  • Example 7 Using the nonwoven fabric prepared in Example 7 for Combustion Test Combining with urethane foam, a simple mattress was created by the method of creating a simple bed for flame retardancy evaluation, and the flame retardancy was evaluated. The results are shown in Table 3.
  • Examples 7 and 8 had good flame retardancy.
  • Comparative Examples 6 and 7 were not knitted fabrics compared to Examples 7 and 8, and therefore, the shrinkage of the fiber due to heat could not be absorbed, the carbonized film was broken, and the urethane foam was ignited.

Abstract

L’invention concerne un tissu tricoté ininflammable capable de doter d’un haut niveau d’ininflammabilité du mobilier recouvert de tissu, comme des matelas et des fauteuils, ou de la literie, comme des oreillers, des alaises et des futons, tout en préservant la texture et le confort propres aux matériaux (comme le coton et la mousse uréthane) utilisés dans le mobilier et la literie. Selon l’invention, une structure intérieure d’un matelas est recouverte d’un tissu tricoté ininflammable composé d’au moins deux types de fibres sélectionnées dans le groupe comprenant des fibres halogénées (A), des fibres de cellulose (B), des fibres de cellulose ignifuges (C) et des fibres de polyester (D), et est caractérisée en ce qu’elle présente un grammage supérieur ou égal à 140 g/m2, une épaisseur supérieure ou égale à 0,5 mm et une teneur en ignifugeant supérieure ou égale à 2% sur la base du tissu tricoté.
