| 20080200630 | Medical Resin Composition, Process For Producing Resin Composition and Process For Producing Molded Article - A medical resin composition is produced by mixing a powder of a polymer (A) comprising repeating units having an ester group and a liquid of a vinyl ester monomer (B) having 6 or more carbon atoms to increase a viscosity and, according to demand, further performing a polymerization reaction. The thus produced resin composition inhibits leaching of irritative substances, reduces any adverse effects on the human body by endocrine disruptors, etc. and can be prepared with high operational efficiency. The resin composition is suitably used as a dental resin composition such as a tissue conditioner, a functional impression material, a lining material, a denture base material or a mouth piece material. | 08-21-2008 |
| 20090053948 | BASE FOR SYNTHETIC LEATHER AND SYNTHETIC LEATHERS MADE BY USING THE SAME - A substrate for artificial leathers, comprising a nonwoven fabric body made of microfine fiber bundles and an elastic polymer impregnated therein. The substrate for artificial leathers simultaneously satisfies the following requirements 1 to 4: (1) each of the microfine fiber bundles contains 6 to 150 bundled microfine long fibers in average; (2) a cross-sectional area of the microfine long fibers constituting the microfine fiber bundles is 27 μm | 02-26-2009 |
| 20090087618 | BASE MATERIAL FOR ARTIFICIAL LEATHERS AND METHOD OF PRODUCING THE SAME - A substrate for artificial leathers which is composed of a nonwoven fabric made of fiber bundles of microfine fibers having an average single fiber fineness of 0.5 dtex or less and an elastic polymer impregnated into the nonwoven fabric. The substrate for artificial leathers satisfies the following requirements 1 and 2: (1) the number of fiber bundles which are oriented to a thickness direction of the nonwoven fabric is 75 to 300 per 1 cm of width which is perpendicular to the thickness direction, when measured on a cross section parallel to the thickness direction; and (2) the number of cross sections of the fiber bundles which are oriented to the thickness direction is 30 to 800 per 1 mm | 04-02-2009 |
| 20090124156 | BASE MATERIAL FOR ARTIFICIAL LEATHER AND GRAINED ARTIFICIAL LEATHER - A substrate for artificial leathers composed of an entangled nonwoven fabric made of microfine fibers and a binder resin. At least one surface of the substrate for artificial leathers is a densified layer which is made of the microfine fibers and which is substantially free from the binder resin. The binder resin is impregnated into a portion of the substrate for artificial leathers other than the densified layer. The densified layer prevents the binder resin impregnated into the entangled nonwoven fabric from migrating into the surface of the entangled nonwoven fabric, thereby providing the substrate for artificial leathers having the surface substantially free from the binder resin. The peeling strength between the substrate for artificial leathers and a grain layer formed on the surface thereof is drastically improved because the surface of the substrate for artificial leathers is substantially free from the binder resin. | 05-14-2009 |
| 20090274862 | Leather-Like Sheet And Method Of Manufacturing The Same - A leather-like sheet composed of a microfine-fiber entangled body made of bundles of microfine fibers and an elastic polymer impregnated therein. The bundles of microfine fibers are composed of microfine monofibers having an average cross-sectional area of 0.1 to 30 μm | 11-05-2009 |
| 20100086738 | LEATHER-LIKE SHEET BEARING GRAIN FINISH AND PROCESS FOR PRODUCING THE SAME - A (semi)grain-finished leather-like sheet composed of an entangled nonwoven fabric of three-dimensionally entangled fiber bundles containing microfine long fibers and an elastic polymer contained in the entangled nonwoven fabric. When dividing the (semi)grain-finished leather-like sheet to five layers with equal thickness, i.e., surface layer, substrate layer | 04-08-2010 |
| 20100159771 | BASE MATERIAL FOR ARTIFICIAL LEATHER AND METHOD OF PRODUCING THE SAME - A substrate for artificial leathers which is composed of a united laminate of a nonwoven fabric layer A made of bundles of microfine fibers having an average single fiber fineness of 0.5 dtex or less and a cushion layer B made of an elastic polymer sheet. A part of the microfine fibers constituting the nonwoven fabric layer A is allowed to penetrate through the cushion layer B to form a microfine fiber layer C on the outer surface of the cushion layer B. The inner surface of the elastic polymer sheet is undulated with a height difference of 100 μm or more in a thickness direction. Between the undulated surface of the elastic polymer sheet and the nonwoven fabric layer A, voids having a height of 100 μm or more in a thickness direction are formed. Using the substrate for artificial leathers, grain-finished artificial leathers which combine a softness without resistance and a stiff hand resembling natural sheep leathers and have bent wrinkles with fullness are produced. | 06-24-2010 |
| 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 |
