The concept of "energy saving shirt" comes from the "cool business" campaign launched by the Japanese government in 2005.

It calls on male business people to increase their office air conditioning temperature and reduce carbon dioxide emissions without wearing ties or wearing suits in summer.

The idea of saving electricity by wearing less clothes brings innovation and inspiration to the global textile industry. Therefore, high heat dissipation, low specific heat and high moisture absorption cool fibers emerge as the times require.

The cool fiber WinCool products developed by Huayuan Textile in Fuyang are woven into the fiber through the composite ore powder which is good at heat conduction and heat dissipation, so that the cool and slippery feeling can be pferred to the skin through the yarn, so that the clothing has instant coolness. The profiled section structure makes the fibers appear cross section with concave and convex shape, so as to set up "drains" for human beings, imitate the capillary sweat absorption effect, make the fabrics absorb the sweat and moisture quickly on the skin surface, and spread to the fabric surface and evaporate, so that the clothes are instantly dry and have great comfort.

In terms of energy efficiency, the textile experts tested that at the same temperature, the temperature of people wearing cool clothes and fibers during exercise was 1.27 degrees lower than that of ordinary absorbent fibers, and the relative humidity decreased by 20%.

This means that wearing the "energy-saving shirt" made of cool fiber can not only reduce the original comfort of the human body, but also increase the air conditioning temperature by 1 degrees ~2 C, which can save electricity by 6%~10%, which can effectively reduce carbon dioxide emissions and meet the requirements of low carbon economy.

At present, Fuyang Huayuan Textile Co., Ltd. has developed a series of woven yarn and knitted yarn blended with WinCool cool fiber and Tencel, wool, Coolday, cotton, polyester, acrylic fiber and other raw materials. It not only embodies the advantages of cool fiber but also reduces the cost. It can be used in shirts, underwear, sportswear, bedding and beauty products such as facial mask, wet towel and other fields, and has a good application prospect.
