Definitions

• This invention relates to an ink jet dyeing method for dyeing various designs clearly and effectively on a surface of a woven, knit or non-woven cloth of various fibers by ink jetting.
• ink jet dyeing method for dyeing various designs effectively on the surface of a woven, knit or non-woven cloth by ink jetting, which was developed for printing on paper, is disclosed in, for example, Japanese Patent Laid-Open Publication No. Sho 54-18957.
• Various developments for realizing the ink jet method in the field of dyeing are going on.
• a method of preventing the spread of dye ink by applying an anti-spread agent, which adheres to dye and retains it, onto the cloth surface before dyeing is disclosed in, for example, Japanese Patent Publication No. Sho 63-31594.
• at least one kind of compound selected from the group consisting of a water-soluble high polymer, a water-soluble salt and water-soluble inorganic minute particles, which are substantially unable to adhere to dye and are able to retain the dye is attached to the cloth surface by 1 to 50% in the preparation process, then dye ink is given by ink jetting, whereupon the compound or compounds is heated to fix and is then washed away.
• an ink jet dyeing method for dyeing a cloth of fibers by ink jetting, wherein a highly water-absorbing high polymer is applied to the cloth before ink jetting.
• the ink jet method to be used in this invention should by no means be limited to a particular form.
• the typical conventional form is exemplified by a electrostatic attraction method in which a typical form, a strong electric field is given between a nozzle and an accelerating electrode forwards of the nozzle and ink particles are jetted from the nozzle according to an information signal, an ultrasonic oscillation method in which ink to be supplied under high pressure is sprayed in minute particles from a nozzle, which is vibrated by a crystal vibrator, according to an information signal, and a piezo compoment method in which ink is sprayed from a nozzle by giving an electrical signal to a piezo component to apply pressure to ink.
• Dye ink is prepared by adding, to the dye and liquid, various kinds of additives such as an anti-dry agent of, for example, glycol group, a dye solvent, a characteristic adjust agent, an antiseptic, a sterilizer and a chelating agent.
• an anti-dry agent of, for example, glycol group, a dye solvent, a characteristic adjust agent, an antiseptic, a sterilizer and a chelating agent.
• An anti-spread agent to be used in this invention is a high polymer compound which is insoluble with water and absorbs much water, i.e. a high polymer substance called "high water-absorbing resin".
• the high water-absorbing resin is exemplified by vinyl alcohol acrylate, sodium acrylate copolymer, dextrin-acrylate graft copolymer cure and cured polyacrylate salt.
• Application of the anti-spread agent to the cloth may be performed by a suitable means, such as panting, soaking or spraying.
• the individual highly absorbing water-insoluble high polymer compounds has such a characteristic as to instantaneously absorb water tens to thousands times the own weight to gel. Accordingly, if the highly absorbing high polymer compound is applied to the cloth previously, the dye ink will be temporarily absorbed and held by this highly absorbing high polymer compound, and even a definitely small amount of highly absorbing high polymer compound applied will suffice to achieve the original purpose. When the dye is fixed, the water temporarily absorbed by the highly absorbing high polymer compound will be vapored and the dye held by the same compound will be combined with the fibers to develop a color while the compound also will be attached to the cloth surface to fix.
• the texture of the cloth is kept free from being impaired.
• the compound existing on the cloth surface does not allow raindrops on the front surface to pass to the back surface.
• Three water solutions were prepared each containing tens grams per liter of each of Sumika Gel SP510 (Example 1, colloidal solution; vinyl alcohol acrylate copolymer produced by Sumitomo Chemical Co., Ltd.), Arabia rubber (Comparative Example 1) and montmorillonite (Comparative Example 2).
• a cloth woven of processed threads made from polyester fibers was soaked in each of the three solutions and was squeezed by 60% using a pad, whereupon the cloth was dried at 100°C for ten minutes. The resulting cloth was dyed under the following conditions.
• Dianix Black FG-P disersion dye produced by Mitsubishi Chemical-Hechist Co., Ltd.
• polyethylene glycol average molecular weight: 400
• glycerine 15% by weight of glycerine and 60% by weight of ion-exchange water
• the printed cloth was treated to develop color under the following conditions and was then treated by reduction washing, whereupon washing by water, neutralization, washing by water and drying were performed.
• Table 1 shows that no spread came out in this invention while spread was found in Comparative Examples, and that the L value in this invention was smaller than those in Comparative Examples.
• Three water solutions were prepared each containing tens grams per liter of each of Sanwet IM-1000MPS (Example 2, dextrin-acrylate salt graft copolymer cure produced by Sanyo Chemical Co., Ltd.), Arabia rubber (Comparative Example 3) and montmorillonite (Comparative Example 4).
• a cloth woven of processed threads cloth woven of viscose rayon threads made from cellulose fibers was soaked in each of the three solutions and was squeezed by 60% using a pad, whereupon the cloth was dried at 100°C for ten minutes. The resulting cloth was dyed under the following conditions.
• the printed cloth was treated to develop color by exposed to saturated vapor at 100°C for 15 minutes, whereupon washing by water, neutralization by an acetic solution (0.1 grams per liter) and washing by hot water at 90°C for 10 minutes, and finally washing by water and drying were performed.
• Table 2 also shows that in this invention it is possible to prevent spread of dye ink better than in Comparative Examples.
