Abstract: PURPOSE: To provide interlining with proper rigidity as well as soft wearing feeling and obtain resistances to washing, which comprises a resin base having a specified bending modulus of elasticity, and a resin sheath having a specified bending modulus of elasticity and hardness. CONSTITUTION: Interlining for clothing is constituted of a resin base A, having bending elastic modulus of 9000kg/cm , and a resin sheath B, having a bending modulus of elasticity of 5000kg/cm or less and a hardness of 25-65 in shore D-hardness. The base A is constituted preferably of a thermosetting resin such as polyamide, polybutylene terephthalate, polyethylene terephthalate, polyacetal and the like. Polyamide elastomer, polyester elastomer, polyorefin elastomer and the like are used for the sheath B. In order to obtain the sufficient bonding property of an interface between both units, the combination of resins having amide structure and ester structure respectively is preferable. On the other hand, it is effective to provide with the bonding layer of modified polyolefin or the like between the core unit and the sheath unit.

Abstract: PROBLEM TO BE SOLVED: To provide a floor support made of a synthetic resin, having excellent mechanical strength and chemical resistance and capable of guaranteeing a smooth floor lifting operability by molding at least one of multiple tubular members which are relatively moved and expanded or shrunk in the axial direction with a polyamide resin composition containing a reinforcing material of a specific wt.%. SOLUTION: Press nuts 2, 2 are screwed to both end sections of a bolt 1, and stopper nuts 3 for stopping the loosening of the press nuts 2 are screwed inside to form this floor support. A polyamide resin composition mixed with a reinforcing material of 1-60 wt.% unto a polyamide resin is injection-molded into a completely round cylindrical shape to form the bolt 1, thus compressive strength is improved and can be kept at a high level under the high-humidity condition. Male screws 4a, 4b having opposite screw directions are provided at both end sections across the center section in the axial direction of the bolt 1. The polyamide resin composition mixed with the reinforcing material into the polyamide resin is likewise injection-molded into the completely round cylindrical shape to form the press nuts 2 and the stopper nuts 3.

Abstract: PROBLEM TO BE SOLVED: To provide a high bending characteristic, color tone and lightweight quality by containing a polyester resin having a specific range of weight parts composed of cyclohexane dimethanol and an aromatic dicarboxylic acid, and one or more types of rod type inorganic substances within the specific range of weight parts. SOLUTION: A polyester resin composition is prepared through the process where 60 to 10 pts.wt. of glass fiber as one or more of rod type or acicular inorganic substances are blended, melted and kneaded with 40 to 90 pts.wt. of resin as a copolymer made of cyclohexane dimethanol and aromatic dicarboxylic acid consisting of 95mol% of telephthalic acid and 5mol% of isophthalic acid. This polyester resin composition is used and extrusion molded at the resin temperature of 300 deg.C and the die temperature of 150 deg.C, thereby preparing resin chopsticks. As a result, the chopsticks have a high bending characteristic, color tone and lightweight quality.
