SN/T 3780-2014 Textile for import and export - Method for identification of fiber - Banana, pineapple, lotus, coconut and mulberry fiber 1 Scope This standard specifies the qualitative identification of five types of plant fibers using methods such as microscopic observation, fiber fineness testing, density testing, fiber rotation testing, coloring test, and thermal decomposition testing. This standard is applicable to the qualitative identification of raw materials of banana fiber, pineapple fiber, lotus fiber, coconut fiber, and mulberry fiber. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. GB/T 2910.1-2009 Textiles - Quantitative chemical analysis - Part 1: General principles of testing GB/T 5889-1986 Method of quantitative analysis of ramle chemical components GB/T 11951-1989 Textiles - Natural fibres - Generic names and definitions FZ/T 01057.7-2007 Test method for identification of textile fibers - Part 7: Density gradient column method 3 Terms and definitions For the purposes of this document, the terms and definitions given in GB/T 11951 and the following apply. 3.1 banana fiber fiber extracted from banana stalks 3.2 pineapple fiber fiber extracted from pineapple leaves 3.3 lotus fiber fiber extracted from lotus stalks 3.4 coconut fiber fiber obtained from the outer shell of coconuts 3.5 mulberry fiber bast-type fiber obtained from the bark of mulberry trees 3.6 main decomposition temperature temperature corresponding to the peak point on the derivative thermogravimetric (DTG) curve 4 Principle Based on the distinct physical and chemical properties of the five types of plant fibers, different analytical methods are adopted to test the samples. The test results are then compared with relevant technical characteristics to identify the five types of plant fibers. 5 Sample pretreatment
