Problems solved by technology

[0006] In the prior art, the hemp fiber extracted from the bast of hemp is mostly used as antibacterial fiber, but due to the excessive use of hemp fiber, the output of hemp bast is less than the demand.
There are many hemp stems, but they only use building materials, environmental protection materials and animal bedding, and no antibacterial materials are extracted for antibacterial
At present, there is no report of using hemp stalks as raw materials to manufacture sanitary products such as diapers. There is a need for a viscose fiber with hemp stalks as raw materials, and products such as diapers and sanitary napkins made from it.

Abstract

The invention relates to a preparation method of hemp stalk viscose fiber and the application of the hemp stalk viscose fiber to paper diapers. The preparation method comprises steps of material preparation, dipping pressing, crushing, ageing, sulphidizing, dissolving, filtering, debubbling, filtering before spinning, wire drawing, post treatment and the like, is simple in preparation technology, and saves cost. The method adopts hemp stalk viscose fiber extracted from hemp stalk to prepare paper diapers which have the functions of bacteria prevention, mould proof, air permeability, comfort characteristic, heat emission and radiation hardening which are characteristics of original ecology, so that compared with the prior art adopting organic and inorganic bacteria prevention, the hemp stalk viscose fiber has better bacteria prevention effect, is laundry-resistant and easy to degrade, and can be continuously utilized.

Description

technical field [0001] The invention relates to the field of daily necessities, in particular to a preparation method of hemp stalk viscose 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 C...
