Three-layered compound non-woven fabric as well as processing equipment and processing technology thereof

Abstract

The invention relates to a raw material for hygienic products and in particular relates to a three-layered compound non-woven fabric and processing equipment thereof. The three-layered compound non-woven fabric comprises an upper layer, a middle layer and a lower layer, which are compounded together, wherein the upper layer and the lower layer are PP Polypropylene) particle anti-sticking layers; the middle layer is a long fiber wood pulp layer; the two PP particle anti-sticking layers are used for covering the long fiber wood pulp layer, are knurled through a hot-pressing knurling roller and then are hotly adhered through an ultrasonic adhesion machine. The three-layered compound non-woven fabric adopts a sandwich type structure and the sandwich type structure can be used for effectively preventing wood pulp fibers from leaking out, so that the penetration performance of a product is effectively improved and dirt penetration is effectively prevented; the water retention performance islower than a wood pulp fabric; the three-layered compound non-woven fabric can be used for reducing residues of liquid in a glasses wiping process, and the friction coefficient and the flexibility arerelatively low; a wiped material can be effectively protected; the three-layered compound non-woven fabric is especially suitable for producing glasses wet tissues and has important meaning on application of glasses wet tissue products.

Description

technical field [0001] The invention relates to a sanitary product raw material, in particular to a three-layer composite non-woven fabric and its processing equipment and processing technology. Background technique [0002] With the improvement of people's living standards, the quality of life is also constantly improving, but in recent years, the problem of myopia has become more and more serious, and the phenomenon of "juvenileization" has appeared, which has created a unique product - glasses wipes ; Glasses wet wipes for wiping glasses require soaked substrates: quick-drying, no trace, decontamination and other effects. At present, most of the substrates used in wet wipes are non-woven fabrics blended with viscose and polyester in proportion, which absorbs water. Although the resistance can be controlled by viscose, the water retention performance is poor, and it is easy to squeeze out a large amount of liquid while absorbing water, which does not meet the requirements ...

[0002] With the improvement of people's living standards, the quality of life is also constantly improving, but in recent years, the problem of myopia has become more and more serious, and the phenomenon of "juvenileization" has appeared, which has created a unique product - glasses wipes ; Glasses wet wipes for wiping glasses require soaked substrates: quick-drying, no trace, decontamination and other effects. At present, most of the substrates used in wet wipes are non-woven fabrics blended with viscose and polyester in proportion, which absorbs water. Although the resistance can be controlled by viscose, the water retention performance is poor, and it is easy to squeeze out a large amount of liquid while absorbing water, which does not meet the requirements of quick drying and no trace in glasses wipes; the base paper made of wood pulp fiber has the characteristics of Low water absorption rate, the uneven structure of wood pulp itself has a good effect on decontamination and non-marking, but the wet strength of wood pulp fibers is low after being exposed to water, which cannot meet the requirements of existing machinery and wiping, and wet strength agents are added After the product is hard, the friction is large, and it is easy to wear out the product being wiped
