Embodiment

[0012] The production method of the non-woven fabric for wound binding of this embodiment includes the following production steps:

[0013] 1. Configure antibacterial finishing solution, mix water, granular water-soluble chitosan and granular calcium alginate at room temperature, and stir evenly to make antibacterial finishing solution, the concentration of chitosan is 3%, the concentration of calcium alginate The concentration is 0.05%;

[0014] 2. Non-woven fabric finishing, put the non-woven fabric into the prepared antibacterial finishing liquid in step 1, soak and finish, the mass ratio of the antibacterial finishing liquid to the non-woven fabric is 2:1, first put the non-woven fabric into the finishing liquid Stir in medium for 20 minutes, then soak for 30 minutes, then dehydrate and dry;

[0015] 3. The processed non-woven fabric is shaped at high temperature and then compounded with the thermoplastic polyurethane TPU film at high temperature.

[0016] The TPU film has a ...

Abstract

The present invention discloses a production method of a non-woven fabric for wound dressing. The production method comprises: mixing water, granular water-soluble chitosan and granular calcium alginate at a room temperature, and uniformly stirring to prepare an antibacterial finishing solution, wherein the concentration of the chitosan is 1-3%, and the concentration of the calcium alginate is 0.02-0.05%; placing a non-woven fabric into the blended antibacterial finishing solution, soaking, finishing, dewatering, and drying; and carrying out high temperature shaping on the treated non-woven fabric, and carrying out high temperature compounding on the shaped non-woven fabric and a thermoplastic polyurethane TPU film. According to the present invention, the non-woven fabric is preferably selected, is a non-woven cloth, and has characteristics of softness, air permeability, no fiber tow production, and assurance of fresh and health wound; the finishing solution is adopted to carry out the soaking treatment, such that the original softness of the non-woven fabric can not be damaged, the functions of bacterial killing, bacterial inhibiting, inflammation eliminating and hemostasis are provided for the non-woven fabric, and the wound can be easily and rapidly healed; and the thermoplastic polyurethane TPU film has a good water resistance and moisture permeability performance.

Description

Technical field [0001] The invention belongs to the technical field of fabrics, and specifically relates to a production method of a non-woven fabric used for wound dressing. Background technique [0002] Bandaging is one of the important measures for emergency treatment of trauma. Timely and correct dressing can achieve compression and hemostasis, reduce infection, protect wounds, reduce pain, and fix dressings and splints; on the contrary, wrong dressing can lead to increased bleeding, aggravate infection, cause new injuries, and leave sequelae. . The dressing cloth will directly affect the dressing effect and wound healing, so the selection of the dressing cloth is very important. Summary of the invention [0003] In order to overcome the above-mentioned technical problems in the prior art, the purpose of the present invention is to provide a method for producing a non-woven fabric for wound wrapping. The method is reasonable, and the fabric obtained has good air permeability...
