Abstract: PROBLEM TO BE SOLVED: To provide a magnetic recording medium processing tape which is capable of applying highly accurate texturing on the surface of a substrate with good yield. SOLUTION: The magnetic medium processing tape is a sheet in which a high polymer elastic body is imparted to an entangled body consisting of extremely thin fibers of =0.3 g/cm3 and the R value, which is obtained with a formula, R value (%)=(R1-R3)/(R1-R2)×100 (where, R1: the quantity of reflected light at 0 deg., R2: the minimum quantity of reflected light within the rotation range of 0 to 180 deg., R3: the quantity of reflected light at 180 deg.) from an angle changing reflection curve measured with an automatic angle changing photometer by rotating a fluffing surface 0 to 180 deg., is controlled to be

Abstract: PROBLEM TO BE SOLVED: To improve the microscopic polishing accuracy by providing a surface of a non-woven fabric base material with an embossed pattern, and specifying a width of projected parts of the embossed pattern. SOLUTION: A non-woven fabric base material composed of extra fine fiber to be used in an abrasive cloth, is manufactured by entangling the extra fine fiber of 0.3 dtex or less. It is an important point to improve the surface accuracy of the non-woven fabric base material prepared like this. The surface accuracy of the non-woven fabric base material is achieved by embossing the extra fine fiber non-woven fabric base material. The arbitrary shape and irregularity can be applied in an embossed pattern in an embossing work, but it is important that an average width of projected parts is 60 μm or less, preferably 40 μm or less. By this embossing work, the microscopic uniform irregularity is formed on the surface of the non-woven fabric base material by applying the embossing pattern of a mold for embossing.

Abstract: PURPOSE:To obtain the title molded item having excellent high temp. alkali resistance, high strength and elastic modulus, high heat resistance and being usable for reinforcing high-temp. curing cement, by binding sulfur in a small amt. below a specified value therewith. CONSTITUTION:The title molded item whose content of bound sulfur is 5wt.% or lower is obtd. by treating an arom. polyamide molded item in the vapor of a sulfur compd. such as SO2 gas at 250 deg.C or higher and thereby introducing sulfur into the arom. polyamide molded item. As the above-described molded items, not only simple fibers, but cut fibers, pulps, woven fabrics, felts, papers, films, boards, resinous materials, etc., are included without any limitation in their shapes and molded items thereof and composites wherein these serve as base materials are also included. These molded items have remarkably excellent high temp. alkali resistance as well as high strength, elastic modulus, and heat resistance. They can be used in the field for reinforcing high-temp. (180 deg.C) (autoclave) curing type of cement which has not been usable heretofore. Furthermore, these molded items can be used not only for reinforcing cement, but also in such industrial applications as asbestos substituting fibers based on their heat resistance and high strength.
