Guiding hygroscopic hydro-entangled non-woven fabric used for surgical blood vessel operation

Abstract

The invention relates to a type of guiding hygroscopic hydro-entangled non-woven fabric used for surgical blood vessel operation, belonging to the weaving material technical field, and the guiding hygroscopic hydro-entangled non-woven fabric comprises a surface layer made of pearl line non-woven fabric, an interface layer made of plastic film, and a bottom layer made of spunbonded non-woven fabric, combined via hot rolling and bonding, wherein the upper layer fibre web of the pearl line non-woven fabric, directly in contact with patients, adopts the straight-paving technology, with weight accounting for two thirds of the surface non-woven fabric grammage; the lower layer fibre web adopts cross lapping technology, with weight accounting for one third of the surface non-woven fabric grammage; and the upper layer fibre web and the lower layer fibre web form the surface layer via hydro-entangled method. The guiding hygroscopic hydro-entangled non-woven fabric of the invention features thinness, high hygroscopicity, excellent diversion performance, and great antibiosis function. Moreover, the guiding hygroscopic hydro-entangled non-woven fabric has no fluff, is lint-free, and does not stick to the wound.

Description

technical field [0001] The invention relates to a medical spunlace nonwoven material for guiding hygroscopic surgical blood vessel operations, belonging to the technical field of textile materials. Background technique Spunlaced nonwovens are mainly used in medical treatment to be processed into surgical gowns, surgical drapes, surgical drapes, wound dressings, bandages, tourniquets and other products. Medical products are in direct contact with patients' wounds or affected areas, requiring them to have good absorption properties (liquid absorption, blood absorption, hemostasis, etc.), non-toxicity, good affinity with wounds, and functions that are conducive to wound healing. At present, there are still some problems in the promotion of spunlace medical dressing products, such as too thick thickness, fuzzing, adhesion between cloth and cloth, poor uniformity of cloth surface, failure to meet pharmacological indicators, and poor wet strength. Contents of the invention I...
