Abstract

A melt spinning non-woven material is characterized in that the weight of the non-woven material weights 35 to 500 g/m<2> and being obtained by a polymer slice being directly melting to spin and the spine being weaved into webs. The melt spinning non-woven material consists of superfine fibers and crude fibers, the crude fibers are used as a framework and the superfine fibers are filled into the framework to form a fiber web to form a thickness matching structure. The fiber web has one layer or more, and when the layer number of the fiber web is more than one, a thickness increasing or gradient structure is formed through a multilayer structure. By means of the optimization of raw materials and process, the melt spinning non-woven material and a production method and an application of the melt spinning non-woven material can control a fiber web structure of the melt spinning non woven material: the distribution of fiber finenesses is controlled in a reasonable range, the fiber web has a large amount of superfine fibers and a certain amount of crude fibers; the crude fibers being used as a framework and the superfine fibers being filled into the framework improve the fluffiness of the material, and the material can still maintain some recovery capability when in use; and the fiber web forms a structure with some gradients.

Description

technical field [0001] The present invention relates to a material, in particular to the melt-spun nonwoven material, its production method, and its application. Background technique [0002] Due to the three-dimensional network structure of the fiber web, the fluffy nonwoven material has a large internal space, and the fiber web has good resilience after being compressed, and has a wide range of applications in the fields of dust holding, filtering, heat preservation, sound absorption, oil absorption, and hygiene. Applications. According to different production technologies, the current fluffy nonwoven materials mainly have the following methods: [0003] 1. Mix ordinary fibers and hot-melt fibers, and obtain hot air-type fluffy nonwoven materials through opening, carding, mechanical laying (mainly referring to parallel laying, cross-laying) or air-laid and hot-air reinforcement. [0004] 2. Use fibers with special-shaped cross-sections, through opening, carding, mechanic...
