Embodiment 1
[0031] Embodiment 1, the preparation of chitosan oligosaccharide essence fiber
[0032] The preparation method of described chitosan oligosaccharide essence fiber is as follows:
[0033] A: Add chitosan oligosaccharide into water, add acetic acid dropwise to adjust the pH to 4, stir and dissolve, configure an aqueous solution of chitosan oligosaccharide with a mass concentration of 8%, and add epoxy chlorine with a mass ratio of 0.3:1 to chitosan oligosaccharide Propane, heated to 70°C, stirred for 2.5 hours to obtain material A;
[0034] B adjusts the pH of the material A to be 8, adds it to the viscose fiber with a mass ratio of 2.5:1 to oligochitosaccharide, stirs and reacts for 2 hours, removes epichlorohydrin by suction filtration under reduced pressure, and obtains material B;
[0035] C spread material B flat with a thickness of 2±0.5cm 60 Co-γ-ray irradiation, the dose of irradiation is 3.0kGy-5.0kGy, adding to distilled water with a mass ratio of 50:1 to material B,...
Embodiment 2
[0036] Embodiment 2, the production technology of antiseptic facial mask
[0037] The production process steps of described preservative-free facial mask are as follows:
[0038] S1: Preparation of modified non-woven facial mask: weave the chitosan oligosaccharide essence fiber obtained in Example 1 into a net shape with a thickness of 0.2mm, dry it, and cut it into a circular mask with a length of 17cm and a width of 16cm to obtain the final product ;
[0039] S2: Preparation of mask essence: add 5 parts of hydroxyethyl chitosan, 5 parts of β-glucan, and 2.5 parts of cell growth factor into 30 parts of 40°C water, stir and dissolve evenly, and then add sodium hyaluronate 0.5 parts, stir evenly to get;
[0040] S3: After soaking the modified non-woven fabric mask prepared in step S1 in the 20mL mask essence prepared in step S2, put it into a mask bag, spread it flat, pack it into a box, and place it in an oxygen-free environment at 35°C 60 Co-γ-ray irradiation, the irradiat...
Embodiment 3
[0041] Embodiment 3, the production technology of preservative-free facial mask
[0042] The production process steps of described preservative-free facial mask are as follows:
[0043] S1: Preparation of modified non-woven facial mask: weave the oligochitosan essence fiber obtained in Example 1 into a net shape with a thickness of 0.5 mm, dry it, cut it into a circular mask with a length of 23 cm and a width of 20 cm, to obtain ;
[0044]S2: Preparation of facial mask essence: Add 4 parts of hydroxyethyl chitosan, 6 parts of β-glucan, and 3 parts of cell growth factor into 30 parts of 50°C water, stir and dissolve evenly, and then add sodium hyaluronic acid 0.8 parts, stir evenly to get;
[0045] S3: Soak the modified non-woven fabric mask prepared in step S1 in the 20mL mask essence prepared in step S2, put it into a mask bag, spread it flat, pack it into a box, and place it in an oxygen-free environment at 40°C 60 Co-γ-ray irradiation, the irradiation dose is 5.0kGy-8.0k...
