Foto van de maand
Wij willen ze graag met u delen en kiezen daarom maandelijks een foto die recent uit onze nieuwe FEG SEM elektronenmicroscoop (= Field Emission Gun - Scanning Electron Microscope) rolde.

No, this is not the new hairdo of a political leader! This image is taken in the framework of Patecs, a Cornet project, aimed at improving the adhesion between sensor textiles and their protective coating.

In the Free foaming research project we are looking for a competitive and ecologically valid answer to the increasing demand of foam polymer products, by reconsidering the foaming technology and the chemical agents that are being used
After exposing some textile samples to biofouling on the roof of the Centexbel building in Gent-Zwijnaarde, we discovered some beautiful, but unknown organisms. Thanks to the expertise of Lander Blommaert (PhD student) and Prof. Dr. Dominique Adriaens - Ghent University - Evolutionary Morphology of Vertebrates & Zoology, we may now assure you that it is a picture of "Epipyxis condensata".
This test was carried out in the framework of the Affitex project
The word cashmere is an old spelling of the Kashmir region in northern India and Pakistan. Cashmere is fine in texture, strong, light, and soft. Garments made from it provide excellent insulation, approximately three times that of sheep wool. Cashmere is also softer than regular wool.

PES knitwear treated with chitosan, where 1,2,3,4-Butanetetracarboxylic acid (BTCA) is used as crosslinker.
BTCA or 1,2,3,4-Butanetetracarboxylic acid is a carboxylic acid. Carboxylic acids donate hydrogen ions if a base is present to accept them. They react in this way with all bases, both organic and inorganic.
Chitosan is a natural biopolymer showing good biocompatibility, bio-absorbability, wound-healing, haemostatic, anti-infection, anti-bacterial, non-toxic and adsorption properties.

What about probability?
Non-wovens look like an endless three dimensional network of entangled fibres. But is it just an everlasting repetition of disorder ?

Ever wondered what a three dimensional labyrinth looks like? Perhaps this cross section view of a polyurethane foam is very near your imagination.
Click on the picture to see what you encounter while wandering through the labyrinth... Creepy… isn’t it ?

The glossy aspect of the filaments hinders visualisation. The SEM electron image (to be seen after you click on the image) generates a sharp picture but without colour information. EDX (insert) mapping adds information on the composition of the antimicrobial fibres identifying them as silver coated monofilaments.
Composition of the sock: 82% cotton - 6% polyamide - 3% elastane - 9% silver monofilament

In the framework of the research project Fibriltex, blends of non-compatible polymers, such as PP and PET are processed in textile extrusion. The first results are promising as shows the picture above: PP and PET can be extruded together resulting in microsized fibrils within the textile filaments. These innovative yarns can be applied in various technical textiles or further processed into thermoplastic composites in which the fibrils form the reinforcement phase.
