How to make good use of HVI 1000 large-capacity cotton fiber tester? Please tell me.

According to the analysis of China Textile Machinery Industry Association, the current situation of textile testing instruments is: the development level of domestic instruments is slow.

The level of large-capacity cotton fiber detection instruments has been improved. Swiss Hurst Company exhibited HVI 1000 high-capacity cotton fiber tester for the first time. Its operation menu is Chinese display interface; The length and strength modules are sampled by double samplers, which improves the testing efficiency. The color module adopts xenon lamp light source and adopts flash test method to prolong the service life of light source and enhance the stability of test results. In addition, the instrument can directly measure the moisture content of fibers in the test area to correct the measurement results of length and strength. The ART detector of Primay Company in India rechecks the length and strength with samples that have been tested for color and impurities, which improves the detection efficiency of the whole system. The company's aQura detector uses the principle that one end of cotton fiber is neat and then the distribution length is measured to measure the short fiber rate. XJ 120 fast cotton fiber performance tester developed by Changling Textile Power Company fills the blank of HVI products in China.

Although the products on display are still sampled manually in the length and elongation measurement module, the sampling fineness, calibration method, color and impurity sample placement structure have been improved, and the stability of the measurement results has been improved. In addition, the software modules of cotton bale management system and automatic cotton blending system are added, which enhances the functions of the products and is convenient for users to use.

Hairiness tester has made new development. The LST-V yarn hairiness diameter tester exhibited by Nissin Instrument Industry Co., Ltd. uses two sets of laser collimated light sources to measure the hairiness and diameter respectively, which can give the hairiness index and the number of hairiness of different lengths at the same time. The number of hairiness is determined by projection counting method, and the number of hairiness greater than 1 mm, 3 mm or 5 mm is counted respectively, which is very distinctive. The hairiness test head on PREMIERTESTERTM7000 capacitive yarn evenness tester of India Preme Company also adopts projection counting method, which can measure the hairiness of different lengths. Seven domestic manufacturers exhibited yarn hairiness tester. Among them, Beijing Huahao Electronics Co., Ltd. uses the shading amount of hairiness to calculate the hairiness index, and other manufacturers use the projection counting method; Changling Textile Power and Suzhou Changfeng Textile Electromechanical Technology Co., Ltd. adopt direct shading counting; Laizhou Electronic Instrument Co., Ltd., Taicang Hongda Textile Instrument Co., Ltd. and Changzhou Dahua Electronic Instrument Co., Ltd. adopt optical magnification projection shading counting, and the yarn path basically adopts the inner edge. The yarn path of Y 17 1L yarn hairiness tester of Laizhou Electronic Instrument Co., Ltd. absorbed the advantages of foreign instruments, and added a yarn tension measurement display device, which improved the accuracy and consistency of the test.

Many new breakthroughs and new products appeared at the exhibition. The UltraScanPRO color measuring instrument of huntly color technology management company in the United States has solved many color measuring problems in the industry, such as dark color and high chroma. The company's ColorQuestXE colorimeter has advantages over the mainstream configurations and products on the market in terms of color measuring band, measuring wavelength interval, light source, detector and ultraviolet function. Fabric surface effect tester is a new product unveiled at this exhibition. Opt 1- grade. The E-T fabric surface effect evaluator of Roches International Company in the UK is an instrument developed by Roches International Company in cooperation with Martha's Company in the UK and Senkal University to evaluate the fabric surface effect, such as hairiness effect and crochet effect grade. In addition, the new technology of digital image analysis system also appeared in the exhibition. The DigiEye digital image analysis system of SDLATLAS is a non-contact digital image analysis system, which can be used for automatic color fastness rating and color measurement, and can be displayed on a calibrated display screen or printed by a printer. With special software, the DigiEye model can provide automatic color fastness grading.

The instruments exhibited by foreign manufacturers are mainly high-end instruments, which is the weakness of domestic instruments. For example, Huste exhibited the latest UT-5 capacitive yarn evenness tester, HVI 1000 tester, high-speed strength machine, electronic yarn cleaner with white foreign fiber removal function, and brought the Huste 2007 statistical bulletin. However, the textile instrument manufacturing industry in China is gradually expanding, and the varieties of textile instruments are constantly improving. The testing instruments required by various industries and processes such as fiber, yarn, weaving, printing and dyeing, finishing and clothing are basically produced. The popularization and application of computer and electrical measurement technology has promoted the development and quality improvement of textile instruments in China. China's conventional textile instruments, especially yarn testing instruments, have basically met the needs of the development of China's textile industry. China has started to develop high-end textile instruments, and new products are constantly introduced, so it needs to speed up the pace of catching up with the advanced world level.

The development of high-end instrument testing technology and textile instruments in China is not fast. For example, fast single fiber measurement technology, on-line cloth inspection technology and color testing are still relatively weak. The development of musical instrument categories is also uneven. For example, chemical fiber testing instruments are the weak link, while other instruments such as clothing and styles are few, and color instruments are almost blank. The new instrument lacks verification regulations and calibration specifications, and some of the original verification regulations and calibration specifications have fallen behind, or failed, or need to be revised urgently.
