PLASMA TREATMENTS FOR TEXTILES : NEW PRODUCTS AND ENVIRONMENT PROTECTION

Ziel


Different fibres were treated by plasma:
wool (shrink-proofing),
polyamide (dyeability, flame retardancy),
cotton and cotton/polyester (antibacterial),
aramide and polyester (adhesion promotion).

Laboratory scale experiments gave very promising results on all materials and demonstrate the technical interest of plasma treatments applied to textiles. Optimal treatment conditions for each application have been determined.

For treating tops and fabrics at industrial scale, a state of the art on existing plasma machines has shown that the best available equipments are:
- wool tops treatment: LTP5 from the Shanghai Textile Research Institute (China) and the pilot of the Polish Textile Institute of Lodz (Poland),
- fabrics treatment: KPR 180 from NIEKMI (Russia)/TECNOPLASMA (Switzerland).

Industrial scale trials demonstrate the economic interests of such technology for the European textile industry. But, the existing equipments need to be improved and/or rethink for a full integration in the productive line.
The above project will be carried out prospecting 3 ways of treatment using plasma or chemically-assisted plasma urface modifications of natural and synthetic textile materials to obtain high-quality products with permanent new properties, especially non-shrinkabitily, non-feltability and non-flammability. The most important advantage of such new ways of treatment is the very low amount of material desposited, involving nearly no effluents (environment protection) and no touch properties modification of the web.

The chemicals used in conventional processes for dimentional stability or ignifugation are generally toxic and difficult to use. The amount of polluting effluents is important regarding to the yearly production of textile industry and strong inconvenients for environment are generated. The original plasma process proposed in this project is able to modify this situation, regarding to the very low amount of materials involved, and the process yield by comparison with the conventonal. The industrialisation of such process becomes possibvle in textile industry because of the recent apparition on the market of continuous plasma devices both in Europe and Japan.

Pre-production trials and economical study will permit to show the benefits of uch treatments by comparison with conventional ones.
