Technical field
The invention belongs to fibrous material and its product measuring instrument field, particularly a kind of double shootings of fibrous fraction content
Head microscope test device and method of testing.It is applied to textile mills to fibre quality control and fibre quality surveillance
Law enforcement agency manages to fabric clothing fibrous fraction content inspection on market.
Background technology
Textile and clothing fabric may be made up of multiple fiber composition, and the content of various fibers directly influences textile
Wearability, with the raising of living standards of the people, cashmere class high quality fiber and its mixed material textile fabrics application day
Extensively, in mixed material textile, how many cashmere contents directly influences wearability and the price of textile fabrics to benefit, and market
The authenticity of the fibrous fraction content that the textile of upper sale is indicated, needs to test supervision by scientific method, using aobvious
Micro mirror method, to observe fiber samples longitudinal surface form or cross section shapes feature, differentiates that each fiber of counting and measurement fiber are straight
Footpath or sectional area, are the important method calculating analysis fibrous fraction content.
In microscope fibrous fraction content test method, development in recent years using image method replace traditional by micro-
The visual test of sample watched by mirror eyepiece, camera is arranged on above vertical microscope tube, sample is placed on microscope slide
Amplify through object lens on platform, focal imaging on the photosensitive unit array in camera, using image processing techniques by image presentation
In computer display screen, mobile fiber samples, by root identification and measurement fiber size, can carry out fibrous fraction content
Computer automatic analysis.
The main difficulty that MIcrosope image method test fibrous fraction content currently encounters is to observe using during colour imagery shot
Light color and colored fiber morphosis details ratio are more visible, but then do not see Chu to dull fiber sample it is impossible to distinguish dark fine
Dimension classification；Dull fiber morphosis can be seen clearly during using black and white camera, but light color and colored fiber imaging definition are poor,
Impact testing result quality.Therefore, run into dissimilar sample during test fibrous fraction content and will frequently change camera.
Moreover, if running in the same face material samples composition not only chromatic colour and light fibres but also have dull fiber, any one
Kind of camera all helpless it is impossible to meet test request.
In addition, some testing agencies, in order to avoid the frequent trouble changing camera, are just detected only with colour imagery shot.
And in checking textile during dull fiber, be necessary for carrying out in advance chemical reagent process of fading and just can see fiber surface morphology clearly
Tedious steps.But after above-mentioned process, it is inevitably generated the brought measure error of fiber size change, and examines
Survey cost and also have no reduction.
