Problems solved by technology

However, since cotton and hemp fibers belong to cellulose fibers, they have the same characteristic band in the mid-infrared region, and cannot be simply distinguished by characteristic wavelengths.

Embodiment Construction

[0020] Embodiments of the present invention will now be described with reference to the drawings, in which like reference numerals represent like elements.

[0021] like figure 1 , the method for quickly identifying cotton and linen fiber in the present embodiment comprises the steps:

[0022] Step S1, take a total of 50 cotton and hemp samples, including samples of different colors and different fabric structures, and the analysis samples include cotton and pure hemp samples of different colors and different fabric structures, wherein pure hemp includes ramie and flax, which are used for cotton , Establishment of hemp fiber identification model;

[0023] Step S2, using the X-ray diffraction method to measure the degree of orientation of the cotton sample and the degree of orientation of the whole hemp sample. The measurement results show that the degree of orientation of the pure hemp sample is 75.0%-95.0%, and the degree of orientation of the whole cotton sample is 60.0%. ...

Abstract

The invention discloses a method for quickly identifying cotton and hemp fibers, which comprises the following steps: (1) establishing an equation between the orientation degree of a sample of whole cotton and hemp and the spectral value corresponding to the characteristic wavelength of the whole cotton and hemp; (2) Collect the reflection mid-infrared spectrum of the sample to be tested, find out the spectral value of the sample to be tested corresponding to the characteristic wavelength of cotton and hemp in the reflection mid-infrared spectrum of the sample to be tested, and substitute the spectral value of the sample to be tested into the cotton, (3) compare the orientation degree of the sample to be tested with the value range of the orientation degree of the whole cotton and hemp samples, thereby determining whether the sample to be tested is cotton fiber or Whole hemp fiber. The method of the invention is not only simple to operate, but also can improve detection efficiency, reduce the work intensity and requirements of detection personnel, ensure the integrity of detection samples, and meet the needs of rapid detection in large quantities.

Description

technical field [0001] The invention belongs to the field of textile component identification, in particular to a method for quickly identifying cotton and hemp fibers. Background technique [0002] In order to protect the legitimate rights and interests of consumers, almost all countries in the world have promulgated decrees or standards stipulating that textiles sold in the market must have labels indicating the composition of textile raw materials. However, in order to reduce costs, some fabric manufacturers have arbitrarily reduced the content of certain fiber components in blended fabrics, cut corners, shoddy, and defrauded consumers. China is the largest producer, exporter and consumer of textiles in the world. All kinds of cotton and linen textile products are welcomed by consumers because of their unique style and comfortable wearing. In order to maintain market order, protect consumer rights, and encourage fair competition, it is very important to quickly and accur...
