Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a printing method for efficiently forming a special pattern on a fiber assembly such as a cloth or a garment. More specifically, by using a relatively simple method, the special design required for printing products that accelerates the production of small lots of a wide variety of products, where individualization or differentiation is desired
It relates to a novel printing technology that has greatly improved productivity, and has a built-in feature that can greatly contribute to labor saving in plate making and printing processes, which are required by skilled workers. In particular, the present invention focuses on dance costumes and yukatas where novel designs are desired from the current situation where it is pointed out that economical difficulties are pointed out in enlarging the hardware related to inkjet printing applied to plateless printing. Application to apparel products such as kimono fabrics, T-shirts, sweaters, etc. is suitable, but is not substantially limited to the width of the fabric.

In addition, many of the ink jet printing related technologies generally proposed as a system similar to plateless printing, mainly include hardware such as a printer, or software such as ink, etc., and a practical range specified by a manufacturer. It is noted that the present invention has room for freely selecting and using designs or coloring materials at the discretion of the textile processing company, although there are many restrictions such as limitations on the printing process.

[0003]

2. Description of the Related Art A printing technique is one of the most widely used methods among many fiber processing techniques for dyeing a fiber structure in multiple colors and imparting a design to a fabric. Generally, the basics of printing techniques are classified as follows according to the printing method. In other words, "hand-painted Yuzen" production method, which is awarded as a representative example of high value-added processing as a fashion or luxury apparel material for advanced consumers,
Hand printing method using a screen type suitable for high-mix low-volume production as an alternative to being ranked relatively low,
Roller printing method that applies an engraving roll that is suitable for mass production but has significant difficulties in workability, and automatic that is classified into flat or rotary type that emphasizes intermediate quality with relatively medium productivity It is well known that it has been classified as a screen printing method.

After that, a transfer printing method was developed and put into practical use as a new printing technique, and in order to meet the demand for rationalization of production surrounding the printing industry, a photoelectric method, an electrostatic photography method, an electrophotographic or electrophotographic copying method, a dyeing printing method. It is also well known that various innovative printing methods such as an inkjet printing method which is linked with a spray dyeing method and an image processing system have been proposed.

[0005] However, the trend of actual demand for printed goods in the domestic textile market accompanying the improvement of the consumer's clothing life has shifted from standard clothing materials that can be satisfied with imported materials supplied at low prices to advanced consumers. The shift to the production of differentiated materials with a focus on individuality has been rapidly strengthened, and the trend of printing technology has been broadened in the related industries, with the trend toward high-grade printing similar to traditional hand-painted yuzen and hand-printing in the related industries. It is also the opinion of experts that a recognized environment is being created.

On the other hand, in the new printing method proposed thereafter, sublimation-type thermal transfer printing using a slight amount of disperse dye is mainly used for industrial purposes such as "stream", "flag" and "draft" of synthetic fiber cloth mainly composed of polyester. It is only used as an advertising medium. In addition, the inkjet system, which has been regarded as a next-generation textile printing technology, has also begun to be put into practical use as a color copy reproduced on limited, narrow paper. For practical use as a coloring technique, for example, the color density is insufficient, the penetration of the coloring component into the inside of the fabric is poor, the combination of the applied fiber material and the coloring composition is limited, and the sharpness of the pattern is poor. And so on.

[0007]

DISCLOSURE OF THE INVENTION As a result of a detailed analysis of the circumstances of the textile printing industry, the inventors of the present invention respect the needs of consumers who desire individualization, and promptly produce textile products of a large variety of small lots. In order to supply to the market, as a result of diligent research on the current countermeasures in consideration of the lack of skilled workers on the producer side, as a result of the conventional screen type hand-printing and inkjet printing, which is generally called computer printing, is applied. It is intended to establish the textile printing technology to efficiently produce a special design consisting of a pattern.

That is, a hand screen printing method capable of drawing "effect color" or a relatively large pattern,
A computer printing method capable of exerting its technical characteristics in drawing relatively detailed patterns such as repeat patterns such as "blurring" or "Edo-shoku" and "komon" and differentiating patterns such as "family crests" and "signs" The following is a summary of the pattern characteristics resulting from the combination of the above and the problems extracted in the process of promoting the rationalization of the platemaking work, especially for the latter delicate special designs.

On the same fabric, for example, a plate-printed pattern is first printed and dried, fixed, post-treated and finished, and then a plateless printed pattern is separately printed and dried, fixed, post-treated and finished. The method of synthesizing a composite pattern by using this method causes a significant morphological change in the process of wetting and drying due to fixation of plate printing, post-treatment, finishing treatment, etc. It becomes virtually impossible to align with the design to
The same applies in the opposite case. Therefore, on fabrics prepared and prepared under a sufficient production control system equivalent to ordinary printing, resin-based covering, printing, drying, fixing, post-treatment, etc., applying the pressure-sensitive adhesive required for each printing method The first step in practical use is to make the basic unit operation of the printer fully shared through plate printing and plateless printing. However, in the present invention for the purpose of imparting a pattern effect constituted by each printing method, it is an essential condition that at least only the printing process is independent. Therefore, it is extremely important to take care so that the printing composition obtained by printing and drying the cloth by the preceding printing method does not hinder the printing operation by the subsequent printing method.

For example, in the conventional screen printing, it is determined by confounding the fiber material and its form, pattern, color arrangement and hue, the applicable dye group, the quantity and quality of the printed product, the printing method, the consumer quality requirements and the like. It is well known that there are merits and demerits with respect to each of the original pastes used in accordance with the color paste prescription and the examples of the prescriptions for the combination thereof. However, from the present invention which constitutes a composite pattern of plate printing and plateless printing, the printing workability of plateless printing combined with the pre-process or post-process of plate printing must be sufficiently considered. In general, in the system where plate printing is adopted after plateless printing, the color paste applied to plate printing can be diverted to the conventional formulation, but bleeding into delicate unfixed designs printed by plateless printing Prevention requires meticulous measures.

On the contrary, in contrast to the method of combining the plate-shaped printing which can relatively ease the management accuracy of the printing operation after the plate-less printing, the plate-less printing for the plate-less printing for which a higher printing operation is desired is desired. In the method of arranging later, the color paste used for plate printing is “paste crack”, “paste splash”, and “rubbing stain” after printing and drying.
A composition that can suppress the "dye transfer" or the like and has little morphological stability or variation in hand feeling of a printed fabric is selected, and a sizing agent capable of extremely reducing the solid content is required. In other words, it is inevitable to seek application from a synthetic paste system having a high molecular weight. In addition, it is naturally important to prevent bleeding by the non-printing printing ink in the unfixed color paste area printed by the plate printing.

However, in general, with regard to application of these synthetic pastes to printing, many advantages as compared with natural pastes have been conventionally proposed, but on the other hand, electrolytes which are inferior in sharpness of pictures and have poor sharpness. Disadvantages such as instability and relative decrease in color developability were pointed out, and are currently only practically used in some of the pigment printings in which notterpening or terpening properties are emphasized. It cannot be suitably applied.

Further, as a problem of plateless printing, when compared with printing in which a color copy technique by an ink jet system for reproducing a pattern on a paper surface at the stage of practical application is applied to a fiber assembly, Some intervening technical issues to be improved are extracted. That is, the irregularity of the fiber aggregate surface is remarkable as compared with the surface of the recording paper which is macroscopically smooth. The substrate of the recording paper is cellulose except for a special case such as an OHP film. Substrates are often very complex.Printing requires a relatively large amount of coloring composition for printing using only a small amount of ink. The quality of the pattern, which needs to penetrate inside, is not only the former color density and sharpness,
In the latter case, comprehensive evaluation of color depth, painting, etc. is required.
Compared to the fact that printing patterns are mainly regulated against discoloration during storage, printed products must take dyeing fastness into consideration when they are dry and wet. Technical measures will be required to improve quality characteristics such as compliance with absolute requirements.

Of course, in order to emphasize the sharpness of the picture, as inferred from the conventional printing technology, it is necessary to increase the viscosity of the paste and take measures against drying with electric heat or hot air to increase the drying speed of the color paste on the cloth. Although it has been adopted, it is not applicable when applying a combination of plate printing and plateless printing, because it promotes clogging of a screen type and a nozzle.

[0015]

Means for Solving the Problems The present inventors can secure a quality relatively similar to hand-painted yuzen in order to efficiently produce printed products of various kinds and small lots in the textile market where individualization is required. The present invention has been established by earnestly studying a technique for combining a computer printing technique which applies an image processing technique capable of efficiently providing a differentiated delicate pattern to a hand printing technique. That is, the method of imparting a pattern to the fiber structure of the present invention by plate printing and plateless printing is performed by applying a water-soluble thermoreversible polymer compound on the surface of the material to be printed or coexisting in the coloring composition, Composed of printing and non-printing printing, a composite product is made to appear on a fiber product.

The plate printing method applicable to the present invention is based on the conventionally used hand screen printing technique. A screen type cloth is laid on a screen printing table by using a screen type. It is possible to adopt a method in which the printing paste is manually printed. For non-printing printing, images that are copied, moved, enlarged, reduced, color-changed, etc., on a graphic drawn on a CRT screen or a graphic read by a scanner using a CG (computer graphics) system. The method of printing with an inkjet printer linked to the processing technology can be applied. Among them, a device that is a drop-on-demand type inkjet printer frequently used for a color output device and modified for a fiber assembly is preferable. It is.

As the coloring composition applied to the plate printing in the present invention, in a method of combining the plate printing after the plateless printing, a high temperature having a phase transition temperature in a low temperature region in order to secure a sharper pattern. It is important to use N-isopropylamine acryl amide or N-isopropylol acryl methamide polymer as a hydrophobic thermoreversible polymer together.

Further, in the method of combining plate-less printing and plate-less printing, the paste solid matter on the cloth after printing is dried is relatively reduced, and the morphological stability and the feeling of the printed cloth are changed. In order to secure the sharpness of the pattern while suppressing it, as the pasting agent for plate printing, conventionally known polyvinyl alcohol-based, polyethylene glycol-based, polyethylene oxide-based, maleic acid copolymer-based or polyvinylpyrrolidone-based, etc. N-Isopropylacryl amide or N as a high temperature hydrophobic thermoreversible polymer compound having a phase transition temperature in a low temperature range from polyacryl or polyacryl methamide type polymer compounds in place of the so-called synthetic sizing agent It has been confirmed that applying the isopropylemethacrylic amide polymer gives very good results.

As the coloring composition used for plateless printing in the present invention, a known ink composition for ink-jet printing composed of a dye group applicable to a fiber material can be used. In order to ensure the sharpness of the printing ink at the time of painting and to promote the penetration of the ink into the fiber assembly, the poly N-isopropyl acryl should be used as long as the stability of the ink composition or the aqueous dye solution is not hindered. It is desirable to use amide or poly N-isopropyl methacrylamide in combination.

However, the compatibility between the coloring composition consisting of a combination of various dyes and combination auxiliary agents applicable to the present invention and poly N-isopropyl acrylate or poly N-isopropyl methacrylate is all good. It is also assumed that the above cannot always be guaranteed. Therefore, in order to reproduce the printing properties of the high-temperature hydrophobic thermoreversible polymer in the low-temperature region, a method in which the polymer compound is applied to the printing surface in advance can be substituted. These pretreatment methods have an advantage that the optimum formulation can be incorporated mainly on the stability of the coloring composition.

The textile products printed by plate printing and plateless printing employed in the present invention include water-soluble adhesives such as glue, British gum, polyvinyl alcohol, polyacrylic acid copolymer, polyvinyl methyl ether, vinegar. A water-soluble pressure-sensitive adhesive such as a bi-carboxylic acid copolymer is more preferable than an emulsion of an acrylate ester or an organic solvent solution-based pressure-sensitive adhesive. In particular, the replacement of the unfixed dyed fabric at the time of switching between plate printing and plateless printing is important from the viewpoint of avoiding the interposition of moisture and eliminating troubles in printing in the next step such as dye flying and deformation of the fabric. In addition, it is not desired that the adhesive strength between the printing stand and the fiber aggregate is necessarily strong.

In particular, depending on the structure of the fiber assembly, etc., the form of the fabric is remarkably stabilized by the pretreatment with the high-temperature hydrophobic thermoreversible polymer. is there. The pretreated polymer compound exhibits a hydrophobizing function at a temperature of 30 ° C. or higher, which is relatively close to a normal state as a printing work environment, but is extremely soluble in a low temperature region below the temperature, and is subjected to post-treatment. Can be easily removed in the water washing step, and there is no problem in hand.

The high-temperature hydrophobic thermoreversible polymer compound, which is an essential condition for effectively carrying out the present invention, has a phase transition temperature within a range that does not significantly impair the printing conditions and working environment. It is desirable that the phase transition temperature can be regulated very sharply, for example, fibrous derivatives represented by methylcellulose and hydroxypropylmethylcellulose, partially saponified polyvinyl acetate, polyethylene oxide, polyvinyl oxolidinone, butadiene and maleic anhydride. 50, such as an alternating copolymer of
The present invention cannot be achieved by a conventionally known thermoreversible polymer compound that becomes insoluble by thermal gelation or the like at a temperature of not less than ° C. This is because the thermoreversible polymer compound having a relatively high phase transition temperature can cause clogging of the mold during printing, change in the flowability of the color paste, and This is because it incorporates many problems such as clogging and deterioration of the printing work environment.

As the thermoreversible polymer compound preferably used in the present invention, a compound having a phase transition temperature in the range of 40 ° C. to 20 ° C. is basically selected, and N-isopropyl acrylamide or N-isopropylene is selected. Peel methacrylamide-based polymers, copolymers thereof and the like can be mentioned. These thermoreversible polymer compounds can be used alone or in combination with a usual printing paste. It is preferable that the polymer compound having a sharp transition of the phase transition temperature has a higher molecular weight produced by polymerization of a monomer than a polymer compound obtained by denaturing the polymer compound. Although the high-molecular polymer is in a broad sense and falls into the category of so-called synthetic sizing agents, its characteristic is first achieved by the application of the above-mentioned derivative which exhibits a sharp hydrophobization phenomenon at a phase transition temperature or higher in a low temperature region. However, the mechanism of action is fundamentally different from the simple use of a synthetic sizing agent. Adjusting the surface temperature of the printed textile product to the above temperature does not induce deterioration of the printing work atmosphere, and is recommended from the viewpoint of occupational safety and health. The phase transition temperature of the colored composition happens to be 2
In the case of around 0 ° C, a cooling treatment is necessary to keep the colored composition at 20 ° C or lower.

An aqueous solution of these linearly polymerized compounds having a high molecular weight exhibits Newtonian flow and generally has a high spinnability, and when used in combination with a coloring composition, there is a problem in printing suitability. However, as a countermeasure, it is solved by plastic fluidization by introducing cross-linking, which is applied to general synthetic sizing agents, or by compounding with intercalation compounds such as montmorillonite or smectite. You can Strictly speaking, some of these measures affect the phase transition temperature, so
After confirming the detailed phase transition temperature in advance, it is desired to consider to keep the surface temperature of the fabric to be printed above the phase transition temperature.

In any case, the application of the high-temperature hydrophobic thermoreversible polymer dope, which exhibits a phase transition point in a relatively low temperature region around 30 ° C., has a low viscosity and good fluidity at a temperature lower than the phase transition temperature. Above the phase transition temperature, the viscosity increases and becomes hydrophobic, the function of suppressing the bleeding of the coloring material is sharply reflected, and the viscosity of the polymer compound aqueous solution can be freely adjusted by adjusting the molecular weight. By making changes, the solid content of the color paste on the fabric can be corrected, and the workability at the time of secondary printing from the fabric texture can be greatly improved. Complicated unit operation can be cleared very easily.

Further, the high temperature hydrophobic thermoreversible polymer applied to the present invention is characterized in that it is readily soluble in cold water and, conversely, its solubility in hot water is reduced and gelation becomes insoluble. Therefore, it is easy to remove by washing with water after printing, and since the polymer substance flowing into the wastewater can be insolubilized and separated by heating, it has a built-in characteristic that can be recommended from environmental conservation measures.

A small pattern pattern with a position corresponding to a floral pattern part to be inserted is output by a pre-printed printing which is separately input, and the printing of the ground pattern is dried before printing by plateless printing. Next, the printing fabric obtained by the plateless printing was laid on a hand-printing stand coated with a pressure-sensitive type sizing agent, and 30 parts of a dye solution mainly composed of an acid dye and sodium alginate (3 Wt% paste) / NIPAM (molecular weight 10

Part of the flower pattern is printed by hand printing with four screen molds using a color paste obtained by mixing the two parts with each other, and after drying, is steamed at 100 ° C. for 30 minutes according to a conventional method, washed with water, soaped, After drying and finishing, a printed material having a floral pattern arranged in a small-print pattern was obtained.

When the printing processes obtained under the above conditions are compared, the following characteristics are observed. (1) Untreated fabrics have remarkably poor form stability, and pre-treated fabrics such as NIPAM and PVA can be introduced into a printer as they are, whereas untreated fabrics need to be grounded and introduced on a polyester film or the like. Become. (2) In the case where the temperature of the cloth at the receiving position of the discharged dye liquid is 32 ° C. as compared with 20 ° C., the tendency of the latter bleeding to be relatively reduced in both untreated and treated cloths can be confirmed. The back pass of the upper color paste is suppressed to 32 ° C. from 20 ° C., and the effect of the drying speed in the permeation process of the color paste in normal printing is reproduced, but the back pass rate of the treated fabric is related to the temperature of the fabric. No, NIPAM on fabric
Further, it can be seen that the absorption ability of the dye solution by PVA or the like is added and the tendency for the back-through effect to be suppressed occurs.

(3) The effect of preventing bleeding was not observed in the pretreatment of PVA, and a remarkable effect was observed in the pretreatment of NIPAM. In particular, the bleeding preventing effect judged to be caused by the hydrophobizing phenomenon at 32 ° C. was apparent. . (4) An appropriate amount of PW for the receiving layer
The coexistence of F is extremely effective in facilitating the instantaneous acceptance of the dye solution sprayed at a relatively low pressure into the polymer film of NIPAM formed on the fabric. However, it is important to avoid increasing the coexistence amount, because bleeding exceeding the suppression of bleeding due to hydrophobization above the phase transition temperature of NIPAM will be accelerated. PWF is PV
Compared with A, it is excellent in compatibility with NIPAM, and it is confirmed that it is also suitable as a pretreatment composition.

(5) Further, when comparing the color hue after vapor-fixing of the non-printed portion with the printed fabric at 32 ° C. in which bleeding is relatively suppressed, the untreated (K at the maximum absorption wavelength 600 nm) / S value is 11.6), NIPAM
(Same 10.9), PVA (same 11.3), NIPAM /
PWF (12.3), PVA / PWF (10.2)
It is presumed that the combined use of NIPAM, which has a remarkable bleeding effect, can provide a formulation that is comparable to the coloring surface. (6) When transferring the unprinted and dried fabric to plate printing in the next step, it is desired to control the untreated fabric to suppress a morphological change due to a peeling operation from the grounding film. In addition, the treated fabric is highly evaluated for the merit that the printed dry fabric can be grounded as it is.

(7) The quality of a pattern in which a floral pattern is arranged on a small pattern type finally obtained by printing on a plate and a plate is NI.
The PAM or NIPAM / PWF blended pretreated fabric was excellent, and the sharpness of the boundary region between the plateless printed pattern and the plate-printed pattern was remarkably observed. (8) These trends are YEL
It was also confirmed in a small pattern type by plateless printing using an aqueous solution of LOW, RED and BLUE dyes.

(1) The influence of the pretreatment in the printing, printing and drying processes by plate printing is not observed. (2) When transitioning to plateless printing, the pretreated fabric is superior in shape stability to the untreated fabric and has good workability. In particular, in the case of untreated fabrics, careful attention must be paid to "rubbing stains" of unfixed dyes when re-laying upon printing without plate printing. In addition, when sodium alginate is applied to the base paste, the degree of "rubbing stain" tends to decrease, but the shape change of the printing fabric is large,
The disadvantage is that the laying work takes time. (3) NIPAM / smectite pre-treated fabric has markedly improved sign sharpness in plateless printing. (4) The sharpness of the sign portion is excellent in the pre-treated fabric, and there is a large difference in the product quality.

Therefore, in comparison with the small pattern type obtained from the former, the small pattern type composed of the latter is 1% of NIPMAM (5% by weight paste) / modified starch (12% by weight paste) in the next plate printing. Even with the color paste for disperse dyes prepared by adding to the 1: compounding paste, the blurring of the ground pattern affects the insertion of the pattern, and the improvement of the quality at the border between the two cannot be achieved. Further, it is possible to raise the level of the coloring hue depending on the fixing conditions by using a deep dye together.

The sharpness of the pattern printed on the fabric at 32 ° C. is remarkably superior to that obtained from the color paste from which the NITPAM component has been removed. Next, a polyester composition is laid with a pressure-sensitive adhesive to form a coloring composition, in which the direct dye aqueous solution prepared in Example 1 is combined with 1.0% by weight of NIPMAM having a molecular weight of 100,000 and 0.2% by weight of synthetic smectite. Is ejected from an ink jet printer to complete the small-print pattern pattern printing without printing. The fabric is subjected to color development and post-treatment in accordance with a conventional method, followed by finish drying. It was confirmed that the sharpness of the pattern by the ink combined with NIPMAM and smectite was excellent, and the color hue and the print quality were good, as compared with the small-textured ground pattern of the ink composition of Example 1.
