The object of the present invention is achieved like this.

Designing the color that desire is used, choose materials and staining bath, the thing of preparing to go into to dye of going into to dye is soaked in water, and hanging a period of time, the versicolor dyestuff that will prepare again is according to the ratio of design needs, dissolve separately or comprehensively dissolve, divide successively by the time according to the design needs, repeatedly throw in versicolor dyestuff, go into to dye in the branch ratio of dying, in the dye bath process, carry out dye bath by the pre-designed scope of fluctuating.

Dividing the proportion dye is into dying 5%～95% of thing length, goes into to dye the scope that thing fluctuates and add 1cm to going into to dye the thing total length for going into the ratio of dying in dye bath.

Utilize colouring method provided by the invention, can reach such effect, being exactly no matter you will make into yarn that dyes and fabric reaches several color effects, all is to finish in one-time process.This with need repeatedly the technology known colouring method that just can finish multiple colors staining effect compare, must bring save time, laborsaving, reduce production costs, energy savings, and the Color coordinating and unifying.Simultaneously this process application scope is wide, is that the yarn and the knitted fabric and textile of raw material is all suitable to cotton, fiber crops, silk, wool, chemical fibre etc., and various corresponding dyestuffs also all are suitable for.

Further introduce the present invention below by drawings and Examples.

Accompanying drawing 1 is an artwork of the present invention;

Accompanying drawing 2 is the Color figure of embodiment 1;

Accompanying drawing 3 is the Color figure of embodiment 2;

Accompanying drawing 4 is the Color figure of embodiment 3.

Introduce technical process of the present invention below in conjunction with drawings and Examples.

Embodiment 1; Select 500 gram pure wool colour prime white reeled yarns for use, select neutral-bath dyeing for use, yellow 2 grams of ACID DYES, red 4 grams, blue look 4 grams dye with the long 30% ratio branch of reeled yarn.

Reeled yarn is soaked, and be advisable to soak into.Hanging is about 40 minutes, as the I among Fig. 1 then.2 Crane look dyestuffs are fully dissolved separately, and red being incorporated into fully with 2 remaining Crane look dyestuffs of 2 grams are yellow, 4 grams dissolved.Staining bath is unsuitable excessive, and in the present embodiment, the staining bath area is advisable with 35cm * 45cm.The water level Gao Weifen ratio of dying adds 20cm, between A-A line among the figure and B-B line.Beginning is dyed 65 ℃ of temperature, and the 2 Crane look dyestuffs that will dissolve earlier drop in the staining bath, fully stirs evenly, and the reeled yarn of hanging is gone into to dye in the length that 30% ratio adds 10cm, as the II among Fig. 1.Go into to dye and reeled yarn was mentioned in 1 minute,, go into to dye in 30% ratio again, as the III among Fig. 1 with the synthetic dyestuffs input.The III of II from Fig. 1 in Fig. 1, water temperature should rise to 100 ℃ in 45 minutes, in this process, add ammonium sulfate or the ammonium acetate of body lotion amount 2-5% in the dye bath.After water temperature reached 100 ℃, the continuous time of dying was 20 minutes, as the IV among Fig. 1, dyes effect on increasing, can add concentration at last and be 30% acetic acid, its quantity is the 1-2% of staining bath body lotion amount, carries out fixation, fixation 10 minutes, as the V among Fig. 1, reeled yarn is reduced 6cm, dyed five minutes, as the VI among Fig. 1.Dry then or dry, as the VII among Fig. 1.Reeled yarn is five kinds of colors after finishing, as accompanying drawing 2.In accompanying drawing 2, foot 30% is black, and 6cm is Dark grey on it, and up 3cm is blue grey again, and then, 2cm is pale blue, and remainder is a colour prime white.
