The criteria used to assess fiber and yarn quality inlcude fiber length, cross section, surface structure, fiber or yarn fineness, fiber density, and yarn uniformity. Fiber length determines yarn smoothness and hairiness. Fiber cross section and surface structure determine yarn processability. Both Nm (weight related metric count) and dtex (length related tex count) measure fiber or yarn fineness. Fiber density influcences fiber volume. Fiber structural properties include breaking strength, abrasion resistance, and moisture content. Tensile testing machines plot the fiber stress-strain curve and determine fiber tenacity and breaking elongation. The three types of fabric moisture absorption are adherence to the surface, penetration between filaments, and penetration into the fiber through swelling. State electricity problems relate to the absorption of water into the fiber structure.
