Spunbond two-component fiber non-woven fabric and processing equipment and technology thereof

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 ...

[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 high, and the cost pressure is high in the process of mass production
