Example Embodiment

[0023] The following describes the present invention in further detail with reference to the accompanying drawings, but it does not limit the protection scope of the present invention.

[0024] Such as figure 1 As shown, a spunbond two-component fiber non-woven fabric includes an upper layer 1 and a lower layer 2 that are compounded together. The upper layer 1 is composed of 48.5% PP particles, 49% PE particles and 2.5% metallocene low-temperature particles through a screw extruder. The two components are respectively extruded through a two-component spinneret to form a "skin core". "The surface layer of the PE is bonded to each other to form a surface layer structure. The lower layer 2 is composed of 48.5% of PP particles, 49% of PE particles and 2.5% of metallocene low temperature particles. Two components are extruded through a screw extruder. Then, the bottom structure formed by bonding the surface layer PE of the "skin-core" structure to each other is sprayed through the two...

Abstract

The invention discloses a spun-bonded two-component fiber non-woven fabric, which comprises an upper layer and a lower layer, and the upper layer is composed of 48.5% PP particles, 49% PE particles and 2.5% metallocene low-temperature particles passing through a screw extruder After extruding the two component products respectively, the surface layer structure of the surface layer PE with the "skin-core" structure is sprayed out through the two-component spinneret hole. The lower layer is composed of 48.5% PP particles, 49% PE particles and 2.5% metallocene low-temperature particles are extruded through the screw extruder to extrude the two component products, and then sprayed out through the two-component spinneret. The surface layer structure and the bottom layer structure are embossed and heat-sealed by "bump-type" hot rolls. The invention has excellent bulkiness and softness, especially the interlayer peeling force, which can achieve the same effect as that of hot-air composite non-woven fabrics, and the spun-bonded penetrability and reverse osmosis performance are obviously better than hot-air products.

Description

technical field [0001] The invention relates to a sanitary product raw material, in particular to a spun-bonded two-component fiber non-woven fabric and its processing equipment and processing technology. Background technique [0002] With the improvement of people's living standards, the hygienic products industry continues to develop, and hygienic materials are also blooming everywhere. Very good application; but currently the most used materials for sanitary products are hot air, hot rolling, one-component spunbond, spunlace, etc.; thermal bonding (hot air, hot rolling) materials have good bulkiness and good infiltration performance. However, the reverse osmosis performance is poor, and the hand feels hard after secondary processing; the one-component spunbond products have good seepage performance and high softness, but post-processing is difficult; the bulkiness is low, and although the softness of spunlace products is good, it is difficult to The heavy demand is very ...
