Description

Transfer printing of polyester fiber materials

The present invention relates to a transfer printing method for a polyester fiber material using a non-sublimation type disperse dye.

As a method for printing a pattern with a disperse dye on a polyester fiber material, screen printing using a disperse dye color paste, roller printing, and rotary screen printing are known and practiced industrially. However, these plate-making printing methods are inferior in design expressiveness and require plate-making, making them unsuitable for small lots and short delivery times. It is necessary to make surplus color paste in addition to using a large amount of color paste. Therefore, there are many problems such as heavy drainage load, complicated work process, subtle coloration and mold matching, skill required, and high incidence of defective products.

Patent Document 1, Patent Document 2, Patent Document 3, Patent Document 4 and the like disclose sublimation transfer methods using printing paper obtained by ink-jet printing an oil-based ink or water-based ink containing an E type sublimation dye on sublimation transfer printing paper. And is industrially implemented. When sublimation transfer printing is performed on polyester fibers by this sublimation transfer method, Patent Document 4 discloses a method of increasing the residence time at low temperature (140 ° C.) (5 minutes), but this method has a problem in productivity. Therefore, heat treatment is usually performed at 190 to 200 ° C. for 30 seconds to 1 minute.

However, since these dye sublimation transfer methods require uniform dyeing and reproducibility to polyester fibers, there is a problem that dyes having similar sublimation properties are required for each color, and usable dyes are limited. . In addition, sublimation dyes are small molecular weight dyes, and have a problem that they are easily moved and diffused by heat and jump out of the fibers into the air to contaminate other fibers and white spots. For example, when the transfer temperature is high, the dye once dyed jumps out of the fiber material (fabric), so there is a problem that the pattern is blurred and the transfer device and the environment are contaminated. Therefore, the transfer temperature is generally processed at a temperature of 200 ° C. or lower. Furthermore, the heat fastness of products dyed with sublimation dyes is extremely low, and the hue and other fastnesses are also limited, making them unsuitable for apparel as products to be processed. Further, there is a problem that the used paper used in the sublimation transfer method cannot be used for recycled paper due to hydrangea spots.

On the other hand, the method of transfer printing at 190 to 200 ° C. for 30 seconds to 1 minute using a transfer paper printed with a non-sublimation disperse dye ink on a known sublimation transfer printing paper has poor color developability and has practical value. There is no. That is, even when known sublimation transfer conditions are applied to a non-sublimation type disperse dye, good color developability cannot be obtained.

As a method for solving these problems, Patent Documents 5 and 6 disclose that an ink receiving layer is coated on a release paper and dried, and then printed on the ink receiving layer with a disperse dye. A method of sequentially performing dye transfer to a fiber material, release of release paper, and fixing of a dye by steaming is disclosed. However, this method cannot transfer 100% of the ink receiving layer if the cost of the release paper (transfer base paper) is high, the humidity of the factory where the transfer is performed, and the storage conditions of the transfer textiles are inappropriate. There are problems such as generation of non-defective products, difficulty in recycling paper, and a large number of processes.

In Patent Document 7, a water-soluble synthetic binder, a natural glue, and a mixed glue solution, to which an auxiliary agent is added, are added to an inexpensive commercially available paper, and the temporary adhesive force to the fiber material is increased by heating and pressing. Coating and drying to form an ink-receptive layer and adhesive layer, and then coloring the transfer-printed paper obtained by printing the disperse dye ink on the transfer-printed paper obtained in this way (paper printing method) ) Is disclosed. This method is an excellent processing method in that no pre-treatment of the fiber material is necessary, but there is a problem that the number of steps is large because a crimping step, a coloring step (dry heat treatment or steaming), a soaping step, etc. are necessary. .

In addition, a direct method is also known in which disperse dye ink is printed with an inkjet printer on a dried fabric (fiber material) after applying a paste to the fiber material (pretreatment). However, this method requires a pretreatment process, a printing process, a steaming process, and a soaping process of the fiber material, and has a large number of processes and a drainage load, so that there is a problem in economic efficiency and quality stability.

In the present specification and claims, terms relating to paper used for printing may be used in the following meaning.
(1) Base paper: Paper (or film) before applying glue
(2) Transfer printing paper: base paper coated with paste (3) Transfer printing paper: transfer printing paper to which dye ink is applied

Thus, the dyes that can be used are limited to known sublimation transfer methods, methods of applying known sublimation transfer conditions to non-sublimation type disperse dyes, known dry transfer methods, direct methods, and other known printing methods. Problems, product quality problems such as fastness, hue / color development, stability of quality, economic problems such as many processes, high raw material costs, contaminating other fibers and the environment, Problems with the environment (ecology) such as heavy drainage load have been pointed out.

I. Disperse Brown 1, 4, 9, 13, 19, 24, 25 etc. Black can be produced by blending the three primary colors + α of these fast S-type dyes. Specific examples of the E type sublimation dyes include the dyes described in claim 9 of JP2011-21133A, but not limited to the sublimation fastness, and the light fastness. There are many dyes with generally low fastness.

The non-sublimation type disperse dye is converted into an ink so that it can be used as an inkjet ink, a gravure ink, a flexo ink or the like. After being converted to ink, ink is printed (printed) on the transfer textile sheet by inkjet printing, gravure printing, flexographic printing, or the like to produce transfer textile paper. The dye content (chromogen) in the ink is preferably 1 to 15% by mass depending on the color density. The ink to be used can be oil-based ink, but it is desirable to use water-based ink in consideration of occupational safety and health, environmental problems, handling of dangerous goods, and economy.

In the case of inkjet inks, dyes atomized to have an average particle size of 0.05 to 0.2 μm are preferably used. Atomization can be carried out by a known method using a bead mill or the like in the presence of a dispersant. The ink used in the ink jet printer is preferably a finely divided dye, a dispersion stabilizer, a drying inhibitor, and surface tension adjustment. Add and mix agents, viscosity modifiers, pH adjusters, antiseptics, antifungal agents, sequestering agents, antifoaming agents, deaerators, dispersants, etc. Filtered and degassed with a membrane filter. If the average particle size is too small, reaggregation of the particles tends to occur. On the other hand, if the average particle size is too large, the problem of clogging the nozzles of the ink jet printer tends to occur.

In the case of gravure printing ink (gravure ink) or flexographic printing ink (flexo ink), a dye finely atomized to an average particle size of 0.2 to 10 μm is preferably used together with a dispersant. Whether the average particle size is too small or too large, printability and color developability tend to be poor.

In the case of gravure printing or flexographic printing, ink in which the atomized dye is mixed and dispersed in a viscous aqueous solution containing a thickener and the viscosity is adjusted to about 30 to 500 mPa · s can be used. Dispersing agents that can be used include naphthalene sulfonic acid formalin condensate, methyl naphthalene sulfonic acid formalin condensate, lignin sulfonic acid, olfin PD-003, olfin PD-001, olphin PD-002W, olphin PD-004, olphin PD-005. , Olfin PD-201, Olfin PD-301, and the like. More specific examples of gravure printing ink, such as Metrose 65SH / 400 (manufactured by Shin-Etsu Chemical), Metrose 65SH / 4000 (manufactured by Shin-Etsu Chemical), and Poval AP-17 (manufactured by Nihon Vinegar & Poval) Non-sublimation disperse dye of S or SE type, which is hydrolyzed PVA as a thickener and atomized to an average particle size of 0.5 to 10 μm, is contained in an amount of 1 to 15% by mass in terms of chromogen, and printing ink And an ink having a viscosity of 30 to 500 mPa · s.

[Transfer printing process]
The transfer printing paper obtained as described above and the polyester fiber material (fabric) are overlapped, and the dye is transferred to the fiber material by pressurization and heating, whereby the transfer printing of the present invention is performed. In general, the heating temperature (transfer temperature) and the pressurizing pressure (transfer pressure) are in the range of 150 to 250 ° C. and 0.01 MPa or more, respectively, preferably 200 to 230 ° C. and 0, respectively. The range is from 0.02 to 4 MPa. When the temperature or pressure exceeds the upper limit, the texture of the product tends to be inferior. On the other hand, when the temperature or pressure is less than the lower limit, the color developability tends to be insufficient.

The pressurizing / heating time (processing time, transfer time) is usually in the range of 1 second to 10 minutes. However, the higher the temperature and pressure, the better the color developability and the shorter the processing time. In order to improve the property, the higher the temperature and the higher the pressure, the better. For example, when the transfer temperature is 220 ° C. and the transfer pressure is 0.05 MPa, good color developability can be obtained even with a processing time of 30 seconds.

[Polyester fiber material]

The present invention will be described in more detail with reference to the following examples. However, the scope of the present invention is not limited to these examples. In the examples, unless otherwise specified, “part” means “part by mass” and “%” means “% by mass”. In Examples 1 to 7 and Comparative Examples 1 to 4, the dyeing power after transfer printing (coloring property of the fiber material (fabric)) and leveling property were determined according to the following criteria.
○: Good color quality (dyeing power), levelness and fastness of the fiber material and good quality.
(Triangle | delta): The coloring property (dyeing power) and leveling property of a fiber material are a little inferior, and a quality is bad.
X: The coloring property (dyeing power) and leveling property of the fiber material are clearly poor and the quality is clearly poor.
