Organic Fiber Twisted Yarn Cord
Provided is an organic fiber doubled-and-twisted yarn cord the twist structure of which is uniform and with which it is possible to reduce weight. A doubled-and-twisted yarn cord comprising an organic fiber characterized in that a total fineness is 5000-15000 dtex inclusive, a coefficient of twisted yarn length difference between untwisting yarns constituting the doubled-and-twisted yarn cord that is obtained by an expression: coefficient of twisted yarn length difference (%)=(maximum value of yarn length difference between untwisting yarns)/(average value of yarn length of untwisting yarns)×100 is 1.5% or less, and breaking strength is 7.0 cN/dtex or greater.
METHOD FOR PRODUCING A THREADLIKE REINFORCEMENT ELEMENT
A method for manufacturing a bonded reinforcing textile filamentary element (48) comprising a core and a layer of strands is disclosed. The textile filamentary element in the natural state is assembled. A textile filamentary element in the natural state or pre-bonded textile filamentary element is obtained. The filamentary element in the natural state or pre-bonded filamentary element is coated with an external layer of at least one heat-crosslinkable adhesive composition. The filamentary element in the natural state or pre-bonded filamentary element that is coated with the external layer is thermally treated so as to crosslink the adhesive composition in order to obtain the bonded filamentary element (48). The steps of coating with and of thermally treating the external layer of the filamentary element in the natural state or pre-bonded filamentary element are carried out such that, for an elongation equal to 30% of the elongation at break of the filamentary element in the natural state, the tangent modulus of the bonded reinforcing textile filamentary element (48) is increased compared with the tangent modulus of the filamentary element in the natural state.
HYBRID TIRE CORD AND METHOD FOR MANUFACTURING THE SAME
Disclosed are a high-performance hybrid tire cord capable of realizing high performance and lightweight of a tire, and a method for manufacturing same. The hybrid tire cord of the present invention comprises a PET primarily-twisted yarn, an aramid primarily-twisted yarn, and an adhesive coated on the PET primarily-twisted yarn and the aramid primarily-twisted yarn. In the hybrid tire cord having a predetermined length, the length of the aramid primarily-twisted yarn is 1 to 1.1 times the length of the PET primarily-twisted yarn, after the secondary twist is untwisted.
RUBBERIZED STRENGTH MEMBER FOR ELASTOMERIC PRODUCTS, IN PARTICULAR VEHICLE TYRES, WHEREIN THE STRENGTH MEMBER HAS AT LEAST ONE FIRST YARN, METHOD FOR PRODUCING THE RUBBERIZED STRENGTH MEMBER, AND VEHICLE TYRE HAVING AT LEAST ONE RUBBERIZED STRENGTH MEMBER
The invention relates to a rubberized strength member for elastomeric products, especially vehicle tires, wherein the strength member includes at least one first yarn, to a process for producing the rubberized strength member and to a motor vehicle tire including at least one rubberized strength member.
According to the invention, the first yarn is a yarn of HMLS-PET comprising recycled PET.
SPINNING PACK FOR MANUFACTURING HIGH STRENGTH YARN, AND YARN MANUFACTURING APPARATUS AND METHOD
One embodiment of the present disclosure provides a spinning pack, a yarn manufacturing apparatus including the spinning pack, a yarn manufacturing method using the yarn manufacturing apparatus, and yarn manufactured by the manufacturing method. The spinning pack includes a spinneret having a nozzle unit, a heating unit for heating the nozzle unit, a pack body surrounding at least a part of the spinneret, and a spinning block surrounding the pack body, wherein the spinneret includes a first surface which defines a storage space while facing at least one surface of the spinning block, and a second surface facing the first surface, wherein the nozzle unit includes a plurality of discharge holes and protrudes from the second surface; and wherein the heating unit is disposed at the outer side of the nozzle unit.
Reinforcement Layer and Pneumatic Vehicle Tire
The invention relates to a reinforcement layer for elastomeric products, in particular for the belt bandage (8), having cords as reinforcement, where the cords have at least two yarns, where a first yarn of the yarns is made of polyamide and where the ends of all yarns of a cord are twisted together. The problem addressed by the invention is that of providing a reinforcement layer for elastomeric products which exhibits a relatively high tensile force value for an elongation of 4% or more and which exhibits relatively low shrinkage based on linear density of the reinforcement. This is achieved in that the cords are hybrid cords having precisely three yarns, in that the hybrid cord has the first yarn and a second yarn made of HMLS-PET, in that the hybrid cord has a first yarn or a second yarn as third yarn, and in that the linear density of each hybrid cord is at least 5000 dtex.
Methods For Modification Of Aramid Fibers
Methods are described for treatment of aramid fibers to modify the surface of the fibers. The treated fibers have improved adhesion to elastomer materials as compared to untreated fibers. Modification methods include irradiating the fibers, compressing and straining the fibers under a constant pull force and immersing the fibers in a coupling agent fluid. The treated fibers can be used with elastomers and provide reinforcement elements in products such as tires.
