Medical Protective Clothing Is Divided Into Woven And Non-woven Protective Clothing

Woven materials are mainly used to process reusable medical protective clothing, including traditional woven fabrics, high-density fabrics, coated fabrics and laminated fabrics. Traditional woven fabrics are mainly made of cotton fiber or polyester and other synthetic fibers and cotton blended yarn, which has good comfort and is mainly used for daily work clothes (white coats). High-density fabric is woven with high-count cotton yarn or other superfine synthetic fiber filaments. The yarn gap is very small. It has moisture permeability due to the capillary action of the fiber. It is treated with fluorocarbon, silicone and other water-repellent agents to have a certain degree of resistance. Liquid permeability, mainly used for surgical gown materials that require better waterproof effect. Coating and laminated fabrics are used to enhance the impermeability of materials and are used for protective clothing materials that are used in harsh environments. After the coating process, the surface of the coated fabric is blocked by the coating agent, which has anti-permeability. The hydrophilic group in the coating or the microporous structure formed by a special method can ensure the moisture permeability of the fabric. Laminated fabric is a combination of fabric and a layer of special film (such as microporous film, polyurethane moisture-permeable membrane, etc.) through a lamination process, such as a polytetrafluoroethylene super waterproof and moisture-permeable composite fabric. Since the pore size of the fabric main membrane is much smaller than the diameter of water droplets, it can prevent the penetration of blood, body fluids, etc., and the porosity of the micropores is high. The pore size is larger than the diameter of water vapor molecules, and water vapor molecules can pass freely, so the moisture permeability is better.

Non-woven protective clothing materials are basically disposable. Spunbond nonwovens, spunlace nonwovens, SMS (spunbond-meltblown-spunbond) composite nonwovens, flash evaporation are used more Non-woven fabrics and spunbond laminated products, etc. Generally, non-woven protective clothing has better protection than machine-made materials.
