(Key: E=very poor, D=poor, C=acceptable, B=good, A=excellent)
Plain
- Each warp fibre passes alternatively under and over each weft fibre. (Difficult to drape and high crimp impacts low mechanical properties).
Twill
- One or more warp fibres alternatively weave over and under two or more weft fibres in a regular repeated manner. This produces diagonal rib.
- Superior wet out and drape, over plain, with only a small reduction in stability.
- Reduced crimp gives smoother surface and high mechanicals.
Satin
- Twill weaves modified to produce fewer intersections of warp and weft. The harness (4, 5 & 8) is the total number of fibres crossed and passed over before the fibre repeats the pattern.
- Satin weaves are very flat, have good wet out and a high degree of drape. Low crimp gives good mechanicals. Satin weave allows fibre to be woven in the closest proximity and produces fabrics with tight weave.
- The style has low stability and asymmetry needs to be considered. The asymmetry causes one face of the fabric to have fabric running predominantly in the warp direction, with the other in the weft. Care must be taken when assembling multi layers to ensure that stresses are not built into the component through this effect.
