It may be taken as a maxim that if there is reason to suspect any difference in the nature of the blend spun, means should be taken effectually to mix the yarn produced in the creel when used for warp, and to weave in order-spindle by spindle and doffing by doffing—if for weft, employing a loom box mixing apparatus if possible. Unless yarns are going to be most thoroughly mixed in the subsequent operations—and this is possible only in the case of warping and not always then-it is better to consider that :- (a) There will be a slight difference between the product of spindle and spindle ; (6) There will be a marked difference between the product of doffing and doffing ; and to subsequently treat yarns with these differences fully in view. The several types of winding machines are treated in Chapter XIII. Fancy Woollen Yarns.-Fancy woollen yarns may be produced by one or more of the following methods :- 1. By structural irregularities (carding or spinning) in the single yarn ; 2. By “nicker," "fleck" or "slub" additions on the card to the single yarn ; 3. By sectional feed and irregular doffing or some such carding arrangement, yielding "random” effects; 4. By fancy twisting conveniently studied under :- (a) Irregular or “cloud” twists; L 161
