Categories

  1. Mechanical: finishes applied mechanically rather than chemically.

  • Effect size and appearance
  • Ex: Glazing, embossing, cutting.

  1. Chemical: finishes that become part of the fabric through chemical reaction.

  • Affect performance
  • Ex: flame resistant, stain resistant, waterproof, preshrunk
