Another International Standard Issued By China Textile Institute

Recently, the international standard ISO 5079:2020 "determination of breaking strength and elongation at break of single fiber of textile fiber" drafted by China National Textile Standards Inspection and Certification Co., Ltd. (hereinafter referred to as "China Textile Standard") was officially released. This standard is a comprehensive revision of ISO 5079:1995.

With the vigorous development of the world textile fiber industry, aramid fiber, polyimide fiber, polyphenylene sulfide fiber, polylactic acid fiber, ultra-high molecular weight polyethylene fiber and other new fibers have been widely used in various fields The standard "determination of breaking strength and elongation at break of single fiber" lacks test parameters for these new fibers, which affects the accuracy of test results, and can not meet the requirements of product technical testing, which is not conducive to the further development and application of new fiber products. Therefore, China takes the lead in proposing a comprehensive revision of ISO 5079:1995.

This paper provides a new method for testing the tensile properties of monofilament in the world.

At present, the global market scale of new textile fiber products exceeds 100 billion US dollars, which has become one of the new "strategic pillar industries" of the textile industry. The release of ISO 5079:2020 has enhanced the discourse power and influence of international standards in the field of new textile fiber technology in China. It is of great significance to standardize the testing standards in this field, accelerate the industrialization process of new textile fibers in the global market, meet the development needs of high-tech fields, and improve the core competitiveness of China's textile industry.

As the domestic technical counterpart of ISO / tc38, China National Textile Standards Co., Ltd. has undertaken the ISO / tc38 chairman unit, ISO / tc38 / SC2 and sc23 International Secretariat. It has been actively participating in the international standardization work. In the future, it will promote the new development of international standardization with more open and rigorous attitude, increase the research and development of international standards in the field of textile characteristics, and give full play to it The role of high quality standards in promoting high-quality development.
