A kind of warping method of section warping

Abstract

The invention provides a warping method for section warping, which belongs to the technical field of fabrics. A warping method for warping by strips, comprising the following steps: S1, accurate calculation: confirm the number of warp arrangement cycles of the target warp axis, the number of strips in each warp arrangement cycle, the width of each strip, the The length and weight of each warp bobbin; S2, unit division: divide into a plurality of large units and / or small units by a warp arrangement cycle of the target warp beam; S3, unit processing; S4, upper row arrangement; S5, whole by order. The invention has the advantages of simple operation and low-cost warping of warp beams that can satisfy the large warp arrangement cycle.

Description

technical field [0001] The invention belongs to the technical field of fabrics, in particular to a warping method for section warping. Background technique [0002] The section warping method is to divide the total number of warp yarns required by the full-width fabric into several strips, and then wind them on the warping drum in turn, and finally wind the full-width warp yarns on the warping drum to the on the weaving shaft. When this method is used for warping of multi-colored or different twisted warp yarns, it is more convenient to arrange the colored warps. It is widely used in the production of small batches and many varieties of yarn-dyed, woolen and silk weaving. [0003] However, the number of bobbins on the general creel of the section warping machine is about 480 to 560, and the maximum number is not more than 720. The upper row of bobbins should be replaced according to the requirements of the warp line arrangement before a belt, and each replacement of the u...

Problems solved by technology

[0003] However, the number of bobbins on the general creel of the section warping machine is about 480 to 560, and the maximum number is not more than 720. According to the requirements of the warp arrangement before a belt, the upper row of bobbins should be replaced again, and each replacement of the upper row of bobbins takes at least 2 hours, which not only seriously reduces efficiency, but also wastes raw materials

For example, if a warping machine with a maximum of 480 bobbins has a total warp number of 9,600 target warp beams, it only takes 40 hours to change the bobbins, which will seriously restrict the small batch, multi-variety, short-frequency and fast core competitiveness
