Xing Zhigui, secretary-general of the Knitwear Branch of the National Textile Standardization Technical Committee, said that the moisture-absorbing thermal underwear is not a thermal underwear, and the mechanism of moisture absorption and heat retention is different. Specifically, the moisture absorption and heat is underwear, which has the effect of moisture absorption and active heat generation, while the warmth is heat insulation, and the underwear can control the heat loss of the human body by reducing the gas permeability, that is, the heat energy is not generated by the underwear.
The advantage of the heating underwear is that it can heat itself and the fabric is light and thin; the disadvantage is that if the warmth is not good, the heat generated may be quickly lost. The advantage of thermal underwear is to prevent the body from losing heat and keep warm for a long time; the disadvantage is poor ventilation.
According to the relevant regulations of the industry standard “moisture-absorbing and heating knitted underwear†that has been implemented in China, the hygroscopic heating underwear should be prepared from hygroscopic heating materials and meet two heating value indicators: the highest heating value is not lower than 4 ° C; the average within 30 minutes The temperature rise value is not lower than 3 °C.
Zhang Yi, a professor at the Textile Institute of Tianjin Polytechnic University, said that no matter what fabrics or materials are used, thermal insulation underwear should meet the requirements of the national textile industry standards, that is, the insulation rate is not less than 30%, and the thermal underwear can only meet the industry standard of hygroscopic products at the same time. The heat preservation rate standard can achieve the effect of both heat and warmth.
Wang Zhi, honorary chairman of the China Knitting Industry Association and deputy director of the underwear professional committee of the China Garment Association, said that at present, the common hot underwear in the market is basically warmed by the principle of moisture absorption and heat. The hygroscopic heat-absorbing fiber is released by absorbing the moisture emitted by the human body and converting the moisture into heat. However, because the fiber material is expensive, the heat-generating underwear is mostly made of a small amount of heat-generating fiber combined with other fibers, and generally, it can only take the initiative. The temperature rises from 2 ° C to 4 ° C, so it cannot be achieved by the requirements of the cold.
