Description
Technical field
The invention belongs to textile technology field, particularly relate to a kind of fibre sample auto arranging method based on high voltage electrostatic technique.
Background technology
Yarn constituent comprises that scientific research, trade, criminal investigation, archaeology etc. all are important test items in detecting in a lot of fields.Comparatively the Yarn constituent quantitative detecting method of widespread usage mainly contains microscopy analytic approach (optical microscopy, microscopic projector method and polarization microscope analytic approach) and chemical analysis at present.
Chemical analysis method is according to the dissolution characteristics difference of different types of fiber in certain solution, by sample to be tested being carried out a series of experiments such as weigh-dissolve-dry-weigh to analyze each component content, this method is applicable to the situation that each fibre fractionation chemical component difference is bigger, as hair/cotton, wash/cotton, hair/nitrile mixed yarn etc.; , difficultly detect as cotton/fiber crops, cashmere/wool etc. for the close raw material of chemical constitution with chemical method.For cotton fibriia, also there is chemical method in being dissolved in the finite concentration sulfuric acid solution, to cause the solution absorbency difference to carry out that blending ratio detects according to two kinds of fibers, it is 200510045527.7 that on June 21st, 2006 disclosed application number, publication number is the national inventing patent " method of testing of fiber crops/cotton blending ratio " of CN 1789977A, but this method need have cotton, the fibrilia raw material consistent with blending sample to be measured, so only be fit to the inside plants calibrating, not strong for the detection operability of commodity inspection department.Above-mentioned all chemical methodes all have low, the defect of high cost of detection efficiency, and owing to need the chemical reagent of configuration higher concentration, use in examination of fibers department at present, will produce a large amount of discarded chemical solvent, very easily contaminated environment, hazard detection personnel healths every day.
The microscopy analytic approach comprises optical microscopy, microscopic projector method and polarization microscope method.Optical microscopy is differentiated fiber according to different types of fiber difference vertical, laterally morphological feature; The microscopic projector method is mainly used in the detection that detects the tangible fiber of cross-sectional diameter difference in size and carry out fibre finenesses such as wool; The polarization microscope method is according to the birefraction difference of different types of fiber, or carries out fiber according to the phenomenon of fiber expression characteristics color under polarization microscope and differentiate.Above-mentioned three kinds of microscopy methods are extracted the sample of some and it are separated into staple in bulk from blending product, and each fibre fractionation is differentiated, counted, and the diameter of each component fibre of test some, thereby calculate blending ratio.Close for composition, be difficult to each fibre fractionation with the chemical method discriminating, as cotton/fiber crops, wool/cashmere, Tencel/ viscose glue or the like, adopt above-mentioned microscopy method to carry out qualitative analysis and detection by quantitative to blending product more exactly, simultaneously, because of said method all is the physical detection process, do not relate to pollution problem, so the microscopy analytic approach is considered to the most promising yarn qualities detection method, representing the developing direction of modern textile product detection technique, use more prevalent.
Yet, although the microscopy method has advance and application prospect preferably,, also need survey the diameter of up to a hundred fibers because need to reach thousands of by root discriminating and counting fiber, workload is very big, and this has limited the popularization and application of this method.The main cause that causes this problem is fiber to be measured stochastic distribution in field of view, and orientation is mixed and disorderly, makes testing staff's fatiguability in to the discriminating of a large amount of fibers, counting process, and inefficiency reduces accuracy of detection.The best approach that addresses this problem is to realize the auto arrangement of fiber samples to be measured.At present, still adopt the mode of hand carding fiber arranged in fibre inspection department and universities and colleges, factory, laboratory, as using microscopic projector to carry out in fibre diameter and the composition detection, the fiber arranged sample of mode by hand always.
