Rhodiola rosea viscose fiber and producing process thereof

The invention provides a rhodiola rosea viscose fiber of which the dry-cracking strength is 2.20-2.50 N/dtex, the wet-breaking strength is 1.00-1.50 cN/dtex, the linear density deviation is 0.50-0.17%, the dry-breaking elongation rate is 18.0-20.0%, the oil content is 0.19-0.26% and the moisture regain rate is 10.8-11.5%. The rhodiola rosea viscose fiber has an anti-bacterial and odor-resistant effect, can inhibit growth of bacteria and fungus, can relieve allergy in people due to dust and can effectively avoid asthma, allergy and the like diseases. The rhodiola rosea viscose fiber also has the advantages of moisturizing and breathability and being comfortable to wear so that the rhodiola rosea viscose fiber is wide in application. In addition, a fabric prepared from the viscose fiber achieves a drug effect of rhodiola rosea, so that the fabric can functionally auxiliarily treat diseases for long period. The viscose fiber satisfies a new concept of green and environment protection.
