METHOD FOR MANUFACTURING SHEET HAVING POLYURETHANE FOAM/HYDROFIBER COMPOSITE AND WOUND DRESSING MATERIAL MANUFACTURED THEREFROM

摘要

An objective of the present invention is to solve a problem of a conventionally used wound dressing material. Most of foam dressing materials and hydrogel as a conventionally used wound dressing material has a problem that the dressing materials and the hydrogel maintain only a wet state or are dissolved by exudation and the like to leave a residue stuck on a wound portion and thus, secondary washing of the wound portion is required. Moreover, the foam dressing material is made of urethane and the like such that it is difficult to assign a material capable of promoting the cure of a wound or antibacterial property. Moreover, in the case of the hydrogel, it is difficult to assign antibacterial property due to a process. Moreover, the urethane foam dressing agent has disadvantages of low absorptiveness and weak mechanical strength such as tearing strength. To solve such problems, polyurethane foam and hydrofiber are mixed as a wound dressing material used for treating a wound. According to the present invention, the method comprises the steps of: manufacturing hydrofiber non-woven fabric; manufacturing a pore-less film (skin); and forming polyurethane foam.;COPYRIGHT KIPO 2020
