摘要： The present invention relates to soft touch fibers and nonwoven fabrics made from such fibers. The fibers comprise an incompatible polymer system which leads to the soft touch quality. The fibers comprise a mixture of at least two thermoplastic polymers each having different viscosities and wherein the mixture has an interfacial tension from about 0.5 to about 20 mN/m, and wherein the mixture comprises a portion of the fiber surface. The fibers may include from 40-98 percent of a polyolefin continuous phase and from 2 to 60 weight percent of an amorphous thermoplast dispersed phase, such as polystyrene or polyamide.

摘要： A multilayer structure comprising (A) a fabric and (B) a polymeric layer comprising a substantially random interpolymer comprising in polymerized form i) one or more alpha -olefin monomers and ii) one or more vinyl or vinylidene aromatic monomers and/or one or more sterically hindered aliphatic or cycloaliphatic vinyl or vinylidene monomers, and optionally iii) other polymerizable ethylenically unsaturated monomer(s); layer (B) being free from a substantial amount of tackifier. The multilayer structure has desirable haptics and surprisingly good drape properties. It is useful in many applications, for example as water-impermeable clothes, tablecloths, tents, water-impermeable covers, curtains, artificial leather or upholstery.
