Textiles — Binary fibre mixtures — Quantitative chemical analysis
The parent entry for binary fibre analysis: two fibres, one dissolved, the other weighed. Every numbered part below is one pair and one reagent, and this record is…

International Organization for Standardization
The international consensus standard, and usually the one a crosswalk is filed under. Textile test methods sit in technical committee TC 38.

What are ISO, ASTM and AATCC — and what do IDT, MOD and NEQ mean?
Calculators on this site cite 35 further standards that the register does not cover yet. They are being written in order of how many tools need them.
ISO 1833-1
Textiles — Quantitative chemical analysis — Part 1: General principles of testing
How the percentages on a composition label are established — dissolving one fibre away and weighing what is left.
ISO 1833-10
Textiles — Quantitative chemical analysis — Part 10: Mixtures of triacetate or polylactide with certain other fibres (method using dichloromethane)
Triacetate or polylactide dissolved in dichloromethane. The polylactide case matters more each year as PLA appears in compostable and bio-based textiles, and it is easy to misread as…
ISO 1833-11
Textiles — Quantitative chemical analysis — Part 11: Mixtures of certain cellulose fibres with certain other fibres (method using sulfuric acid)
Cellulose fibres dissolved in sulfuric acid, leaving polyester, polypropylene and other acid-resistant synthetics. The standard method for proving the synthetic content of a cotton-polyester blend, which is most…
ISO 1833-12
Textiles — Quantitative chemical analysis — Part 12: Mixtures of acrylic, certain modacrylics, certain chlorofibres, certain elastane fibres with certain other fibres (method using dimethylformamide)
Acrylic, some modacrylics, some chlorofibres and some elastanes dissolved in dimethylformamide. The part that covers the widest set of fibres, and correspondingly the one where identifying the fibre…
ISO 1833-13
Textiles — Quantitative chemical analysis — Part 13: Mixtures of certain chlorofibres with certain other fibres (method using carbon disulfide/acetone)
Chlorofibres dissolved in carbon disulfide with acetone. The reagent is flammable and acutely toxic, and this method should not be attempted outside a fume cupboard by anyone who…
ISO 1833-14
Textiles — Quantitative chemical analysis — Part 14: Mixtures of acetate with certain other fibres (method using glacial acetic acid)
Acetate dissolved in glacial acetic acid. The third acetate route in the series, after acetone and benzyl alcohol - the series offers several because the right one depends…
ISO 1833-15
Textiles — Quantitative chemical analysis — Part 15: Mixtures of jute with certain animal fibres (method by determining nitrogen content)
Jute separated from animal fibres by measuring nitrogen rather than by dissolution. The odd method in the series: protein contains nitrogen and jute contains almost none, so the…
ISO 1833-16
Textiles — Quantitative chemical analysis — Part 16: Mixtures of polypropylene fibres with certain other fibres (method using xylene)
Polypropylene dissolved in hot xylene, leaving almost everything else. Polypropylene resists nearly every reagent in the series, which is why it needs a boiling hydrocarbon to shift it.…
ISO 1833-17
Textiles — Quantitative chemical analysis — Part 17: Mixtures of cellulose fibres and certain fibres with chlorofibres and certain other fibres (method using concentrated sulfuric acid)
Cellulose fibres dissolved in concentrated sulfuric acid, leaving chlorofibres and other resistant synthetics. The stronger companion to Part 11, for blends where the residue would survive the milder…
