Problems solved by technology

[0004] In view of the related technologies mentioned above, the inventor believes that it has the following defects: when the surgical gown made of multi-layer composite non-woven material is to cover most of the human body, the operator will sweat during the operation. The air permeability of the surgical gown is poor, resulting in poor air permeability and comfort of the surgical gown, which will affect the surgical quality of the surgical staff

Embodiment 1

[0048] A waterproof and breathable surgical gown material, the preparation steps are as follows:

[0049] S1: Preparation of base layer: blend soybean protein fiber and flax fiber, and use Meyer-4-11.6QC double-sided knitting circular knitting machine, machine size 26#, 18G gauge, and cylinder diameter of 34 inches. Floor;

[0050] Preparation of functional layer: First, add microporous lignocellulose powder and antibacterial agent to the coating agent and mix and stir to obtain a coating. The plain film is calendered, and then the coating material is evenly coated on the surface of the calendered cellulose acetate film, and the functional layer is obtained after drying at 80 °C;

[0051] S2: Coat the mesh-like adhesive evenly on the surface of the base layer, and use the mesh-like adhesive to hot-press the functional layer on one side of the base layer. The pressure is 5Mpa, the temperature is 180°C, and the time is 120min for pressing to obtain a waterproof and breathable ...

Embodiment 2-3

[0054] A preparation method of a waterproof and breathable surgical gown material is different from Example 1 in that the components of the raw materials and their corresponding weights are shown in Table 2.

[0055] Each raw material and its weight (kg) in the embodiment 1-3 of table 2

[0056] component Example 1 Example 2 Example 3 soy protein fiber 40 45 50 flax fiber 60 55 50 Cellulose acetate film 25 35 45 coating agent 30 35 40 Microporous lignocellulose powder 15 13 10 omentum adhesive 20 17 15 Antibacterial agents 5 4 3

Embodiment 4

[0058] A preparation method of a waterproof and breathable surgical gown material, the difference from Example 1 is that the raw material of the waterproof and breathable material also includes 10kg trifluoropropyl methyl silicone oil, and in the preparation of the functional layer: the microporous lignocellulose powder , antibacterial agent and trifluoropropyl methyl silicone oil are added to the coating agent, mixed and stirred evenly to obtain the coating. At the same time, the cellulose acetate film is calendered with a pendulum calender at a rolling temperature of 60 °C. , and then the coating material is evenly coated on the surface of the calendered cellulose acetate film, and dried at 80° C. to obtain a functional layer.

Abstract

The invention relates to the field of operating gowns, and particularly discloses a waterproof and breathable operating gown material, a preparation method thereof and an operating gown. The waterproof and breathable operating gown material comprises the following raw materials: 40-50 parts of soybean protein fibers; 50 to 60 parts of linen fiber; 25-45 parts of a cellulose acetate membrane; 30 to 40 parts of a coating agent; 10 to 15 parts of microporous lignocellulose micro powder; 15 to 20 parts of a net film type adhesive; and 3-5 parts of an antibacterial agent. The preparation method comprises the following steps: S1, blending the soybean protein fibers and the linen fibers to obtain the base layer; the preparation method comprises the following steps: adding microporous lignocellulose micro powder and an antibacterial agent into a coating agent, calendaring a cellulose acetate membrane, coating the surface of the calendaring cellulose acetate membrane with a coating material, and drying to obtain a functional layer; and S2, uniformly laying the net film-shaped adhesive on the surface of the base layer, and compounding the functional layer on one side of the base layer through hot pressing to obtain the waterproof and breathable operating coat material. The fabric has the advantage of good air permeability.

Description

technical field [0001] The present application relates to the field of surgical gowns, and more particularly, to a waterproof and breathable surgical gown material, a preparation method thereof, and a surgical gown. Background technique [0002] As a necessary protective clothing during surgery, surgical gowns are sterile isolation gowns worn by medical staff during operations, experiments and research. They are used to isolate pathogenic microorganisms and prevent blood and other liquids from infecting medical staff. They are mainly used for medical surgical operations, virus Disinfection in contaminated areas, etc. It is used to reduce the risk of medical personnel being exposed to pathogenic microorganisms, and at the same time, it can also reduce the risk of mutual transmission of pathogenic microorganisms between medical personnel and patients. It is a safety barrier for sterile areas in surgical operations. [0003] The Chinese invention patent with the application nu...
