Overview
ISO 17299-1:2014 - Textiles - Determination of deodorant property - Part 1: General principle - defines the general principles for testing the deodorant property of textile products. The standard applies to woven and knitted fabrics, nonwovens, fibres and yarns, braiding products, tapes and slings. It establishes the conceptual framework, terminology, test environment and calculation of odour reduction used by the instrument and sensory methods described in ISO 17299‑2 to ISO 17299‑5.
Key topics and technical requirements
- Scope and definitions: Clear definitions for terms such as unpleasant odour, deodorant textile, deodorant substance, quasi‑unpleasant odour and deodorant property. Major odour chemicals are listed (e.g., ammonia, acetic acid, isovaleric acid, nonenal, hydrogen sulfide, methyl mercaptan, indole).
- Principle of measurement: The deodorant property is evaluated by measuring chemical concentrations in a closed container with a specimen (A) and without a specimen (B). The odour reduction rate (ORR) is calculated as ORR = (B − A) / B × 100 %.
- Testing environment and conditioning: Specifies sample conditioning and test atmosphere per ISO 139 - typical conditions cited are 20 °C, 65 % RH (an alternative 23 °C, 50 % RH may be used and must be reported).
- Reagents and target chemicals: Lists reagents and representative odour chemicals used for tests (ammonia, acetic acid, isovaleric acid, 2‑nonenal, indole, hydrogen sulfide, methyl mercaptan), and recommendations for analytical‑grade materials and diluent gases.
- Materials and apparatus: Typical equipment includes small-volume plastic bags (1–50 L), air pumps and integrating flow meters, syringes and micro‑syringes, aspirators/vacuum pumps, heat sealers, ovens and standard gas generators.
- Test reporting and interpretation: Requires reporting method reference, sample identification, individual concentration data, averages, reduction rate and any deviations. Annex E provides practical reference guidance for deodorant textile certification (informative).
Practical applications and users
- Who uses it: textile manufacturers, research & development teams, independent test laboratories, quality assurance and certification bodies, and product compliance teams.
- Why it’s useful: standardizes the objective evaluation of deodorant textiles to:
- support product development and formulation of deodorant treatments;
- verify marketing claims for odour reduction;
- provide consistent laboratory procedures for quality control;
- enable certification and comparative performance assessment across products.
- Common use cases: evaluating treated fabrics, comparing deodorant finishes, substantiating consumer claims (e.g., anti‑odour garments), and supporting regulatory or procurement specifications.
