Qualitative analysis of textile fiber for import and export Bamboo fibrils1 ScopeThis 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.2 Normative referencesThe following documents are indispensable for the application of this document. For dated references, only dated versions apply to this article. Pieces. For undated references, the latest edition (including all amendments) applies to this document.

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. ...... |
