Cleanroom clothing is available for any type of cleanroom. The main reason for wearing cleanroom garments is to protect your skin and cover your street clothes to decrease the risk of lint, shedding skin cells, hair and other bodily products in the critical environment, with different materials having different cleanliness levels. So when you’re deciding on which cleanroom apparel you’ll need, there are different matters to consider.
Construction of all cleanroom apparel must be performed using silicone-free thread in a silicone-free environment. There are three different types of materials that are used to make cleanroom garments, Tyvek, microporous and polypropylene:
- Tyvek – this is the cleanest material you can use and is usually preferred because of its lightweight and breathability and premium protection against liquid and dry particals. However, there are high-quality, disposable alternatives to Tyvek.
- Microporous – Often used in laboratories that facilitate contaminant-free exchanges, this material contains pores that are less than 2 nm in diameter. This is a strong, superior quality garment manufactured from breathable liquid resistant material.
- Polypropylene – This type of cleanroom material is considered the least clean. It’s usually a coating that is placed on top of disposable cleanroom garments.
When deciding on your cleanroom coveralls, you can choose between reusable or disposable garments. You can base this decision on different factors:
- The product being manufactured
- The process you’ll be using during manufacturing
- Whether or not your cleanroom will have laundry service available for the reusable garments
- And the number of garments that will be required during manufacturing
For safety and cleanliness, there are a number of tests performed on disposable cleanroom apparel. The tests are similar to the tests that are performed on all reusable fabrics that are manufactured worldwide. They are tested by:
- Grab tensile
- Air permeability
- Pore size
- Surface resistivity
- Static decay
- And bacterial filtration efficiency
Before deciding, you’ll need to determine the class of the cleanroom, which materials best suit you and your manufacturing needs and if you prefer reusable or disposable cleanroom apparel.
