Chemicals are essential in the textile and plastic converting industry. Therefore it is equally essential to exactly know the chemical composition of your products not only to optimize them but also because some chemicals may have harmful effects on human health and on the environment and need to be detected, limited and in some cases even prohibited according to legal reglementations or ecolabel related criteria.

The elaborated textile-related knowledge of Centexbel allows us to assist the textile industry in a most effective way to identify and quantify all chemical substances in textiles and plastics, to solve any problem, to interprete test results, to obtain labels and to comply with legal requirements.

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.

Antibacterial efficiency

Resistance to bacterial growth

Antifungal efficiency

Determination of the Antimycotic Activity - Agar Diffusion Plate Test

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.

Carpet classification

European standard EN 1307 specifies the requirements for classification, domestic or commercial, of all carpets and carpet tiles, excluding rugs and runners into use classes. EN 1307 is linked to EN ISO 10874:2012, which is a classification system for resilient, textile and laminate floor coverings. The classification is based on practical requirements for areas of use and intensity of use.

Carpet wear - changes in appearance

Testing and evaluation of changes in appearance by means of Vetterman drum and hexapod tumbler tester

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
