TTQC Lab
Apply international standards to test fibers, yarns, and fabrics — mastering color fastness, strength, abrasion, and statistical quality control.
By the end of this lab course, students will be able to:
- Understand Standards & Testing Procedures
- Apply international standards (ISO, ASTM, AATCC, BSI) in textile testing.
- Follow correct sampling methods and conditioning of test specimens.
- Test Fiber Properties
- Measure fiber fineness, length, maturity, moisture regain, and tensile strength.
- Interpret results in relation to yarn and fabric performance.
- Evaluate Yarn Characteristics
- Test yarn count, twist, strength, elongation, and evenness.
- Identify common yarn faults and relate them to production processes.
- Analyze Fabric Properties
- Conduct strength tests (tensile, tear, bursting), abrasion, pilling, crease recovery, and dimensional stability (shrinkage).
- Assess comfort-related properties (air permeability, absorbency, drape).
- Assess Color & Fastness
- Perform color measurement with spectrophotometers/colorimeters.
- Test fastness to washing, rubbing, perspiration, light, and heat.
- Apply Statistical Quality Control (SQC)
- Use mean, standard deviation, CV%, and control charts to analyze test data.
- Apply acceptance sampling and tolerance limits in quality evaluation.
- Develop Practical & Industrial Skills
- Operate textile testing instruments safely and efficiently.
- Prepare test reports with proper interpretation for industrial application.
