Description
Technical Field
The invention relates to a preparation method and application of health-care fibers.
Background
Along with the improvement of living standard of people, the attention of people to the health care performance of wearing articles is also improved, and the health care function of textiles is also increasingly improved.
Hemp is a natural annual herb, and the fiber has the characteristic of high strength, so that the hemp can be used as a raw material for spinning clothes. The existing hemp fiber treatment process is as follows: manually picking and sorting the original hemp, sorting the head and the tail, clearing the bundle, then performing dry softening on the hemp by using a hemp softening machine, binding the dried and softened hemp bundle, caging the hemp, cooking the hemp, and washing the cooked hemp with hot water; then scutching, dehydrating, softening, deoiling, fluffing and picking the ramie to obtain the refined dry ramie. The fibrilia has good air permeability, and the clothes made by weaving are comfortable. However, the fibrilia cloth is easy to wrinkle and has no health care performance.
Disclosure of Invention
The invention provides a preparation method of hemp health-care fibers, aiming at solving the technical problems that the existing hemp fiber cloth is easy to wrinkle and has no health-care performance.
The preparation method of the hemp health-care fiber comprises the following steps:
firstly, boiling and refining raw hemp: adding sodium hydroxide and trisodium phosphate into water to dissolve according to the concentration of 10-12 g/L of sodium hydroxide and the concentration of 2-5 g/L of trisodium phosphate to obtain a mixed solution; immersing raw hemp in the mixed solution, heating to 95-100 ℃, keeping for 1-1.5 hours, and washing with water at 50-70 ℃;
II, enzyme treatment: immersing the hemp fibers treated in the step one into 0.5U/mL Cellic CTec2 cellulose complex enzyme solution, keeping for 8-12 h at 50-70 ℃, fishing out, washing with 50-70 ℃ water, dehydrating and drying;
thirdly, immersing the hemp fibers treated in the second step into a sodium hypochlorite solution with the effective chlorine concentration of 1-1.5 g/L, bleaching for 20-30 minutes, fishing out, washing with water, and dehydrating and drying;
fourthly, firstly, adding hazelnut oil and functional essential oil into the base oil, and uniformly mixing to obtain mixed oil; adding the mixed oil and the emulsifier into water, and uniformly mixing to obtain a modified solution; and (3) immersing the hemp fibers treated in the step three into the modification liquid, performing immersion treatment at the temperature of 55-60 ℃ for 1-2 hours, taking out and drying to obtain the health care hemp fibers.
Furthermore, the ratio of the mass of the hemp fibers to the volume of the Cellic CTec2 cellulose complex enzyme solution with the concentration of 0.5U/mL in the second step is 1 kg: (20-50) L;
further, the functional essential oil in the fourth step is lavender essential oil, rose essential oil, tea tree essential oil or lemon essential oil;
further, the base oil in step four is olive oil, coconut oil, or jojoba oil;
furthermore, the concentration of hazelnut oil in the modified liquid in the fourth step is 10-15 g/L, the concentration of functional essential oil is 1-5 g/L, the concentration of base oil is 15-30 g/L, and the concentration of emulsifier is 0.2-0.5 g/L;
further, the emulsifier is tween 60 or tween 80.
In the method, during the process of boiling-off the hemp, the cellulose and the hemicellulose are swelled by sodium hydroxide, and then enzyme treatment is carried out, so that the fiber structure in the hemp bast is loosened, the hemicellulose is cracked and changed into monosaccharide to be dissolved after the enzyme permeates into amorphous lattices of the hemicellulose, and meanwhile, the cellulose is also etched, and the pore structure of the hemp bast creates conditions for loading the modifier; after the modification treatment, the hazelnut oil and the functional essential oil enter the pore passages of the hemp and are combined with the hemp to soften the hemp fiber. The health care hemp fiber prepared by the method has aromatic taste, and simultaneously has health care effect on skin through slow volatilization of hazelnut oil and functional essential oil. The slow-release hazelnut oil can moisten the contacted skin, so as to avoid the skin from drying and cracking, and the slow-release functional essential oil can improve the comfort level.
The hemp health-care fiber can be used for preparing functional health-care clothes.
