TS 111 Lecture Notes - Lecture 4: Metallic Fiber, Spinning Wheel, Monofilament Fishing Line
Document Summary
Women spinning flax use a drop of spindle and distaff. First spinning wheel developed in india: classification of simple yarns. Spun yarns: napping twist: 3-4 twist per inch & brushed after for smooth surface, average twist: enough twist to lay smooth, voile twist: thin tightly twisted, semi-transparent, crepe twist: so much twist that fabric would twist and curl. Filament yarns: synthetics: smooth-filament yarn, low twist: duller, crepe twist, textured- bulk yarn, low twist, filament yarns. Monofilament, multifilament and microfilament yarns: plying: when yarn twist and folds together and becomes stiff, yarn twist. Turns-per-inch (tpi): 1inch=2. 45 cm: soft twist or hard twist - spun yarns, crepe-filament yarns. Twist direction: s twist: spirals run up and left like the letter s , z twist: spirals run upward to the right like a z . Directions of the twists affects the appearance on the surface: novelty yarns. Carded and mix in other fibers into yarns: yarns are spotted or have designs this way.
