the quality of sanitary napkin raw materials

Are you still worried that sanitary napkins are made of inferior materials such as recycled cotton? In fact, regular factories have very strict control over raw materials. Common materials for sanitary napkins include super absorbent polymers, pouch films, backsheet films, fluff pulp, and non-woven fabrics. There are tricks to distinguish the quality of them.   Super absorbent polymers are used to quickly absorb and lock liquids to keep the surface dry. Regular polymer particles are uniform and free of impurities, while recycled products have different particle sizes and obvious impurities due to mixed processing.   Fluff pulp is made from natural native wood, with good water absorption and fiber strength, which can improve the product's water absorption capacity and comfort. Regular fluff pulp is natural native wood pulp that meets national standards, which is dehydrated and compressed to form a plate or roll. The recycled fluff pulp is taken out from discarded sanitary napkins and is fluffy in itself, without rolls or plate shapes.   The backsheet film plays a role in blocking leakage and fixing the position, and the wrapping film can isolate dust and ensure cleanliness and safety.The secondary recycled backsheet film and small packing film absorb dust and impurities due to the presence of glue, fluff pulp and other substances, resulting in uneven appearance and touch. The ash content of the residue after burning generally exceeds 10%; the non-recycled ones have no impurities and the ash content does not exceed 5%.   As the topsheet layer, the non-woven fabric plays the role of absorbing menstrual blood and keeping the surface dry. It cannot be recycled again and become non-woven fabric for production, because it can only be turned into particles after recycling and cannot be turned into cloth again.   Mastering these key points, you can easily distinguish the quality of sanitary napkin raw materials!   If you need know more information, please click www.glinknonwoven.com
