20100239817 | LEATHER-LIKE SHEET AND PROCESS FOR PRODUCING THE SAME - A leather-like sheet comprising a microfine long-fiber nonwoven fabric comprising an entangled web structure made of bundles of microfine long fibers and an elastic polymer impregnated in the microfine long-fiber nonwoven fabric. The leather-like sheet has the following features: (1) each of the bundles of microfine long fibers comprises 5 to 70 microfine long fibers having an average single fiber fineness of 0.5 dtex or less; (2) the bundles of microfine long fibers have an average fineness of 3 dtex or less; (3) the entangle web structure comprises superposed webs each comprising the bundles of microfine long fibers; (4) a ratio of the microfine long fibers and the elastic polymer is 70/30 to 40/60 by mass; (5) the elastic polymer is substantially continuous; and (6) a machine direction/transverse direction ratio of breaking strength is 1/1 to 1.3/1, an elongation at break in each of the machine direction and the transverse direction is 80% or more, and a machine direction/transverse direction ratio of elongation at break is 1/1 to 1/1.5. With these features, the leather-like sheet has a natural dense feeling resembling natural leathers, a soft hand a small difference of mechanical properties in the machine direction and the transverse direction, a moderate resistance to elongation and a durable recovery. | 09-23-2010 |
20110039055 | BASE MATERIAL FOR ARTIFICIAL LEATHER AND PROCESS FOR PRODUCING THE SAME - A substrate for artificial leather comprising a nonwoven fabric of bundles of microfine filaments. The substrate for artificial leather simultaneously satisfies the following requirements 1 to 4: (1) the bundle of microfine filaments comprises 8 to 70 microfine filaments having a cross-sectional shape of nearly circle; (2) the bundle of microfine filaments has a cross-sectional area of 170 to 700 μm | 02-17-2011 |
