Overview
ISO 105-F07:2001 specifies an undyed secondary acetate adjacent fabric intended for use in colour fastness testing of textiles. The document defines the fabric’s physical and optical properties, the method for assessing its staining behaviour using a dyed reference fabric, and the acceptance criteria needed to ensure reproducible results in colour fastness (staining) tests.
Key topics and technical requirements
- Purpose: Provide a standardized adjacent fabric for assessing staining in colour fastness tests, ensuring consistent and comparable results.
- Reference materials:
- Secondary acetate dyed reference fabric (dyed with C.I. Disperse Red 1).
- Secondary acetate reference adjacent fabric (for comparison).
- Sources for these reference materials are identified (contact AATCC as noted in the standard).
- Physical requirement:
- Mass per unit area: (160 ± 5) g/m², measured in accordance with ISO 3801.
- Optical and chemical requirements:
- Specified luminance, whiteness and tint values to be measured using CIE standard illuminant D65 and the CIE 1964 10° observer per ISO 105-J02 and ISO 105-J01 (specular included, excluding 0/45 or 45/0 geometry).
- pH of the aqueous extract: 7.0 ± 0.5, determined by ISO 3071.
- Assessment procedure:
- Construct a composite specimen with the dyed reference fabric placed between the adjacent fabric under test and the reference adjacent fabric; test the specimen according to ISO 105-C02 (colour fastness to washing).
- Both adjacent fabrics should be used in the same composite specimen to eliminate procedural differences.
- Performance criterion:
- The colour difference between stains on the test and reference adjacent fabrics shall not exceed grade 4–5 when assessed using the grey scale for assessing change in colour (ISO 105-A02).
Applications and users
- Intended for textile testing laboratories, quality assurance teams, textile manufacturers, dye houses and suppliers of adjacent/reference fabrics.
- Practical uses include:
- Standardizing adjacent fabric behaviour in colour fastness (staining) evaluations.
- Supporting reproducible inter-laboratory comparisons and product quality control.
- Procurement and verification of secondary acetate adjacent fabrics for test laboratories.
