Chemical bamboo fibers include bamboo pulp fibers and bamboo charcoal fibers.
Bamboo pulp fiber: Bamboo pulp fiber is a kind of pulp made from bamboo, then the pulp is made into pulp and then wet-spun into fiber. The manufacturing process is basically similar to that of glue. However, the natural characteristics of bamboo are destroyed during processing, and the deodorization, antibacterial and anti-ultraviolet functions of the fiber are significantly reduced.
Bamboo charcoal fiber: It is a fiber product which is selected from nanometer bamboo charcoal powder and added into viscose spinning solution through special process and then weaved by similar conventional spinning process.
Bamboo charcoal fiber manufacturing process:
Carbonization of bamboo (heating the alpine bamboo with bamboo age of 5 years or more to 450~550 °C for carbonization, and then carbonizing at high temperature, that is, after the above low temperature carbonization project, the char is heated again to 800~900 °C for continuous treatment) → Activated bamboo charcoal (The bamboo charcoal after the above two kinds of heat treatment is sprayed, and the bamboo charcoal is rapidly cooled and fired. At this time, due to the physical and chemical action of water, the bamboo charcoal produces a complex porous structure, and the surface area is increased several times, and the sorption is greatly improved. Capacity. Activated bamboo charcoal has a high density of tissue bonding and is extremely hard. The carbon rate can reach more than 85%.) → Pulverization of bamboo charcoal (the activated activated bamboo charcoal is pulverized to produce sub-nanometer bamboo charcoal powder) → Disperse evenly (mix the bamboo charcoal powder into the original pulp such as polyester or viscose and stir it to disperse it evenly in the puree) → Spinning (from the puree, through the spinning equipment, the filaments containing bamboo charcoal powder can be extracted, or cut into cotton or wool staple fibers, medium and long fibers, etc. as needed to obtain bamboo charcoal fibers)
