摘要:
A pneumatic tire has a tire skeleton portion in which a plurality of arranged reinforcing cords are covered by a rubber layer. The reinforcement cords are organic fiber cords formed from polyethylene terephthalate. The organic fiber cords have an intermediate elongation (2.0 cN/dtex) of 3.0% to 4.0%, a dimensional stability index of 5.0% to 6.5%, and a difference between an elongation ratio at a strength at 70% the strength at the time of breaking and an elongation ratio at the time of breaking in a strength-elongation curve of 11% to 16%.

The invention relates to a single-ply textile support and reinforcing material (20) for articles made of rubber and/or plastic, in particular for hoses and composite materials, which is formed by means of spun yarns with very low yarn rotation (spinn alpha 0 - 10) or completely without yarn rotation preferably for knitted fabrics. The invention also relates to articles made of rubber and/or plastic, in particular hoses and composite materials, which contain the textile support and reinforcing material.

High tenacity, high elongation multi-filament polymeric tapes as well as ballistic resistant fabrics, composites and articles made therefrom. The tapes are fabricated from multi-filament fibers/yarns that are twisted together, bonded together, compressed and flattened.

The invention relates to a method of manufacturing a polyolefin multifilament yarn comprising twisting a partially drawn multifilament yarn and post-twist-drawing the twisted partially drawn multifilament yarn.

An object of the invention is to provide a cloth having water absorbency, water repellency, and a tendency to float on water, and also a textile product using the cloth. A means of resolution is to obtain a cloth using a fiber A that is not water repellent and a fiber B that is water repellent in a weight ratio (fiber A:fiber B) within a range of 50:50 to 87:13.
摘要:
A method for manufacturing a cord yarn, which has at least one filament strand, includes applying a first twist so that a K1 value has a value of 0.1837763/D1n or below, applying a second twist so that a K2 value has a value between 0.0166819/D2n and 0.3183099/D2n, and applying a third twist so that a K3 value has a value between 0.0278485/D3 and 0.2968288/D3, wherein the twists are applied so that the cord yarn has roundness of 50% or above, and when the filament is a multi filament, so that porosity between strands of the cord yarn is less than 40%.
摘要:
The invention relates to a method for making a composite material in which at least one reinforcement thread is deposited on a surface according to a path having at least one curved area on the deposition surface, wherein the reinforcement thread is connected to the surface by a polymeric binder, characterised in that a twist is applied to the reinforcement thread before the deposition thereof at least in order to compensate the length differences of the extreme paths of the thread on either side of the width as measured in a direction parallel to the deposition surface; the invention also relates to the composite materials thus obtained.
摘要:
A rubber having a fiber reinforcement embedded thereon. The reinforcement comprises a cylindrically braided cords by more than four and even numbered yarns and a center cord provided in a hollow part of it. The twist multiplier K is set lesser than 350, the twist multiplier K being expressed K=T√ D ¯ where T is a number of twists per 10cm and D is a total denier.
