    Abstract: PURPOSE:A sheet like leather having natural appearance and deep luster, having a silver face layer consisting of ultrafine fibers having distance between entanglements in a specific range, being densely entangled, and/or their bundles and a urethane polymer containing a specific segment. CONSTITUTION:Fibers of ultrafine fiber-forming type (e.g., sea island type fiber) producing ultrafine fibers having =5wt% polyether having 500-5,000 polyether (e.g., polyethylene glycol) as the whole segment of the urethane polymer to form easily hydrogen bond in an aqueous solution, and grain pattern is formed on the coated surface by embossing rollers, and the sheet is dyed by a conventional procedure.

    Abstract: PURPOSE:To provide the titled sheet having excellent durability and deep luster colored in high fastness, by three-dimensionally entangling composite fibers capable of forming ultrafine fibers, and blasting a high-speed fluid jet toward the entangled fibers, thereby carrying out the application of the resin containing colorant, the ultrafibrillation of the fiber, and the dyeing with a reactive dye at the same time. CONSTITUTION:(A) Multi-component fibers capable of forming ultrafine fibers finer than 0.05 denier are subjected to the three-dimensional entanglement to obtain a fiber sheet. (B) A high-speed fluid jet is blasted toward at least one surface of the sheet to effect the splitting of the multi-component fibers and the mutual entanglement of the fibers. (C) The surface blasted with the high-speed fluid jet is coated with a resin containing 3-300%, preferably 10-100% colorant (based on the solid content of the resin) (the amount of the resin is when flexibility is required, and 5-50g/m when abrasion resistance is required.). (D) The fibers are fibrillated to form ultrafine fibers. (E) The product is dyed with a reactive dye. The above process may be carried out in the order A B D C or A D B C interposing the step E at an arbitrary position.

    Abstract: PURPOSE:To obtain a composite nonwoven fabric having different color patterns and high discoloration and fading fastness, excellent in tensile strength, moisture permeability, water proofness or wind protecting properties and having filterability, blood barrier properties, oil adsorbability or chemical resistance. CONSTITUTION:A colored spun bond nonwoven fabric (B) with an average fiber diameter of 10mum or more and a wt. basis of 10-80g/m is laminated to at least the single surface of a melt blow nonwoven fabric (A) with an average fiber diameter of 5mum or less and a wt. basis of 10-200g/m and both of them are integrated by partial thermal bonding to obtain a composite nonwoven fabric.
