Problems solved by technology

[0002] Medical dressings are medical materials used to cover wounds or other damages. The traditional way to deal with wounds is mainly to cover them with gauze to absorb the exudate of the wound surface and prevent the intrusion of dirt from causing infection. However, this method cannot moisturize and Adhesive wound surface, it is easy to damage the wound again when changing, causing severe pain
There are some dressings made with new materials and new methods, but none of them use all-natural absorbable materials that are safe and reliable

Abstract

The invention relates to an alginate fiber absorbable medical auxiliary material and a manufacture technology of the alginate fiber absorbable medical auxiliary material, belonging to the field of medical accessory. The alginate fiber absorbable medical auxiliary material is characterized by being formed by blending and needling alginate fiber and polylactic acid fiber; the fabric includes the following raw materials by weight: 70-100% of alginate fiber, and 0-30% of polylactic acid fiber. The alginate fiber absorbable medical auxiliary material and the manufacture technology provided by the invention are good in relation to skin, and are bacteriostatic, have functions of humidity absorbing and ventilating, and are safe and environment-friendly.

Description

technical field [0001] The invention relates to a seaweed fiber absorbable medical auxiliary material and a manufacturing process thereof, belonging to the field of medical auxiliary materials. Background technique [0002] Medical dressings are medical materials used to cover wounds or other damages. The traditional way to deal with wounds is mainly to cover them with gauze to absorb the exudate of the wound surface and prevent the intrusion of dirt from causing infection. However, this method cannot moisturize and Adhesive wound surface is easy to damage the wound again when changing, causing severe pain. There are some dressings made with new materials and new methods, but none of them use a purely natural absorbable material that is safe and reliable. Contents of the invention [0003] The present invention provides a seaweed polylactic acid absorbable medical auxiliary material that is skin-friendly, antibacterial, moisture-absorbing, breathable, safe and environment...
