(3) Stripping warping is also called belt warping. This method of warping is based on the yarn arrangement cycle and the capacity of the creel, dividing the total number of roots required for the full-width fabric into as many strips as the number of roots as possible, and then sizing the strips according to the process width. The length is wound in parallel onto the warping drum. Then, the entire warp yarn strip is simultaneously unwound from the warping drum to the weaving shaft by the reverse shaft mechanism. This process of unwinding onto the weaving shaft is called a reverse shaft.
The warp yarn adopting the split warping method generally does not need sizing, and directly forms a weaving shaft for weaving by the weaving machine after warping, thereby shortening the process flow. The slitting warping is suitable for the warping of multi-color yarns or different twisting yarns. The pattern arrangement is convenient and the yarn return is small. It is especially suitable for the production of small batch and multi-variety fabrics. The disadvantage is that the production efficiency and speed are low. Slitting warping methods are widely used in yarn-dyed, towel, silk, wool and other industries.
(4) Sectional warping. Sectional warping firstly winds the warp yarns required for the full-width fabric on several narrow small warp beams according to the process requirements, and then puts several narrow small warp beams side by side on the mandrel. The warp yarns of the warp beam are simultaneously unwound onto the weaving shaft. The total width of several narrow warp beams is the same as the width of the woven shaft, and the winding density is also the same, which can save the truss footprint. This method of warping is mostly used in the production of symmetrical flower fabrics and the production of warp knit fabrics.
