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 passes through the diaper production factory. In steps such as unwinding, the coating layer must be coated with super absorbent resin or fluff pulp before it can be used on the diaper production line. The amount of glue used 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

Embodiment 1

[0033] Such as figure 2 As shown, the surface layer 1 is realized by the first carding equipment 7 using the carding process, which is composed of short fiber hydrophilic treatment→drying→short fiber feeding and weighing→mixing and opening→multi-compartment blending→cotton transportation →air fiber separation→cotton box→opening→cotton feeding→repeated opening→repeated feeding→feeding→carding→laying to form surface layer 1 with fiber fineness between 1.5-4 denier. The first cladding layer (guiding layer) 21 is realized by the second carding equipment 8 carding process, but the fiber fineness will be smaller than the surface layer 1, between 0.1-2 deniers, the first cladding layer (The diversion layer) 21 is superimposed on the surface layer 1, and is transported to the paving equipment 9 by the mesh belt 12, and the superabsorbent resin or fluff pulp is evenly spread on the superimposed surface layer 1 and the first cladding layer 2, The absorbent layer 3 is formed; the pavin...

Embodiment 2

[0035] Such as image 3 As shown, the difference between this example and the first embodiment mainly lies in that the fiber web of the first cladding layer 21 is realized by the second spinning equipment 16 using a spun-web process, and the spun-web process flow includes: Co-conveying of polymer chip raw materials and hydrophilic masterbatch→quantitative mixing and feeding→melt extrusion of screw extruder→melt filtration→quantitative metering of metering pump→melt distribution→spinneret spinning→fiber quenching→fiber airflow Drafting→fiber splitting and laying. In this example, the second spinning device 16 is a spunbond spinning device.

Embodiment 3

[0037] Such as Figure 4As shown, the surface layer 1 is realized by the first spinning equipment 15 using the spinning-forming process. The spinning-forming process includes: high polymer chip raw materials and hydrophilic masterbatches are conveyed together → quantitative mixing and feeding → screw Extruder melt extrusion→melt filtration→quantitative metering by metering pump→melt distribution→spinneret spinning→fiber quenching→fiber air drafting→fiber splitting and laying to form surface layer 1, fiber fineness Between 1-4 Daniel. The fiber web of the first cladding layer 21 is realized by the second spinning equipment 16 using a spinning web process, but the fiber fineness will be smaller than that of the surface layer 1 fiber web, between 0.1-2 deniers, the first bag The coating layer 21 is superimposed on the surface layer 1 and transported to the spreading equipment 9 through the mesh belt 12 . The spreading equipment 9 evenly spreads superabsorbent resin or fluff pulp...

Abstract

The invention discloses a disposable health substrate, comprising a surface layer, a first coating layer, an absorbing layer and a second coating layer which are overlaid in sequence and fixedly connected into a whole. Simultaneously, the invention also discloses application of the health substrate in disposable diapers. The technical scheme is as follows: the surface layer, the coating layers and the absorbing layer are produced in an online manner and overlaid and fixedly connected into whole to form the disposable health substrate; the disposable health substrate can be directly used for the disposable diapers combined with a back layer, so that the production steps and links of upstream diaper suppliers can be reduced greatly, and the cost is lowered greatly, and the effects of low carbon and environmental protection can be achieved; and due to the reduction of the glue using amount, the health substrate is comfortable and safe for people.

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...
