specific Embodiment approach 1

[0039] Specific implementation mode one: a kind of textile component analysis method of this implementation mode, carry out according to the following steps:

[0040] 1. Cut the mixed fiber bundles into mixed short fibers with a length of 1mm-20mm, uniformly disperse the mixed short fibers, then perform electrostatic induction treatment, and then pass electrostatic regular sorting treatment, fix the mixed short fibers evenly and vertically on the bottom of the container, and arrange them The density is 100-1500 pieces / mm 2 ;

[0041] 2. Pour the embedding reaction solution into the container, and then irradiate it with LED cold light source ultraviolet light. The irradiation time is 5-30 minutes to obtain the embedded mixed short fiber; the adding speed of the embedding reaction solution is 2- 6ml / min, the intensity of ultraviolet light from the LED cold light source is 3000-80000uW / cm at the center of 38cm 2 ;

[0042] 3. Slice the embedded mixed short fibers with a thickn...

specific Embodiment approach 2

[0065] Embodiment 2: This embodiment is different from Embodiment 1 in that: the mixed fiber bundle is cut into short mixed fibers with a length of 5mm-10mm. Others are the same as Embodiment 1.

specific Embodiment approach 3

[0066] Specific embodiment three: the difference between this embodiment and specific embodiment one or two is that in step one, uniformly disperse and mix short fibers, as electrostatic induction refers to uniformly disperse and mix short fibers in a dispersant aqueous solution, and then add an electrostatic inducer Induction for 5-20 minutes, wherein the mass concentration of the dispersant aqueous solution is 3%, the dispersant is IW, and the electrostatic inducer is a mixture of antistatic agent SN, aluminum potassium sulfate, sodium silicate and glacial acetic acid: the electrostatic inducer in the dispersant aqueous solution The mass final concentration is: antistatic agent SN 5%, aluminum potassium sulfate 5%, sodium silicate 1%, glacial acetic acid 1%. Others are the same as those in Embodiment 1 or 2.

Abstract

The invention relates to a method for analyzing textile components. The invention aims to solve the problem of measurement of the blending ratio of blended products, the problem of pollution caused byusing a lot of organic solvents and acid and alkali reagents in measurement of the blending ratio as well as the problems of digitalization and intelligentization in check of textile components. Themethod comprises the following steps: cutting mixed fiber bundles into mixed short fibers; performing uniform dispersion, and then, performing electrostatic induction treatment; performing electrostatic regular sorting treatment to uniformly and vertically fix the mixed short fibers at the bottom of a container; slowly pouring embedding reaction liquid into the container, and performing ultraviolet irradiation to induce cross-linking solidification of the embedding reaction liquid; and cutting slices, transferring the cut slices onto a microscope sample stage, taking pictures for recording initial cross-section views of a plurality of positions, treating the samples, taking pictures for recording images after the samples are treated, identifying the varieties of fibers through an image identification technology, and calculating the weight percentage. The method provided by the invention solves the problem of pollution to the environment by solvents, and the deviation is only 3%. The method provided by the invention is applied to the field of quantitative analysis of textiles.

Description

technical field [0001] The invention belongs to the field of quantitative analysis of textiles, and in particular relates to a composition analysis method of textiles. Background technique [0002] Textile inspection items are mainly divided into physical inspection and chemical inspection. The digitalization and automation of physical performance index inspection are relatively easy to realize; chemical inspection items include ecological safety indicators such as heavy metals, formaldehyde, pesticide residues, carcinogenic and allergenic dyes, and textile composition inspection. Big item, the current textile composition inspection has not been able to achieve digitalization and intelligence. The key technical difficulty lies in the complexity and variety of fiber types, and it is difficult to extract enough characteristic physical and chemical information of each fiber at the same time, resulting in the inability to perform accurate and reliable qualitative and quantitative...
