摘要:
Layered nonwoven textile containing
a first layer (T) of filaments, which contains endless filaments containing a first carrier polymer (A1) and a first binding polymer (B1), which forms at least a part of surface of said endless filaments and which has a melting temperature at least 5° C. lower than the first carrier polymer (A1), wherein the first layer (T) of filaments contains bonding points in a spaced arrangement, wherein the bonding points interconnect the filaments and are formed by the first binding polymer (B1),
a second layer (M) of filaments, which contains filaments containing a carrier material, the stiffness of which is lower than the stiffness of the first carrier polymer (A1), and a second binding polymer (B2), which has a melting temperature at least 5° C., preferably at least 10° C., lower than the carrier material and the first carrier polymer (A1), wherein the second layer (M) of filaments contains bonding points in a spaced arrangement, wherein the bonding points interconnect the filaments of the second layer (M) and are formed by the second binding polymer (B1).
