Technical field
The invention belongs to weaving, fine inspection technical field, be specifically related to a kind of method that detects cotton fiber fineness and degree of ripeness, the invention still further relates to a kind of device that detects cotton fiber fineness and degree of ripeness.
Background technology
Cotton fineness is line density, refers to the quality that cotton fiber unit length has; Cotton Maturity refers to the thickening degree of fiber cell wall, and cell wall is thicker, and degree of ripeness better.
Cotton fiber fineness, degree of ripeness are the important geometric properties of cotton, and it affects cotton yarn cotton quality and spinning process, are the Main Basiss that cotton spinning is distributed cotton.Mic value is in the international cotton trade of the overall target ， of fineness degree of ripeness, to be one of valuation index.
Fineness and degree of ripeness are the important indicators that characterizes cotton physical property, to spinning process and fabric quality important.The fineness of cotton fiber is very large on yarn evenness, brute force and twist impact; The degree of ripeness of fiber is higher, and the color and luster of yarn and fabric, suction look ability and dye uniformity are higher, and elasticity is also better.
In measuring the method for cotton fiber fineness and degree of ripeness, stage casing weight method and ranking method are used for measuring cotton fiber fineness, and lumen cell wall pairing comparision, microscopic method and polariscope method are used for measuring maturity of cotton fiber.These methods have several common ground: the one, and test index is single, can only independent measurement degree of ripeness or index of fineness; The 2nd, speed is very slow, and this seems very outdated being particular about under the social background that efficiency and cost of labor improve day by day, has limited its practicality; The 3rd, repeatability is poor, and reason is that these methods are nearly all artificial, semi-artificial measurements, is affected by human factors larger.And air-flow method can only test out the mic value of cotton fiber, although air-flow method test horse cloning efficiency and repeatability can guarantee, but the grand reflection of mark testing out is the resultant effect of Cotton Maturity and fineness, cannot measure degree of ripeness and fineness index that textile enterprise is extremely concerned about.
