Foreword

This standard was drafted in accordance with the rules given in GB/T 1.1-2009. This standard is proposed and managed by the National Certification and Accreditation Administration. This standard was drafted. Shanghai Entry-Exit Inspection and Quarantine Bureau of the People's Republic of China, Suzhou Shengzhu Household Textile Co., Ltd., China Shenzhen Entry-Exit Inspection and Quarantine Bureau of the People's Republic of China, Jiangsu Entry-Exit Inspection and Quarantine Bureau of the People's Republic of China, and the People's Republic of China Inspection and Quarantine Bureau, Xinjiang Entry-Exit Inspection and Quarantine Bureau of the People's Republic of China, Liaoning Entry-Exit Inspection and Quarantine Bureau of the People's Republic of China, Donghua Key Laboratory of the Ministry of Ecology Textiles of the Ministry of Education. The main drafters of this standard. Li Hongtao, Yan Naiqing, Zhao Yuwei, Wang Weihua, Chen Baoxi, Wang Xiaoping, Yan Huaiyu, Ma Weiming, Mao Zhiping. Qualitative analysis of textile fiber for import and export Bamboo fibrils

1 Scope

This standard specifies the combustion test method, microscopic observation method, viscosity method (polymerization method), wide-angle X-ray diffraction method, fiber rotation direction Five kinds of test methods for qualitative identification of bamboo fibrils. This standard applies to the qualitative identification of bamboo fibrils using a combination of these methods and methods.

3 Terms and definitions

The following terms and definitions as defined in GB/T 3291.1 and GB/T 5707 apply to this document. 3.1 Bamboo fiber naturalbamboofiber A cellulose fiber directly extracted from naturally grown bamboo by a combination of physical and chemical methods. 3.2 Cellulose crystallinity crystalinityofcelulose The proportion of the crystalline regions in the cellulose and the crystalline regions in the amorphous regions. 3.3 Degree of polymerization The number of repeating structural units on the macromolecular chain of the polymer.

4 Principle

According to the growth law of bamboo fibrils and the unique physical and chemical properties, compared with other cellulose fibers in fiber size, morphological characteristics, and aggregation The combination of the degree of synthesis and the crystal structure, the combustion test method, the microscope observation method, the viscosity method (polymerization degree method), the wide-angle X-ray diffraction method, Five test methods and combinations of fiber rotation direction method are used to qualitatively identify bamboo fibrils. Note. Since bamboo fibrils have the chemical properties of cellulose fibers, some of them have been proved by the relevant literature, and have little significance for the identification of bamboo fibrils. Classical chemical methods and modern instrumental analysis methods are not quoted in this standard.
