Embodiment 1

[0038] A preparation method of hemp fiber, comprising the following steps:

[0039] 1) Peeling and soaking: peel the hemp to obtain peeled hemp, then soak the peeled hemp in a caustic soda solution with a weight ratio of 1:0.2 for 12 hours to obtain a soaking solution;

[0040] 2) Degumming: adding a hydrochloric acid solution with a volume ratio of 1:0.05 and a concentration of 40% to the soaking liquid, cooking at 95-100°C for 8 hours, and repeated cooking for 5 times to obtain finer hemp fibers;

[0041] 3) Drying: Ventilate and dry the finer hemp fibers at 60°C for 2 to 4 hours to obtain dried hemp fibers;

[0042] 4) Screening: Screen the dried hemp fibers, and collect and utilize those whose fineness reaches the requirement of 2.0D; degumming the thicker fibers until they meet the required fineness;

Abstract

The invention relates to a method for preparing a China hemp fiber, as well as an application of the China hemp fiber on paper diapers. The method for preparing the China hemp fiber comprises the following steps: removing the peel, soaking, degumming, drying and screening. The preparation process is simple, and the cost is saved. The paper diapers are prepared by using the China hemp fiber and have the originally ecological special antibacterial, mould-proof, ventilating, comfortable, radiating and anti-radiation effect; and therefore, compared with the organic and inorganic antibiosis in the prior art, the China hemp fiber is good in antibacterial effect, washing-resistant and easily degradable and can be sustainably utilized; and moreover, the China hemp fiber is good in antibacterial effect, prevents diaper rash and bedsore, is washing-resistant, easily degradable and environment-friendly and can be sustainably utilized, and the resources are saved.

Description

technical field [0001] The invention relates to the field of daily necessities, in particular to a preparation method of hemp fiber and its application in diapers and sanitary napkins. Background technique [0002] In the field of diapers, the antibacterial technologies currently used are inorganic and organic. However, organic antibacterial is mainly chemical antibacterial, which has a great impact on the environment and human body, and is not washable; inorganic antibacterial mainly uses metal ion antibacterial technology, such as nano-silver, zinc, copper ions, etc., but cannot be degraded. consumes resources and pollutes the environment. Therefore, there is an urgent need to develop an antibacterial material that has strong antibacterial ability, has no toxic effect on the human body, and has no pollution in the production process, so as to solve the antibacterial problem in the field of hygiene products. [0003] Hemp, also known as hemp, originated in China. It is kn...
