Abstract

The invention relates to a non-woven fabric with high elasticity and a manufacturing method for the same. The non-woven fabric is composed of the following raw material according to weight by percentage: 2 to 3% of polypropylene, 1 to 3% of slipping agent and the rest of polyolefin elastomers. Polypropylene, polyolefin elastomers and the slipping agent are selected for raw material of the non-woven fabric; the slipping agent can be composed of erucamide or oleamide; with the slipping agent, the raw material can be smoothly delivered after melting and extrusion and melt body viscosity can be reduced; material flowing property can be improved and adhesion between products cannot be produced; the non-woven fabric with high elasticity is produced via extrusion spinning technology parameters; the non-woven fabric obtained by the method has high elasticity and other kinetic performance; original non-woven fabric ventilating property can be maintained, smooth, soft and adhesive hand feeling can be achieved; and inadequate elasticity of the non-woven fabric can be overcome.

Description

technical field [0001] The invention belongs to the field of non-woven fabric production, and in particular relates to a high-elastic non-woven fabric and a production method thereof. Background technique [0002] The American Kimberly2Clark company first produced the melt-blown elastic non-woven material. Due to its excellent performance and irreplaceable role, its research and application have been vigorously developed, and it has rapidly expanded to Europe and Japan. Melt-blown elastic non-woven fabrics are non-woven fabrics with good elasticity produced by the usual melt-blown method using thermoplastic elastomers as raw materials. Its elasticity is defined as: the material has extensibility under the action of external force, that is to say, its elongation rate is at least 60%, and at least 55% of the original elongation can be recovered after the force is removed. [0003] As we all know, melt-blown non-woven fabrics are composed of ultra-fine short fibers (usually 1-...
