Overview
EN ISO 3175-5:2019 (ISO 3175-5:2019) specifies standardized test procedures for drycleaning and finishing using dibutoxymethane [1-(butoxymethoxy)butane] for fabrics and garments. Part of the ISO 3175 series on professional care, this document defines how to carry out controlled cleaning cycles in commercial drycleaning machines and how to finish specimens prior to performance assessment (as referenced in ISO 3175-1). It covers procedures for both normal and sensitive materials, and includes safety and equipment requirements.
Key topics and technical requirements
- Scope and principle
- Procedure for testing textile performance after cleaning and finishing with dibutoxymethane; intended as a precursor to performance assessment in ISO 3175-1.
- Reagents
- Dibutoxymethane (CAS 2568-90-3) specified (flashpoint 62 °C, boiling point 182.5 °C) and sorbitan mono-oleate as a model detergent/emulsifier.
- Drycleaning machine requirements
- Reversible rotating cage (diameter 600–1 080 mm, depth ≥300 mm) with 3–4 lifters.
- Specified g-factor ranges for cleaning and extraction (g-factor formula provided).
- Controls for solvent and air temperatures, solvent dryness control, solvent temperature measurement ±2 °C, and facilities for controlled introduction of emulsions.
- Procedures
- Distinct workflows for normal materials and sensitive materials (limits on mechanical action, drying temperature, and water addition).
- Conditioning, number of repeated cycles (noting many effects appear after 3–5 cycles), and finishing treatments (steam, pressing) are defined.
- Finishing apparatus
- Iron, steam press, steam table, and steam mannequin (specifications and pressures referenced).
- Documentation
- Requirements for test reporting and referencing normative standards (e.g., ISO 139 for conditioning).
Practical applications and users
- Textile testing laboratories performing standardized drycleanability evaluations.
- Drycleaning equipment manufacturers and solvent suppliers validating processes for dibutoxymethane.
- Garment and textile manufacturers assessing product durability and compatibility with alternative solvents.
- Quality assurance teams, standards bodies, and compliance officers needing reproducible procedures for comparative testing of cleaning and finishing performance.
Related standards
- ISO 3175-1 - Assessment of performance after cleaning and finishing (used in conjunction with Part 5).
- ISO 139 - Standard atmospheres for conditioning and testing.
EN ISO 3175-5:2019 is essential for stakeholders seeking a harmonized, safety-aware method to evaluate professional care processes using dibutoxymethane and to communicate reliable drycleaning performance data.
