(Donghua National University Science Park)

Located at Donghua National University Science Park in Lane 365 of Shanghai Xinhua Road, the Shanghai New Fiber Instrument Co., Ltd. & Donghua Lipu Instrument Research Center has been developed from the long period cooperation of production, study, and research on textile measurement technology and instrument with Donghua University (the former China Textile University). Through years of exploring and practicing, a series of testing apparatus characteristic of advanced technology, high stability, and credit in market have been developed. These apparatus have been widely used in large synthetic fiber manufacturers, municipal and provincial fiber-testing inspection bureaus, entry-exit inspection and quarantine bureaus, and fiber research institutes. The apparatus developed by this center can be found everywhere in China, covering the large areas from Neimeng and Xinjiang provinces to Hainan province and Shenzhen city. And the quality of the apparatus has been recognized by the public. In addition, in recent years, the apparatus have been adopted by foreign enterprises.

Led by Prof. Li Ruqin (PhD. tutor), the research center (company) has gained great achievements in discipline constructing and science researching on textile measurement technology, especially in developing the fiber tensile tester. The XQ-1 Fiber Tensile Tester is one of the most widely used instruments in fiber production and investigation by synthetic fiber enterprises. If the XQ-1 Fiber Tensile Tester connects with the XD-1 Fiber Fineness Tester, it can measure some important indices of the fiber, such as the strength, elongation, linear density, tenacity, modulus, force at definite elongation, and specific work of the fiber, etc. The computer can display the force-elongation curve while the fiber sample is being extended and save the measured data. The XQ-1 Fiber Tensile Tester can also be used to measure the wet modulus of rayon fiber, the tensile property of the high-tenacity high modulus aramid fiber, carbon fiber, mental fiber, glass fiber, engineering staple fiber, and the pre-oriented fiber for the quality control during the production process. The recently developed new instrument, XH-1 Fiber Thermal Shrinkage Tester and XCP-1 Fiber Crimp Elasticity Tester, update the traditional measuring method and mode. With the advanced digital-based technology they can measure the thermal shrinkage and crimp ratio of the fiber quickly and precisely. The apparatus are finely constructed and can be operated with high automation, and will be widely used in the textile industry. As mentioned above, a series of patent products, composed of the XQ-1 Fiber Tensile Tester, XD-1 Fiber Fineness Tester, XH-1 Fiber Thermal Shrinkage Tester, XCP-1 Fiber Crimp Elasticity Tester, and XQ-1B Pre-oriented Fiber Tensile Tester, come to the new advanced synthetic fiber measuring system. They provide a modern measuring method for objectively and precisely examining and evaluating fiber qualities, and for effectively controlling the chemical fiber production. They also provide an important means for the enterprise to improve their management, build their own brand, and increase their competitive ability in the market.

XQ-1, XD-1 – Computer Combination

 The XD-1 Fiber Fineness Tester measures the linear density of the fiber sample first, then the tensile test of the same fiber is carried out by the XQ-1 Fiber Tensile Tester. Hence, through the measured results of the two apparatus, the strength per unit linear density——the fiber tenacity is calculated. At the same time, some other indices are obtained, including the fiber strength, elongation, force at definite elongation, modulus, and specific work of the fiber, etc. This kind of fiber tensile test can eliminate the influence on the measured results by sampling errors. Therefore, it is recommended by the international organization for standardization as the priority method of fiber tensile test.
