Physical Chemist Consultant: Fiber Structure Development, Fiber Characterization and Fiber Process Development

Technical Consultant #1567


Expertise

  • Organic fiber manufacturing process and fine structure and property relationships.
  • Real time in process structure measurement: X-ray and Raman.
  • Fiber characterization, both fine structure and macroscopic properties.
  • Translation of fiber fine structure to functional properties, e.g. tensile, dye, elongation.
  • Translation of fiber properties to final product strength in spun yarns and spun-bonded non-wovens.
  • Staple yarn spinning (OES), process characterization, product development.
  • Processing, structure, property relationships of PET (polyethylene terephthalate), aromatic polyamide (PPT, Kevlar®), 6,6 nylon and carbon fibers.
  • Testing philosophy and selection of tests appropriate for product release.
  • PP (polypropylene) oxidative stabilization.
