Disposable Isolation Gowns: Disposable Isolation Gowns are usually made of non-woven materials, or combined with materials with better impermeability properties such as plastic films. It is imparted with integrity and toughness through the use of various nonwoven fiber joining techniques rather than the geometrical interlocking of woven and knitted materials. Isolation gowns should cover the torso and all clothing to form a physical barrier to the spread of microorganisms and other substances. It should be impermeable, abrasion resistant and tear resistant. At present, there is no special standard in China.

There is only a brief introduction on the putting on and taking off of the isolation gown in the "Isolation Technical Specification" (the isolation gown should be opened at the back and can cover all the clothes and exposed skin), but there is no information on the specifications and materials, etc. related indicators. Isolation gowns can be reusable or disposable without a cap. Judging from the definition of isolation gowns in the "Technical Specifications for Isolation in Hospitals", there is no requirement for anti-penetration, and isolation gowns can be waterproof or not.
Disposable protective clothing: The protective clothing consists of a hooded top and pants. It can be divided into one-piece structure and split structure. The trouser legs and cuffs are tightened, and the protection level of protective clothing is higher than that of isolation clothing. One-time use is generally recommended. The standard clearly states that protective clothing must have liquid barrier functions (water permeability, moisture permeability, resistance to synthetic blood penetration, surface moisture resistance), flame retardant properties and antistatic properties. Efficiency, etc. are required.
Disposable surgical gown (sterile): The standard has clear requirements for the barrier properties, strength, microbial penetration, comfort, etc. of surgical gown materials. Disposable surgical gown (sterile) should be impermeable, sterile, one-piece, without cap. Generally, the cuff of the surgical gown is elastic, which is easy to wear, and it is beneficial to wear sterile hand gloves. It is not only used to protect medical staff from contamination by infectious substances, but also to protect the sterile state of surgically exposed parts.
