Abstract
The invention relates to a detection method for the cross section of a fiber. The detection method comprises the following steps: 1, horizontally laying the fiber on a film, sticking two metal plates between the fiber and the film, fixing the two metal plates, drying, cooling, carrying down the fiber from the film to obtain an impression picture of the longitudinal cross section of the fiber on the film; and 2, adhering the fiber to the bottom of a container by an adhesive, adding a resin mixture to the container, drying to polymerize the resin mixture, cooling at room temperature, slicing to obtain a slice, adhering the slice to a slide glass, and putting the slide glass in cedar oil for the microscope observation. The detection method of the invention has the advantages of simplicity, no new equipment requirement, and realization of the large scale application. Compared with the direct microscope observation, the method of the invention allows the obtained field depth to be better, complete information of the cross section of the fiber to be once obtained, and influences of dyes of the surface of the fiber to be eliminated, so the discrimination accuracy on the fiber is improved.
Description
Technical field
The invention belongs to fiber and differentiate the field, particularly relate to a kind of fibre section detection method.
Background technology
Along with a large amount of development of man-made fiber, new fiber species is various day by day, except that conventional fibre, also comprises special fibre, composition fiber, modified fibre etc.For the ease of production management and product analysis, need differentiate the textile fibres science of carrying out.Fiber is differentiated and is comprised that morphological feature is differentiated and physicochemical property is differentiated.Morphological feature is differentiated microscopic examination method commonly used, utilizes the vertical and cross section shapes of microscopic examination fiber, is the basic skills of differentiating various textile fibress, and is commonly used to differentiate big type of fiber.Natural fiber respectively has special form, can correctly recognize at microscopically.For example cotton fiber vertically is flat belt-like, and natural convolution is arranged, and xsect is oval shape, and lumen is arranged; Wool vertically has curling, and there is scale on the surface, and xsect is rounded or oval, and medula is arranged in the middle of some wool; Jute vertically has horizontal joint and perpendicular line, and xsect is polygon, and lumen is bigger.
FZ/T 01057.3-2007 " textile fibres discrimination test method the 3rd part: microscopic method " points out, can adopt the vertical face and the cross section shapes of the unknown fiber of microscopic examination, and the standard photographs of control fiber and form are described the classification of differentiating unknown fiber.We can say that microscope discriminating fiber is a kind of efficient ways.For optical microscope, when jobbie in focus, the each point that not only is positioned on this plane can be seen clearly, and in the certain thickness up and down on this plane, also can see clearly Chu, and thickness of this clear part is exactly the microscope depth of field.But fibre diameter generally can reach tens microns, greater than the microscopical depth of field, therefore is difficult to the full detail of disposable acquisition fibre section.Because microscope camera lens limited size needs repeatedly to move to observe for large-area sample, the reliability of therefore observing also reduces greatly simultaneously.For fibers such as dyeing, surperficial additional information can have a strong impact on the Effect on Performance of fiber own in addition.Therefore must traditional microscopic detecting method be improved, improve the accuracy that fibre section information is obtained.
Summary of the invention
Technical matters to be solved by this invention provides a kind of fibre section detection method; This detection method is simple to operate, can obtain the better depth of field, the fibre section information that disposable acquisition is complete; Get rid of the influences such as dyestuff of fiber surface simultaneously, thereby improve the accuracy rate that fiber is differentiated.
A kind of fibre section of the present invention detection method comprises:
(1) detection of fiber longitudinal cross-section: fiber is lain on the film; With two sheet metals described fiber and film are clipped in the middle then; And with two above-mentioned sheet metals fixing after, be heated to 100～125 ℃ of dryings, be 15～30min drying time; After heating finishes, put into cooling device (like refrigerator) cooling; At last described fiber is taken off from film, can on film, obtain the impression figure of fiber longitudinal cross-section;
(2) detection of fiber cross section: fiber is being adhered to container bottom with bonding agent; And then in container, add resin compound, and being heated to 70～80 ℃ of dryings again, be 40～60min drying time; Make the resin compound polymerization; And after the cooling at normal temperatures, cut out the section that thickness is 12～18 μ m, at last gained section is bonded in and puts into cedar oil on the microslide and can carry out microscopic examination.
Film described in the step (1) is gelatin, polystyrene or polypropylene.
Bolt is used in being fixed as described in the step (1).
Described in the step (1) fixedly the time, the acting force between two sheet metals is 1.0～2.0bar.
Bonding agent described in the step (2) is a starch adhesives.
Resin compound described in the step (2) is made up of polyester resin and benzoyl peroxide, and wherein the massfraction of polyester resin is 98～99%.
Container described in the step (2) is the carton of the length of side 40～60mm.
In order to obtain fiber longitdinal cross-section diagram clearly, the amount of force on two sheet metals of clamping film and fiber is most important technological parameter, is traditionally arranged to be 1.0～2.0bar.
Beneficial effect
(1) detection method of the present invention is simple, no new equipment requirement, but scale is used;
(2) the present invention compares with microscope direct observing, can obtain the better depth of field, and the fibre section information that disposable acquisition is complete is got rid of the influences such as dyestuff of fiber surface simultaneously, thereby improves the accuracy rate that fiber is differentiated.
