The lint pulp in sanitary napkins is actually just wood pulp that has undergone a special process. Most of the internal composition of sanitary napkins is wood pulp, which has good toughness, long fibres, less dust, good absorption and good diffusion when used, so most sanitary napkins are filled with wood pulp.

Around 2-3 hours. During menstruation, it is recommended that sanitary napkins should be changed every 2-3 hours, especially when the temperature is high. Because sanitary napkins do not breathe well, if you do not change them in time, you will leave your perineum in a damp state for a long time, which will stimulate itching, redness and swelling of the skin. In addition, bacteria can easily grow over time, which increases the risk of gynaecological diseases. Not changing sanitary napkins for a long time may also lead to the overflow of menstrual blood, which can cause contamination of clothing.

Material Lint pulp sanitary napkins are mainly made from wood pulp, which is processed and sterilised, while absorbent factor sanitary napkins are made from polymeric absorbent resin. Absorbency Although fluffy pulp sanitary napkins contain longer fibres and are more absorbent, they are not as absorbent as absorbent factor sanitary napkins and water tends to penetrate through them.

The main ingredient is cotton. Sanitary napkins are a relatively absorbent substance, mainly made from cotton, non-woven fabric, pulp and a variety of polymeric materials. Although it is a complex material to make, the main material used to make sanitary napkins is cotton, which accounts for almost 70% of sanitary napkins.

No matter what pulp is used, it is all fiber from the point of view of paper-making applications. However, there are significant differences between the various fibers. Bamboo pulp fibers are characterized by long length, thick cell walls, relative roughness and good toughness, while wood fibers are more delicate and soft. In addition, the processing properties and overall performance of wood pulp are superior to those of bamboo pulp. About 95% of the world's paper is wood pulp paper.

Tissue paper is processed from waste paper and requires a tissue machine; if tissue paper is processed from semi-finished products, a tissue rewinder is required. The range of tissue paper machines is relatively wide and can be either a tissue paper making machine or a tissue paper processing machine. Tissue rewinder is just tissue paper processing equipment. Generally, we use tissue paper machine as paper making machine and tissue rewinder as post-processing equipment.

No, polypropylene fiber is a specially treated polypropylene monofilament, which is a non-toxic and safe material that meets the requirements of today's society for clean and environmentally friendly high-tech materials.

Ordinary N95 masks are not suitable for long time wearing, because N95 masks have poor breathability, and you will feel breathing difficulties when wearing them for a long time. Breathing valve is to improve the breathing difficulty of N95 mask. The breathing valve closes during inhalation and opens during exhalation. A mask with a breathing valve is more comfortable because breathing and inhalation will be smoother. (N95 is not breathable and carbon dioxide is present in traditional masks)
