Methods of Warping Processing (Part Two)
3. Sectional Warping
The process of first winding a portion of the warp required for the full width of the fabric onto a narrow small warp shaft, and then simultaneously unwinding several narrow small warp beams into a wide warp beam. In order to weave fabrics with symmetrical pattern arrangement, the rotation of each narrow warp shafts can be arranged with clockwise and counterclockwise intervals. If several narrow and small warp shafts are threaded side by side on the shaft tube, they can form a weaving shaft for warp knitting machines and weaving machines. Mainly used for warp processing of symmetrical and repetitive patterns, which can improve production efficiency.
4. Ball Warping
This warping process involves dividing the total number of warp pieces required for a full width fabric into several bundles based on the capacity of the creel. Each bundle is then bundled and wound into a spherical yarn ball, which is then dyed by a rope dyeing machine in the later stage, and then rolled into a warp beam by the warping machine. After sizing the warp beam, it is synthesized into a woven beam. It can directly process the dyed ball warp for warping, and is mainly used for pre weaving warp preparation of denim.
