Abstract:
A device for twisting natural and synthetic fibre yarns together into a single thread, comprising a double-twist receiving spindle made vertical with a horizontal winding drum; a cabling bath with an impregnating fluid mounted under said receiving spindle; and double-twist delivery spindles mounted under the bath so that the axes of rotation of their disks are disposed in different planes passing through the axis of rotation of the receiving spindle''s disk, and each of these axes is equally spaced from said axis of rotation.
Abstract:
A method to produce highly stretchable twisted cotton yarn, wherein a single yarn is plied in two or more folds, and twisted in the direction of the single yarn twist, then the resulting plied yarn is treated in a bath with an alkaline solution, neutralized by acid, and water-washed, whereupon the yarn is impregnated with thermosetting resins, squeezed, dried, heat cured, and then straightened out and untwisted, thereby giving it a twist in the direction opposite to that of the plied yarn, thereby to produce a highly stretchable twisted cotton yarn.
