Woven fabric constructed
Weft yarns run horizontally, warp vertically. Interlocking yarns at right angles.
Knitting construction
Weft knitting: interlocking loops formed horizontally and can stretch but may unravel easily.
Warp knitting: interlocking hoops vertically, it keeps shape and less likely to unravel
Bonded
Adhesives used
Felting
High heat and high pressure and moisture
Strength
Ability to withstand tension
Hardness
Ability to withstand abrasion, scratching or denting
Thoughness
Ability to absorb impact without breaking or snapping
Malleability
Ability to permanently deform without snapping etc.
Ductility
Ability to be drawn out into thin lengths
Elasticity
Ability to bend and return to shape
Density
Mass of material per unit vol
Absorbancy
How much moisture it can intake
Fusibility
Ability to change liquid or molten state when heated
Electrical conductivity
Ability to conduct electricity
Thermal conductivity
Ability to conduct heat
