Abstract

The invention discloses a preparation method of multi-functional non-woven fabric. The preparation method comprises the following steps: A, preparing impregnation slurry with high pore volume, high air permeability and high moisture permeability; B, immersing PET non-woven fabric into the impregnation slurry with high pore volume, high air permeability and high moisture permeability, carrying outpressing and rolling, and then carrying out solidification, washing and drying to obtain pretreated PET impregnated non-woven fabric; C, preparing blade coating slurry with high pore volume, high airpermeability and high moisture permeability and E, coating the pretreated PET impregnated non-woven fabric with the blade coating slurry with high pore volume, high air permeability and high moisturepermeability by adopting a scraper, a first coating thickness being 50+ / -1 g / m<2>, and baking at 75 DEG C until the slurry is half-dry; and coating for the second time, the second coating thickness being 40+ / -1 g / m<2>, and drying at 102 DEG C. The obtained multi-functional non-woven fabric is high in antiviral activity for African swine fever, large in peculiar smell reduction rate, high in normalemissivity, good in antibacterial effect, excellent in mechanical properties such as tensile strength, soft in hand feeling, good in air permeability, and good in comprehensive use performance.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a multifunctional nonwoven fabric and a preparation method thereof. Background technique [0002] Non-woven fabric, also known as non-woven fabric, is composed of directional or random fibers. It is a new generation of environmentally friendly materials. It can be recycled and reused, and it is called cloth because of its appearance and certain properties. [0003] Non-woven fabrics are widely used in hygienic fields such as surface materials of high-grade disposable absorbent articles or other related fields. But its function is mainly to use chemical agents to obtain functions such as disinfection and antibacterial, or to add related physical materials to obtain a single function. [0004] As a polymer material, ethylene-vinyl acetate copolymer (EVA) has good plasticity, elasticity and processability, and the EVA material after foaming treatment has the advantages o...
