Qualitative And Quantitative Analysis Of Pure Bamboo Pulp Fiber

A few days ago, the qualitative and quantitative detection of bamboo fiber was studied by the Ningbo inspection and Quarantine Bureau's textile inspection center, which was held by the science and Technology Department of the General Administration of quality supervision, inspection and quarantine, and was appraised by the appraisal expert group.

The project has successfully completed the predetermined target and solved the problem of qualitative determination of pure bamboo fiber products and quantitative detection of conventional bamboo fiber blended products.

Most of the traditional cellulose fibers are made from pulp made from cotton and wood pulp. Today, with the depletion of the earth's resources, "low carbon" has become a mainstream concept, and bamboo fiber products have come into being.

With the increasingly extensive application of bamboo pulp fiber, the qualitative and quantitative analysis method of distinguishing bamboo from other fibers has become a hot research topic at present.

The summary report is just a thin pamphlet, but it embodies the wisdom and sweat of every member of the research group.

In addition to observing fibrous tissue, the chemical properties of bamboo pulp fiber, such as solubility and combustion properties, should be identified.

In order to ensure the effectiveness of the experiment, researchers often neglect the normal commuting time.

After mastering the basic physical and chemical properties of bamboo pulp, it is necessary to further analyze the dissolution properties of bamboo pulp fiber and other fiber chemical reagents, in order to determine the different quantitative analysis methods of bamboo pulp fiber and other fibers.

In the process of selecting the reagent, two times a time, three times, four times, many times failed, try more times! After countless hours of overtime work, finally selected the appropriate reagent.

Faced with such a thorny problem of separating bamboo fiber from other fibers, the whole team has no one to shrink from.

Whether it is a member of the research group or a general inspector of the laboratory, we have worked together and worked out a lot of experiments, analyses and summaries. Finally, we have got the way of quantitative analysis. The successful practice of this method provides a key technical support for the next step in formulating the relevant standards of bamboo fiber.

In this way, the Ningbo textile inspection center of the inspection and Quarantine Bureau has successfully completed this research project. The subject was verified by the Shanghai inspection and Quarantine Bureau, the Shenzhen inspection and Quarantine Bureau, the Fujian inspection and Quarantine Bureau, the national wool textile product quality supervision and Inspection Center (Shanghai), the Guangzhou Textile Industry Research Institute Lining (China) Sporting Goods Co., Ltd., the inspection and quarantine system laboratory and the textile inspection institution laboratory. The results of the structural test are quite accurate with the error within 1%, which proves that it can be applied in practice.

The textile inspection center of Ningbo inspection and Quarantine Bureau was founded in 1984. It is the National Key Laboratory of textile and clothing inspection. It is also the earliest textile inspection laboratory approved by China National Accreditation Committee for conformity assessment (CNAS) and China Metrology Accreditation (CMA). The accreditation domain covers textiles, clothing, fur and leather, children's clothing, textile raw materials and other products. Currently, it can undertake more than 300 items of textile and textile safety, health and other testing items.

The laboratory has strong testing technology strength, with nearly 100 technical personnel, including 1 post doctoral students, 5 senior engineers, and 10 graduate students. All of them are professional and technical personnel who are related to textile testing and have many years of practical work experience.

Over the years, this gathering of more than one professional team of people is down-to-earth, in the laboratory, with their sweat writing one after another development of the main chapter of the laboratory.

Significance

First of all, it helps to break the technical trade measures set up by European and American countries to China's textile exports.

At present, there is no corresponding standard for the detection of bamboo fiber in our country. Only the relevant physical and chemical methods can be used to identify the viscose fiber, and the bamboo viscose fiber can not be accurately identified. This detection bottleneck will be broken after the success of the research.

For entry exit inspection institutions, it is very important to shorten the detection time and improve the detection efficiency under the premise of ensuring the accuracy of the experimental results. This will help to greatly improve the clearance speed, shorten the detection time of foreign trade textiles in the testing institutions, and help to shorten the detection speed of the textiles in the customs and other departments, so that the testing time can be shortened from 1 days to 2 days to the current 2~3 hours, so as to achieve the desired service efficiency.

This breakthrough is a revolution for domestic bamboo fiber detection. It will lead the bamboo fiber industry to enter the standardized debugging period ahead of time, and guide the industry to change from disorder to non standard state to an orderly and standard state.

At the same time, it also broke through the traditional application fields of bamboo, enriched the connotation of bamboo culture, and accorded with the trend of development of the times.
