Abstract

The present invention relates to a method for measuring the yarn component basing on the micropolariscope, and the method adopts the micropolariscope for detecting the fiber component of pure and blended yarn and each component ratio. The yarn sample with short segment is scattered to discrete fiber, the discrete fiber is leaded to be arranged trimly in a certain direction and is prepared to the sample piece which can be observed in the micropolariscope, the clear image of the sample piece under the micropolariscope is obtained, and the computer processes the image and outputs the fiber component style and blending ratio. The invention can accurate identify the style of the fiber comprising the yarn; can accurately detect the content proportion of each fiber component of the blending yarn; can totally realize the no-pollution testing and conforms to the basic national policy of energy saving and discharging reducing; the high-pressure electrostatic technique and computer image processing technique are adopted for realizing the automatic stock layout and automatic numbering to the fiber thereby realizing the yarn detecting with high precision and high efficiency, has low testing cost and facilitates the generalizing and applying.

Description

technical field [0001] The invention belongs to the technical field of textiles, and in particular relates to a yarn component detection method based on a polarized light microscope. Background technique [0002] Yarn is a composite of fibers. Accurately detecting the components of fibers in yarn and the content of each component is a frequently encountered problem in textile production management, product analysis and design, as well as scientific research, historical archaeology, case detection, import and export commodity inspection, etc. . At present, the detection of yarn composition is mainly through the method of appearance observation and untwisting separation observation. Due to the small size of the fiber, an optical microscope is often used to observe the longitudinal and transverse characteristics of the fiber to confirm the fiber composition. In addition, methods such as hand visual inspection, combustion, chemical dissolution, density gradient and dye coloring...
