The dust-free paper thermal bonding method is to mix hot-melt fibers into the fluff pulp fibers, and the mixing ratio is generally not less than 15%. After air-laid, the low-melting fibers in the web are melted by hot air or hot rolling to form the web. Reinforce into a cloth. The thermal bonding nonwoven fabric is mainly used as an absorbent core for a highly absorbent sanitary product, a thin sanitary napkin, and the like because it does not contain a chemical binder and has a fluffy and hygroscopic property. Based on such use, some production lines are equipped with a high absorption resin (SAP) powder application device. Since the polymer water-absorbent resin is added, water can be turned into a solid after water absorption, which greatly improves the water absorption capacity.
Non-woven fabric is a kind of non-woven fabric, which directly uses high polymer chips, short fibers or filaments to pass the fibers through airflow or mechanical netting, and then through hydroentanglement, needle punching, or hot rolling reinforcement, and finally finishing. Formed non-woven fabric.
