Color-changing yarn Reversible thermochromic yarn itself is an unstable system (it is difficult to change when stable), so its light resistance, heat resistance, aging resistance and other properties are far less than ordinary yarns, so attention should be paid in use. Lightfastness: Thermochromic yarns have poor lightfastness and will quickly fade and fail when exposed to strong sunlight, so they are only suitable for indoor use. The exposure to strong sunlight and ultraviolet light should be avoided, which is beneficial to prolong the service life of the color-changing yarn. By. In addition, when the temperature is higher than 80 °C, the organic matter that constitutes the discoloration system will also begin to degrade. Therefore, the discolored yarn should avoid working at a temperature higher than 75℃ for a long time. It should be stored in a cool, dry and dark place.

Cupro cotton blended yarn is a kind of cellulose fiber. It is made by dissolving cellulose raw materials such as cotton linters in a concentrated ammonia solution of copper hydroxide or alkaline copper salt to prepare a spinning solution. Ammonia cellulose molecular chemicals produce cellulose, and the resulting hydrated cellulose is post-processed to obtain cupro fibers. The cross-section of cupro fiber is round, without skin-core structure, the fiber can withstand high stretching, and the monofilament obtained is thinner, so the fabric feels soft, soft luster, and silk feeling. The hygroscopicity of cupro fiber is close to that of viscose fiber. Its official moisture regain is 11. Under normal atmospheric conditions, the moisture regain can reach 12-13. Under the same dyeing conditions, the dyeing affinity of cupro fiber is higher than that of viscose fiber. Large, darkly colored. The dry strength of cupro fiber is close to that of viscose fiber, but its wet strength is higher than that of viscose fiber, and its abrasion resistance is also better than that of viscose fiber. Because the fibers are soft and suitable for luster, they are often used as silk or knitted fabrics.

Bamboo charcoal fiber yarn can emit far-infrared rays with wavelengths between 4 and 14 microns. The fluctuations caused by the vibration of its light waves can release warm kinetic energy and change the structure of water molecules. This wavelength belongs to the far-infrared wavelength absorbed by the human body. It can penetrate the skin, activate human cells, promote blood circulation, and effectively reduce the incidence of cardiovascular disease. The sterilization function of bamboo charcoal fiber yarn is also widely used in various medical devices and medicines. In medicine, it can effectively kill germs in the human body, prevent the spread of bacteria, and achieve the purpose of clearing the stomach and detoxification; in medical equipment, natural and continuous disinfection of the equipment can improve the hygiene of the equipment.
