Problems solved by technology

This method is time-consuming and has large errors
The dyeing method is based on the principle of dye balance (the amount of adsorption on the fiber is equal to the reduction of dye in the dyeing bath), dyeing a group of linen-cotton blends with a known content of linen-cotton blending, as a standard, using a spectrophotometer Measure the concentration of residual dye solution, calculate the standard curve by linear regression method, and then use the same dyeing process to measure the concentration of residual dye solution to obtain the component content of the sample to be tested. However, the time required for dyeing equilibrium is at least 4 to 5 hours, which takes a long time and the error Generally 5%~8%

Abstract

The invention relates to a three-primary colours dye and a method for detecting two fibers blending ratio of linen to cotton, and relates to the method for detecting ratio of cotton fiber to linen fiber in a linen-cotton blending fabric, the method comprises the following steps: adding water in a mixture of direct date red GB to cationic bright yellow to disperse blue 2BLN of 1:1:1 according to weight ratio to prepare a three primary colors dye liquid, diluting the three primary colors dye liquid, immersing the linen-cotton fiber blending substrate to be measured and dyeing, using a reflective spectrophotometer to determine the tristimulus values of X, Y and Z of the dried dyed linen-cotton fiber blending substrate; and substituting the tristimulus values in a cotton fiber content linear regression equation to calculate the ratio of the cotton fiber to two fibers of linen and cotton. The three primary colors dye is the dye with high detection precision used for detecting by a dying method. The detection method is simple, the error for detecting two fibers blending ratio of linen to cotton is less than 3%, the speed is rapid, and the detection efficiency is high, and the examination work strength can be greatly reduced.

Description

technical field [0001] The invention relates to a method for identifying the amount of fibers, in particular to a method for detecting the ratio of cotton fibers and hemp fibers in cotton and linen blended fabrics. Background technique [0002] The analysis of fiber blend components usually adopts chemical dissolution analysis method, and there are chemical analysis methods of various fibers in national standards or textile professional standards. This method is based on the difference in chemical properties between the different fiber components in the yarn. The instrument required for this method is simple and the result is reliable. This method only detects a certain kind of hemp fiber or cotton fiber. [0003] But above-mentioned this detection method can not distinguish the hemp fiber or the cotton fiber of the hemp-cotton blended fabric and measure the cotton fiber and the hemp fiber ratio. This is because hemp and cotton belong to cellulose fibers and have similar...
