Properties of alginate fiber

The physical and chemical properties of alginate fiber made from wet spinning were tested.The results show that alginate fiber has good moisture regain,water absorption,and flame retardant property,but poor heat resistance.As the fiber turns yellowing and significant loss of strength reduction when heating to 110 ℃,it is not suitable for high-temperature treatment.Alginate fiber has poor resistance to acid and alkali.Although the fiber is not swollen in mild acid solution at room temperature,it has great impact on its strength.In addition,the salt resistance of alginate fiber is also poor,it tends swollen or even completely dissolved in the presence of salty solution containing sodium ions.
