Embodiment 1

[0026] A kind of bamboo fiber composite fiber that is used for sanitary napkin top layer of the present invention comprises the following steps to prepare:

[0027] Step 1: Preparation of yew pulp: Weigh 500 grams of yew powder, 500 grams of tea polyphenol powder, and 5 grams of monoglycerides of monofatty acid. After mixing, add 5000 grams of water and grind it into a slurry with a solid content of about 16%. Tea polyphenols 1. The dispersant is dissolved in water, and then the yew raw material powder is added under the condition of stirring and stirred evenly to obtain a mixed slurry containing yew and tea polyphenols;

[0028] Step 2: After mixing the mixed slurry and natural bamboo fiber pulp according to the stated ratio, the weight ratio of the mixed slurry and natural bamboo fiber pulp is 1:200, add 5% sodium hydroxide solution to carry out stirring reaction, at room temperature Under reaction for 2-3 hours, the spinning stock solution is obtained;

[0029] Step 3: Spi...

Description

technical field [0001] The invention belongs to the technical field of sanitary napkins, and in particular relates to a preparation method of a composite fiber in which bamboo fibers are added with yew and its application in the field of sanitary napkins. Background technique [0002] Sanitary napkin is a kind of absorbent material, the main material is cotton, non-woven fabric, pulp or high molecular polymer and high molecular polymer synthetic paper formed by the above material composites, used to absorb women's menstrual cramps from the vagina Menstrual bleeding. [0003] Sanitary napkins directly contact the mucous membranes of the human body and absorb menstrual blood. Menstrual blood is rich in nutrients and can easily become a "medium" for bacteria to multiply. The sanitary napkins currently available on the market mostly use materials such as non-woven fabrics or plastic perforated films as the surface layer, and the absorbent layer is below the surface layer. The p...
