Abstract: The finishing variables are coded in accordance with Refence 1,whichseeforcomplete details. Dear Sir: Let us define a completely set fabric as one in which the yarn crimp is set. When yarn is removed from a completely set fabric, no change in the yarn shape should occur. On removal from a completely unset fabric, the yarn should assume its original, straight uncrimped condition. The tendency for the yarn in an unset fabric to return to its unwoven state leads to reaction force Q between crossing warp and fill yarns. As the degree of setting of a fabric increases, this reaction force will decrease. For a completely set fabric, the reaction force will be zero. This reaction force affects various mechanical properties of the fabric as follows: as Q decreases, the bending and shear stiffness increase while extensibility and hygral expansion increase. Kirrholm, Cednas, and Nordhammar [1] have published extensive data on fabrics finished in different ways. It is possible that variations in measured properties of these fabrics can be partly attributed to differences in Q resulting from different degrees of set. It is appreciated that other factors contribute to these differences, but in the analysis to be described, it is ~ttempted to isolate the effect of Q. These data enable us to rank the finishing treatments for their setting effects, using the above given effects of the inter-yarn reaction force Q which should decrease as the setting increases. A treatment is given a score of 1 for each treatment which has an apparently lower Q and a score of i for each treatment with apparently the same Q. For each property (bending stiffness, shear stiffness, extensibility, and hygral expansion) to guide the choice of whether increasing or decreasing magnitude of the property is to be associated with increasing Q.
