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 Βͺ‑ 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....
