Method for the treatment of single-filament polyethylene terephthalate cords for the reinforcing layers of a pneumatic tyre comprising (a) an adhesive solution coating step, wherein the single filament cord is immersed in an adhesive solution; (b) a drying step, wherein the cord covered in adhesive resin is held within a drying oven at a temperature of between 120 and 180° C.; and (c) a thermobonding step wherein the cord, proceeding from the drying step, is arranged within an oven at a temperature of between 230 and 260° C. for a period of between 30 and 90 seconds. During the thermobonding step, the single filament cord is subjected to a tension of between 8 and 12 mN/dtex.

The invention relates to a metallic reinforcing cord (10) for tyres for vehicle wheels, comprising at least two metallic wires (11) twisted together with a predetermined twisting pitch (P). The metallic reinforcing cord (10) has a part load elongation greater than 3%, preferably greater than 3.5%.

A nylon 6.6 yarn suitable for a tire cord reinforcement for pneumatic tires includes higher than 12,0 g/dtex Tensile Reinforcement Index (TRI) and tenacity between 9,3 g/dtex-10,5 g/dtex, where the TRI is defined as: TRI (g/dtex)=Tenacity (g/dtex) +Stress at 7% Elongation. The nylon 6.6 yarn is suitable for using as tire cord reinforcement in pneumatic tires.

A monofilament made of glass-resin composite has improved properties in compression, in particular at high temperature, and comprises glass filaments embedded in a crosslinked resin. The glass transition temperature of the resin is equal to or greater than 190° C. The elongation at break of the monofilament, measured at 23° C., is equal to or greater than 4.0%. The initial tensile modulus of the monofilament, measured at 23° C., is greater than 35 GPa. The real part of the complex modulus of the monofilament, measured at 190° C. by the DMTA method, is greater than 30 GPa. Pneumatic or non-pneumatic tires are reinforced with such a composite monofilament.

Tyre comprising a carcass, a belt package and a tread; said tyre comprising at least a reinforcement net made of a weaved textile material having a number of meshes ranging from 3 to 20, and wherein the threads are oriented between 25° and 65° relative to a longitudinal axis (X) of the tyre; said reinforcement net being arranged at least in the area of a centre of the tread and positioned inside the belt package or between the belt package and the tread; said weaved textile material having an elongation at break equal to or greater than 10%; said reinforcement net having a shorter transverse extension than the one of the belt package.

Shape memory alloy elements (“SMAs”) are bonded, encased, or encapsulated with one or more polymers to form an integrated component with unique elastic, pseudoelastic, and load-bearing properties.

Provided is a steel cord for rubber article reinforcement which has excellent corrosion resistance and productivity without deterioration of adhesion with rubber. A steel cord (1) for rubber article reinforcement, in which plural steel filaments (2) are twisted together, includes: a core having at least one core filament (2c); and a sheath having at least one sheath layer formed by twisting at least one sheath filament (2s) around the core. In this steel cord (1), brass plating is performed on the steel filaments (2) and zinc plating is further performed on the outer circumference of the brass plating of the core filament (2c), and the steel filaments (2) have a diameter d of 0.1 mm to 0.6 mm.

Disclosed is a pneumatic radial tire for a passenger car having ultra fine steel cords for a carcass ply in which adhesive force between a carcass ply layer and a side wall or a rim flange rubber adjacent to a turn up portion on an outside and a stiffness of the rim flange rubber are larger than a bending stiffness of the carcass ply layer so as to improve durability of a bead part while reducing poor air inletting generated at a carcass turn up portion.

A bicycle-tire reinforcing ply comprising a woven fabric that comprises liquid crystalline polyester fiber yarns, wherein each of the fiber yarns comprises three or more single fibers having an average fiber diameter of 25 μm or larger, and the fiber yarns satisfies the following formula:

[No. of single fibers per fiber yarn]×[average fiber diameter (μm)]≤1700.

The present invention discloses a preparation method of polyester cord fabric with low denier and high modulus, including steps of: spinning, reducing melt discharge volume for extruding yarn with denier of 500-1000 D; using high-speed motor and heat roller, spinning speed of 6000-6500 m/min to produce raw yarn; performing initial and repeat twisting of raw yarn by straight twisting machine; performing weaving of twisted yarn using Dornier air-jet loom to produce cord fabric, when weaving and reeding-in, using two into a reed way, adding creel roller bearing and creel single spindle tension control belt to improve uniformity; performing dipping of cord fabric using two-bath dipping, adjusting temperature to 250-260 degrees Celsius, tension to 0.3-2.9 daN/each yarn of key area, running speed of yarn to 55-70 m/min. The polyester cord fabric with low denier and high modulus can reduce rolling resistance and fuel consumption, and improve performance.
