Used for measuring and analyzing yarn hairiness indexes, automatic test 
	and statistical analysis on the length, quantity and distribution of feathers. 
	
	
	1.The test method adopts the projection counting method, which conforms 
	to the national textile industry standard. 
	2.The detection system adopts digital camera technology, which is composed 
	of industrial grade image sensor, optical imaging system and new high-speed 
	single-chip microcomputer. 
	3. Optical imaging technology brings clear image and micron level image 
	sensor, which makes the length of the test feathers more accurate. 
	4. From the test to the whole process of data processing digitalization, the 
	realization of the real digital feather instrument. 
	5. Adopt new technology and support to closed-loop automatic adjust test 
	parameters to make testing condition more stable, so that this instrument 
	has the advantages of good stability, consistency.
