Batch fiber dissolving method

Abstract

The invention discloses a batch fiber dissolving method which comprises the following steps: filling small samples into corrosion-resistant filter bags, putting the filter bags into a sample tank in batches, and automatically carrying out liquid adding, liquid discharging, dissolving, neutralizing, washing, dewatering and other procedures by a system, thereby completing the dissolution of selectedcomponents in the small samples and the washing and dewatering drying of small sample residues. According to the invention, a plurality of filter bags filled with small samples are put into the sample tank, and the procedures of dissolving, neutralizing and washing are carried out in batches, so that the detection efficiency is improved, the labor investment is reduced, the working intensity of operators is reduced, and the stability of the detection process is ensured. Meanwhile, the processes of liquid adding, liquid discharging, dissolving and the like are all automatically operated by thesystem, an operator does not need to make contact with solutions such as a dissolving reagent, the safety of the operator is guaranteed, the safety of the detection process is improved, and the requirement for large-batch detection is met.

Description

technical field [0001] The invention relates to the technical field of detection equipment, in particular to a method for dissolving fibers in batches. Background technique [0002] The composition and content of textile fibers are important indicators related to the performance, cost and product care of textiles, clothing and home textile products. At present, many countries have incorporated the labeling of fiber content into mandatory standards, and it has become one of the contents that must be disclosed to consumers for all clothing and home textiles to be sold. The authenticity of the content of fiber composition and content is also one of the items of various market supervision and inspection, and it is also an item with a high incidence of unqualified items in the supervision and random inspection of various textiles. [0003] The premise of accurate identification of fiber composition and content is the precise determination of fiber composition and content. For th...

Problems solved by technology

[0004] However, the existing chemical dissolution quantitative analysis method requires manual participation in the whole process of operation, and because the dissolution efficiency is low, manual continuous stirring or shaking of the Erlenmeyer flask containing reagents and small samples is required.

Since the reagent solution used in this method is basically a strong acid or strong alkali, if the operator makes a slight mistake, it may cause personal injury

Moreover, each batch of textiles needs to be tested many times, and the workload is heavy, which may easily lead to operator fatigue, which is not conducive to safety and accuracy of test results.
