Foreword
This document was drafted in accordance with the rules given in GB/T 1.1-2020,
Directives for standardization - Part 1.Rules for the structure and drafting of
standardizing documents.
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);
Textiles - Quantitative chemical analysis - Part 16.Mixtures
of polypropylene fibres with certain other fibres (method
using xylene)
1 Scope
This 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.
-- polypropylene fibres, and
-- sheep wool, other animal hair fibers, silk, cotton, viscose fibers, cupro fiber,
modal fiber, lyocell fiber, acetate fiber, triacetate fiber, polyamide fiber,
polyester fiber, polyacrylonitrile fiber, glass fiber, polyester composite elastic
fiber, melamine fiber and polyacrylate fiber.

The 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.

principles of testing (GB/T 2910.1-2009, ISO 1833-1.2006, IDT)
3 Terms and definitions
No terms and definitions need to be defined in this document.
4 Principle
Use 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. Obtain the mass fraction of the
polypropylene fiber from the difference.
