Overview
ISO 105-F09:2009 is an international standard developed by ISO focusing on textiles and their color fastness properties. Specifically, it defines the specification for cotton rubbing cloth used in tests that assess color fastness to rubbing. The standard ensures that the cotton rubbing cloth used in such tests has consistent and reproducible staining characteristics, which is pivotal for accurate evaluation of fabric color durability. This standard is essential for textile manufacturers, quality control laboratories, and testing facilities aiming to verify resistance of dyed textiles to rubbing or abrasion.
Key Topics
-
Cotton Rubbing Cloth Specification
The standard defines precise physical and chemical properties for cotton rubbing cloth to be used in color fastness tests, including:
- Mass per unit area: (110 ± 5) g/m²
- Whiteness value measured with specific illuminant and observer conditions (Y = 89 ± 2)
- Residual oil content below 1%
- pH value of aqueous extract: 7.5 ± 1.0
-
Staining Properties Assessment
Testing the staining behavior of the cotton rubbing cloth against a reference fabric dyed with C.I. Direct Blue 71 ensures that the cotton rubbing cloth under test produces comparable and reliable results. This includes:
- Using standardized testing methods according to ISO 105-X12 (Colour fastness to rubbing)
- Comparison against a designated cotton rubbing cloth reference fabric
- Color difference evaluation utilizing the grey scale method for assessing change in color (ISO 105-A02 or ISO 105-A05), with a permitted maximum difference of 4-5 units
-
Standardized Testing Procedures
The standard mandates specific methods for measurement of whiteness, pH, mass per area, and staining property assessment to help maintain test consistency and accuracy worldwide.
Applications
-
Textile Quality Control
ISO 105-F09:2009 is critical for manufacturers and testing labs performing color fastness to rubbing tests on cotton fabrics and other textiles, ensuring uniformity in test materials.
-
Research & Development in Textile Industry
Enables development of improved textile products with verified color durability and helps in evaluating new dyeing or finishing processes.
-
Certification and Compliance
Supports compliance with international color fastness requirements, helpful for exporting textiles to global markets where ISO certifications are recognized.
-
Material Sourcing
Defines the standards for cotton rubbing cloth which can be sourced from approved suppliers, guaranteeing consistency in test materials.
Related Standards
ISO 105-F09:2009 works in conjunction with several other ISO standards related to textile color fastness testing:
- ISO 105-X12 - Test for color fastness to rubbing, detailing the test method where the cotton rubbing cloth is applied.
- ISO 105-F02 - Specification for cotton and viscose adjacent fabrics used in fastness tests.
- ISO 105-A02 & ISO 105-A05 - Grey scale and instrumental assessment methods for evaluating color change.
- ISO 105-J01 & ISO 105-J02 - Guidelines for measurement of surface color and relative whiteness.
- ISO 3071 - Determination of pH for aqueous extracts from textiles.
- ISO 3801 - Methods for determining fabric mass per unit area.
These complementary standards collectively ensure comprehensive evaluation of textile color fastness properties from sample preparation to result interpretation.
Using ISO 105-F09:2009 ensures reliable, reproducible testing conditions for color fastness to rubbing, providing essential data for textile manufacturers and testers to maintain product quality and meet international expectations for color durability.
