Toray Industries, Inc. (東レ株式会社, Tōre Kabushiki-gaisha) is a multinational corporation headquartered in Japan that specializes in industrial products centered on technologies in organic synthetic chemistry, polymer chemistry, and biochemistry.
Its founding business areas were fibers and textiles, as well as plastics and chemicals. The company has also diversified into areas such as pharmaceuticals, biotechnology and R&D, medical products, reverse osmosis bigmembranes, electronics, IT-products, housing and engineering, as well as advanced composite materials.
The company is listed on the first section of Tokyo Stock Exchange and is a constituent of the TOPIX 100and Nikkei 225 stock market indices.
Toray Industries had been originally established as Toyo Rayon in 1926 by Mitsui Bussan, one of the two largest Japanese trading companies (sogo shosha) of the time (the other being Mitsubishi Shoji). The fact that Mitsui did not allow the company to be named as a Mitsui company indicates their skepticism of the risk on the business. Risk arose from the fact that, when it was established, the company did not have the right technology to produce Rayon. It had approached Courtaulds and then Du Pont to buy the technology but, because the price was too high, it decided to buy equipment from a German engineering company and hire about twenty foreign engineers to start the operation.
When Nylon was invented in 1935 by Wallace Carothers of DuPont, Toray immediately got hold of a sample product through the New York City branch of Mitsui Bussan, and started research by dissolving this sample in sulfuric acid. Because of the patent protection, the company had to make its own effort to synthesize polyamide and make fibre out of it. In 1941, just three years after Du Pont's announcement of nylon, Toray completed the basic research on nylon and started building a small plant to produce Nylon 6. The operation started in 1943 and the product was sold, mainly to make fishing nets.
In 1946, following the end of World War II, Du Pont requested an investigation by GHQ (the General Headquarters of Allied Powers) of Toray's infringement of Du Pont's nylon patents but GHQ found no evidence of infringement, certifying that Toray's nylon technology was its own.
Toray is currently the world's largest producer of carbon fiber, and Japan's largest producer of synthetic fiber.Its carbon fiber is extensively used in exterior components of the Boeing 787 airliner.
In 2014, as a major aerospace composites supplier, Toray opened a polyacrylonitrile (PAN), the carbon fiber precursor, production line in Lacq, south-western France.
In 2013, Toray acquired an approximately 13% stake in Spectral Diagnostics, a Canadian pharmaceutical company focused on sepsis.
In March 2018, Toray announced it would acquire TenCate Advanced Composites to advance carbon fiber production capabilities.
Kevlar is a heat-resistant and strong synthetic fiber, related to other aramids such as Nomex and Technora. Developed by Stephanie Kwolek at DuPont in 1965, this high-strength material was first used commercially in the early 1970s as a replacement for steel in racing tires. Typically it is spun into ropes or fabric sheets that can be used as such or as an ingredient in composite material components.
Nylon is a generic designation for a family of synthetic polymers, based on aliphatic or semi-aromatic polyamides. Nylon is a thermoplastic silky material that can be melt-processed into fibers, films, or shapes. It is made of repeating units linked by amide links similar to the peptide bonds in proteins. Nylon polymers can be mixed with a wide variety of additives to achieve many different property variations. Nylon polymers have found significant commercial applications in fabric and fibers, in shapes, and in films.
Fiber or fibre is a natural or man-made substance that is significantly longer than it is wide. Fibers are often used in the manufacture of other materials. The strongest engineering materials often incorporate fibers, for example carbon fiber and ultra-high-molecular-weight polyethylene.
Carbon fibers or carbon fibres are fibers about 5 to 10 micrometers (0.00020–0.00039 in) in diameter and composed mostly of carbon atoms. Carbon fibers have several advantages including high stiffness, high tensile strength, low weight, high chemical resistance, high temperature tolerance and low thermal expansion. These properties have made carbon fiber very popular in aerospace, civil engineering, military, and motorsports, along with other competition sports. However, they are relatively expensive when compared with similar fibers, such as glass fibers or plastic fibers.
E. I. du Pont de Nemours and Company, commonly referred to as DuPont, was an American company that was founded in July 1802 in Wilmington, Delaware, as a gunpowder mill by French-American chemist and industrialist Éleuthère Irénée du Pont de Nemours.
Synthetic fiber or synthetic fibre are fibers made by humans through chemical synthesis, as opposed to natural fibers that are directly derived from living organisms. They are the result of extensive research by scientists to improve upon naturally occurring animal and plant fibers. In general, synthetic fibers are created by extruding fiber-forming materials through spinnerets, forming a fiber. These are called synthetic or artificial fibers. Synthetic fibers are created by a process known as polymerization, which involves combining monomers to make a long chain or polymer. The word polymer comes from a Greek prefix "poly" which means "many" and suffix "mer" which means "single units".. There are two types of polymerization: linear polymerization and cross-linked polymerization.
Aramid fibers are a class of heat-resistant and strong synthetic fibers. They are used in aerospace and military applications, for ballistic-rated body armor fabric and ballistic composites, in marine cordage, marine hull reinforcement, and as an asbestos substitute. The name is a portmanteau of "aromatic polyamide".
Mitsui Group is one of the largest keiretsu in Japan and one of the largest corporate groups in the world.
Sumitomo Corporation is one of the largest worldwide Sogo shosha general trading companies, and is a diversified corporation. The company was incorporated in 1919 and is a member company of the Sumitomo Group.
Stephanie Louise Kwolek was an American chemist who is known for inventing Kevlar. She was of Polish heritage and her career at the DuPont company spanned more than 40 years. She discovered the first of a family of synthetic fibers of exceptional strength and stiffness: poly-paraphenylene terephthalamide.

Carbon fiber reinforced polymer, Carbon fibre reinforced polymer, or carbon fiber reinforced plastic, or carbon fiber reinforced thermoplastic, is an extremely strong and light fiber-reinforced plastic which contains carbon fibers. The spelling 'fibre' is typically used outside the US. CFRPs can be expensive to produce, but are commonly used wherever high strength-to-weight ratio and stiffness (rigidity) are required, such as aerospace, superstructures of ships, automotive, civil engineering, sports equipment, and an increasing number of consumer and technical applications.
