Abstract
The invention belongs to the technical field of textile testing and particularly relates to a method for quickly and qualitatively discriminating fibers. The method comprises the following steps: firstly, putting fibers to be tested on a glass slide and covering with the cover glass; secondly, observing the longitudinal morphological characteristics of an obtained sample under a projection microscope, and dropping a reagent such as hydrochloric acid, concentrated nitric acid or glycerin on the glass slide to observe the fiber change so as to discriminate the fibers. The whole discriminating process is quick and accurate, the problem of relatively low qualitative discriminating speed of common fibers in a textile fiber content test process is solved, and the labor intensity of testers is reduced.
Description
Technical field
The invention belongs to textile test technical field, be specifically related to a kind of method that fast qualitative differentiates fiber.
Background technology
Textile fibres is the important source material taking textile, household textiles and fabrics for industrial use, in production and daily life, fiber understood by which kind of fiber is, fabric is planted fiber spinning by which kind of or which and is made, you can be made to grasp the performance of fiber and textile better, and this is to normally to produce and daily life has very important meaning.The kind of textile fiber is a lot, and along with a large amount of development of man-made fiber, the textile of blending and intertexture is also increasing, and the performance of textile is closely related with the fibre property of this textile of composition.Therefore, in textile production management or product analysis, differentiate just even more important to fiber science of carrying out.The mode of appearance of various textile fiber or inwardness have similar place, also have difference.Fibre identification utilizes fiber appearance form or inwardness difference exactly, adopts various method that they are made a distinction.The phase difference of various natural fiber is comparatively obvious, and of a sort phase keeps certain substantially.Therefore, differentiate that natural fiber is mainly according to outward appearance phase Characteristics.The mode of appearance basic simlarity of many man-made fiber particularly general synthon, its cross section mostly is circular, but along with the development of profile fibre, the man-made fiber of one species can be made into different section morphologies, this is just difficult to distinguish fiber species from phase Characteristics, therefore must differentiate in conjunction with additive method.Because the material the Nomenclature Composition and Structure of Complexes of various chemical substance is different, their physical property difference is very large.Therefore, man-made fiber is mainly differentiated according to fibrous physics and chemical property difference.
Differentiate that the method for fiber has microscopic examination method, combustion method, dissolution method, coloring medicine method, melting point method, densimetry and By Birefringence Method etc.In addition, also fiber can be differentiated according to fibrous molecular structure, as X-ray diffraction method and infrared absorption spectroscopy etc.
At present, using maximum is microscopic method and dissolution method.These two kinds of methods are that the basis being based upon feel ocular estimate and combustion method is empirically carried out, and general fibre common at present, finally can be differentiated it by these two parts.But these two kinds of methods also come with some shortcomings, such as microscopic method, conventional is biological microscope, the film-making process (particularly cross-sectional slices) of fibre section is more loaded down with trivial details, human eye is needed to go to observe the fiber on microslide by eyepiece, visual field opereating specification is more limited, and microscopic method qualitative progress needs to spend many time to go to distinguish fiber.Dissolution method, be the method differentiating fiber on the basis of microscopic method further, carry out separately with regard to current technical needs, course of dissolution needs about 5 minutes, and some also may need heating.The discriminating time is long and loaded down with trivial details.
Summary of the invention
In order to solve the problem, the object of the invention is to, provide a kind of simple to operate, the fast qualitative that qualification accuracy rate is high differentiates fiber process.
The present invention is achieved through the following technical solutions:
Fast qualitative differentiates a method for fiber, comprises following preparation process:
A. prepare hydrochloric acid and red fuming nitric acid (RFNA), be placed in different reagent bottles respectively;
B. get appropriate fiber to be measured to be placed on microslide, and covered;
C. be first placed on the glass objective table of projection microscope by the microslide with fiber to be measured, under amplifying 100 ~ 500 times of conditions, mobile microslide makes fiber be projected on screen, observes the form of fiber, and tentatively identifies fiber;
D. in reagent bottle, get described hydrochloric acid drops in fiber to be measured, and covered observes state change and the situation of dissolving of fiber;
E. finally on fiber to be measured, instill described red fuming nitric acid (RFNA), observe state change and the situation of dissolving of fiber, indulge face morphological feature with the standard of microscopic method and contrast, qualitative judgement fibre property.
Wherein, projection microscope adopts Wuxi optical instrument manufacturing plant, JTT/D type, projection microscope.
Preferably, the concentration of volume percent of described hydrochloric acid is 20%.
Preferably, the concentration of volume percent of described red fuming nitric acid (RFNA) is 65% ~ 68%.
Preferably, in described step C, if observed bast-fibre, then separately get a sample instillation glycerine and determined bast-fibre further.
Preferably, before described steps A, feel ocular estimate and combustion method tentatively judge.
Preferably, described fiber to be measured is animal wool fiber, regenerated celulose fibre, polyamide fibre, acrylic fibers, CUP, acetate fiber, Populus deltoides cotton, bast-fibre, silk, dacron or some snapback fibre.
Preferably, described animal wool fiber is wool, cashmere, the rabbit hair or mohair yarn etc.
Preferably, described regenerated celulose fibre is sticky fibre, Modal or lyocell.
Preferably, described snapback fibre is again for being spandex, polyolefin elastic fiber, elastodiene fibre (rubber) etc.
The present invention utilizes simple reagent (glycerine, 20% hydrochloric acid, red fuming nitric acid (RFNA)) to process fiber to be measured successively by described method, and under projection microscope observation period longitudinal morphological feature, carry out qualification to fiber to judge, wherein under 20%HCl normal temperature, volatility is little, can dissolve polyamide fibre; The concentration of red fuming nitric acid (RFNA) is 65.0 ~ 68.0%, and under normal temperature, solubilized acrylic fibers, silk, vinegar fibre etc., can make wool fibre expand.The present invention first drips hydrochloric acid, then drips red fuming nitric acid (RFNA), and can make wool fibre undergoes rapid expansion after two acid mixing, the some dyes that can destroy on fiber reaches the object of fading, and regenerated celulose fibre can be made to become more penetrating, is more conducive to observing fibre morphology.Whole qualification process is fast (only needing 1 ~ 2 minute) not only, and accurately, solve problem slow to common fiber Qualitive test in textile fiber content test process, reduce the labour intensity of tester simultaneously.
