Textiles have always played a major role in human hygiene. Textiles provide a barrier against all kinds of germs or serve as bandage or plaster… Modern surgery uses textile "stents" and "scaffolds" degradable or not by the human body.

The microbiological testing lab of Centexbel, located in Grâce-Hollogne, near Liege, is fully equipped to assess antibacterial and antifungal properties of (treated) textiles.

The lab also performs tests on biological degradability, barrier properties against micro-organisms, particles, laser rays in operation theatres... and the microbiological hygiene of medical textiles.

Accelarated weathering of plastics

Ultraviolet radiation, temperature, and moisture contribute to material degradation of products exposed to the elements. Accelerated weathering tests simulate these conditions using special environmental chambers and instruments in order to speed up the weathering process and to measure its effects on parts, components, products, and materials.

Barrier properties of textiles

Centexbel has the knowhow and equipment to assess the barrier properties of textiles, surgical gowns, masks and drapes, against microorganisms and blood.

Biological evaluation of medical devices

To assess the health and safety risks linked with the skin contact with medical devices, Centexbel examines their toxic effect on the skin (cytotoxicity, irritation, sensitivity,…) according to ISO 10993-5 “Biological evaluation of medical devices – part 5 - cytotoxicity : in vitro methods”

Burning behaviour of PPE

Assessments of the resistance of PPE to heat, fire, splashes of molten metal

Capillary rheometry

Capillary rheometers principle is based on measurement of the melt flow, by a pressure applied through the precisely dimensioned capillary.

Cell toxicity (cytotoxicity)

An increasing number and variety of functionalised textiles (perfumed, FR, stain-repellent, waterproof, antibacterial, slimming, anti-UV…) are being marketed. It is essential that these textiles are harmless. It is therefore advisable to check the tissue compatibility of finished textile materials and to verify whether new chemical substances used to functionalise textiles do not involve any risks to the skin (cytotoxicity, irritation, …).

Charpy & Izod Impact tests

There are two types of test use for testing the Impact resistance of any material one is Izod Impact resistance test and other is Charpy Impact resistance test. Both of them use the same principle to test the Impact resistance of any material but still there are may difference in them and our today's article will show these difference between Izod and Charpy Impact testing

Chemical safety of textiles and plastics

The globalisation of the textile and plastic converting industry makes it increasingly difficult and complex to control the production flow and to exactly know the products (chemicals) that have been used. Morevover, consumers and their organisations want to be informed about the composition of the products they buy and demand that they do not contain harmful substances.
