Cleanroom socks

Material selection

Increasingly, there are specifications, such as Annex 1 of the European GMP guidelines, for the use of cleanroom suitable socks, especially in aseptic areas. Both disposable socks and washable synthetic reusable models are used there.

Natural fibres are unsuitable due to their abrasion and the risk of fibre breaks. Synthetic materials, however, have clear advantages. As far as wearing comfort is concerned, the fit and thus the wearing sensation can be improved by using special synthetic fibres with high elasticity.  Cleanroom socks with silver fibres or fibres with embedded silver ions also have antimicrobial properties and improve the electrostatic properties.

Disposable or reusable socks?

The logistical effort is significantly lower with the one-way solution. Furthermore, you avoid the problem of having to personalise washed socks in order to assign them to their wearers. The disadvantages, on the other hand, are a poorer fit, since disposable socks are usually only available in universal sizes, and in the long term a higher cost factor and increased waste.

Most important advantage of reusable socks: Properly decontaminated, they are usually much less contaminated with particles than disposable items when delivered.

Necessary basic requirements for cleanroom-suitable socks, depending on the respective application:

  • abrasion-resistant material (synthetic)
  • conductivity, ESD-compliant if required
  • washability
  • sterilisability, for use in microbiological monitored areas
Reusable sock made of recycled material, Art.-No. 39392-REC

Be sure to select reusable socks one size larger.

Due to their material properties, cleanroom socks shrink significantly more during the washing process.
