Abstract

The invention relates to a preparation method of ramie stalk antibacterial viscose fiber and the application of the ramie stalk antibacterial viscose fiber to baby diapers and adult diapers. The preparation method comprises the steps of squeezing, crushing, dipping, degrumming, acid and alkali treatment, cooking, alpha pulp preparing, after treatment and the like, is simple in preparation technology, and saves cost. The method combines inorganic bacteria prevention with natural bacteria prevention, and ensures that the ramie stalk antibacterial viscose fiber achieves the effect of double bacteria prevention through a surface layer and an inner core when being applied to paper diapers and sanitary towels, effectively prevents the growth and survival of various bacterium and pathogenic bacterium, and reduces the harm of secondary pollution of hygienic products, such as paper diapers and sanitary towels, to human body.

Description

technical field [0001] The invention relates to the field of daily necessities, in particular to a preparation method of ramie rod antibacterial viscose fiber and its application in diapers and sanitary napkins. Background technique [0002] At present, there are four categories of antibacterial agents: inorganic antibacterial agents, organic antibacterial agents (chemical), natural plant antibacterial agents and biological antibacterial agents. In the field of hygiene products, the antibacterial technologies currently used are mainly inorganic and organic antibacterial technologies. However, organic antibacterial is mainly chemical drug antibacterial, which has a great impact on the environment and human body, is not washable, and has poor stability; in addition, inorganic antibacterial mainly uses metal ion antibacterial technology, such as nano-silver, zinc, copper ions, etc., to manufacture It consumes a lot of energy, and it is a rare resource. The collection and proce...
