Description
Technical field
The present invention relates generally in weaving, the fine inspection industry, measures the electronic device of cotton fiber fineness and degree of ripeness.
Background technology
Degree of ripeness and fineness are the important indicators that characterizes the cotton physical property, to spinning process and fabric quality important.The degree of ripeness of cotton 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; The fineness of fiber is also very large on yarn evenness, brute force and twist impact.Test method about the maturity of cotton fiber fineness in the Cotton in China standard (is measured degree of ripeness such as polariscope, microscope, air-flow method; Weigh in the stage casing, ranking method is measured fineness etc.) test index is single, can't provide simultaneously degree of ripeness and fineness, and speed is very slow, poor repeatability, be difficult to apply.Now have a lot of employing air-flow first compression methods to measure the instrument of mic value both at home and abroad, measurement result only is mic value, can only reflect the resultant effect of maturity of cotton fiber and fineness.
The instrument that adopts at present air-flow second-compressed measurement cotton fiber fineness to close degree of ripeness both at home and abroad has several families, but have all that sample mass is low, mass range is little or the automaticity one or more problem of senior middle school not, be difficult to adapt to current fiber detect industry fast, simple applicable trend.
Summary of the invention
The object of the invention provides a kind of method and device of measuring large capacity cotton fiber degree of ripeness and fineness, detects quick, the simple applicable trend of industry to adapt to current fiber.
The method of a kind of large cubic content measurement cotton fiber degree of ripeness and fineness, it is to realize in accordance with the following steps:
(1) produces sample: put in the test specimen tube that shredding is good, the given mass cotton fiber sample of cleaning, disordered orientation, successively be compressed into two kinds of different fixed volumes, form fiber multihole plug sample;
(2) sample Pressure Drop test: measure sample gas penetration potential under different compressive states, under each compressive state, air-flow passes through sample with target flow, the detection relevant pressure falls, obtain two Pressure Drops, a pine presses the Pressure Drop of fiber plug sample to represent that with PL another Pressure Drop that presses the fiber plug sample represents with PH;
(3) adopt fineness, mature fibers percent, degree of ripeness ratio and the mic value that obtains cotton fiber with following model algorithm:
Mark is grand: Mic=0.70+710/ (PL+40);
Fineness: LD=54000/PL * (PH/PL)
1.75
Degree of ripeness ratio: M=0.196 * PL
0.125* (PL/PH)
2
Mature fibers percent: PM=86.0 * PL/PH-52.4.
Realize a kind of large cubic content measurement cotton fiber degree of ripeness of above-mentioned measuring method and the device of fineness, comprise with the constant source of the gas of the changeable flow of flow controller control, be used for the pressure gauge that relative pressure is measured, have the test barrel of hollow cylindrical test cavity; Sample compression set (3) is housed on the test barrel, and constant source of the gas passes into test barrel by flow controller and control module, Access Control unit after pressure gauge links to each other with master processor.
The inventive method and device can measure large capacity (the degree of ripeness fineness of cotton fiber under 10 ± 0.5g) conditions, test mass is large, and is representative strong; Have the quality debugging functions and can guarantee in the certain mass scope, test result consistent; Mathematical model is used for calculating fineness and the degree of ripeness of cotton fiber.
