Abstract
An attempt was made to convert the conventional sizing machine into a smaller-sized unit suitable mainly to yarn-dyed fabrics by simplifying the dryer and using a new type sizing liquor for warp sizing.
Results: We have succeeded in making a model warp sizer. Sizing by this machine goes through three stages: (1) applying sizing liquor (which contains starch granules) to the yarn; (2) gelatinizating starch on the yarn by steaming; and (3) drying. We name this sizing method “semi-dry sizing”.
We expect this method will come into wide use because it can be used not only for dyed yarns but also for yarns hitherto not sized by sheet-sizing, especially flutty yarns.
