Resource-efficient coating technologies for improved durability of high strength textiles

In the CORNET project ResCoTex (IGF-No. 109 EBR/1), led by the Forschungskuratorium Textil e.V., the Sächsisches Textilforschungsinstitut e.V. (STFI) cooperated with the Belgian research partner Centexbel, high strength textiles in form of ropes, belts, nets and fabrics are used in specific applications for protecting/securing objects or people. Examples are securing of cargo, ladders, people on construction sites, heavy weight lifting belts & nets, etc.

During their application these textile materials are exposed to manifold environmental influences (sunlight/UV, heat, humidity, abrasion,…) and high loads, which can vary strongly and abruptly. There were no systematic methods existing to assess the degree of ageing by simulating real use (i.e. under heavy load) and to predict when to replace the textile components.

Therefore, the project ResCoTex aimed to improve the performance of these materials and to develop new testing and detection systems especially for lashing belts used in load securing systems. To improve the resistance of the textile structures towards influences like UV/sunlight, heat, humidity or abrasion, functionalised textile coatings and finishes were applied using resource efficient techniques. Formulations were tested which are industrially feasible and achieve equal and even better protection for webbing band materials.

Improved test methods were developed to assess the degree of ageing simulating real use (i.e. under heavy load or UV-influence) and to predict the point of replacement for the textile components. For the investigation of complete lashing systems a new test rig was developed where such systems can be tested and evaluated under real life conditions in the form of a full scale test. Furthermore, visual detection systems (UV-indicator, abrasion indicator and heavy load indicator) were developed to assess the degree of ageing and thus, a new and assuring way to deal with these materials by predicting the end of life was investigated.
