Problems solved by technology

Ordinary band-aids are easy to stick to the wound surface, and the patient is very painful when tearing off the band-aid or changing the dressing. If you don’t pay attention, it will cause new wounds. In addition, scars may be left on the damaged parts where the band-aid has been applied, and the healing effect is not ideal.

Abstract

The invention relates to a manufacturing method for a hydrogel moist dressing band-aid. The band-aid comprises a protective film, an adhesion layer and a fabric layer. The adhesion layer is adhered to the surface of the fabric layer; the protective film is adhered to the adhesion layer; the fabric layer is non-woven hydrogel-compounded moist dressing. The manufacturing method comprises the following steps of: preparing the non-woven hydrogel-compounded moist dressing, coating, drying, rolling, slitting, profiling, shaping and packaging. Non-woven is a thermoplastic polyurethane (TPU) non-woven. The preparation of the non-woven hydrogel-compounded moist dressing comprises the following steps of: firstly, activating the surface of the TPU non-woven by using low-temperature plasma; then, grafting an acryl system high polymer by utilizing an ultraviolet graft polymerization method to finally form the non-woven hydrogel-compounded moist dressing. The manufacturing method for the hydrogel moist dressing band-aid is easy in operation. Moreover, through the band-aid manufactured by the manufacturing method, discomfort caused by dressing change is avoided; the breakage of a wound cannot be scarred and can be healed fast; the infection risk is lowered; and the cost is low.

Description

technical field [0001] The invention relates to a preparation method of a hydrogel moist dressing bandage, which belongs to the technical field of traditional Chinese medicine preparations.
