One crucial element of the tire carcass is polyester, which is found in the form of tire cord. The tire cord affects the tire’s comfort, load-carrying performance, and durability.
It supports the load and absorbs shocks, serving as the tire’s support structure. Thermal stability is essential in this regard since the material must maintain its shape even at extremely high temperatures.
So-called HMLS (high-modulus low-shrinkage) yarns make up the tire cord. These prototype polyester goods are incredibly tear-resistant while still being incredibly elastic and temperature and size stable.
This is crucial to make sure that the tire keeps its shape even when it is underinflated and heats up more as a result of the resulting higher friction on road surfaces.
The disclosed invention includes an immersion cord constructed of the same polyester multifilament yarn that is employed as a tyre reinforcing element.
The polyester multifilament yarn has a hardness of and a difference of middle elongation percentages of not less than the inherent viscosity of the polyester, and it contains polyethylene terephthalate in an amount of not less than by mole.
The produced filament yarn and immersion cord have a balanced high elastic modulus and low contraction rate, as well as outstanding dimensional stability and fatigue resistance, making them suitable for use in tyres and other rubber products as reinforcement.
The current invention relates to a type of industrial polyester multifilament yarn with a high modulus and low shrinkage, as well as the polyfiber yarn immersion cord formed therefrom for tire reinforcement.
A type of good spatial stability, a polyester multifilament yarn with fatigue resistance, and a poly fibre yarn immersion cord made from them that can maintain itself at high temperatures are more specifically covered by the present invention.
The invention also pertains to a particular method for making the polyester multifilament yarn and poly fibre yarn immersion cord. A rubber object that is reinforced, such as a tire, is one of the applications of the typical uses that fibre had.
Nylon, polyester, artificial fibre, and other types of fibre are examples of fibres that are used as reinforcement. The molecular structure of polyester fibre, which includes a phenyl ring, is stiff.
In line with this, cotton tire cord made from polyester yarn has a high elastic modulus, a reduced amount of flat spots, and higher fatigue resistance, creep resistance, and durability.
GLOBAL AUTOMOTIVE TIRE CORD POLYESTER FILAMENT YARN MARKET SIZE AND FORECAST
The Global automotive Tire Cord Polyester Filament yarn market accounted for $XX Billion in 2021 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2022 to 2030.
As of today, Teijin Fibres Limited will begin delivering Ecopet Plus polyester fibres that have undergone chemical recycling for the cords of Toyo Tire & Rubber Proxes Ne tires, which are unique tires created for ecologically conscious passenger cars.
Teijin designed a closed-loop recycling method called Eco Circle, which will be applied to the carcass, which serves as the skeleton of a tyre, to create Ecopet Plus.
Recycled materials, according to Teijin Fibres, have previously been unable to satisfy the exacting specifications of tyre carcass fabric. However, Teijin Fibres claims that Toyo Tire & Rubber has chosen its eco-friendly Ecopet Plus due to its high quality.
There is a growth for ecologically friendly cars as a result of expanding interest in recycling, ecological product creation, and carbon dioxide reduction.
In the case of environmentally friendly car parts, particularly tires, an especially important aspect of autos, the emphasis is on creating goods that aid in reducing noise pollution, global warming, and resource consumption.
Strength, elasticity, adhesion to rubber, fatigue resistance, dimensional stability, and heat resistance are all requirements for tire cords.
Teijin Fibres claims that conventional recycling technologies have been unable to create adequate polyester fibres due to the high production requirements.
Teijin Fibres is a well-known producer and seller of polyester fibres for tyres as well as a business with extensive experience in creating goods from recycled polyester.
Utilising cutting-edge recycling techniques that chemically breakdown polyester to produce raw polyester, the company created Ecopet Plus polyester fibre.
The recycled material satisfies the exacting performance standards needed for tyre cords because it offers the purity of petroleum-derived goods.
In addition, when compared to systems that create polyester material from petroleum, Teijin Fibres’ repeated recycling technique reduces energy consumption and carbon dioxide emissions by about.
