Embodiment 1

[0039] In this embodiment, a method for obtaining the length of the blank segment covered by warp and weft yarns of the fabric, the steps are:

[0040] Obtain the basic data of the fabric required by the customer by scanning the barcode JT / C 65 / 35 45*45 110*76 47"1 / 1 plain weave; the space occupied by each warp yarn = 2.54 / 110 = 0.22 mm, and the space occupied by each weft yarn = 2.54 / 76=0.32 mm, combined with the warp and weft yarn fineness and the actual measurement value, the corresponding space diameter is 0.25,0.25 value, if the buckling wave problem of the warp and weft yarn is not considered in each cycle unit, the smallest surface is invisible blank yarn The thread lengths are: plain weave 1 / 1: plain weave warp = 0.25, plain weft = 0.25; the data of various blank segments obtained is automatically constructed into database X for later call and correction. According to the data of database X, the customer's pattern picture is divided, After digital printing and jet pr...

Embodiment 2

[0042] In this embodiment, a method for obtaining the length of the blank segment covered by warp and weft yarns of the fabric, the steps are:

[0043] Obtain the basic data of fabrics required by the customer through telephone communication JT / C 65 / 35 45*45 110*76 47"2 / 1 twill; the space occupied by each warp yarn = 2.54 / 110 = 0.22 mm, and the space occupied by each weft yarn = 2.54 / 76=0.32 mm, combined with the warp and weft yarn fineness and the actual measurement value, the corresponding space diameter is 0.25,0.25 value, if the buckling wave problem of the warp and weft yarn is not considered in each cycle unit, the smallest surface is invisible blank yarn The line lengths are: twill 2 / 1: twill warp=0.25, twill weft=2*0.25=0.5; the data of the blank section is automatically built into database X for later call and correction. According to the data of database X, the customer pattern picture is divided , through digital printing and jet printing, to obtain pattern patter...

Embodiment 3

[0045] In this embodiment, a method for obtaining the length of the blank segment covered by warp and weft yarns of the fabric, the steps are:

[0046] Obtain the basic data of the fabric required by the customer via email JT / C 65 / 35 45*45 110*76 47"8 / 3 satin; the space width occupied by each warp yarn=2.54 / 110=0.22mm, the space width occupied by each weft yarn= 2.54 / 76=0.32 mm, combined with the warp and weft yarn fineness and the actual measurement value, the corresponding space diameter is 0.25,0.25 value, if the buckling wave problem of the warp and weft yarn is not considered in each cycle unit, the smallest surface is invisible blank The yarn lengths are: satin weave 8 / 3: satin weave yarn=0.25, satin weft yarn=7*0.25=1.75; the obtained blank section data is automatically constructed into database X for later calling and correction. According to the data of database X , Divide the picture of the customer's pattern, and print it through digital printing to obtain a pattern...

Abstract

The invention provides a method for acquiring and using lengths of warp and weft mutually-covered blank sections of fabric and solves the problem that a digital printing technology cannot be applied to traditional yarn-dyed weaving all the time due to technology restrict. When the technology is applied to the digital printing technology of yarn dyed fabric, yarn is not required to be dyed in advance, and printing is performed on a loom during weaving; the covered sections are invisible on the surface of the fabric, and printing can be omitted. According to the technology, accurate area location of blank warp can be provided, the minimum printing area demand can be provided, so that the use amount of ink is reduced to be minimum, and economic benefit of an enterprise is increased; consumption of drying thermal energy is reduced while the use amount of ink is reduced. The same technology can be applied to knitted yarn-dyed fabric, and calculation is performed according to conditions of emerging segmental arc length and dry section length of a knitted fabric coil.

Description

technical field [0001] The invention relates to the field of textile printing and dyeing clothing, in particular to the field of digital printing, in particular to a method for obtaining the length of a blank section covered by warp and weft yarns of a fabric and its application. 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 presenta...
