< p > HVI 1000 type High volume instrument abbreviation, that is, large capacity cotton fiber tester.

In 1998, at the tenth meeting of the biennial cotton inspection technology held by the International Federation of textile production, the HVI detector was recommended to the world for comprehensive evaluation and grading test.

This test began with the detection of cotton fiber properties in the United States, and later developed into a widely used fiber inspection instrument in the field of cotton production, trade and textile industry. It can detect cotton fiber maturity, fineness, sugar content, neps impurities, single fiber strength and color, classification, rapid and high-capacity detector.

< p > only put < a href= "//m.pmae.cn/news/index_c.asp" > cotton < /a > on the tester. In 30 seconds, the cotton web length, impurity grain number and equine clone are displayed on the computer screen.

Today, the XJ128 fast cotton fiber performance tester developed by Changling textile and electric company, a veteran military enterprise, has been used in batches, breaking the monopoly of foreign cotton comprehensive performance tester for many years, and saving 3% of cotton resources every year. It is another key achievement in the reform of cotton quality inspection system in 10 years.

< p > according to Pu Changcheng, deputy director of the General Administration of quality supervision, inspection and quarantine, the State Council approved the promulgation of the "cotton quality inspection system reform plan" in 2003. The national inspection and quarantine system needs a large number of < a href= "//m.pmae.cn/news/" > cotton detector > /a > (HVI). However, the tester relies on imports for a long time, the equipment price is high, the price of spare parts is high, and the supply cycle of spare parts is long, and the quality of local maintenance can not be guaranteed. At the same time, the newly revised cotton national standard will be implemented in September 1, 2013, subverting the concept of classification in the past 40 years.

< p > "the habit of habit thinking pattern formed in the past 40 years is about to change. In the past, it was based on the three conditions of comprehensive grading, while the color level was" color classification and Ze classification ".

All the cotton grading personnel in the whole industry need to relearn the inspection technology. The cotton classification laboratories and HVI testing instruments invested by the fiber inspection system should also be adjusted accordingly.

China cotton textile industry association responsible person said.

< p > Zhang Kecai, the head of China Fiber Inspection Bureau, said that before testing, the cotton grades were measured separately, and each time took about 2 hours. In order to ensure efficiency, only 100 packages of cotton were sampled for 10 bags. "This test value is not accurate, directly affects the economic benefits of the ratio of long staple cotton, and consumes a large number of cotton resources in China."

Our country produces 7 million tons of cotton per year and consums 10 million tons of cotton and has a large import volume. With the quality and cheap domestic XJ128 fast a href= "//m.pmae.cn/" > cotton fiber < /a > performance tester, it can save 3% of cotton consumption and improve the quality of Chinese cotton fabrics and the level of inspection and quarantine.
