Embodiment 1
[0034] The present embodiment provides a kind of processing method of industrial hemp, comprises the following steps:
[0035] (1) Crush the industrial hemp stem to 60-120 mesh, mix it with water at a mass ratio of 1:1, stir it fully and let it stand for 60 minutes. After it fully absorbs water, filter to remove excess water, and control the content of the obtained hemp pulp The water volume is 40%;
[0036] (2) Add lye (concentration is the mixed solution of 5% sodium carbonate and 8% sodium bicarbonate with a concentration of 8% sodium bicarbonate in the gained hemp pulp, the consumption of lye is 30% of hemp pulp weight), at 50 DEG C Boiling for 75 minutes, after the treatment is completed, centrifuged to obtain a slurry with a water content of 10.5%, and waste lye;
[0037] (3) Pulverize the obtained slurry block, after crossing 80 mesh screens, lay it flat on the platen, control the thickness of the material layer to be less than 3 cm, place it for 3 hours under natural ...
Embodiment 2
[0043] This embodiment provides a method for processing industrial hemp. On the basis of Embodiment 1, the method provided by this embodiment further includes the following steps.
[0044] The hemp skin is naturally air-dried until the water content is lower than 11%, then boiled in water for 40 minutes to soften it, remove it and put it into the waste lye obtained in step (2) of Example 1, and soak it for 60 minutes at 80° C.; then Wash until the surface pH is lower than 7.5, put it in a closed container, and cook at 110°C for 3 hours; then wash, press water, and dry until the water content is lower than 45%; then perform ozone bleaching, and the concentration of ozone treatment is the weight of dry matter The processing time is 2 minutes; flat laying, stretching, hot air drying at 90°C, cooling to room temperature, spinning out, forming hemp fiber, and storing.
[0045] The various data of the hemp fiber prepared in this embodiment conform to the second-class product of "GB / ...
Embodiment 3
[0047] This embodiment provides a facial mask paper. The raw materials of the facial mask paper include 80% of the hemp stalk viscose fiber prepared in Example 1 and 20% of the hemp husk fiber prepared in Example 2 by weight percentage.
[0048] The preparation method of the facial mask paper of this embodiment is a conventional blending method in the art.
