Abstract

The invention discloses a skin-friendly low-permeability ES composite short fiber for a hot-air non-woven fabric surface layer. The ES composite short fiber has a skin-core structure and consists of acore layer and a skin layer, wherein the core layer comprises the following raw materials in parts by weight: 85-90 parts of polypropylene, 5-9 parts of ethylene propylene copolymer, 14-18 parts of acrylic acid-acrylamide super absorbent resin and 6-11 parts of inulin; and the skin layer comprises the following raw materials in parts by weight: 80-85 parts of polyethylene, 10-15 parts of methyl methacrylate grafted modified polyethylene, 8-12 parts of ethylene propylene copolymer, 4-7 parts of polyvinyl alcohol, 7-15 parts of superfine pearl powder and 12-17 parts of sodium polyacrylate superabsorbent resin. The skin-friendly low-permeability ES composite short fiber for the hot air non-woven fabric surface layer has the advantages of skin-friendly property, moisture absorption, breathability, elasticity, no irritation to skin, sanitation, antibiosis and the like; and the amount of reverse osmosis after water absorption is small, and the skin-friendly low-permeability ES composite short fiber belongs to the low reverse osmosis type.

Description

Technical field [0001] The invention relates to the field of composite fibers, in particular to a skin-friendly and low-return ES composite short fiber for a hot-air non-woven fabric surface layer and a preparation method thereof. Background technique [0002] Hot-air non-woven fabric belongs to a kind of hot-air bonding (hot-rolled, hot-air) non-woven fabrics. Hot-air non-woven fabrics are used to penetrate the fiber web by hot air on the drying equipment after the fiber is carded, so that it can be heated. Bonded non-woven fabric. [0003] Composite fiber is a differentiated composite fiber, which is composed of two or more fiber-forming polymer melts or concentrated solutions, using the difference in composition, ratio, viscosity, etc., to input the same spinning assembly and input it in the assembly The appropriate parts of the fiber are combined and ejected from the same spinneret hole to produce different types of fibers such as side-by-side, core-spun, sea-island, and sky-s...
