Problems solved by technology

At present, it is common to use a strong aromatic substance to cover up the odor or mix it with a neutralizer so that people do not feel the odor; or use the adsorption of bamboo charcoal to absorb the odor. In terms of functional fibers, this is useful. The principle of making bamboo charcoal fiber is introduced, but the color of the prepared fiber is black or gray, which is not conducive to post-processing such as dyeing, and the elimination of odor is mainly due to odor and unsaturated compounds with large molecular diameters, such as benzene, mercaptan, etc. , the type of absorption is limited, and it cannot play a role in sweat odor
At present, deodorant fabrics on the market are mainly processed through post-finishing, that is, deodorant materials with different principles are made into deodorant finishing agents. Functional components react or adsorb on the surface of the fiber; although the deodorizing effect can be achieved through post-finishing processing methods, since the auxiliary agent only stays on the surface of the fabric, it may be removed after repeated washing, so there are certain limitations
If the fibers or yarns are directly impregnated and deodorized, the adsorption capacity of the woven fabrics to the deodorizing components will be greatly increased, and the washing resistance of the fabrics will be greatly improved. After the thread is treated, it will have a great impact on its dyeing, finishing and other processes. At the same time, the washing or other chemical treatments in the subsequent treatment process may also have an impact on the deodorizing effect.
