The growth of cotton fibers can be pided into three stages: elongation stage, thickening stage, and turning stage. Cotton fiber is the main raw material of China's textile industry, and it occupies a very important position in textile fibers. Cotton cultivation is almost spread throughout China. Among them, the Yellow River Basin and the Yangtze River Basin are the main areas, along with the Northwest Inland, Liaohe River Basin, and South China, totaling five major cotton regions. The scope of cotton fiber testing includes cotton fiber, asbestos fiber, kapok fiber, rock wool fiber, cotton fiber fabric, modified cotton fiber, etc. Cotton fiber testing projects include cotton content testing, composition testing, diameter testing, length testing, fineness testing, permeability testing, strength and elongation testing, elongation at break testing, defect testing, unknown object analysis and identification, moisture regain testing, impurity content testing, maturity testing, micronaire value testing, fuzzing performance testing, linear density testing, content testing, etc
