Abstract

The invention provides a soft and smooth elastic non-woven fabric and a manufacturing method thereof. The non-woven fabric comprises three layers, the upper layer and the lower layer are non-woven fabric composites, and the middle layer is elastic material PVC (polyvinyl chloride). The non-woven fabric is prepared from the following raw materials in percentage by mass: 70-80% of a non-woven fabric complex and 20-30% of an elastic material PVC (Polyvinyl Chloride), and the elastic material PVC is composed of a mixture of six raw materials including a thermoplastic elastomer L4418N, white master batch, an ethylene-propylene copolymer, polypropylene resin, dioctyl phthalate and a polyester plasticizer and a Ca / Zn liquid stabilizer. According to the invention, an extrusion spinning process is used, the elastic material PVC and the non-woven fabric complex are connected through extrusion tape casting of a laminating machine, and the non-woven fabric with softness, smoothness and extremely high elasticity is produced. The non-woven fabric produced by the method has extremely high elasticity and other mechanical properties, not only keeps the air permeability of the original non-woven fabric, but also has soft, smooth and fitting hand feeling, and meanwhile, the problem of insufficient elasticity of the non-woven fabric is also solved.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and in particular relates to a silky elastic non-woven fabric and a manufacturing method thereof. Background technique [0002] Non-woven fabric refers to the manufacture of cloth-like products that use chemical fibers as the basic raw material and are chemically or hot-melt bonded. Because it does not weave, it is also called non-woven fabric. It directly uses polymer slices, short fibers or filaments to form fibers through airflow or machinery, and then undergoes hydroentanglement, needle punching, or hot rolling reinforcement, and finally passes through The non-woven fabric formed by post-finishing. [0003] Non-woven fabrics are made of chemical fibers and plant fibers on wet or dry paper machines under the condition of water or air as the suspension medium. Although they are cloth without weaving, they are called non-woven fabrics. Non-woven fabrics are composed of ultra-fine sho...
