Full title and description

Textiles — Cotton fibres — Evaluation of maturity by the air flow method. ISO 10306:2014 specifies a laboratory method to evaluate the maturity of loose, randomized cotton fibres by measuring the resistance to air flow of a plug of cotton fibres under two prescribed conditions; the method is intended primarily for cotton taken at random from bales.

Abstract

ISO 10306:2014 defines an air‑flow based test procedure for indirect assessment of cotton fibre maturity. The standard describes sample preparation (loose, randomized fibres), an air‑permeability measurement of a fibre plug under two specified compressions/conditions and interpretation of the measured resistance to air flow as an indicator of fibre maturity; laps, slivers or other lint sources may be tested but results can differ from bale samples.

Scope

This standard specifies a reproducible test method for evaluating cotton fibre maturity by measuring air flow resistance of a plug of loose fibres under two prescribed conditions. It is applicable to cotton sampled at random from bales; alternative sources of lint (laps, slivers) can be tested but may yield differing results. The procedure is intended for quality control, research and inter‑laboratory comparison where maturity is a relevant property.

Key topics and requirements

• Definition of sample type and preparation: loose, randomized cotton fibres (bale samples are the primary sample source).
• Measurement principle: determination of resistance to air flow of a fibre plug measured under two specified conditions/compressions.
• Instrumentation and test setup: controlled air flow apparatus and fixtures appropriate for reproducible plug testing (conditions and calibration described in the standard).
• Procedure steps: packing of the fibre plug, application of prescribed test conditions, measurement recording and calculation/interpretation of maturity indicator(s).
• Interpretation and limitations: method provides an indirect maturity assessment; results can differ for non‑bale lint sources and should be used alongside other quality data.

Typical use and users

Laboratories in textile manufacturing and testing, cotton merchants and ginning operations, spinners and yarn manufacturers, quality assurance teams and researchers use ISO 10306:2014 to assess cotton maturity as part of raw‑material characterization and process control. National standards bodies and conformity assessment organizations adopt the ISO method for harmonized testing.

Related standards

ISO 10306:2014 replaces ISO 10306:1993 (withdrawn). The standard is developed under ISO/TC 38/SC 23 (Fibres and yarns) and is often published/adopted in EN and national variants (e.g., DIN EN ISO, UNE‑EN ISO). Users should consult related textile test standards and national adoption documents for localized editorial changes and additional guidance.

FAQ

Q: What is this standard?

A: An ISO international standard (ISO 10306:2014) that specifies a laboratory method to evaluate cotton fibre maturity indirectly by measuring the resistance to air flow of a plug of cotton fibres.

Q: What does it cover?

A: It covers sample types (primarily bale‑taken loose fibres), the air‑flow measurement principle under two prescribed conditions, test procedure essentials, and guidance on interpretation and limitations of results.

Q: Who typically uses it?

A: Textile test laboratories, cotton traders and ginners, spinners, QA/QC teams and researchers who need a reproducible maturity indicator for cotton fibre quality assessment. National standards bodies also publish/adopt the ISO text for national use.

Q: Is it current or superseded?

A: ISO 10306:2014 is the active, current edition (edition 2) published in 2014 and it replaced the 1993 edition; national adoptions and confirmations should be checked for their current status.

Q: Is it part of a series?

A: It is a standalone test method within the textile test standards developed by ISO/TC 38/SC 23; although not numbered as a multi‑part series, it relates to other cotton and fibre test standards maintained by the same technical committee.

Q: What are the key keywords?

A: Cotton fibres, maturity, air flow method, air‑permeability, textile testing, bale sampling, ISO 10306.
