The role of protective coverall is to improve the hygienic environment of the treatment area and prevent bacterial penetration and therefore cross infection of viruses and bacteria. Protective coverall is not only used in hospitals, but also widely used in emergency stations, private clinics, disability centers, nursing homes and independent laboratories.

What are protective coverall?

Protective coverall refers to protective clothing used by medical personnel (doctors, nurses, public health personnel, cleaning staff, etc.) and people entering specific medical and health areas (such as patients, hospital visitors, personnel entering infected areas, etc.). Its role is to isolate bacteria, harmful ultra-fine dust, acid and alkali solutions, electromagnetic radiation, etc., to ensure the safety of personnel and keep the environment clean.


What protective coverall are made of ?

According to different materials processing technology, protective coverall is divided into woven and non-woven protective clothing.

Woven materials are mainly used to process reusable protective coverall, 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 yarns, which have good comfort and are mainly used in daily work clothes (white coats). High-density fabrics are made of high-count cotton yarns or other ultra-fine synthetic fiber filaments. The yarn gap is very small. Because of the capillary action of the fibers, they have moisture permeability. Liquid permeability is mainly used for surgical gown materials that need better waterproof effect. Coated and laminated fabrics are used to enhance the material's permeability resistance and are used in protective clothing materials in harsh environments. The coated fabric is processed by coating, the surface is closed by the coating agent, and has the permeability resistance. The hydrophilic groups in the coating or the microporous structure formed by special methods ensure the fabric's moisture permeability. Laminated fabric is a composite of a fabric and a layer of special film (such as a microporous film, a polyurethane moisture-permeable film, etc.) through a lamination process, such as a polytetrafluoroethylene super waterproof and moisture-permeable composite fabric. Because the pore diameter of the microporous membrane of the fabric is much smaller than the diameter of water droplets, it can prevent the penetration of blood, body fluids, etc. The high porosity of the micropores 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 non-wovens, spunlace non-wovens, SMS (spunbond-meltblown-spunbond) composite non-wovens, and flash evaporation methods are commonly used. Non-woven fabrics and spunbond fabric lamination products. Generally, non-woven protective clothing has better protection than mechanical materials.


Special protective coverall

 Chemical protective clothing

            Chemical protective clothing is protective clothing worn to protect yourself from chemically hazardous or corrosive substances when handling hazardous medical chemicals. In addition to the chemical protection of clothing materials, chemical protective clothing has stricter requirements on tightness and the seam structure of clothing.

   Electromagnetic radiation protective clothing

            Electromagnetic radiation protective clothing is a protective coverall that implants extremely fine conductive fibers in the fabric material, so that the protective clothing does not generate static electricity and can shield electromagnetic waves in the range of 100kHz to 300GHz. It is mainly used for operating people of electronic medical equipment systems in hospitals.

  Nuclear and radiation protective clothing

            It is used in nuclear radiation environment (small-dose, large-scale ionizing radiation, mainly α, β-rays), to prevent radio aerosol and dust from invading the human body. It has the functions of protecting radioactive aerosols, protecting more than 150 kinds of toxic and corrosive gases, liquids and solids, protecting potential radioactive particles and liquids from entering the body, and 100% blocking dry particles of more than 0.2μm.
