Embodiment 1

[0016] A highly air-permeable nonwoven fabric for medical protective clothing, the raw materials of which include by weight: 40 parts of acrylic fiber, 34 parts of polyacrylonitrile fiber, 8.5 parts of cellulose ester fiber, 27 parts of elastic fiber, and 4 parts of viscose fiber , 12 parts of additives, 1 part of chrysotile.

Embodiment 2

[0018] A highly air-permeable nonwoven fabric for medical protective clothing, the raw materials of which include by weight: 55 parts of acrylic fiber, 22 parts of polyacrylonitrile fiber, 13 parts of cellulose ester fiber, 18 parts of elastic fiber, and 8 parts of viscose fiber , 6 parts of additives, 3 parts of chrysotile;

[0019] Wherein, the additive is prepared according to the following process: the nano-calcium carbonate is placed in a high-speed mixing device with an atomizing injection device and a heating device, the temperature is raised, and the sericin aqueous solution is uniformly sprayed on the surface of the nano-calcium carbonate to obtain the additive.

Embodiment 3

[0021] A highly air-permeable nonwoven fabric for medical protective clothing, the raw materials of which include by weight: 45 parts of acrylic fiber, 28 parts of polyacrylonitrile fiber, 10 parts of cellulose ester fiber, 22 parts of elastic fiber, and 6 parts of viscose fiber , 8 parts of additives, 2 parts of chrysotile;

[0022] Wherein, the additive is prepared according to the following process: the nano-calcium carbonate is placed in a high-speed mixing device with an atomizing spray device and a heating device, the temperature is raised, and the sericin aqueous solution is evenly sprayed onto the surface of the nano-calcium carbonate to obtain the additive;

[0023] Before preparing the additive, the nano-calcium carbonate is dried so that the mass fraction of its moisture is below 0.2%;

[0024] Said heating up is heating up to 95°C;

[0025] The weight ratio of the nano-calcium carbonate to the sericin aqueous solution is 1.5:4;

[0026] The mass fraction of the s...

Abstract

The invention discloses a high-breathability non-woven fabric for medical protective clothing. The high-breathability non-woven fabric for the medical protective clothing comprises the following raw materials in parts by weight: 40-55 parts of acrylic fibers, 22-34 parts of polyacrylonitrile fibers, 8.5-13 parts of cellulose ester fibers, 18-27 parts of elastic fibers, 4-8 parts of viscose fibers,6-12 parts of an additive and 1-3 parts of chrysotile. The high-breathability non-woven fabric for the medical protective clothing has excellent breathability.

Description

technical field [0001] The invention relates to a nonwoven fabric, in particular to a highly air-permeable nonwoven fabric used for medical protective clothing. Background technique [0002] Medical protective clothing has good moisture permeability and barrier properties, and can effectively resist the penetration of alcohol, blood, body fluids, air dust particles, and bacteria. It is safe and convenient to use, and can effectively protect the wearer from the threat of infection. It is comfortable to wear and feels good. , Strong tensile strength, breathable and waterproof, no cross-infection, etc. The protective clothing is a one-piece structure consisting of a hat, jacket, and trousers; the structure is reasonable, easy to wear, and the joint is tight; the cuffs, ankles, and the face of the hat are closed with elastic elastic bands. [0003] The air permeability of the existing non-woven medical protective clothing is not high, and it is difficult to meet the needs of th...
