Important content of the reform of the physical examination of cotton

It is understood that compared with the original standard, the newly revised national standard "cotton fine cotton and cotton" as early as September 1, 2013, the revised standard changes involve as many as 21 items, in which the abolition of the grade and implementation of the color grade is the standard. The core content is also an important measure for the integration of fiber testing systems with international standards. It is also an important part of China's cotton quality inspection system reform.

After the newly revised cotton national standard implements the cotton color grading system, it will fully implement the instrument-by-package inspection of large bales into bales for cotton so as to fully realize the scientific and objective assessment of the inherent quality of cotton and promote the optimal allocation of cotton resources in China. And make full use of it, promote industrial upgrading, technological progress, reduce textile costs, improve textile quality, and promote the development of the cotton textile industry.

Xu Shuibo, chief engineer of the China Fiber Inspection Bureau, said that the main purpose of studying the cotton color grading system is to split the current “three conditions” of cotton grades, namely, maturity level, color characteristics, and the quality of the rolling mills, so as to meet the requirements for large bales. All kinds of quality indicators of cotton need to be instrumented. Whether it is possible to abolish cotton grade inspection as soon as possible and smoothly implement the cotton color grading system is related to whether the cotton quality instrumentation inspection index system and inspection method can be fully integrated with international practices.
