ISO 1833-24:2010 specifies a method using phenol and tetrachloroethane to determine the percentage of polyester after removal of non-fibrous matter, in textiles made of binary mixtures of certain polyester fibres with acrylic, polypropylene or aramid fibres. This method is not applicable to coated fabrics.

Overview

ISO 1833-24:2010 - Textiles - Quantitative chemical analysis - Part 24 specifies a laboratory method to determine the percentage of polyester in binary textile blends containing polyester with acrylic, polypropylene or aramid fibres. The method uses a solvent mixture of phenol and tetrachloroethane to dissolve polyester from a known anhydrous sample mass; the remaining residue is washed, dried and weighed to calculate polyester content by difference. The procedure is not applicable to coated fabrics.

Key topics and technical requirements

Scope: Quantitative chemical analysis of polyester in binary mixtures (polyester + acrylic/PP/aramid), after removal of non‑fibrous matter.

Solvent system: Phenol/tetrachloroethane mixed at a mass ratio of 6:4.

Reagents: Phenol/tetrachloroethane mixture and ethanol (plus reagents referenced in ISO 1833-1:2006).

Apparatus: Minimum 250 ml conical (ground‑stopper) flask, heating device to maintain (50 ± 2) °C (e.g., thermostatted water bath), tared filtering crucible, drying and balance for weighing.

Procedure highlights:

Add 100 ml of solvent per gram of sample, agitate 10 minutes at 50 ±2 °C.
Decant/filter, repeat with a further 100 ml of solvent preheated to 50 ±2 °C.
Wash residue twice with 100 ml ethanol, rinse with water, dry and weigh.
Calculate results per ISO 1833-1:2006 (the density correction value d = 1.00).

Safety: Phenol and tetrachloroethane are hazardous - work under a fume hood and follow appropriate health, safety and environmental controls.

Applications and users

Quality control in textile manufacturing to verify declared fabric composition.

Independent textile testing labs performing composition analysis for compliance, labelling and dispute resolution.

Recycling and material sorting where accurate quantification of polyester aids downstream processing.

Research and development groups studying blend behavior or developing separation methods.

Typical users: textile laboratories, contract testing organizations, manufacturers, recyclers and material scientists.
