Abstract:
Fire resistant garments are disclosed made from a fabric containing a fiber blend. The fiber blend contains meta-aramid fibers, fire resistant cellulose fibers, non-aromatic polyamide fibers, and optionally para-aramid fibers. The non-aromatic polyamide fibers are present in an amount sufficient to dramatically improve the abrasion resistance of the fabric without adversely interfering with the flame resistant properties. In addition to abrasion resistance, the particular blend of fibers has also been found to dramatically improve or increase various other properties. In one embodiment, the fabric is made with a herringbone weave which has been found to unexpectedly improve tear properties and porosity.
Abstract:
L'invention concerne deux matériaux géotextiles biodégradables réalisés à partir des fibres extraites de la plante de l'Alfa {de l'arabe halfa) «Stipa tenacissima L.» et du palmier nain (doum) «Chamaerops humilis L». Selon l'invention, les fibres textiles sont extraites de l'alfa par un procédé chimique, le démontage de la lignine est effectué en milieu basique à température et pression bien précises, tandis que les feuilles du doum sont défibrées mécaniquement. Les fibres ainsi extraites de l'alfa et du doum sont respectivement filées et tressées pour produire des filets de géotextiles biodégradables susceptibles d'être accrochés au sol. Ces nouveaux géotextiles constituent une véritable voie de valorisation de ces deux ressources végétales très abondantes dans le bassin méditerranéen et plus particulièrement dans le territoire Marocain.

Abstract:
The present invention relates to lyocell filament fibers and a cellulose-based tire cord, and particularly to lyocell filament fibers of which the swelling anisotropy defined in the specification is 1.1 to 1.4. Furthermore, the present invention provides a cellulose based tire cord of which the swelling anisotropy is 1.1 to 1.4. According to the present invention, there is an effect of providing the lyocell filament fibers and the cellulose based tire cord of which the dimensional stability in a highly humid state is particularly good and thus the tenacity, the elongation, and the modulus are superior to common cellulose based fibers, such as rayon and so on, the property maintaining rate at the post manufacturing process is high, and the processibility is good.
Abstract:
La invención se refiere a un tejido flexible biodegradable que comprende elementos alargados, tales como hilos, mechas o cintas, entrelazados o entrecruzados entre ellos, obtenidos a partir de fibras de papel o de una tela no tejida de celulosa, preferiblemente procedente de coniferas. El tejido puede comprender tratamientos para incrementar las propiedades de filtrado de la radiación cósmica y tratamientos con sustancias ignífugas, hidrófugas, fungicidas, bactericidas o colorantes. La invención también se refiere al uso del tejido como recubrimiento para superficies interiores de vehículos o aeronaves, o como cubrimiento para invernaderos, carpas y similares.
