Sample interview questions: What techniques and equipment do you typically utilize for shrinkage and dimensional stability assessment?
Sample answer:
Techniques for Shrinkage Assessment:
- Immersion Method (ISO 6330): Fabric is immersed in water or a controlled atmosphere to assess its shrinkage in length and width.
- Tumble Drying Method (AATCC 135): Fabric is tumbled in a dryer to simulate home laundering conditions and measure its shrinkage.
- Hot Air Oven Method (ASTM D1905): Fabric is exposed to high temperatures in an oven to induce shrinkage and determine its thermal stability.
- Dimensional Change Analyzer (DCA): Advanced equipment that monitors fabric dimensions under controlled temperature and humidity conditions, providing precise shrinkage measurements.
Techniques for Dimensional Stability Assessment:
- Yarn Crimp Test (ASTM D3883): Measures the amount of crimping in yarns, which can influence the fabric’s dimensional stability.
- Set-Reducing Treatment (ASTM D1774): Fabric is treated with chemicals or enzymes to remove stresses that may cause dimensional changes.
- Wrinkle Recovery Angle (ISO 6330): Assesses the fabric’s ability to recover from wrinkles… Read full answer
