Cleanroom undergarments

Interesting facts

Cleanroom undergarments are made of abrasion-resistant, synthetic materials compared to ordinary streetwear. This prevents large quantities of particles from entering the cleanroom uncontrolled by diffusion, migration or due to the overpressure under the cleanroom garments.

Functionality combined with design

Cleanroom suitable undergarments which can also be worn at any time outside of the cleanroom!

The particular efficiency of cleanroom undergarments has been proven in various measurements, amongst other at the DITF Denkendorf (see Study 2).

In addition to this aspect, use of cleanroom undergarments can also improve the wearing comfort of the complete garment system and in this way can improve the acceptance of the employees.

A variety of fabrics are available for our cleanroom undergarments.

Efficiency of cleanroom compatible undergarments

To reduce the particle emission of a human being in a cleanroom, it is necessary to wear suitable clothing beneath the coverall or lab coat. These cleanroom compatible undergarments are worn on top of the personal underwear. It is important that these undergarments have no negative impact on the wearing comfort (see Study) and also that no additional particles are generated. Therefore, as with the cleanroom garments, the textile is to be manufactured from synthetic continuous filaments and not from short staple fibres.

Wearing comfort

Polyester was accepted for a long time as uncomfortable because the surface touch was perceived as particularly unpleasant and transpiration appeared to be unavoidable. This has changed noticeably in the last few years. Functional garments, especially in sportswear applications, have proven that synthetic textiles can be superior in many ways to natural fibres.

The textiles used by Dastex profit in a lot of cases from these new, positive wearing comfort features.

In general the use of cleanroom compatible undergarments for all applications in all cleanroom zones is to be recommended.
