Overview
ISO 105-F04:2001 is an international standard developed by ISO (International Organization for Standardization) that specifies the requirements for polyester adjacent fabric used in colour fastness testing of textiles. This part of the ISO 105 series focuses on an undyed polyester adjacent fabric employed for assessing staining during colour fastness tests. The fabric’s staining properties are evaluated relative to a polyester reference adjacent fabric, using a polyester dyed reference fabric.
The purpose of this standard is to ensure consistency and reproducibility in colour fastness testing results, which is essential for quality control in textile production and testing laboratories.
Key Features
-
Specification of Undyed Polyester Adjacent Fabric
The standard defines precise physical and chemical characteristics for the adjacent fabric, including mass per unit area and pH level.
-
Standardized Assessment Method
Staining properties of the polyester adjacent fabric under test are compared against a certified polyester reference adjacent fabric using a dyed reference fabric (dyed with C.I. Disperse Red 4).
-
Performance Requirements
The colour difference in staining between the test fabric and the reference fabric must not exceed the limits defined by the grey scale for assessing change in colour, ensuring reliable test outcomes.
-
Measurement Criteria
Specifications include whiteness values and luminance measured under defined conditions with CIE standard illuminant D and 10° colorimetric observer methods.
-
Normative References
The standard refers to other ISO documents for grey scale evaluation, pH determination, mass measurement, and instrumental color assessment, ensuring comprehensive consistency with related testing procedures.
Applications
-
Textile Industry Quality Control
ISO 105-F04:2001 is critical for manufacturers and testing laboratories conducting colour fastness testing on polyester fabrics to determine staining and colour transfer resistance.
-
Product Development and Compliance Testing
It supports product development by ensuring that any fabric used adjacent to dyed polyester in garments and furnishings meets strict staining control, preventing colour contamination.
-
Laboratory Standardization
The standard facilitates uniform testing environments, enabling labs globally to compare results reliably and verify performance against international benchmarks.
-
Supplier Qualification
Polyester adjacent fabrics meeting this standard are verified for their staining properties and can be confidently used when evaluating other textiles for commercial and regulatory purposes.
