  2. b produces a yarn that is superior to a carded yarn in smoothness, fineness, evenness, and strength
  3. c made from manufactured fibers, except for the tiny percentage that is filament silk
  4. d less slipery, less smooth, more absorbant, more breathable, more comfortable

  2. cardingpartiallyu aligns the fibers and forms them into a thin web that is brought together as a soft, very weak rope


  3. bulk yarns have betterbulk, cover, elasticity, electrical conductivity


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


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