Description

Technical Field

[0001] The invention relates to isolation suit production equipment. Background Art

[0002] Non-woven medical protective clothing is a sterile isolation suit worn during surgery, testing, and scientific research. It is used to isolate infections caused by pathogens and other factors to prevent secondary infections in patients. It is mainly used for medical operations, hospital treatment, epidemic prevention inspections in public places, and disinfection of virus-contaminated areas. Protective clothing consists of a top, pants, and sleeves. Traditional protective clothing is processed by manual sewing. The top, pants, and sleeves are sewn separately and then spliced ​​together.
