Description

Printing Method of Natural Fabric Clothes Using the Digital Textile Printer

The present invention relates to a method of transferring a cloth cloth fabric using a digital textile printer of the present invention. Specifically, a pattern is printed on a wax-coated base layer with a reactive dye using a digital textile printer and then transferred to a natural fiber garment or a sample fabric using the same. A method of transferring from a device.

In general, the transfer or printing of fibers means that the fabric or clothing is partially colored so that a pattern appears. Direct dyes and reactive dyes are used for printing fabrics. Direct dye has the advantage that the process is simple because it has a property of dyeing directly by adding the preparation to the fibers such as cotton, silk, etc. without embedding. However, direct dye dyes have the disadvantage of low daylight, flushing and laundry fastnesses. On the other hand, the printing method of the fiber using the reactive dye is combined and dyed by the hydroxyl group (-OH) of the fiber by a chemical reaction, but has the advantage of high fastness, but the dyeing process is difficult and the amount of waste water generated a large amount of waste water due to the environment There is a disadvantage that there is a fear of contamination.

In general, a direct roller printing method is used as a method of transferring a fabric using a reactive dye, and in the case of roller printing, there is a problem in that the economic efficiency is low because a manufacturer actually stores a large amount of individual design supplies in an up-to-date state. As an alternative, Korean Patent Laid-Open Publication No. 1989-0701834 proposes a method of forming a predetermined transfer pattern on a pattern transfer body web and contacting the fabric to print.

However, when the transfer pattern is formed, the pattern of the transfer web is printed on the actual fabric, but the pattern is not printed clearly or it is difficult to form a detailed design.

General printing maintains the resolution of 90 ~ 120 mesh, but when using digital textile printer, it shows the high resolution of 200 ~ 1200 mesh or more, so it can express the same resolution as the photograph.

The present invention provides a method of printing a garment or sample of a dye made of natural fibers using a digital textile printer and a wax coating base layer.

1 illustrates a transfer process of the present invention.

The transfer process of the present invention comprises the steps of preparing a wax-coated base layer (S11), a step of preparing a reactive dye (S12), the step of printing a pattern on the wax-coated base layer after the injection of the reactive dye digital textile printer (S13), After fixing the pre-treated natural fiber fabric or clothing in a fixed frame (S14), the low temperature aging or high temperature aging step (S15), washing and drying step (S16).

Step (S11) of manufacturing a wax coating base layer is prepared by coating a wax on a base layer made of paper or the like and coating it once more with a coating agent in order to prevent bleeding of the dye.

The wax is used by mixing the microcrystalline wax (Microcrystalline wax) with a surfactant and then melted. Microcrystalline wax, also called microwax, is a wax dewaxed and degreased by solvent extraction from high viscosity lubricated distillate and deasphalted oil from residue, and is composed of branched saturated hydrocarbons. It takes the form of small crystals, both amorphous and amorphous. Microcrystalline wax is composed mainly of branched saturated hydrocarbon with 40-60 carbohydrates, and contains small amounts of normal paraffin, naphthenes and aromatics, and has a molecular weight of 550-850.

The surfactant is added to the microcrystalline wax in an amount of 1 to 10% by weight based on the total weight of the wax composition, and then melted at 100 to 150 ° C. to prepare a wax composition, which is then gravure coated on the base layer.

The surfactant may be an anionic surfactant. Anionic surfactants include sodium dodecylsulfate, sodium lauryl sulfate, sodium dodecyl benzene sulfonate, and dodecyl allyl. Sodium dodecyl allyl sulfosuccinate, disodium ethoxylated alcohol half ester of sulfosuccinis acid, sodium dioctyl sulfosuccinate, proprietary sulfosuccinate blend ), Acetylene oxide ethyl alcohol (acetylene oxide ethylealcohol) may be used one or more. In the present invention, it is particularly preferred to use proprietary sulfosuccinate blend or acetylene oxide ethyl alcohol alone or in combination. By adding 1 to 10% by weight of the surfactant to the total weight of the wax composition, the microcrystalline wax in powder form is uniformly melted and a liquid composition having a hydrophilic group is prepared.

The prepared liquid wax composition is applied to the base layer by a gravure coating method. In gravure coating, it is preferable to coat the wax composition while heating to 100 to 130 ° C., in order to uniformly coat the base layer. The wax layer to be coated is preferably a thickness of 20 ~ 100㎛.

Alternatively, instead of a wax layer, an acrylic polymer may be gravure coated to form an acrylic polymer layer. In the case of printing the pattern on the wax coating base layer at a high temperature, it is more preferable to coat with an acrylic polymer instead of the wax layer. Since the microcrystalline wax has a melting point of 65 to 80 ° C., the microcrystalline wax melts when transferred at a high temperature above the melting point. Therefore, in the case of high temperature transfer, it is preferable to coat with an acrylic polymer instead of the microcrystal wax.

Next, the coating composition is coated on the wax layer to which the wax composition is applied. The coating composition is a liquid composition prepared by stirring 10-20% by weight of ethylated corn starch, 1-10% by weight of polyvinyl alcohol, 1-10% by weight of alumina, and 1-10% by weight of silica with water. Coating using the coating composition is carried out 2 to 3 times in a gravure coating method to form a thickness of 20 ~ 100㎛. In the present invention, by coating the coating on the surface of the wax layer, the dye is fixed to the surface of the base layer in a fixed form without dye penetrating into the base layer during pattern formation, thereby preventing the dye from spreading on the base layer. This allows the pattern of the base layer to be transferred to the to-be-contaminated material without changing its shape in the transfer process.

Next, desalting and purifying the reactive dye to prepare (S12), the reactive dye used in the present invention can be used a dye that can be applied to any method, but using a dye that can be applied to a medium or low reactive dyeing method It is desirable to. The reactive dye may have any reactor, preferably at least two reactors. A vinyl sulfone type dye may be used as the reactive dye that satisfies the above conditions. Examples of the dye include a remazol type dye or a cibacron FN or Sibacron C dye. In the present invention, both dyes capable of low temperature fixing can be used.

In general, when a reactive dye is used in a digital textile printer, there is a problem in that the nozzle of the printer is clogged due to a salt component such as sulfate present in the reactive dye. In order to solve this problem, in the present invention, the reactive dye is dissolved at a temperature of about 90 ° C. and then a water-miscible organic compound is added to remove the salt component. The residual salt component is removed using a conventional filtering process using a filter, and the usable filter preferably has a pore size of 1 to 10 nm. The purified dye has a particle size of 0.2 μm and a salt concentration of 5 ppm or less.

To the salt-free dye, 0.05-0.2 wt% metal ion disintegrant, 0.5-2.0 wt% dispersant, 10-30 wt% wetting agent, and 0.01-0.5 wt% preservative were added again to the salt solution. Filtration was carried out, and then stored in a dye reservoir for 3 days at 5 ℃. The humectant is ethylene glycol monomethyl ether, ethylene glycol monoethyl ether, propylene glycol monomethyl ether, diethylene glycol monomethyl ether, ethylene glycol monoethyl ether, ethanol, propanol, butanol, hexanol, cyclohexanol, ethylene glycol , Diethylene glycol, butyl glycol, polyethylene glycol and glycerin is preferably used alone or in combination of one to three selected from the group consisting of. Three days after storage, the dye is filtered using a micro filter to remove impurities once more and then the dye is injected into a digital textile printer.

Next, a desired pattern is formed on the wax-coated base layer using a digital textile printer in which reactive dye is injected (S13). When the pattern is formed on the base layer, it is transferred to the tainted material using the transfer device (S14).

It is installed so as to be wound around the second upper base layer roll 22 and the second lower base layer roll 24. As a result, the wax coating base layer 25 is fixed by the upper base layer rolls 21 and 22 and the lower base layer rolls 23 and 24 to form the wax coating top base layer 25 and the wax coating bottom base layer 25. In order to facilitate the compression and transfer of the wax coating base layer 25 and the chlorine, the silicon pad 29 having a thickness of 5 to 10 mm is fixed to the adhesive surfaces of the upper press 26 and the lower press 27. On both ends of the upper press 26 and the lower press 27 is attached a detection sensor 28 for detecting whether or not to insert the blood, when the blood press is inserted the upper press 26 and the lower press 27 Operate up and down to be in close contact with each other and press the pneumatic or hydraulic pressure of about 2 ~ 200bar to squeeze the chlorine. The pressure applied to the press can be adjusted according to the type and thickness of the blood. At this time, the upper and lower surfaces of the blood to be transferred to the blood to the pattern printed on the wax-coated base layer.

In the present invention, a hot wire (not shown) may be mounted between the upper press 26 and the lower press 27 and the silicon pad 29 to enable high temperature transfer of 100 to 200 ° C. The high temperature transfer can be selected according to the type of dye and the material of the cloth fabric cloth.

The dye may be a fabric or a garment made of natural fibers, which will be described below when the garment is a dye. After the immersion is immersed in the alkaline dipping liquid before the transfer step, it is dehydrated at a high speed so that the pick-up rate is 30 to 60%, preferably 50%, and then fixed to the chlorine fixing frame and introduced into the transfer device 20. . The alkaline dipping liquid is a mixture of caustic soda (NaOH), sodium silicate (Sodium Silicate: NaOnSiO ₂ mH ₂ O), anhydrous forget-me-not and a penetrant.
