Abstract
Summer-weight wool-rich blend fabrics with different warp and weft bending char acteristics are produced by weaving weft yams consisting of fine wools blended with bicomponent synthetic polyester or polyolefin fibers into pure wool warps. The differ ential bending properties of the fabrics are developed during finishing. The effects on the bending and shear characteristics of the fabrics are considered after each stage of the finishing sequence. Wool/polyester fabrics are more susceptible to the effects of steaming during finishing than wool/polyolefin blends. Conditions during finishing must be carefully controlled if the optimum fabric properties are to be obtained. Trials confirm that summer-weight fabrics with engineered bending and shear characteristics can be produced from blends of wool with bicomponent synthetic fibers by choosing suitable finishing sequences.
