Antibacterial ES composite short fiber for hot-air non-woven fabric surface layer and preparation method thereof

Abstract

The invention discloses an antibacterial ES composite short fiber for a surface layer of a hot air non-woven fabric. The ES composite short fiber has a skin-core structure, that is, is composed of a core layer and a skin layer; wherein, the core layer includes the following raw materials in parts by weight : 90-97 parts of polypropylene, 2-5 parts of ethylene-propylene copolymer; the skin layer includes the following raw materials by weight: 85-95 parts of polyethylene, 5-7.5 parts of methyl methacrylate graft-modified polyethylene, 3 to 6 parts of ethylene propylene copolymer and 6 to 9 parts of composite antibacterial agent; the composite antibacterial agent comprises the following raw materials by weight: chitin grafted sodium polyacrylate superabsorbent resin and acrylic acid-2-acrylamide-2-methyl 70-85 parts of sulfonic acid copolymer, 25-37 parts of silver nitrate, and 5-9 parts of nano silver. The hot air non-woven surface layer of the present invention uses antibacterial ES composite short fibers, has high antibacterial efficiency and lasting antibacterial effect, and the obtained hot air non-woven surface layer has good softness, good texture, high vertical and horizontal strength, and durability.

Description

technical field [0001] The invention relates to the field of composite fibers, in particular to an antibacterial ES composite short fiber for air-through non-woven fabric surface layer and a preparation method thereof. Background technique [0002] The hot air non-woven fabric belongs to one of the hot air bonding (hot rolling, hot air) non-woven fabrics. Bonded nonwovens. [0003] Composite fiber is a differentiated composite fiber, which refers to two or more fiber-forming polymer melts or concentrated solutions, using the differences in components, ratios, viscosities, etc., respectively input into the same spinning assembly, and in the assembly Appropriate parts are merged and sprayed from the same spinneret hole to make different types of fibers such as side-by-side type, core-spun type, sea-island type, and star-shaped type. To a certain extent, composite fibers can complement each other and fill in defects. At present, composite fibers mainly include ES fibers, sea...
