Concept
This weaves are characterized by rounded cords with fine sunken lines between them.
The distinction between a Bedford cord is that in the former the cord runs along the length of the cloth.
Principle of the construction of Bedford
See Fig. 4.25. The face of the cord is generally a plain weave. The rounded cord effect is achieved by pair of weft threads floating across the back of the cord and being woven in to form the sunken lines.
Weave drawn
The Bedford weaves are constructed by combining a long float weft rib as base weave and plain or basic twill as face.
Improvement
1) Put two weft floats together in order to accentuate the effect of the cord. See previous Fig. 4.25.
2) The rib is accentuated through adding cutting ends in plain weave on either side of the cord, and by proper denting in separating them by the splits of the reed. See Fig.4-27.(it is essential to select a strong yarn for the cutting ends)
3) Wadding ends are used to give the cord further stability and help to prevent it from becoming flattened. See Fig. 4.28.
4) Further emphasis can be achieved by using a harder twist for the weft, which will shrink more in the finishing.
APPLICATIONS OF BEDFORD CORD
These cord effects are commonly used in upholstery material and light weight Bedford cord suitable for dresses, neckwear, fancy scarf and vests.
