Embodiment 1

[0038] (1) Obtain the basic data of the fabric JT / C 65 / 35 45*45 90*76 47"2 / 1 twill weave required by the customer by scanning the barcode; assign the data to the corresponding twill weave according to the basic data of the fabric;

[0039] (2) According to the general representation of fabrics in the world: A B C D*E F*G H calculates the length of the visible segment of the yarn on the warp and weft surface of the fabric, (when it is expressed in imperial system) the space occupied by each warp yarn = 25.4 / 110 = 0.282 mm, The width of the space occupied by each weft yarn = 25.4 / 76 = 0.32 mm, combined with the comparison between the warp and weft yarn fineness and the actual measured value, the corresponding space diameter is 0.25, 0.25 value;

[0040] (3) If the buckling wave problem of warp and weft yarns is considered in each cycle unit, the minimum surface visible yarn lengths are: twill weave 2 / 1: twill warp yarn = (3*25.4 / 90-J)*1.01 =( 3*0.282-0.25)*1.01=0.602, twill wef...

Embodiment 2

[0043] (1) Cut the printed and dyed pictures according to the total number of warp yarns in the weft direction of the fabric pattern: divide the printed and dyed pictures according to the interval between adjacent warp yarns m=(0.282-0.25)*2=0.064 mm The picture obtained after the cutting process is processed, and white strips with a width of 0.064 mm are filled between adjacent cut strips to form a new picture with white stripes;

[0044] (2) For each picture strip after slitting, according to the pattern structure of the fabric and the interweaving law of the corresponding warp and weft directions, the picture strip is regularly cut in the weft direction: according to the law of buckling wave height of warp yarns, and according to the interval between adjacent weft yarns Size n=(0.32-0.25)*2=0.14, at the interweaving point position, the weft yarn is on the top, and the warp yarn is on the middle point of the bottom place, filling the blank gap a with a diameter of 0.25 mm in ...

Abstract

The invention relates to the field of textile printing and dyeing cloth, in particular to an automatic picture adjusting method for online printing and dyeing a yarn sheet with the full-size width. Inorder to solve the problems such as more sewage and low efficiency in digital printing technology application of the yarn-dyed industry in the prior art, the invention provides the automatic pictureadjusting method for online printing and dyeing the yarn sheet with the full-size width. A computer is adopted as a tool, a picture for online printing and dyeing the yarn sheet with the full-size width is automatically and quickly generated based on a target picture, no picture database is needed, and the target picture is copied and moved and a slice picture is reconstructed to a target area, sothat the picture for online printing and dyeing the yarn sheet with the full-size width can be generated.

Description

technical field [0001] The invention relates to the field of textile printing and dyeing garments, in particular to an automatic image adjustment method for online printing and dyeing of whole-width pieces of yarn. Background technique [0002] The yarn-dyed industry is a traditional industry in the textile industry, involving four majors: spinning, weaving, dyeing, and finishing. It is a deep-processing industry that goes through multiple processes and uses a variety of equipment. The main characteristics of the yarn-dyed industry are the long production process, dyeing yarn first, then weaving, and then finishing; the technical span and management span are large, the labor is large, and the management is complicated; the products are deeply processed products, which require small batches, multiple varieties, and fast For delivery, foreign exchange earning per ton of fiber is relatively high; product presentation methods are rich, which is conducive to the development of ne...
