Description

TECHNICAL FIELD

[0001] The utility model relates to non -woven fabric processing technical field, concretely is a kind of TPU elastic non -woven fabric processing and dust sterilization device. BACKGROUND

[0002] Thermoplastic polyurethane elastomer is also called thermoplastic polyurethane rubber, and is abbreviated as TPU. It is a (AB) n type block linear polymer. A is a polyester or polyether with a high molecular weight (1000-6000). B is a diol containing 2-12 straight-chain carbon atoms. The chemical structure between AB segments is diisocyanate. Thermoplastic polyurethane rubber is crosslinked by intermolecular hydrogen bonds or slightly crosslinked between macromolecular chains. With the increase or decrease of temperature, these two crosslinked structures are reversible. In the molten state or solution state, the intermolecular force is weakened, and after cooling or solvent evaporation, the strong intermolecular force connects together to restore the original solid properties. Typical TPU such as spandex, etc. Elastic non-woven fabric is a kind of non-woven fabric. Non-woven fabric is widely used in medical, chemical, printing, automobile, building material, furniture and other industries due to its moisture-proof, breathable, flexible, light weight, non-combustible, easy to decompose, non-toxic and non-irritating, rich color, low price, recyclable and other characteristics.
