This document is Part 16 of GB/T 2910 Textiles - Quantitative chemical analysis. The following parts have been issued for GB/T 2910. -- Part 1.General principles of testing; -- Part 2.Ternary fibre mixture; -- Part 3.Mixtures of acetate and certain other fibres (method using acetone); -- Part 4.Mixtures of certain protein fibres with certain other fibres (method using hypochlorite); -- Part 5.Mixtures of viscose, cupro or modal and cotton fibres (method using sodium zincate); -- Part 6.Mixtures of viscose or certain types of cupro or modal or lyocell and cotton fibres (method using formic acid and zinc chloride); -- Part 7.Mixtures of polyamide and certain other fibres (method using formic acid); -- Part 8.Mixtures of acetate and triacetate fibres (method using acetone); -- Part 9.Mixtures of acetate with certain other fibres (method using benzyl alcohol); -- Part 10.Mixtures of triacetate or polylactide and certain other fibres (method using dichloromethane); -- Part 11.Mixtures of certain cellulose fibres with certain other fibres (method using sulfuric acid); -- Part 12.Mixtures of acrylic, certain modacrylics, certain chlorofibres, certain elastane fibres with certain other fibres (method using dimethylformamide); -- Part 13.Mixtures of certain chlorofibers and certain other fibers (method using carbon disulfide/acetone); -- Part 14.Mixtures of acetate and certain chlorofibres (method using acetic acid); -- Part 15.Mixtures of jute and certain animal fibres (method by determining nitrogen content); -- Part 16.Mixtures of polypropylene and certain other fibres (method using xylene); -- Part 17.Mixtures of chlorofibers (homopolymers of vinyl chloride) and certain other fibers (method using sulfuric acid); -- Part 18.Mixtures of silk and wool or hair (method using sulfuric acid); -- Part 19.Mixtures of cellulose fibres and asbestos (method by heating); -- Part 20.Mixtures of elastane and some other fibers (method of using dimethylacetamide); -- Part 21.Mixtures of chlorofibers, certain modacrylics, certain elastanes, acetates, triacetates and certain other fibers (method using cyclohexanone); -- Part 22.Mixtures of viscose or certain types of cupro or modal or lyocell and flax of ramie fibres (method using formic acid and zinc chloride); -- Part 23.Mixtures of polyethylene and polypropylene (method using cyclohexanone; -- Part 24.Mixtures of polyester and some other fibers (method using phenol and tetrachloroethane); -- Part 25.Mixtures of polyester and certain other fibres (method using trichloroacetic acid and chloroform); -- Part 26.Mixtures of melamine and cotton or aramide fibers (method using hot formic acid); -- Part 101.Mixtures of soybean protein composite fibre and certain other fibers. This document serves as a replacement of GB/T 2910.16-2009 Textiles - Quantitative chemical analysis - Part 16.Mixtures of polypropylene and certain other fibres (method using xylene). In comparison with GB/T 2910.16-2009, apart from structural adjustments and editorial modifications, the main technical changes are as follows. -- Change the Scope by including lyocell fiber, polyester composite elastic fiber, melamine fiber and polyacrylate fiber (see Chapter 1; Chapter 1 of the 2009 edition); -- Change the boiling point of xylene from “137 ℃ ~ 142 ℃” to “136 ℃ ~ 145 ℃” (see Chapter 5; Chapter 4 of the 2009 edition); -- Change “stoppered conical flask” to “stoppered round-bottom flask” (see Chapter 6; Chapter 5 of the 2009 edition); -- Add 6.3 Heating mantle apparatus (see 6.3); -- Improve the Test procedures, by specifying the preheating temperature, and supplementing the alternative test apparatus (see Chapter 7; Chapter 6 of the 2009 edition); -- Add the d value of the newly added fibers (see Chapter 8); -- Change the confidence limit in Precision from “not more than ±1” to “not more than ±1%” (see Chapter 9; Chapter 8 of the 2009 edition). This document modifies and adopts ISO 1833-16.2019 Textiles - Quantitative chemical analysis - Part 16.Mixtures of polypropylene fibres with certain other fibres (method using xylene). The technical differences between this document and ISO 1833-16.2019, and the causes for these differences are as follows. -- Use the normative reference GB/T 2910.1 to replace ISO 1833-1 (see Chapters 5 ~ 8), for standard use.

The previous versions of this document and the documents which are replaced by this document are as follows. -- First published in 1982 as GB 2910-1982, and first revised in 1997 as GB/T 2910-1997; -- Second revised in 2009 as GB/T 2910.16-2009; -- This is the third revision.1 ScopeThis document describes a method for the determination of the polypropylene fiber content in a two-component mixture consisting of the following fibers after removal of non-fibrous matter using the xylene method.2 Normative referencesThe following documents are referred to in the text in such a way that some or all of their content constitutes requirements of this document. For dated references, only the version corresponding to that date is applicable to this document; for undated references, the latest version (including all amendments) is applicable to this document.3 Terms and definitionsNo terms and definitions need to be defined in this document.4 PrincipleUse boiling xylene to dissolve and remove the polypropylene fiber from a mixture of known dry mass; collect the residue; wash, dry and weigh it; use the corrected mass to calculate its percentage of the dry mass of the mixture.5 ReagentsUse the reagents specified in GB/T 2910.1 and 5.1. Warning. This reagent is harmful to the human body.6 ApparatusUse the apparatus specified in GB/T 2910.1 as well as 6.1, 6.2 and 6.3.7 Test proceduresFollow the general procedures specified in GB/T 2910.1, and then follow the steps below.8 Calculation and presentation of resultsThe calculation and presentation of the results shall be in accordance with the provisions of GB/T 2910.1.9 PrecisionFor a homogeneous mixture of textile materials, at the 95% confidence level, the confidence limit of the test results of this method shall not exceed ± 1%. ......Source: Above contents are excerpted from the full-copy PDF -- translated/reviewed by: www.ChineseStandard.net / Wayne Zheng et al. |
