Problems solved by technology

It is necessary to measure hundreds or even thousands of fibers, which will cause eye fatigue and errors
[0004] (2) Distinguishing fibers according to fiber shape is easily affected by subjective factors and requires personnel with a high professional level to operate
[0005] (3) Because this method ignores the lumen structure of the fiber and regards the fiber as a cylinder, there is a large error in the method itself

Embodiment Construction

[0026] The present invention is based on Raspberry's theory that "when binary substances are dissolved in the same solution, there is a certain relationship between their concentrations", the dissolved concentration of hemp and cotton fiber in the same solution should be certain, which also conforms to Raspberry's theory . The absorbance value of the hemp cotton fiber solution should also conform to Rasbury's formula.

[0027] A kind of test method of hemp / cotton blend ratio, concrete test steps are as follows:

[0028] (1) Select the hemp and cotton varieties of the hemp / cotton mixture that need to measure the blending ratio, test the absorbance value Aa of the cotton fiber solution, the absorbance value Ab of the hemp fiber solution, and the known mixing ratio of the hemp / cotton mixture that is Fa. The absorbance value A of the liquid, the absorbance value Aa, Ab of cotton and hemp and the absorbance value A of the hemp / cotton mixture with known mixing ratio are brought int...

Abstract

The invention discloses a flax-to-cotton blending ratio detecting method, which is characterized by the following: selecting the detected blending ration flax and cotton specimen; detecting the absorption value Aa of cotton solution, Ab of flax solution and A of known blending ratio solution; putting these absorption values in the Lazuli formula to count the ª‡ value of flax-to-cotton mixture; putting the sample mixture in the sulfuric solution; filtering and cooling the solution and to detect the absorption value A; calculating the blending ratio Fa of cotton fiber through Lazuli formula.

Description

technical field [0001] The invention relates to the technical field of textile testing, in particular to a testing method for the hemp / cotton blending ratio. Background technique [0002] Because both hemp and cotton belong to natural cellulose fibers, their chemical properties are relatively close, so the traditional dissolution method and specific gravity method cannot be used. The most widely used test method is the microscope method. That is, the fibers are cut into flakes, the number of hemp fibers is counted under a microscope, and the blending ratio is calculated according to the diameter and specific gravity of the two fibers. This method has been included in the industry standard, which solves the problem of quantitative analysis of hemp and cotton content in the current work, but there are still the following deficiencies: [0003] (1) The workload is heavy. It is necessary to measure hundreds or even thousands of fibers, which will cause eye fatigue and errors....
