A flame barrier made of nonwoven fabric for use as a component of a planar multilayer structure, especially a vehicle or aircraft passenger seat. The flame barrier contains staple fibers made of phenolic resin, para-aramid, or melamine resin, alone or mixed with 20 to 60 wt % preoxidized polyacrylonitrile staple fibers. The nonwoven fabric barrier also contains 15 to 30 wt % vermiculite, which is distributed through the entire volume of the nonwoven fabric. The flame barrier possesses a mass per unit area of 100 g/m.sup.2 to 210 g/m.sup.2. The method of manufacturing the nonwoven fabric flame barrier makes use of water jet needling.

An artificial split suede leather, especially for sport or casual style shoes, is a split, needled, nonwoven material of unshrunk fibers containing at least 20% polyamide fibers by weight of the fibers having a trilobate, Y-shaped cross section. In a process of making it, only needling is used for consolidating the fibers. A spherical filler may also be used.

Artificial split suede leather and a process for producing same

The present invention provides a method for manufacturing a fabric-type artificial leather, wherein a nonwoven fabric is formed by using a dry method to join together hydrophobic fibers. The fabric so formed is densified by needling and the activation of shrinking forces. It is then impregnated with a mixture of a heat sensitive elastomeric bonding agent, powdered barium sulfate and a compound that reacts with acid to form a gas. The impregnated fabric is then exposed to a heated, acidified liquid which triggers coagulation of the bonding agent and liberates a gas formed by reaction of the acid and acid-reactive compound. The resulting solidified fabric is then washed, dried and ground-over on at least one side to produce a nap. Finally, the fabric is intensively fulled.
