ISO 3175-5:2019

Overview

ISO 3175-5:2019 - Textiles - Professional care, drycleaning and wetcleaning of fabrics and garments - Part 5 - specifies standardized drycleaning procedures using dibutoxymethane (1-(butoxymethoxy)butane) in commercial machines. The standard provides test methods for normal and sensitive materials, defining how to clean, rinse, dry and finish specimens to evaluate performance after treatment. It is intended as a reproducible test procedure prior to assessment under ISO 3175-1.

Key topics and technical requirements

• Scope and principle
  • Drycleaning method using distilled dibutoxymethane and controlled finishing; used as precursor to performance assessment.
• Reagents
  • Dibutoxymethane (CAS 2568-90-3) and sorbitan mono-oleate (model detergent/emulsifier). Emulsion recipes and detergent charge levels are specified.
• Apparatus and machine parameters
  • Commercial drycleaning machine requirements: cage diameter (600–1 080 mm), depth (≥300 mm), lifters, controlled g-factor, solvent and air temperature control, dosing apparatus and automatic solvent dryness control.
  • Finishing equipment: iron, steam press, steam table, steam mannequin/cabinet - steam at ~500 kPa where applicable.
• Test specimen and conditioning
  • Conditioning in standard atmosphere (20 °C, 65 % RH per ISO 139). Specimen sizes and composite specimen definitions provided; ballast composition and load-mass rules described.
• Procedure essentials
  • Liquor ratio (5.0 ± 0.5 l/kg), solvent temperature (30 ± 3 °C), emulsion preparation for normal process (detergent concentration ~3 g/l, 2 % water by mass), rinse and drying cycles, extraction times, minimum number of cycles (three unless agreed), and detailed finishing options (methods A–F).
• Reporting
  • Test report requirements and documentation of any deviations from the specified procedure.

Applications and who uses it

• Textile testing laboratories and quality control teams assessing drycleanability and post-treatment textile performance.
• Drycleaning equipment manufacturers and solvent suppliers validating machine compatibility with dibutoxymethane.
• Garment and textile manufacturers specifying recommended professional care instructions for labels and compliance.
• Research & development for solvent-based cleaning processes and comparative studies of cleaning performance for normal vs. sensitive materials.
• Regulatory bodies and standardization committees referencing a reproducible method for safety and performance claims.

Related standards

• ISO 3175-1 - Assessment of performance after cleaning and finishing (used together with Part 5).
• ISO 139 - Standard atmospheres for conditioning and testing textiles.
• The ISO 3175 series covers broader professional care and wetcleaning/drycleaning test methods.
