  1. Fibrous Assemblies

  2. Now What? • At this point the only choices we have to use what we made by both types of spinning • Monofilament • Sewing thread • So we move up to the next level

  3. Woven Fabrics • Woven fabric • formed by interlacing two distinct sets of yarns • warp – yarns running the length of the fabric, machine direction • weft/filling – yarns running width of fabric, cross direction

  4. Plain weave tightest, strongest every end interlaces with every pick Matte weave good tear and burst resistance ends and picks interlace as groups Woven Fabrics (2)

  5. Twill weave diagonal appearance good tear strength Satin weave excellent tear strength good openness common fabric structure in composites Woven Fabrics (3)

  6. Pile weaves 3-D structure Leno weaves open stable Woven Fabrics (4)

  7. Knitted Fabrics • Two categories • weft knitted • high extensibility widthwise • tubing, hosiery • warp knitted • high dimensional stability • meshes

  8. Plain knitted good widthwise (2x) and lengthwise (1.5x) extension Rib knitted high widthwise (4x) and good lengthwise (1.5x) extension Weft Knitted Fabrics

  9. Warp Knitted-Meshes and Nets

  10. Braids • Diagonally interlaced • strong • torque balanced • sutures • artificial tendons

  11. Nonwovens barriers, suture buttresses, sponges and absorbents, disposables Laminates barriers, protective materials Nonconventional
