Overview

ISO 105-F05:2001 - Textiles - Tests for colour fastness - Part F05 specifies an undyed acrylic adjacent fabric used to assess staining in colour fastness tests. The document defines the physical and optical properties the acrylic adjacent fabric must meet, the comparison procedure using a reference adjacent fabric and a dyed reference fabric, and the acceptance criteria for reproducible staining behavior. Reference materials are obtainable from a specified supplier (AATCC).

Key topics and technical requirements

• Purpose: Standardizes an acrylic adjacent fabric for use in colour fastness/staining assessments to ensure reproducible test results.
• Physical property: Mass per unit area: 135 ± 5 g/m² (measured per ISO 3801).
• Optical properties: Specified luminance/whiteness/tint values measured with specular included using CIE standard illuminant D65 and the CIE 1964 10° observer per ISO 105-J02 and ISO 105-J01. Target values (as given in the standard) are approximately:
  • Y10 ≈ 86 ± 2
  • W10 ≈ 67 ± 2
  • T10 ≈ 1 ± 1 (i.e., about 0–2)
• pH requirement: Aqueous extract pH = 7 ± 0.5 (ISO 3071).
• Staining assessment procedure: Test composite specimens comprising the acrylic dyed reference fabric sandwiched between the acrylic adjacent fabric under test and the acrylic reference adjacent fabric; perform the intermediate steam-pleating test per ISO 105-P02 (115 °C, 10 min, 170 kPa).
• Performance criterion: Colour difference between stains on the test and reference adjacent fabrics must not exceed 4–5 on the grey scale for assessing change in colour (ISO 105-A02).
• Supply note: Acrylic reference adjacent fabrics and dyed reference fabrics (dyed with C.I. Basic Green 4) are available from the specified source (contact AATCC).

Applications and users

Who benefits from ISO 105-F05:2001:

• Textile test laboratories performing colour fastness and staining evaluations.
• Fabric and yarn manufacturers establishing quality control for acrylic materials.
• Dye houses and colorant formulators validating staining transfer characteristics.
