfort of fabrics.

< /p >

< p > in the mentioned phase change energy storage fibers, the most developed phase change energy storage viscose fiber is best developed.

Phase change energy storage viscose fiber, commonly known as air conditioning fiber, is a high-tech product developed by the most advanced microcapsule technology, which has the functions of heat storage and heat release.

According to Silver Eagle chemical fiber company, they successfully developed phase change energy storage viscose fiber, its dry cracking strength is more than 1.82cN/dtex, the moisture splitting strength is more than 0.84cN/dtex, the dry elongation is more than 16%, and the fiber heat storage reaches more than 10J/g.

The heat preservation function and the high spinnability are all in one phase, and the phase change energy storage viscose fiber becomes a new value in textile materials.

< /p >

< p > the types of thermal fiber are far more than those introduced, such as coffee carbon fiber.

For example, the blended yarn or fabric of several fibers has increased the effect of keeping warm.

At the beginning of this year, the new products of "coffee carbon fiber / tussah spun yarn / acrylic yarn multi component thermal fabric" jointly undertaken by Nantong home textile design and technology service center of Nantong Textile Vocational Technology College and Liaoning Tussah Silk Research Institute were identified in Jiangsu Nantong. The expert group considered the product to be the first in China and the technology and technology in the domestic advanced level.

< p > heat storage and heat preservation fiber can produce heat insulation. It is suitable for making all kinds of warm clothing, health care underwear, health socks, health care protective clothing, bedding, mattress, blanket, functional health products, etc. it is suitable for knitting and weaving all kinds of products. The products can be used alone or interwoven with various fibers, so that the content in the fabric is more than 30% in order to ensure its performance.

Through blending technology, the thermal fiber is blended with other fibers, and the distribution of warmth fibers in the yarn is designed, and the effectiveness of the thermal fiber is fully and efficiently played.

< /p >

< p > for example, the heat storage and tempering fiber produced by Limited by Share Ltd is pure spinning, and can be blended with cotton, wool, silk, hemp and other kinds of fibers, woven and knitted.

Its fabric is round, smooth, Hikaruzawa Ryorei, skin friendly, and has good breathability and dehumidification properties. The costumes made in this product are popular in many countries and regions such as Europe, America and Japan, especially in outdoor sports and elderly people and infants who are more sensitive to temperature changes.
