The preparation method of colour brocade
The invention belongs to the silk goods preparation method, particularly have a preparation method of silk goods of multicolour pattern.
The color of traditional colour brocade all is that warp, the tram line that relies on different colours shows with floating long form, and its color is more simple, to embody the solid colour of silk thread, normally wants to weave the grain pattern of what color, with regard to the silk thread with what color.If will show more silk weaving color content, just must use polychrome warp, parallel to interweave, give birth to the product that the silk mill makes as most typical by Hangzhou Dou Jin, adopted 13 shuttle, the parallel of 13 kinds of different colours is inweaved in the pattern, so that the picture-weaving in silk picture obtains more rich color effect.But this mode is in artistic conception, can only produce the variation that interweaves of tens of kinds of structures at most, embody tens of kinds of color change (color is the external manifestation of institutional framework usually), therefore in colour phhotograpy, color ink jet printed technology and advertising, press highly developed today, the color limitation that traditional colour brocade art is shown, become the principal element that traditional picture-weaving in silk art can't adapt to the modern life and society need, if solution is bad, this outstanding national tradition technology of colour brocade will be gone no further in our generation and be forfeited even.
Moreover, the production technology of traditional colour brocade is also very loaded down with trivial details, and it is all very high to equipment and employee's requirement.For example produce and as 13 shuttle boxs, to design just pretty troublesome additionally acquiring complicated multi-shuttle box device on the loom usually in operation and traverse.The specification requirement to the spinner again is also quite high.Elsewhere, the increase of shuttle box causes the reduction of the speed of a motor vehicle, and production efficiency is obviously descended, and manufacturing cost is increased substantially.
The objective of the invention is to provides easy to make, quick for overcoming the defective of prior art, the preparation method of a kind of colour brocade that colour developing is abundant, picture is vivid.
Technology of the present invention solves its scheme step: (1) card is made, and (2) loom is prepared, (3) looming weaving;
(1), card is made
1. the target image that will treat the weaving brocade reads in computer, enters scanning imaging system;
2. adjust scan image, set sweep parameter;
3. the image that reads in is made picture and modify, remove the unclean part of picture;
4. bright, the blindstory of adjusting picture distribute the merger color;
Its special character is: after connecing (1)-4.,
5. all colors are returned to be divided into the color scheme of forming with red, yellow, blue, black, white 5 kinds of mixing colors, import the card tissue successively;
6. the card file of making in the computer is admitted to disk, finishes card and make;
(2), loom is prepared
1. the silk thread of red, yellow, blue, black, white 5 kinds of colors is done a kind of through, parallel with silk thread of the same colour wherein, all the other look silk threads are made the another kind through, parallel, carry out warping, pirn winding process;
2. according to description, adjust the knitting technology parameter;
(3), looming weaving
The card of made is disposed at loom, starts loom and weave colour brocade.
Card of the present invention is made, and carries out on computers.
Described target image is meant the original image that picture-weaving in silk contrasts.Describedly the image that reads in is made picture modify and to be meant with the CAD image processing system picture is modified.
Described all colors are returned is divided into color scheme that 5 kinds of mixing colors form and is meant with the PORG tissue processing system and returns branch.
The present invention can adjust the knitting technology parameter according to description in the loom preparatory stage, and description is meant parameters such as the size, density, silk thread kind of purpose picture-weaving in silk thing.
The present invention is different from traditional colour brocade method.Method of the present invention, for purpose picture-weaving in silk thing, no matter to show the how many kinds of colour, all need only and use red, yellow, blue, black, white five kinds of look silks, form warp, parallel, its middle longitude and parallel exchange, the result is the same, in addition, can also increase a certain tendentious special-purpose look silk as the modern art of printing.
Colour developing principle of the present invention, be by with described look silk, adopt different institutional framework braidings to change, make silk thread of all kinds in different permutation and combination, show different covering and floating long,, form thousands of color effects to reach thousands of variation combinations, as several pigment collocation tonings, it is such thousands of kinds of colors to occur.Common pigment collocation toning of all kinds has randomness.When strictness quantitatively and increase progressively and pigment is mixed in the toning of successively decreasing, then can produce the color of a series of gradual changes, it is collected in together, just can be made into a kind of " color harmony manual ", can satisfy various colour developing needs.Compete into Co., Ltd of firm by Hong Kong and publish, issue, international uniform book number 962-7561-13-4 " ADC four look color harmony manuals " are a kind of like this handbooks, have collected a large amount of by mixing " color lump " that pigment quantitatively changes the color gradient of generation in the handbook.The present invention can quantitatively manifest covering and floating length by employing look silk permutation and combination, so just can be with reference to described color harmony manual, and allotment is knitted and is made picture and the appropriate color brocade of target image.
The present invention is owing to adopt the Computer Image Processing method, the color of target image returned be divided into red, yellow, blue, black, the color scheme that white 5 kinds of mixing colors are formed, input card tissue, make card, again this card is disposed at loom, and with the silk thread of described 5 kinds of colors, on loom, change and interweave, present the different covering of look silk and floating long, thus, as mixing colours with described 5 kinds of pigment collocation, on the picture-weaving in silk picture, can produce thousands of allotment colors, the combination of all these colors just obtains and the quite similar picture-weaving in silk image true to nature of target image, and its similar degree true to nature is higher than traditional colour brocade that only has tens of kinds of color change far away.Owing to only need adopting 5 kinds of look silks, the present invention knits (can add certain tendentiousness look silk when needing again) again, so picture-weaving in silk is easy to make, quick, easy and simple to handle, and the production efficiency height.
Further specify technical scheme of the present invention with example of making below.
One 5 inches common color portrait photos are made into 20.8 centimetres of fabric widths, high 28 centimetres colored silk woven picture picture.Warp (white) 2400 is used in this portrait design, is the mulberry silk of 2/20/22 DENIER, and totally 1120 * 4 in parallel (being respectively red, yellow, blue, black) is the mulberry silk of 2/20/22 DENIER.Operating procedure is:
1, photochrome is put into the color scanner that links to each other with computer and scanned, do preview earlier.
2, look the situation of preview, according to making needs parameter adjustment is set, see that the image that reads in is decided to be in scanning accuracy under the situation of 290 dpi from the scanning preview, the picture element of its warp-wise (vertically) is 2485, and the picture element of broadwise (laterally) is 4140; Should adjust the color lightness of scanning in addition, formally scan then.
3, the image after will scanning is deposited, and withdraws from scanning imaging system.
4, enter the computer silk weaving jacquard weave design (CAD) system of specialty, carry out image and handle.Be mainly 1. edge of image is sheared,, now it is adjusted into 2400 * 4040 picture elements, 2. remove the variegated point on the picture to guarantee picture quality.
5, image is carried out color separation.Above-mentioned image color segmentation Cheng Hong, Huang, indigo plant, black 4 width of cloth color separation original texts (also available other point-scores).
6, zoomed image specification.Above 4 width of cloth color separation original texts are compressed into 2400 * 1120 picture element specifications respectively.
7, color separated image is entered PORG (organized processing software) system, carry out card and make processing.As earlier the color separated image original text file of redness being put into the PORG system, making it redness transits to white and is divided into color range by 32 depth even transition, with its insert respectively by 31/32 red silk thread and 1/32 white silk interweave (taking on a red color) carry out the transition to the interweave tissue of (being white in color) of 1/32 red silk thread and 31/32 white silk, i.e. gradual transition from red to white, the color separation original text of other Huangs, indigo plant, black are also handled according to this method respectively.Each group parallel and warp interweave and all form card one group of simple color, that have light and shade to change like this, and every group all can supply 2400 warps and 1120 parallels interweave.
8, with above four groups of cards, the order by red, yellow, blue, black, being arranged in order (is red 1, yellow 1, blue 1, black 1, red 2, yellow 2, blue 2, black 2 ... arrangement) the colo(u)r streak picking order of card order that sets and correspondence is consistent.
9, at last the card and the relevant parameter that make are admitted to disk, use when the sub-jacquard weaving machine of powering is weaved.
10, on loom, settle warp and parallel.Totally 2400 of warps are white, arrange by 115 every centimetre to be provided with.Red, yellow, blue, the black four kinds of colo(u)r streaks of parallel use.The picking order should be with the card sequence consensus of corresponding look.Weft density is set at every centimetre 40 * 4 groups.
11, the card disk is inserted the electronic jacquard loom, start loom, just can weave desired colored silk woven picture.
