简体中文As a type of chemical protective clothing, medical protective clothing is mainly used for medical staff to wear. It not only needs to drain moisture and breathe, and wear freely, but also protect medical staff from various pollutants such as viruses and bacteria during diagnosis and treatment. Resist the intrusion of water, alcohol, and oil stains, and must be effective antistatic, and even prevent dust from entering.
It is required to achieve "three rejections and one resistance", that is, water-repellent, blood-repellent, alcohol-repellent, and anti-static medical protective clothing, which is different from general weaving materials and uses micro-nano-level materials. This composite material can be combined by different materials, such as polyethylene/polypropylene spunbonded nonwoven fabric, combined with breathable microporous film or other nonwoven fabric, or spunlace nonwoven fabric combined with breathable microporous film, or Wooden paddle composite spunlace non-woven fabric.
The nonwoven materials used in several medical protective clothing currently being sold and developed in the domestic market mainly include the following:
Polypropylene Spunbond Fabric
Polyester fiber and wood pulp composite spunlace cloth
Polypropylene spunbond-meltblown-spunbond composite nonwoven fabric, namely SMS or SMMS
Polymer coated fabric
Polyethylene breathable film/non-woven composite fabric
How is it made?
Common medical protective clothing usually consists of a one-piece structure consisting of a hat, a jacket, and trousers. There are strict standards in the production, including protection (tightness), wearability, safety and hygiene. The medical protective clothing that can be made by cutting, stitching, tightening, and bonding adhesive strips is inseparable from the three types of machines involved: flat seam, overlock seam, and pressure glue.
Whether it is the production of ordinary clothing or protective clothing, almost all stitching is inseparable from the sewing machine. Although it is a "basic worker", its function should not be underestimated. The tightness of the thread and the stitch length The degree of detail is related to the final effect. It can meet the sewing, zipper, Velcro, elastic and other processes in protective clothing.
Medical protective clothing usually adopts a closed placket design, that is, the inner zipper is closed, the outer placket is glued, and the zipper and velcro are attached through the flat seam. In addition to better putting on and taking off, this design can make the fit tighter. There are elastic bands on the cuffs, ankles, and hats.
The reason why protective clothing can achieve such a high degree of airtightness, in addition to the above designs, is inseparable from this most important step. After the lathe has sewn the protective clothing, all stitches and pinholes in the protective clothing need to be glued and sealed by a press machine to prevent dust or liquid from entering the sewing pinholes and enhance the isolation performance and use of the protective clothing Safety
