Wood pulp is a component, non-woven fabric is a technical process, and I am curious that COFORM non-woven fabric has a wood pulp content of 70% and a PP polypropylene content of 30%. COFORM is characterized by dry air-laid, online PP melt-blown, and finally spunlace reinforcement, air-laid is relatively fluffy, rich in structure, and PP melt-blown structure is slender, which is conducive to the penetration and rebound of spunlace, and the effect of spunlace is relatively sufficient. The surface of the material PP is in a melt-blown state, the ultra-fine fiber is softer, has a better skin-friendly feel, and has no harm to the baby's skin; it is dry-laid, fluffy, and has better liquid absorption and liquid retention performance, better texture and hand feel, and better cleaning ability powerful. The wood pulp content is high, it is fluffy and thick, feels good, and has a lower cost.
In terms of wet tissue substrates, common wood pulp spunlace non-woven fabrics, viscose polyester spunlace and glued dust-free paper are common. Common white non-woven wipes (common in small packages) or printed roll kitchen wipes are spunlace spunlace spunlace spunlace spunlace spunlace and spunlace consolidation. The typical fiber ratio is 50% viscose. Glue, 50% polyester or 50% wood pulp, 50% polyester. There are also spunlace non-woven fabrics made of cotton fibers in China, which are also very good for baby wipes, and the cost is relatively high.
In addition, there is dust-free paper AIRLAID gluing process, which is relatively fluffy and soft. The disadvantage is that it is chipping, the wet strength is not good, and the surface spraying may cause allergies. Although wood pulp fibers are cheap, they are short and cannot be mechanically carded and laid. Therefore, ordinary spunlace non-woven fabrics cannot be processed by mechanical lay-up equipment. Later, with the advancement of science and technology, domestic papermaking processes or online wet-laid webs are adopted. , Spunlace processing has gradually developed, mainly used in industrial cleaning and kitchen wiping, and seldom used in the baby wipes industry. The Kefang patent has expired, and we look forward to catching up in the country in the future and similar materials and equipment will appear as soon as possible.
