摘要： PROBLEM TO BE SOLVED: To provide an abrasive cloth with excellent fitting property to an abrasive material, capable of grinding a work to be ground without any damages, and with small irregularities of fuzz density of the surface of the abrasive cloth. SOLUTION: This abrasive cloth is formed of nonwoven fabric of polyamide very thin and short fibers of 0.001-0.1 dtex in mean fineness, the number of the very thin and short fibers is >=2×10 pieces/cm . After preparing normalized image from surface image data captured from a stereoscopic microscope at the magnification of 25 by using an image processor, the image is binarized at the threshold 100, and the surface roughness index obtained by measuring the area of white parts by the pixel unit (1 pixel =(square) 5.6 μm) is 1,000-10,000.

摘要： PROBLEM TO BE SOLVED: To provide a polishing cloth having superior retaining performance of polishing grains, uniform and fine dispersiveness, and superior fitting performance to a polishing object and capable of polishing it into super high precision without damaging the polishing object and responding to the large recording capacity of a recording disk. SOLUTION: This polishing cloth is characterized in having an integral structure of polyamide super-thin and -short fiber nonwoven fabric of 0.001-0.03 dtex in the average fineness and a polymer elastic body, composed of an artificial leather formed by applying the polymer elastic body to the super-thin and -short fiber nonwoven fabric not less than 20 wt.% and not more than 80 wt.%, and having the super-thin and -short fiber density in the artificial leather of 0.200 g/cm and the surface roughness of 5.0 μm or less.

摘要： PROBLEM TO BE SOLVED: To provide a method for production by which a raised artificial leather scarcely causing wrinkle defects of a woven fabric or defects in exposure of weaving yarn is stably obtained. SOLUTION: This method for producing the raised artificial leather is characterized by applying a polymer binder to woven fabrics composed of ultrafine fibers having =700 T/m number of twists, binding the woven fabrics, superimposing the bound woven fabrics, carrying out punching treatment, entangling and integrating the punched woven fabrics, then performing treatment for removing the polymer binder, carrying out treatment for applying a polymer elastic body and raising treatment or applying the polymer binder to a fiber web composed of fibers convertible into ultrafine fibers having =700 T/m number of twists, binding the fiber web and woven fabric, superimposing the bound fiber web and woven fabric, performing punching treatment, entangling and integrating the bound fiber web and woven fabric and subsequently conducting ultrafine fiber forming treatment, treatment for removing the polymer binder, treatment for applying the polymer elastic body and raising treatment.
