Embodiment Construction
[0016] A preparation method of elastic non-woven fabric, comprising the following steps:
[0017] S1. The fatty acid or fatty alcohol and the A2B2A type block copolymer are mixed and extruded into fibers according to the mass percentage, and the non-woven fabric is prepared by the melt-blown method; the fiber raw materials are plant fibers, elastic fibers and cellulose ester fibers according to the mass percentage. Mixing and dispersing are carried out; the fatty acid or fatty alcohol accounts for 35% by weight of the non-woven fabric, and the number of C atoms in the fatty acid or fatty alcohol is 12-24. The A2B2A type block copolymer accounts for 65% by weight of the non-woven fabric, the A component is polystyrene, and the B component is polyethylene-butylene.
[0018] S2, uniformly spray the dispersed mixed fiber raw material and viscose fiber to the non-woven fabric at the same time, so that the mixed fiber raw material is evenly bonded to the non-woven fabric;

Abstract
The invention discloses a preparation method of elastic non-woven fabric. The preparation method comprises the following steps: S1, mixing fatty acid or fatty alcohol and an A2B2A type segmented copolymer according to mass percent, and extruding to obtain fibers; preparing the non-woven fabric by adopting a fusing-spraying-process net forming method; S2, uniformly spraying dispersed mixed fiber raw materials and viscose at the same time on the non-woven fabric so as to uniformly stick the mixed fiber raw materials on the non-woven fabric; and S3, combining the non-woven fabric through a compression roller and a resin film, and carrying out edge reinforcing to prepare the needed elastic non-woven fabric. According to the preparation method, a plurality of types of chemical fibers with stronger elasticity are used for sticking and mixing, and a plastic thin film and the resin film are used, so that the elasticity of the prepared non-woven fabric is further enhanced and the application range of the non-woven fabric is enlarged.
Description
technical field [0001] The invention relates to the technical field of textile materials, in particular to a method for preparing elastic nonwoven fabrics. Background technique [0002] Because non-woven products are rich in color, bright and bright, fashionable and environmentally friendly, widely used, beautiful and generous, with various patterns and styles, and are light in weight, environmentally friendly and recyclable, they are internationally recognized as environmentally friendly products that protect the earth's ecology; Used in agricultural film, shoemaking, tanning, mattresses, quilts, decoration, chemical industry, printing, automobiles, building materials, furniture and other industries; but ordinary non-woven fabrics have poor wear resistance and are used as shoe toe linings When its firmness does not meet the requirements. Contents of the invention [0003] In view of the above problems, the object of the present invention is to provide a preparation metho...
