Abstract

Selon l'invention, on prépare des fibres composites creuses constituées de 16 à 96 segments disposés alternativement de polyester ou de polyamide et de polystyrène adhérant mutuellement côte à côte et formant un espace creux tout le long de l'axe longitudinal de la fibre, ladite fibre composite creuse ayant un denier de 1 à 20 et chacun des segments un denier de 0,01 à 0,5, on confectionne une étoffe à l'aide de ces fibres, on élimine des fibres les segments de polystyrène à l'aide d'un solvant approprié et on applique un polymère élastique sur l'étoffe. Les matières en feuilles préparées conformément à l'invention ont l'aspect du cuir de Suède.According to the invention, hollow composite fibers are prepared consisting of 16 to 96 segments arranged alternately of polyester or polyamide and polystyrene adhering to each other side by side and forming a hollow space all along the longitudinal axis of the fiber, said hollow composite fiber having a denier of 1 to 20 and each of the segments a denier of 0.01 to 0.5, a fabric is made using these fibers, the polystyrene segments are removed from the fibers using a suitable solvent and an elastic polymer is applied to the fabric. The sheet materials prepared in accordance with the invention have the appearance of suede leather.
