  1. spun yarns have
  2. combination
  3. a blend
  4. spun yarns have protruding ends that
  5. combing
  1. a produces a yarn that is superior to a carded yarn in smoothness, fineness, evenness, and strength
  2. b prevent close contact with the skin which makes spun yarn fabric more comfortabe
  3. c a fuzzy surface, greater amounts of twist compared to filament yarns, short fibers that pull apart, and partially parallel fibers
  4. d is an intimate mixture of fibers of different generic type, composition, length, diameter, or color spun together into one yarn
  5. e ply yarns are used and at least one ply yarn is of a different generic fiber type from the other strands of the ply yarn

5 Multiple choice questions

  1. are uniform as they come from the spinneret. their smooth nature gives them more luster than spun yarns
  2. more texture or crimp, and do not pill or shed
  3. no protruding ends, so they do not lint
  4. bulk, cover, elasticity, electrical conductivity
  5. partiallyu aligns the fibers and forms them into a thin web that is brought together as a soft, very weak rope

5 True/False questions

  1. bulk yarnone that has been processed to have greater covering power or apparent volume than that of a conventional yarn of equal linear density and of the same basic material with normal twist


  2. compactness is a disadvantage inopening, carding, drawing, combing or worsting, roving


  3. drawingincreases the parallelism of the fibers


  4. mixtureincreases the parallelism of the fibers


  5. rovingreduces the drawn silver, increases the parallel alignment of the fibers, and inserts a small amount of twist in the strand, now called roving
