The origin and development process of modern textile testing technology

The carrier of textile testing technology is textile testing equipment. In recent decades, textile testing equipment has made great progress in testing mechanism, mechatronics level, microcomputer application, testing indicators, and types of testing equipment. A batch of capacities have emerged. A new type of mechatronics instrument with large, intelligent, multi-function and high degree of automation. The introduction of these new instruments marks that textile inspection technology has reached a new level. The development of modern textile inspection technology and information technology has greatly promoted the progress of textile inspection technology. The application of computer technology, automation technology and communication technology in the field of textile inspection has greatly improved the means and capabilities of modern textile inspection. At present, the functions of textile testing equipment are becoming more and more perfect, and the intelligence and automation of the instruments are getting higher and higher. Using advanced equipment, people have been able to change from the inspection of the performance of traditional raw materials to the inspection and prediction of the performance of fiber and yarn. the quality of. Looking at the development of modern textile inspection technology, it presents the following main characteristics. 1. Maximize the level of automation of testing. With the ISO 1973-1995 'Determination of Textile Fiber Linear Density, Weighing and Vibration MethodThe vibrating fineness meter does not require manual adjustment or visual observation of the maximum value of fiber vibration. It can provide automatic testing of fiber linear density with a single key operation. Because no human judgment is required. Thereby improving the accuracy of the fiber linear density value. Two operators operate the cotton fiber large-capacity testing system. It only takes 1h to complete the test of 180 samples. The system test result is not affected by the operator. The results come from a large number of samples, and the more representative test results have better accuracy and reproducibility. 2. Extensive application of high and new technology. (1) Wide application of computer technology: a new type of computer-controlled rapid airflow method for measuring the linear density of raw cotton and wool, which is newly launched in the world, only needs 3g～5g fiber sample, which eliminates the time waste of controlling the sample to the fixed weight. And the error of the sample itself. In the single fiber strength and elongation test, the new instruments all use computers for data collection, processing and display. The settings such as the gauge length and elongation at break can be adjusted in advance through the computer software within the design range. At present, foreign countries are using computer backbone network and near-infrared spectrophotometry to identify fibers. The spectrum generated by the near-infrared spectrophotometer is further analyzed through the computer backbone network to generate the ASCl file of the absorption spectrum. This method is fast and reliable. The central network can not only distinguish fibers of similar chemical composition, but also identify the blending composition of fibers. (2) Application of digital image processing technology: Optical fiber diameter analyzer (OFDA) uses digital image processing technology to determine the average diameter and diameter distribution of wool fibers, which can test 10,000 fibers per minute. The greatest value of OFDA is not only to test fiber diameter and diameter distribution, but also to test medullary hair, dead hair and fiber curl. (3) Application of laser technology: Australia's laser scanner (Sirolan) is used for rapid measurement of wool fiber diameter like 0FDA, the difference is that it uses laser scanning and computer control technology, using the thickness of fiber diameter and silicon photocells. Linear correlation of the detected laser energy attenuation. Complete the entire test process within a few minutes. And print out the average fiber diameter, effective root number and its distribution map. 3. Sensing methods and grippers continue to get [advanced]. The textile testing instrument has developed from capacitive sensing to i-frequency sensing and photoelectric sensing. Germany Zweigle (Zweigle) company's G580 uniformity e tester has two independent testing devices. }A test device contains an audio room. The air vibration frequency is 3Hz～5Hz. Using the correlation between the sound frequency change of the fiber and the variable speed and the uniformity of the fiber bundle, it can continuously measure the sliver and the thick linear density and the uniformity. The test results are not affected by the surrounding environment. Zweig's G580 yarn structure e-inspector uses Barco optical sensors to measure yarn structure data instead of weight: 2 ram per scan. Infrared test results are not affected by the mixing of test materials and the ambient atmosphere; this improves the accuracy of the test.
