    Abstract: PURPOSE:To obtain the subject yarn not changing a color, having excellent durability, flame-proofness and productivity by adding a specific amount of a bifunctional phosphorus compound to polyester yarn. CONSTITUTION:The objective yarn comprising polyester yarn composed of >=85% repeating unit polyethylene terephthalate mixed with 0.3-1.5wt.%, preferably 0.4-1.0 bifunctional phosphorus compound such as dimethyl phenylphosphonate.

    Abstract: PURPOSE:To obtain a piece of waterproof canvas which has bulky feeling and is superior in durability, by a method wherein polyester filament is an aggregate where a number of pieces of single yarn are specific, the pieces of single yarn each possess a noncircular sectional form, confounded by forming a loop, base cloth is formed by weaving a polyester filament, the surface is coated with vinyle chloride resin and processed. CONSTITUTION:At least 85% of the whole repeating unit of a molecular chain is a polyester filament comprised of a polyethylene terephthalate and the polyester filament is an aggregate comprised of a number of pieces of single yarn of 90-300 pieces. The pieces of single yarn each possess a noncircular sectional form which is confounded by forming a loop, base cloth is formed by weaving the polyester filament and the title canvas is constituted by coating the surface of base cloth with vinyl chloride resin at 200-350g/m . When the pieces of the single yarn are fewer than 90 pieces, binding force among the pieces of the single yarn is lowered. When they are more than 300 pieces, since opportunities where a movement of the pieces of the single yarn is restricted become many, confounding or a loop by a fluid nozzle is reduced extremely.

    Abstract: PURPOSE:To obtain a safety net having knitting strength, impact absorption resistance, flame retardance, light resistance, etc., by knitting a specific spun- dyed polyester yarn consisting essentially of polyethylene terephthalate, CONSTITUTION:Synthetic yarn of spun-dyed polyester having >=90mol% whole repeating unit of molecular chain comprising polyethylene terephthalate is knitted by raschel knitting machine into mesh woven fabric, which is heat-treated. The spun-dyed polyester yarn has >=0.7 intrinsic viscosity, >=7.0g/d strength at break, >=15% elongation at break, >=110 toughness, >=4.5g/d loop strength, >=45% light resistance and contains 0.3-1.0wt.% calculated as phosphorus element amount of bifunctional phosphorus compound.

    Abstract: PURPOSE:To reduce stain on drawing roller and end breakage and to obtain polyester yarn for reinforcing rubber free from change with time by supplying a treating agent containing an epoxy compound to polyester yarn immediately after separation from a relaxing heat treatment roller after roller drawing. CONSTITUTION:In drawing polyester yarn prepared by melt spinning by using a drawing roller group and subjected the yarn to relaxing heat treatment using a relaxing roller, temperature of the final roller among in the drawing roller group and temperature of relaxing heat treatment roller are controlled in a range of 150-235 deg.C and the yarn is provided with a treating agent containing an epoxy compound immediately after the separation from the relaxing roller and is wound.

    Abstract: PROBLEM TO BE SOLVED: To obtain a cement reinforcing fiber having excellent affinity and dispersibility as a reinforcing fiber to be dispersed into cement in order to obtain a cement molding having improved flexural strength, improved control of propagation of crack, etc. SOLUTION: In this method for producing the cement-reinforcing fiber a synthetic fiber multifilament having 1,000-10,000 dtex total fineness is twisted at 400-2,700 twist coefficient K, provided with a surface treating agent to give a dip cord having >=5% elongation at 2 cN/dtex and >=5.5 cN/dtex strength at break, which is cut into 10-60 mm fiber length. The twist coefficient K is T×D (T: number of twists (t/10 cm) and D: total fineness (dtex).

    Abstract: PURPOSE:To reliably protect an occupant even if the occupant encounters with an accident by improving lateral directional rigidity, providing a stable housing characteristics, and making a seat belt hard to be reversed. CONSTITUTION:Webbing for a seat belt is characterized in that synthetic fiber having a cross-sectional shape of a noncircular or hollow shape is used as the weft constituting the webbing. The synthetic fiber constituting the weft is composed of polyester mainly composed of polyethylene terephthalate, and is preferable to be fiber whose cross-sectional shape is selected from a Y shape, a C shape, a triangle shape and a noncircular shape and also a hollow shape.
