Problems solved by technology

The disadvantage of this method is that the exhaustion rate and half-dyeing time of testing dyes on silk fabrics are relatively large; the calculation of the IOB value of dyes must know the structure of the dyes, and the structural dyes of a large number of dyes currently used have not been published by the dyestuff manufacturers, so it is impossible Calculate its IOB value
Therefore, the above method is greatly limited in practical use.
In addition, there is no report on other methods of selecting dyestuffs for one-bath multi-color tie-dyeing of real silk

Embodiment 1

[0021] The selected dyes in this embodiment are: reactive violet X-2R and weakly acidic fruit green 3GM.

[0022] Fabric dyeing: Take 9 pieces of silk fabrics cut into 10cm×10cm size, stack them neatly, sandwich them between two splints of the same shape and size, which are not easy to deform under dyeing conditions, and do not absorb dyes, and fix them with a constant clamping force . Put the clamped silk fabric into the dye bath for dyeing. The fixed dyeing conditions are: dye dosage 5% owf, bath ratio: 1:20, dyeing temperature: 95°C, pH value 4, dyeing time 30min. Take it out after dyeing, remove the splint, dry the fabric, and perform image processing after flattening.

[0023] See attached figure 1 , which is a workflow diagram of the image processing steps in this embodiment. In this embodiment, a digital camera is used to take pictures of the fabric obtained by clamp dyeing under the same conditions, and the initial images are collected. Use image processing techno...

Abstract

The invention relates to an image recognition based selection method of dyes for tie-dyeing of silk fabrics, belonging to the technical field of special textile dyeing processing. Samples are obtained by adopting a clamp dyeing process, processing and grade statistics are carried out on color images obtained by dyeing the samples, and the diffusion and permeation degrees of the dyes on the fabrics during clamp dyeing are quantitatively described according to the percentages of the fabric areas in different grades of regions: if the dyes occupy more areas in low grade regions, the diffusion and permeation degrees of the dyes on the fabrics are higher, and if the dyes occupy more areas in high grade regions, the diffusion and permeation degrees of the dyes on the fabrics are lower; therefore the one-bath multi-color effects can be obtained by randomly selecting two kinds of dyes with bigger difference of coloration area parameters to undergo color matching to be used for tie-dyeing of the silk fabrics. The method is simple and intuitive to operate, is convenient and fast, has good dyeing effects, and is suitable for industrial production.

Description

technical field [0001] The invention relates to a method for selecting dyes for tie-dyeing silk fabrics, in particular to a method for selecting dyes for one-bath multi-color tie-dyeing silk fabrics based on image recognition, and belongs to the technical field of special dyeing of textiles. Background technique [0002] Tie-dyeing is a dyeing technique that uses various mechanical anti-dyeing methods such as sewing, binding, and bandaging to prevent dyes from being dyed locally in accordance with the requirements of pattern design, so that natural patterns or hazy similar patterns appear on the anti-dyed parts. Tie-dyeing integrates modern dyeing and finishing technology and art, and has the characteristics of combining national tradition and the atmosphere of the times. The unique color halo texture effect of tie-dye products and the obvious artistic effect of different reliefs cannot be imitated by general mechanical printing products. Generally speaking, during the dyei...
