摘要： The present invention relates to a fabric for an airbag, in particular, a fabric for an airbag comprising the polyester fiber, and a method of preparing the same. The fabric for the airbag according to the present invention is prepared by using a polyester fiber having the cross-section thereof in a flat shape, and there are advantages in that the present fabric is thinner than the fabric made of the circular cross-sectional fiber. It is possible to reduce the amount of the coating resin used and to lighten the weight of the product because of the low surface irregularity and the porosity. Also, the present fabric is superior in tensile strength, tearing strength, air permeability, and the folding property in a module system of the airbag apparatus.

摘要： The present invention relates to a high tenacity polyethylene naphthalate fiber containing a silica compound. This fiber is produced by a method comprising the steps of: (A) melt-spinning a solid phase-polymerized polyethylene-2,6-naphthalate chip containing ethylene-2,6-naphthalate units at more than 85 mole % and a silica compound and having an intrinsic viscosity of 0.70-1.20, to produce a melt-spun yarn; (B) passing the melt-spun yarn through a retarded cooling zone and a cooling zone to solidify the yarn; (C) withdrawing the yarn at such a speed that the undrawn yarn has a birefringence of 0.001-0.1; and (D) subjecting the undrawn yarn to multi-stage drawing at a total draw ratio of at least 1.5 and a drawing temperature of 50-250° C. The polyethylene naphthalate fiber has improved physical properties, such as high tenacity, and a dipped cord produced from this fiber has excellent dimensional stability and tenacity such that it can be advantageously employed as a reinforcement material of rubber products.

摘要： A wire cable for window regulators of automobiles is disclosed. In the wire cable, the core strand has a double-layer twisted strand structure with an F+6+12 element wire structure, and consists of a high-strength synthetic resin filament used as a core element wire (F), six internal element wires primarily twisted around the core element wire to form an internal layer around the core element wire, and twelve external element wires secondarily twisted around the internal layer to form an external layer around the internal layer. Eight external strands, having a single-layer twisted strand structure with a 1+6 element wire structure, are twisted around the core strand to form an 8×7+(F+6+12) element wire structure of the wire cable in cooperation with the core strand. The synthetic resin filament used as the core element wire of the core strand has a diameter slightly larger than that of the internal and external element wires of the core strand. The core strand is also compressed at a compression ratio of 2˜10%, thus bringing its element wires into surface contact with each other in place of point contact. In this wire cable, the element wires of the core strand are not likely to be deformed or broken, thus being improved in its fatigue resistance against a repeated bending action, in addition to improving the productivity of the wire cables.
