  22.  
  23. Chapter 3
  24. 1. Definition of Standard test methods.
  25. Visual inspection:
  26. Burn test: identify fibers chemical composition. Distinction between cellelosic, protein, mineral and synthetic
  27. microscopy: look under microscope at physical structure
  28. solubility test: fiber in solvent note effect
  29. 2. What does the physical structure of a fiber refer to?
  30. Length, diameter, cross-sectional shape, surface contour, crimp, fiber parts
  31. 3. What do aesthetic properties refer to? (for instance, Luster, Drape, Texture, Hand)
  32. Cover: ability to protect or conceal
  33. Luster: way light is reflected by a surface
  34. Drape: way fabric falls over a 3d form
  35. texture: nature of textiles surface
  36. hand: way textile feels to the skin
  37. 4. What do durability properties refer to?
  38. Abrasion resistance:
  39. Flexibility: ability to bend repeatedly without breaking
  40. Pilling: formation of balls under fabrics surface
  41. strength: ability to resist stress
  42. tenacity: tensile strength. Ability to withstand pulling force
  43. cohesiveness: ability of fibers to cling together during spinning
  44. elongation: ability of fiber to be stretched without breaking
  45. 5. What do comfort properties refer to?
  46. Absorbency: ability of fiber to take moisture from body
  47. hygroscopic: fibers absorb moisture without feeling wet
  48. electrical conductivity: absorbent fibers do not build up static charge
  49. wickingL ability of a fiber to transfer moisture along its surface. Wick well not absorbant
  50. heat / thermal rentiton: ability of textile to hold heat
  51. heat condfucity: ability to transfer heat through a fabric
  52. heat sensitivity: fibers reaction to heat
  53. flammability: fabrics reaction to ignition and how it burns
  54. density / specific gravity: measure of fiber weith per unit of volume
  55. alergic potential
  56. 6. What do appearance-retention properties refer to?
  57. 7. List four common fiber identification methods.
  58. Burn test, soluability test, visual instection, microscopy
  59. Chapter 4
  60. 1. List the properties that are common to all natural cellulosic fibers.
  61. Good absorbency, conductor of heat, withstand high temp, low resiliency, low loft
  62. , good conductor of electricity, heavy fibers, moderate resistance to sublight
  63. 2. Explain the serviceability of cotton.
  64. Aesthetics: range
  65. durability: medium strength, stronger in water, low enlogation/ elasticity, abrisian resistance good
  66. comfort: moisture passes freely good heat and electrical conductivity, soft hand
  67. appearance retention: low resiliency – wrinkles, shrinks
  68. care: bleach weakens, stronger in water
  69. 3. Understand the types of cotton according to farming methods.
  70. 4. Explain the serviceability of flax.
  71. 5. Citing serviceability concept, explain the pros and cons of use of cotton in sportswear.
  72.  
  73. Chapter 5
  74.  
  75. 1. Explain the characteristics common to all natural protein fibers.
  76. 2. Understand the serviceability of wool.
  77. 3. Understand the serviceability of silk.
  78.  
  79. 4. What chemical can be used to effectively remove the overlapping scales on the surface of wool so as to improve the smoothness, softness and fineness of wool?
  80.  
  81. 5. Explain why most wool products are labeled dry clean only.
  82. 6. Why is silk considered the standards for appearance for many synthetic and manufactured fibers?
