Abstract
A spring dye tube for use in dyeing textile yarns has a generally open-ended, cylindrical configuration with a latticed side wall. It is resiliently compressible in a longitudinal direction, and includes longitudinal stabilizing elements to prevent growth or collapse during high-speed winding operations. In turn, these longitudinal stabilizing elements buckle and collapse when the spring dye tube as a whole is compressed in a longitudinal direction. The longitudinal stabilizing elements may be disposed in pairs separated by a gap, or singly. In the latter case, a longitudinal groove may be provided along the length of the element; the element will split along this groove when the tube is compressed. In either case, this provides a means for dye to pass through that portion of the tube during use in a dyeing operation. The longitudinal stabilizing elements can resemble thin membranes in appearance, the membranes being of greater width than thickness. In yet another case, the longitudinal stabilizing element may cover the entire inner surface of a spring dye tube. The longitudinal stabilizing elements may be incorporated in helical, and other kinds of, spring dye tubes known in the art.
