Abstract

The invention provides a spun-bonding dual-component PP (Propene Polymer) / PE (Polyethylene) hot-air reinforced non-woven material. The spun-bonding dual-component PP / PE hot-air reinforced non-woven material is of a skin-core type composite structure, wherein a skin layer is prepared from a PE material, a core layer is prepared from a PP material, the melting index of the PP material is 20 to 45 g / 10min, and the melting index of the PE material is 10 to 25 g / 10min. The spun-bonding dual-component PP / PE hot-air reinforced non-woven material is prepared through the following steps: respectively melting the PP material and the PE material through a screw extruder, thus obtaining a PP melt and a PE melt; enabling the PP melt and the PE melt to enter a composite spinning plate after passing through a metering pump, extruding extruded composite filaments from a spinneret orifice, and carrying out air drawing and lapping after cooling, thus forming a PE / PP web on a web forming apron; finally,carrying out hot-air bonding, thus preparing the non-woven material. The spun-bonding dual-component PP / PE hot-air reinforced non-woven material prepared by the invention is smooth in surface, flat and uniform, a PP filament part in the core layer in a bonding zone is still kept in a monofilament form, the strength is large, the tensibility is better, the hand feeling is soft, and comfort and safety are realized.

Description

technical field [0001] The invention relates to the field of nonwoven fabrics, in particular to a spunbond two-component PP / PE hot air reinforced nonwoven material. Background technique [0002] The surface materials of previous products such as sanitary napkins and paper diapers are thin products, which are made of short fibers carded into a web, and then hot-rolled or hot-air-treated. There is a significant contradiction between strength and softness in nonwoven fabrics. Good strength, poor flexibility; good flexibility, strength can not meet the requirements. The problem of low strength caused the equipment to be unsatisfactory for highly processed diapers. Although the hot-air nonwoven fabric feels soft and comfortable, its surface is uneven, with many fluff heads and hairiness. In this way, it will be in contact with the skin during use, rubbing and irritating, causing skin rashes and itching. In addition, in the process of cleaning, carding and web forming of short ...
