摘要: 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.

摘要: 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.

摘要: An air filter material for intercepting dust is disclosed. The material is free of lubricants and antistatic agents, and consists of a blend of (I) polyolefin fibers and (II) polyacrylonitrile fibers that are geometrically stable. The fibers (I) are two-component polypropylene/polyethylene fibers of the core/jacket or side-by-side type, and fibers (II) are halogen-free. The fiber blend is washed during the manufacturing process after they are first combined.
