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

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

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

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

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

9. Warp Knitted-Meshes and Nets

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

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