Patent

CA 2362137

A heat-resistant crimped yarn being free from the deterioration of quality due to heating, characterized in that the yarn comprises heat-resistant, highly functional fibers and has a stretch elongation of 6 % or more, a stretch modulus of 40 % or more and a strength of 0.15 to 3.5 N/tex. The heat- resistant crimped yarn is significantly reduced in the quality deterioration of heat-resistant, highly functional fibers due to heat treatment during manufacturing operations, maintains excellent properties such as high heat resistance and flame retardency which are inherent to the heat-resistant, highly functional fibers, and also has good stretch elongation and stretch modulus and excellent appearance, and further is less prone to the production of fluff or dust during the use thereof.

L'invention concerne un fil texturé, thermo-résistant, dont la qualité ne se détériore pas au chauffage, caractérisé en ce qu'il comprend des fibres thermo-résistantes, très fonctionnelles, ainsi qu'un extensibilité de 6 % ou davantage, et en ce qu'il possède un module d'étirement de 40 % ou plus et une résistance comprise entre 0,15 et 3,5 N/tex. Les fibres thermo-résistantes, très fonctionnelles, de ce fil ne se détériorent pratiquement pas lors du traitement à la chaleur pendant les opérations de fabrication, le fil conservant d'excellentes caractéristiques -telles que résistance élevée à la chaleur, anti-feu- inhérentes à ses fibres thermo-résistantes et très fonctionnelles, et il possède également une bonne extensibilité, un bon module d'étirement et un excellent aspect, et il est en outre moins enclin à pelucher lors de son utilisation.
