How to get a cooling fabric?
Cooling fabrics generally use unique methods (such as modifying fiber raw materials or finishing fabrics, etc.), so that the fabrics can quickly diffuse body heat, accelerate sweating and cooling, and can maintain the coolness and cooling effect of fabrics for a long time. comfortable. Mainly used in clothing, outdoor sportswear, home textile products.
The main feature of cool fabrics is instant coolness, which is mainly reflected in the following two aspects: one is good thermal conductivity, which can quickly dissipate body heat and make the wearer feel cool. The second is good moisture conductivity, the sweat produced by the human body can quickly spread to the outer layer of clothing, take away a lot of heat, and give people a cool and comfortable feeling.
At present, the processing methods of cool fabrics include cool fibers and cool additives.
1. Cooling fiber: One is the physical blending method. The high molecular polymer masterbatch and the mineral powder with good thermal conductivity are evenly mixed, and then the cooling mineral fiber is prepared by a conventional spinning process. The other is to add food-grade xylitol to the fiber spinning solution. After spinning, xylitol can be evenly distributed on the fiber. The temperature rise under the skin heat source under the fiber is tested by an infrared temperature tester. The fiber of xylitol absorbs heat quickly. Another kind of cool feeling fiber can be realized by designing the cross section of the fiber. The shaped fiber cross section brings a longitudinal multi-groove structure to the fiber, and these grooves are conducive to the improvement of the wicking function.
2. Cooling agent: add cooling microcapsules or xylitol cooling finishing agent to ordinary textile fabrics by conventional dipping, padding or coating, so that it has the function of instant cooling.
Hello I TexTM use both of the above methods to make cooling high stretch fabrics according to customers' detailed requirement. Normally, Cooling agent is more simple and economic, but Persistence will be poor; On the contrary, the durability of the cool yarn will be better, but at the same time the process is complicated and the price is higher.
