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
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
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
Woven Fabrics (3)• Twill weave
– diagonal appearance– good tear strength
• Satin weave– excellent tear strength– good openness– common fabric structure in
composites
Woven Fabrics (4)
• Pile weaves– 3-D structure
• Leno weaves– open– stable
Knitted Fabrics
• Two categories– weft knitted
• high extensibility widthwise• tubing, hosiery
– warp knitted• high dimensional stability• meshes
Weft Knitted Fabrics
• Plain knitted– good widthwise (2x)
and lengthwise (1.5x) extension
• Rib knitted– high widthwise (4x) and
good lengthwise (1.5x) extension
Warp Knitted-Meshes and Nets
Braids
• Diagonally interlaced– strong– torque balanced– sutures– artificial tendons
Nonconventional• Nonwovens
– barriers, suture buttresses, sponges and absorbents, disposables
• Laminates– barriers, protective
materials
