Colourfastness Testing

Overview

Wash, light, rubbing colourfastness. This technology is used as a controlled building block in garment and textile operations. It provides evidence for product-quality and chemical-compliance decisions.

Applications

• •Apply Colourfastness Testing to the primary use case: wash, light, rubbing colourfastness.
• •Support approval, release, investigation and corrective-action decisions with recorded test evidence.
• •Compare suppliers, lots, colours or process changes using consistent methods and acceptance criteria.

Implementation Guide

• •Define the problem, baseline, owner and measurable acceptance criteria before introducing Colourfastness Testing.
• •Pilot representative styles, materials, colours or production conditions and compare results with the current approved method.
• •Use the correct test method, calibrated equipment, conditioned specimens, trained assessors and documented decision rules.

Considerations & Risks

• •Test method, specimen conditioning, multifibre selection and grading conditions strongly affect results.
• •Sampling plans and laboratory results must be interpreted within their scope, uncertainty and applicable market requirements.
• •Maintain documented ownership, periodic review, exception handling and corrective action as products, suppliers and operating conditions change.
