Manufacturing method for disposable sanitary base material and production line thereof

Abstract

The invention discloses a manufacturing method for a disposable sanitary base material and a production line for the manufacturing method. In the manufacturing method, a surface layer is formed on a net strip through net forming by first net-forming equipment; a first wrapping layer is formed on the surface layer through a net formed by second net-forming equipment; paving equipment is used for paving a water-absorbing material on the first wrapping layer to form an absorbing layer; a second wrapping layer is formed on the absorbing layer through a net formed by third net-forming equipment; and curing equipment is used for curing all the stacked layers to form the disposable sanitary base material. For the manufacturing method, on one production line, the surface layer, the wrapping layers and the absorbing layer are subjected to on-line production, and are stacked and cured together, so that the disposable sanitary base material is formed, the production steps and the production links for upstream suppliers are greatly reduced, for example, production links such as winding, unwinding, slitting and packaging for the surface layer and the wrapping layers are reduced, the rejection rate is reduced, the using amount of glue is reduced, the transportation amount is reduced, so that the cost is greatly reduced, and the function of low carbon and environmental production is achieved; and with the reduction of the using amount of glue, the product is more friendly and safer to the human bodies.

Description

【Technical field】 [0001] The invention relates to the field of non-woven fabrics, in particular to a disposable sanitary base material. 【Background technique】 [0002] Diapers are mainly used for infants, patients who cannot take care of themselves and the elderly. The emergence of diapers has greatly improved the lives of infants, patients who cannot take care of themselves and the elderly, and also facilitated the work of nursing staff and reduced the workload of nursing staff. [0003] Current diapers are divided into surface layer, covering layer (the function of covering layer is to enclose superabsorbent resin or fluff pulp), absorbent layer (superabsorbent resin or fluff pulp layer), back layer, etc. according to the structure. The surface layer and the covering layer are made of woven fabric, and the covering layer covers the absorbent layer. The back layer is generally composed of non-woven fabric, or PE film and non-woven fabric composite, or PE breathable film; s...

Problems solved by technology

[0003] Current diapers are divided into surface layer, covering layer (the function of covering layer is to enclose superabsorbent resin or fluff pulp), absorbent layer (superabsorbent resin or fluff pulp layer), back layer, etc. according to the structure. The surface layer and the covering layer are made of woven fabric, and the covering layer covers the absorbent layer. The back layer is generally composed of non-woven fabric, or PE film and non-woven fabric composite, or PE breathable film; surface layer, covering layer The non-woven fabric used in the layer and back layer is produced by the non-woven fabric factory, and then goes through winding, unwinding, slitting, rewinding, packaging, transportation and other links, and then returns to the diaper production plant. Rolling and other steps, the coating layer must be coated with super absorbent resin or fluff pulp before it can be used on the diaper production line. Not only is the process cumbersome, but it also wastes energy, wastes packaging materials, and increases intermediate transportation links and transportation costs; used for bonding during production The amount of glue is also very large, which does not conform to the concept of low carbon and environmental protection, and the excessive amount of glue used will also cause safety hazards to the skin
