Test area

Textiles and clothing

One of the most extensive areas in our test laboratory is the examination of textile and clothing articles as well as textile products of all kinds.

Materials are tested for their mechanical-technological and chemical-analytical properties using a variety of different measuring procedures and test methods. In doing so, it is possible to determine requirements for the general use of the products and their quality, or to draw conclusions about the presence of substances that are harmful to health.

Here, the majority of all manufacturers and importers have defined their own strict criteria in order to protect the consumer. In addition, legal regulations apply to various harmful substances. Detailed customer advice and support are an integral part of our service.

We prepare individual offers and test reports.

Textile accessories

It is not only the main material that should meet the highest requirements, but also various accessories are more and more in the focus of legal and commercial regulations. A full inspection including all possible accessories is as natural to us as the individual inspection of a single component, no matter how insignificant it may seem.

  • Buttons

  • Zips

  • Labels

  • Tags

  • Cords and ribbons

  • Rivets

Testing examples

  • Zip strengths

  • Opening forces of press studs

  • Chromium VI content

  • Extractable heavy metals

  • Corrosion
