The preparation of bamboo fiber

Chemistry class

Chemical bamboo fiber includes bamboo pulp fiber and bamboo charcoal fiber

Bamboo pulp fiber: Bamboo pulp fiber is a kind of bamboo slices made into pulp, and then the pulp is made into pulp pulp by wet spinning to make fiber, its production process is basically similar to viscose. However, the natural properties of bamboo were destroyed during the processing, and the functions of deodorization, antibacterial and ultraviolet protection of bamboo fiber were obviously decreased

Bamboo charcoal fiber: is the selection of nanometer bamboo charcoal micro powder, after a special process to add viscose spinning liquid, and then similar to the conventional spinning process of textile fiber products.

Bamboo charcoal fiber manufacturing process: Bamboo bamboo char (the age of 5 years of alpine bamboo charing heating to 450 ~ 550 ℃, and then high temperature carbonization, namely in the low-temperature carbonization engineering, after again the carbon heating to 800 ~ 900 ℃, continuous processing) and bamboo charcoal activeness (will go through the above two kinds of bamboo charcoal to spray treatment after heat treatment, sharp cooling bamboo charcoal fire, At this time, due to the physical and chemical action of water, the bamboo charcoal produced complex porous structure, the surface area increased several times, greatly improving the absorption capacity. After the activated treatment of bamboo charcoal, its tissue density increased, become very hard. Carbon rate can reach more than 85%) and the shattering of the bamboo charcoal (the activeness of bamboo charcoal to crush, made of bamboo charcoal powder in the nanoscale) - > evenly dispersed (such as bamboo charcoal powder mixed with polyester and viscose and stir in the virgin pulp, which was dispersed evenly in the protoplasmic) - > spinning (drawn from virgin pulp, through spinning equipment, filament containing bamboo charcoal powder, Can also be cut into cotton or wool type staple fiber, long fiber, etc., so as to make bamboo charcoal fiber)

Extraction process

(1) Roll along the growth direction of bamboo with a roller;

(2) The crushed bamboo obtained from the first process is fibrosed by a hammer-mill type grinder with a special mechanism;

(3) Separate the thin skin of bamboo mixed in the fiber from the second process.
