SN/T 1901-2014Import and export textile. Test method for identification of fibre. Polyester fibres (polylactic acid fibre, polytrimethy-leneterephthalate fiber, polybutyleneterephthalate fibre) (English PDF)

Foreword

This standard was drafted in accordance with GB/T 1.1-2009 given rules.

Instead of the standard SN/T 1901-2007 "series identification method seven kinds of textile fibers." this standard compared with SN/T 1901-2007, the main differences are as follows.

--- Change the standard name is. import and export of textile fiber identification method of polyester fiber (polylactic acid, poly propylene Ester, polyethylene terephthalate, polybutylene terephthalate).

--- Modify the "1" and press FZ/T 01053.1-2009 preface, relating to the modification of the standard provides six qualitative identification method Title, adding "Raman spectroscopy", the scope of the standard changed to "This standard applies to polyester fiber (polylactic acid, polyethylene terephthalate Dicarboxylic acid, propylene glycol, polyethylene terephthalate, polybutylene terephthalate) qualitative identification. "

--- "3 Terms and definitions" will be changed to 3.1 polylactic acid fiber, 3.2 to polyethylene terephthalate fiber, 3.3 to Polyethylene terephthalate, polybutylene terephthalate fiber, 3.4 deleted.

--- In the "7 test", press FZ/T 01053.1-2009 preface, six kinds of modifications of the standard qualitative identification method involves providing said that; in the "7.7 Infrared Spectroscopy" principle 7.7.1 to increase "7.7.1.1 infrared absorption spectroscopy principle" "7.7.1.2 attenuated total reflection (ATR) principle" and "7.7.4.2 attenuated total reflection (ATR) method (reflection method)"; add "7.8 Raman Spectroscopy Method. "

--- Amend Appendix A, Appendix B, Appendix C, Appendix D, Appendix E, Appendix F, Appendix G, Appendix H, Appendix I content. Increase polyparaphenylene Polybutylene terephthalate acid content; deleted soybean protein/PVA composite fiber, milk protein/polyacrylonitrile composite fiber Victoria, lyocell, bamboo fiber and chitin content; Appendix I will be replaced by "Annex I (normative) polylactic acid, polyethylene terephthalate Formic acid, propylene glycol, polyethylene terephthalate, polybutylene terephthalate fiber Raman shift peaks "; add" Appendix J (normative) polylactic Acid, polyethylene terephthalate, polyethylene terephthalate, polybutylene terephthalate fiber standard Raman spectrum, "and the original Annex I (capital Material appendix) to Annex K (informative) "The main polyester fiber specific identification method." this standard is proposed and managed by the National Certification and Accreditation Administration Committee.

This standard was drafted. People's Republic of China Zhejiang Exit Inspection and Quarantine.

Drafters of this standard. Wu Jian Jian, Zhao Hong Shan, Xie Weibin, Chen Qi Group, Sun Guojun.

This standard replaces the standards previously issued as follows.

--- SN/T 1901-2007.

Import and export of textile fiber identification method Polyester fiber (polylactic acid, polyethylene terephthalate Propylene glycol, polyethylene terephthalate, polybutylene terephthalate)

1 Scope

This standard provides for the polyester fibers eight qualitative identification methods. combustion, microscopy, dissolution method, coloring, chlorine-containing nitrogen was Color reaction, melting point, infrared spectroscopy, Raman spectroscopy.

This standard applies to polylactic acid, polyethylene terephthalate, poly (butylene terephthalate) qualitative identification of.
