  • Method for sizing warp yarns
    Patent number: 4009512
    Abstract: A method for sizing warp yarns for yarn dyed fabric. It consists of the first operation of arranging cheeses on a cheese creel for a desired pattern and winding the warp yarns from the cheeses to form a warpers beam, and the second operation of sizing and drying the warp yarns from a plurality of the warpers beams thus formed while winding them on a drum, and rewinding the sized yarns to form a loom beam. In both operations, the warp yarns are passed through a lease reed and a lease cord is set at their ends by use of the lease reed. This makes more efficient the sizing of warp yarns.
