    Abstract: The present invention provides a sliding member which is superior to a conventional polyamide sliding member not only in mechanical properties (especially, flexural property) but also in sliding property. The present invention relates to a sliding member comprising unmodified cellulose fibers or cellulose fibers in which a part of hydroxyl groups from cellulose has been modified with a hydrophilic substituent, which have an average fiber diameter of 10 μm or less, in an amount of 0.1 to 50 parts by mass with respect to 100 parts by mass of a polyamide resin.

    Abstract: Provided is a method for producing a semi-product for automobile equipment, the semi-processed product being moldable in a relatively broad range of heating temperatures and being capable of obtaining a final product with high stiffness. In the method for producing a semi-processed product for automobile equipment, needle punching is performed on a fiber web in which core-sheath composite fibers are accumulated, and the core-sheath composite fibers are three-dimensionally interlaced together. The core portion of the core-sheath composite fibers comprises a copolymer of ethylene glycol and terephthalic acid. The sheath portion of the core-sheath composition fibers comprises a copolymer including ethylene glycol, adipic acid and terephthalic acid. The weight ratio of core portion to sheath portion in the core-sheath composite fibers is 1 to 3:1. The core portion and the sheath portion are disposed concentrically. In the fiber web, the core-sheath composite fibers are bonded together by softening or melting the sheath portion.

    Abstract: A primary base fabric for a tufted carpet includes a first non-woven web and a second non-woven web laminated on each other. The first non-woven web is constituted with a first constituent fiber formed with a first thermoplastic resin and containing carbon. The second non-woven web is constituted with a second constituent fiber formed with a second thermoplastic resin and having a carbon content lower than the carbon content of the first constituent fiber or containing no carbon. The primary base fabric is a product prepared by combining the first non-woven web and the second non-woven web through an emboss processing.

    Abstract: An object of the present invention is to provide a bismaleimide using an aliphatic diamine, in which acid components remaining as an impurity at a very small amount in the bismaleimide have been effectively removed, that is, a bismaleimide using an aliphatic diamine, an acid value of which has sufficiently been reduced, and a method for producing it. There are provided a bismaleimide using an aliphatic diamine as a diamine component, characterized in that an acid value thereof is 2 mg-KOH/g or less, and a method for producing the bismaleimide, comprising adding carbodiimide to a solution comprising a crude bismaleimide having an acid value of more than 2 mg-KOH/g, and reacting acid components in the crude bismaleimide with carbodiimide.
