Abstract
A needle punched carpet for use in a car is disclosed. The needle punched carpet comprises at least a needle punched facing layer defining a top layer and made of staple fibers. The staple fibers comprise hollow fibers having a hollow fiber content that is at least more than 45 weight % of the total staple fibers.
Claims23
A needle punched carpet, comprised of:
- a needle punched facing layer made of a non-woven web having an area weight of between approximately 180-800 g/m2, and which is comprised of polyester hollow staple fibers not of conjugate or bicomponent construction and other staple fibers, processed by a first needle punching process and a second needle punching process;
- and
- a secondary layer associated with the facing layer, wherein the facing layer is the topmost layer of the needle punched carpet that is adapted for direct contact with abrasion-causing compression.
A needle punched carpet, comprising:
- a facing layer produced from a fibrous non-woven web processed by a first needle punching process and a second needle punching process, the facing layer having an area weight of between approximately 180-800 g/m2 and comprised of hollow staple fibers and other staple fibers, wherein the hollow fibers are made of polyester and are not of conjugate or bicomponent construction, and wherein a hollow fiber content of the needle punched carpet is at least more than 45% by weight of the total staple fiber content;
- a secondary layer associated with the facing layer, wherein the secondary layer is a heavy layer comprised of a mass spring system;
- and
- wherein the facing layer is the topmost layer of the needle punched carpet.
