Problems solved by technology

[0002] Medical hemostatic material is an important commonly used medical dressing, which has the characteristics of large amount of use and wide application. However, conventional hemostatic gauze will cause problems such as changing dressings, aggravating the pain of patients, and environmental pollution of discarded gauze, and medical gauze is often used When exposed to the outside, various harmful bacteria will inevitably adhere to it, so when people use gauze, their hands will be contaminated with many harmful bacteria. Good antibacterial and anti-adhesive properties, so we propose a method for making a soluble hemostatic textile material

Abstract

The invention discloses a preparation method of a soluble hemostatic textile material, and belongs to the technical field of preparation of soluble hemostatic textile materials. The preparation methodcomprises the steps of firstly, preparing spinning raw pulp fibers and antibacterial liquid; then preparing a fiber membrane, and preparing antibacterial fibers on the basis of the fiber membrane; and finally, treating the antibacterial fibers with 4 mol / L of a chloroacetic acid reaction solution, adjusting pH to be neutral with a hydrochloric acid solution and finally washing with deionized water to obtain the soluble hemostatic textile material for a hemostatic gauze. The gauze can be well adhered to a wound, and the comfort of the hemostatic gauze in use is improved. The prepared fibers have excellent antibacterial and deodorizing properties, and also have good air permeability and water absorption. The solubility of the fiber material is improved, and meanwhile, the textile material has a hemostatic function. Wound healing is promoted, adhesion is avoided, and protection to the wound is improved.
