東麗工業(yè)
東麗工業(yè)公司 (東レ株式會(huì)社)是一家總部位于日本的跨國(guó)公司,專門(mén)從事以有機(jī)合成化學(xué)、高分子化學(xué)和生物化學(xué)技術(shù)為中心的工業(yè)產(chǎn)品。
其創(chuàng)始業(yè)務(wù)領(lǐng)域是纖維和紡織品,以及塑料和化學(xué)品。公司還涉足制藥、生物技術(shù)和研發(fā)、醫(yī)療產(chǎn)品、反滲透大膜、電子、IT產(chǎn)品、住宅和工程以及先進(jìn)復(fù)合材料等領(lǐng)域。
該公司在東京證券交易所第一部上市,是 TOPIX 100 和日經(jīng) 225 股票市場(chǎng)指數(shù)的成分股。
歷史
東麗工業(yè)最初由當(dāng)時(shí)日本兩大貿(mào)易公司 (sogo shosha) 之一(另一家是三菱商事)三井物產(chǎn)于 1926 年成立,前身為東洋人造絲。三井物產(chǎn)不允許將該公司命名為三井公司這一事實(shí)表明他們對(duì)業(yè)務(wù)風(fēng)險(xiǎn)持懷疑態(tài)度。風(fēng)險(xiǎn)源于這樣一個(gè)事實(shí),即當(dāng)公司成立時(shí),該公司沒(méi)有合適的技術(shù)來(lái)生產(chǎn)人造絲。它曾先后與 Courtaulds 和 Du Pont 接洽以購(gòu)買(mǎi)這項(xiàng)技術(shù),但由于價(jià)格太高,它決定從一家德國(guó)工程公司購(gòu)買(mǎi)設(shè)備,并雇用大約 20 名外國(guó)工程師來(lái)開(kāi)始運(yùn)營(yíng)。
1935 年,杜邦公司的 Wallace Carothers 發(fā)明了尼龍,東麗立即通過(guò)三井物產(chǎn)的紐約分公司獲得了一份樣品產(chǎn)品,并通過(guò)將此樣品溶解在硫酸中開(kāi)始了研究。由于專利保護(hù),該公司不得不自己努力合成聚酰胺并制造纖維。1941 年,在 Du Pont 宣布推出尼龍僅三年后,Toray 完成了尼龍的基礎(chǔ)研究,并開(kāi)始建造一家生產(chǎn)尼龍 6 的小型工廠。該業(yè)務(wù)始于 1943 年,產(chǎn)品被銷售,主要用于制作漁網(wǎng)。
1946 年,第二次世界大戰(zhàn)結(jié)束后,杜邦要求 GHQ(盟軍總司令部)對(duì)東麗侵犯杜邦尼龍專利的行為進(jìn)行調(diào)查,但 GHQ 沒(méi)有發(fā)現(xiàn)侵權(quán)證據(jù),證明東麗的尼龍技術(shù)是自己的。
東麗目前是世界上最大的碳纖維生產(chǎn)商,也是日本最大的合成纖維生產(chǎn)商。[7]其碳纖維廣泛用于波音 787 客機(jī)的外部部件。
2013 年 9 月,東麗工業(yè)宣布計(jì)劃以五億美元收購(gòu) Zoltek。該公司成為 Toray 的全資子公司,并繼續(xù)作為獨(dú)立的業(yè)務(wù)部門(mén)運(yùn)營(yíng)。
2014 年,作為主要的航空航天復(fù)合材料供應(yīng)商,東麗在法國(guó)西南部的拉克開(kāi)設(shè)了一條聚丙烯腈 (PAN) 生產(chǎn)線,即碳纖維前體。
2017 年 11 月,東麗承認(rèn)在 2008 年至 2016 年期間犯下了 149 次質(zhì)量數(shù)據(jù)造假行為,包括對(duì)輪胎加強(qiáng)簾線進(jìn)行的測(cè)試。作為東麗的客戶,波音和優(yōu)衣庫(kù)公司可能已經(jīng)受到影響。

2013 年,東麗收購(gòu)了 Spectral Diagnostics 約 13% 的股份,這是一家專注于膿毒癥的加拿大制藥公司。
2018 年,東麗宣布將收購(gòu) TenCate Advanced Composites,以提高碳纖維生產(chǎn)能力。
Toray Industries
Toray Industries, Inc. (東レ株式會(huì)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 big membranes, 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 100 and Nikkei 225 stock market indices.
History
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 September 2013, Toray Industries announced a plan to buy Zoltek for half a billion dollars. The company became a wholly owned subsidiary of Toray and continued operating as a separate business unit.
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 November 2017, Toray admitted to committing 149 quality data falsifications between 2008 and 2016, including on tests run on tire-strengthening cords. As clients to Toray, the companies Boeing and Uniqlo may have been affected.
Operations
The world headquarters is in the Nihonbashi Mitsui Tower, 1-1, Nihonbashi-Muromachi 2-chome, Chūō, Tokyo, Japan
Toray has operations in 20 countries and regions: Japan, Mainland China, Hong Kong, Taiwan, South Korea, Indonesia, Malaysia (Penfibre SDN Berhad), Singapore, Thailand, India, Czech Republic, France, Germany, Italy, Netherlands, Switzerland, United Kingdom, Mexico, and the United States
In 2013, Toray acquired an approximately 13% stake in Spectral Diagnostics, a Canadian pharmaceutical company focused on sepsis.
In 2018, Toray announced it would acquire TenCate Advanced Composites to advance carbon fiber production capabilities.
