Abstract:
Method of treatment of textile reinforcing materials with the aim to increase their adhesion to rubber compound for application in tires, conveyor belts, as well as for products of technical rubber and V-belts, by low temperature plasma at atmospheric pressure, in which method the textile material is treated, without any preliminary preadhesive treatment, by low temperature plasma generated at atmospheric pressure in a plasma chamber, into which a gas mixture of propane-butane with nitrogen is fed, while plasma polymerization of propane-butane and deposition of a polymer layer at the surface of the treated textile material take place.
Abstract:
Sheet material for absorbing liquid has a first fibre layer with a pattern of a modifying agent applied thereto, the modifying agent being substantially more hydrophobic or hydrophilic than the fibres, thus modifying the performance of the fibre layer. A method of modifying the absorbency and liquid flow characteristics of a non-woven fabric comprising: (i) procuring a non-woven textile fibre first sheet material; (ii) selecting a modifying agent which is substantially more hydrophobic or hydrophilic than the fibres of the non-woven sheet material; and (iii) applying the modifying agent to the non-woven sheet material in a pre-selected pattern. The material made is of particular use as an absorbent layer in an incontinence product or wound dressing, facilitating the spread of liquid throughout the layer.
Abstract:
A porous substrate (12) is pretreated in a plasma field (20) and a functionalizing monomer is immediately flash-evaporated (22), deposited and cured (24) over the porous substrate in a vacuum-deposition chamber (10). By judiciously controlling the process so that the resulting polymer coating adheres to the surface of individual fibers in ultra-thin layers (approximately 0.02-3.O micrometers) that do not extend across the pores in the material, the porosity of the porous substrate (12) is essentially unaffected while the fibers and the final product acquire the desired functionality. The resulting polymer layer is also used to improve the adherence and durability of metallic and ceramic coatings.
Abstract:
Die vorliegende Erfindung betrifft einen Gassack (10) für ein Rückhaltesystem in Fahrzeugen, eine Vorrichtung zum Schutz von Fahrzeuginsassen mit einem derartigen Gassack, ein Verfahren zur Herstellung des Gassacks sowie die Verwendung eines Gewebes für den Gassack. Der erfindungsgemäße Gassack hat eine Wandung (24) aus Gewebe (18, 20, 22), wobei eine Oberfläche (26) des Gewebes zur Steigerung der Hitzebeständigkeit plasmabehandelt ist.
Abstract:
The present invention relates to methods for the preparation of solid-supported heterogeneous organic catalyst covalently bound to textile materials, preferably via photochemical immobilization. More specifically, the present invention relates to the organocatalysis and recognition process by using the textile-supported chiral molecules.
Abstract:
A method for treating an item which, in use, is subjected to flexing, to reduce its susceptibility to water penetration over time during use, said method comprising forming a water repellent coating or surface modification on the surface of the item by ionisation or activation technology.
Abstract:
A method for protecting an item from weight gain due to uptake of liquid comprising exposing said item to plasma in a gaseous state for a sufficient period of time to allow a protective layer, particularly a polymeric layer, to be created on the surface of the item.
