Intermediate garments

Interesting facts about textile intermediate garments

Cleanroom intermediate clothing is 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 outerwear.

Functionality combined with design

A cleanroom suitable intermediate garment which can also be worn at any time outside of the cleanroom!

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

In addition to this facet, use of cleanroom intermediate garments can also improve the wear 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 intermediate garments.

Efficiency of a cleanroom compatible intermediate garment

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 intermediate garments are worn on top of the personal underwear. It is important that these intermediate garments have no negative impact on the wear comfort (see Study) and also that no additional particles are generated. Therefore, as with the outerwear, the textile is to be manufactured from synthetic continuous filaments and not from short staple fibres.

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 wear comfort features.

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