▎ 摘　　要

NOVELTY - Preparation method of hot-air non-woven fabric for electrostatic cotton masks, involves taking the polyethylene/polypropylene (PE/PP) composite fiber with the core structure of the electret masterbatch as the raw material, feeding, opening, blending, carding, hot air bonding, cooling, hydroentangling, drying and performing electret treatment to obtain the hot-air non-woven fabric for the electrostatic cotton mask. USE - The method is used for preparation of hot-air non-woven fabric for electrostatic cotton masks (all claimed). ADVANTAGE - The prepared fabric has an electrostatic effect, enhances the filtering effect of the mask, and has long electrostatic storage time, which makes high filtering effect of the mask and highly durable. The fabric has high ventilation effect, supports the space inside the mask, reduces the breathing resistance when wearing the mask, and reduces the atomization phenomenon. The fabric has high fluffy effect, where one side is relatively smooth and lint-free, and the other side is relatively fluffy. The fabric is applied to mask products to improve the comfort of wearing the mask.
