Problems solved by technology

[0006] In order to make up for the deficiencies in the prior art, the invention proposes a method for preparing medical sanitary nonwoven fabrics. The present invention is mainly used to solve the problem that most of the current medical sanitary nonwoven fabrics exist in the form of nonwoven fabrics Relatively simple, when the patient's wound is slightly large, the medical properties of the non-woven fabric itself cannot quickly stop bleeding and sterilize the wound, thereby increasing the patient's bleeding rate and the probability of fungal infection. At the same time, some medical The permeability effect of sanitary non-woven fabrics is poor, which will reduce the air flow in the non-woven fabrics, thereby slowing down the healing effect of the wound. Poor ability to stop bleeding

preparation example Construction

[0036] The preparation method of medical sanitary nonwoven fabric comprises the following steps:

[0037] S1: Firstly, the polyester and viscose fibers in the above raw materials are mixed. After the raw materials are mixed, the raw materials are extruded and melted. After the extrusion and melted, the raw materials are injected into the spinning equipment for spinning treatment. Cloths of different sizes are ready for use; by using the cloths made of the above raw materials, the prepared cloths can be made to have a skin-friendly effect, thereby preventing the cloths from polluting the skin wounds, and at the same time, the cloths are relatively soft and non-toxic scratches the skin;

[0038] S2: Put the pure water in the raw material into the reaction kettle and heat it to 25-30°C. After heating the pure water, put the plant essence extract, chitosan, nano-silver, hyaluronic acid and calcium alginate in the raw material in sequence. Put them into the reaction kettle for mix...

Embodiment approach

[0041] As an embodiment of the present invention, the raw materials also include polyvinylpyrrolidone and amino-terminated polyethylene glycol;

[0042] The polyvinylpyrrolidone used in the raw material is a kind of medicinal material, and has strong binding ability, can exist in the mode of binding agent in the present invention, also has strong stability and lubricity simultaneously, thus prevents The prepared dressing is easy to react with other substances to reduce the medical effect. At the same time, polyvinylpyrrolidone can also be combined with the dopamine mixture in the raw material to form a strong hydrogen bond, which can improve the firmness of the non-woven coating At the same time, polyvinylpyrrolidone can also complex with the iodine element in the raw material, thereby introducing the bactericidal group of the iodine element, and constructing a non-woven surface with anti-fouling and bactericidal synergistic effects. The amino-terminated polyethylene glycol ca...

Abstract

The invention belongs to the technical field of a sanitary nonwoven fabric for medical use, and particularly relates to a preparation method of a sanitary nonwoven fabric for medical use. The sanitarynonwoven fabric for medical use comprises a protection layer and a dressing layer, wherein the inside of the protection layer is under an aseptic condition, and is obtained by being soaked in an antibacterial disinfectant; gelatin layers in uniform arrangement are fixedly connected to positions of two sides of the protection layer; and a slide groove is formed in an inner wall of the protection layer. The preparation method of the sanitary nonwoven fabric for medical use provided by the invention is mainly used for solving the problems that existing sanitary nonwoven fabrics for medical use mostly exist in a nonwoven fabric form, the structure is single, and if the wound of a patient is bigger, the hemostasis and sterilization on the wound cannot be fast realized by the medicine properties of the nonwoven fabric per se, so that the bleeding rate and the fungal infection probability of the patient are increased; meanwhile, some sanitary nonwoven fabrics for medical use have poor breathing effects, and air flowing inside the nonwoven fabrics can be reduced, so that the wound healing effect is decelerated; and although some nonwoven fabrics have good breathing effect, the hemostasiscapability of the nonwoven fabric on the wound is poor.

Description

technical field [0001] The invention belongs to the technical field of medical sanitary nonwoven fabrics, in particular to a preparation method of medical sanitary nonwoven fabrics. Background technique [0002] Non-woven fabric, also called non-woven fabric, is a kind of wet or dry paper machine, which is prepared from chemical fibers and plant fibers with water or air as the suspension medium. Although it is cloth without spinning, it is called non-woven fabric. During manufacture, the short textile fibers or filaments are oriented or randomly arranged to form a web structure, and then reinforced by mechanical, thermal bonding or chemical methods. Non-woven fabric is a new generation of environmentally friendly materials, with the characteristics of moisture-proof, breathable, environmentally friendly, low production cost, easy to decompose, non-toxic and non-irritating, and recyclable. Most of the raw materials for making non-woven fabrics are polypropylene, which is di...
