Spin Finish analysis in the manufacture of textile yarns is essential to process control and quality of the final product.
Spin finish is one of the names of liquid coatings applied at a variety of stages in the manufacturing process to control a number of properties including the coefficient of surface friction and electrostatic charge while producing synthetic fibres like polyester, polypropylene, polyamide, acrylic, amongst others.
It is also important that fabric and derivative manufacturers measure spin finish when receiving the raw material, as this influences the quality of the final product in its manufacture.
SpecFIT uses nuclear magnetic resonance (NMR) technology to measure the amount of coating oil finish in a fiber or fabric sample. In essence we measure the amount of hydrogen nuclei relative to the coating oil finish in a sample. That makes the NMR a reliable technique with simple steps to follow.
