Description

Technical Field

[0001] This invention relates to a plush-type raised foam silicone resin, a printing agent containing the same, and a method for utilizing the same.

[0002] Printing methods and printed materials. Background Technology

[0003] Generally, dyeing methods for textiles include immersion dyeing, which involves immersing the textiles in a solution of dyes and other auxiliaries, and printing, which involves using a screen or roller to print (print) a mixture of dyes or pigments with a paste onto the surface of the textiles.

[0004] Immersion dyeing refers to immersing the object to be dyed in a dyeing solution until it is completely dyed the same color. In most cases...

[0005] In general, it is a general term used for dyeing solid colors. Most of it utilizes mechanical devices, which are very simple.

[0006] In this process, a portion of the material to be dyed is immersed in the dyeing solution while being rotated. Typically, cotton, silk, and other materials are used in this method.

[0007] Textiles such as rayon use jiggers, while wool textiles use winches.

[0008] The jigger is a simple dyeing machine consisting of two rollers and a dyeing cylinder.

[0009] One roller winds the fabric, feeding it into the dyeing solution, then it is wound onto another roller.

[0010] Then, dye the product while wrapping it in the opposite manner, repeating this process until the product is visible.

[0011] The desired color tone. The winch is horizontally inserted on both sides of an oval or circular plate.

[0012] A device consisting of multiple rods fixed in place, which moves the fabric by rotating them, used when dyeing wool textiles.

[0013] Circular shapes are used for staining, elliptical shapes are used otherwise. Furthermore, when staining large quantities, a series of connections are used.

[0014] A continuous dyeing machine that performs dyeing, washing, arranging, and drying.

[0015] Printing refers to the method of dyeing patterns onto fabrics, although it can also be done on paper or other materials.

[0016] It is used in materials, but to color threads or textiles, especially to color parts of textiles to reveal the desired effect.

[0017] The technique of pattern printing. Printing can be classified in many ways, including synthetic textiles and cotton textiles.

[0018] Printing on cotton, printing on wool fabric, printing on silk fabric, etc. are classified according to the kind of fiber on which printing is performed

[0019] Printing by machine, printing by hand, etc. are classified according to whether the printing operation is performed by machine or by hand.

[0020] Printing by machine, printing by hand, etc. are classified according to whether the printing operation is performed by machine or by hand.

[0021] The printing by machine is further classified into roller printing, automatic screen printing, rotary screen printing, transfer printing, digital textile printing (DTP), etc.

[0022] Roller printing is a method in which a pattern is engraved in relief on a roller formed of copper or iron, dye is applied to the engraved portion, and a fabric is passed through to perform printing, and is the oldest method of machine printing, and is mostly used for simple patterns with few colors, stripe patterns, and dot patterns.

[0023] Automatic screen printing is the most commonly used method of machine printing in which a screen frame is fixed on a printing table set in balance, a squeegee applies dye up and down, and a fabric attached to a conveyor belt is automatically moved to a position corresponding to the screen frame.

[0024] Rotary screen printing is a method in which a flat screen frame of automatic screen printing is replaced with a cylindrical metal screen frame, the screen frame is rotated, and a fabric attached to a conveyor belt is continuously moved to print a pattern, and is a machine improved by combining a roller printing machine and an automatic screen printing machine.

[0025] Transfer printing is a method in which a transfer dye is printed on paper, and a fabric is pressed against the printed paper while heat is applied to perform printing on the fabric, and is a method in which printing technology is applied to printing in order to obtain a fine actual effect.

[0026] Hand screen printing is further classified into block printing, stencil printing, spray printing, batik printing, discharge printing, tie-dyeing, intaglio printing, and slub printing, and block printing is a method in which a pattern is engraved on a wood, rubber, or linoleum plate, and dye is applied to perform printing, and is the oldest method of printing in the history of printing, and is the same as stamping.

[0027] Stencil printing is a method of scraping a dye over a fabric after cutting out a desired pattern shape using a knife, scissors, etc. and placing the cut-out paper pattern on the fabric, and is a method that can also be performed by a spray method.

[0028] Spray printing is a method of printing using a method of spraying a dye of a desired color after placing a paper pattern engraved with a desired pattern on a fabric, a method of spraying another color over a desired pattern shape drawn using a dye with a reducing agent or a water repellent agent, a method of spraying a plurality of colors over the entire fabric using a spray machine, etc.

[0029] Batik printing is a method mainly performed by hand by the Javanese, and refers to a printing method in which a crack effect highlighted by a crack generated by regular or irregular rubbing or folding is shown by applying a dye after drawing a base drawing or a pattern using wax, paraffin, etc.

[0030] As described above, in the case of a fabric used in a textile or the like, a fabric with a desired color or shape can be processed by the above-described various printing methods, but these printing methods have limitations in the realization of the beauty of the textile because the pattern shape is flat, and thus, a method for expressing a more diverse three-dimensional pattern shape by solving the problem of being able to obtain only a flat beauty is required.

[0031] As a first method for imparting the above-described three-dimensionality, a method of adding small stones to a fabric generally produced to generate a three-dimensional pattern or a printing process for a textile expressing three-dimensionality has been used in the related art.

[0032] However, the existing printing method for imparting three-dimensionality is limited in application to inkjet printing, transfer printing, or digital textile printing commonly used recently, and thus, there is an increasing demand for a printing material capable of imparting three-dimensionality in a manner different from the related art. SUMMARY

[0033] TECHNICAL PROBLEM

[0034] The existing printing material using silicone has a problem of having only a flat beauty effect, a hard touch, and no or insufficient stretchability, and thus, an object of the present application is to provide a printing material capable of imparting a shiny and improved soft touch, etc. by using a pile type raised foamed silicone resin having a specific composition capable of improving the above-described problems as a printing material, and a printed product obtained by a printing process using the same.

[0046] The term "velvet effect" used in the present invention means a velvet, suede leather feel from the visual and tactile senses.

[0047] Hereinafter, the present invention will be described in more detail.

[0048] The silicone resin composition for printing according to the present application, as a pile type raised foaming resin, comprises a silicone resin (main resin), a foaming agent, and a carbomer, preferably, 9.7 to 20 weight percent of the foaming agent, 0.3 to 1.0 weight percent of the carbomer, and the remaining amount of 100 weight percent of the silicone resin, more preferably, 12.0 to 17.0 weight percent of the foaming agent, 0.4 to 0.9 weight percent of the carbomer, and the remaining amount of 100 weight percent of the silicone resin.

[0049] The C1 to C4 alcohol is included as the foaming agent in the composition of the silicone resin for printing, preferably, the C1 to C3 alcohol can be included, and more preferably, ethanol and / or propanol can be included. Also, the alcohol used as the foaming agent uses almost 100% alcohol not including water, because if water (moisture) is included, it brings an adverse effect to the foaming and raised formation.

[0050] Also, if the content of the foaming agent in the silicone resin for printing is less than 9.7 weight percent, the suede texture effect is minimal, and if the content of the foaming agent in the silicone resin for printing is more than 20.0 weight percent, the raised product is easily broken due to the excessively high foaming power, and also the mixing and dispersion of the components in the resin are not good due to the excessively high viscosity of the resin, and thus, it is preferable to use within the range.

[0051] In the composition of the silicone resin for printing, the carbomer functions to adjust the viscosity, and if the content of the carbomer in the silicone resin for printing is less than 0.4 weight percent, it does not have the viscosity adjustment effect caused by the use thereof or the effect is minimal due to the excessively small content, and if the content of the carbomer is more than 1.0 weight percent, there is a problem in that the mixing of the other components of the printing agent is reduced, and thus, it is preferable to use within the range.

[0052] Also, the silicone resin as the main resin in the silicone resin for printing can include a vinyl-terminated polydi(C1 to C3 alkyl) siloxane and silica, preferably, a vinyl-terminated polydi(C1 to C2 alkyl) siloxane and silica, and more preferably, a vinyl-terminated polydimethylsiloxane and silica.

[0053] The silica in the silicone resin can use silica having an average particle diameter of 200 nm to 3,000 nm, and preferably, can use silica having an average particle diameter of 400 nm to 2,000 nm. In this case, if silica having an average particle diameter of less than 200 nm is used, the silicone resin used for printing or the printing agent containing the same can all foam during heat treatment, and thus, a regular foam and a raised bump desired to be formed can not be formed. If the average particle diameter of the silica is greater than 3,000 nm, the bump can be formed too randomly. Therefore, it is preferable to use silica having a particle diameter within the range.

[0054] Also, the content of the silica in the silicone resin is 19 to 26 weight percent, and preferably, 21.0 to 25.0 weight percent, and more preferably, 21.5 to 24.5 weight percent. In this case, if the content of the silica in the silicone resin is less than 19 weight percent or greater than 26 weight percent, the bump can not be uniformly formed, and thus, the hiding power of the printed object and the velour effect of the printing process can be very small. Therefore, it is preferable to use the content within the range.

[0055] Also, the content of the vinyl-terminated polydi(Ci to C3 alkyl)siloxane in the silicone resin is the remaining amount of 100 weight percent excluding the silica.

[0056] The raised foam silicone resin having the composition as the mixture of the raised foam silicone resin composition of the present application is heat-treated at a temperature of 130 to 180°C, and preferably, at a temperature of 140 to 180°C, and more preferably, at a temperature of 145 to 178°C for 5 seconds or less, and preferably, for 2 seconds to 5 seconds, and thus, is foamed and raised in the form of a soap bubble or the like, and thus, the bump is formed (see the diagram of FIG. 1). The degree of foaming and raising can be adjusted by adjusting the content of the composition in the composition and the heat treatment temperature, time, and the like. Figure 1

[0057] Also, the foaming of the raised foam silicone resin of the present application can be foamed at a volume increase rate of 30 to 120 times, and preferably, at a volume increase rate of 60 to 120 times, and more preferably, at a volume increase rate of 80 to 115 times.

[0058] The raised foam silicone resin described above is introduced as a printing agent material to impart a velour effect to the printing agent, and can impart a shiny effect by reflecting light from the bump formed at the printed portion, and can impart a three-dimensional aesthetic sense. The printing height is high by 2 times or more, and thus, the production cost of the printed object can be reduced by reducing the number of times. Also, the printing agent has excellent color development ability of the pigment, and can express color even with a small amount of the pigment. ​

[0059] According to the preferred examples regarding the above-mentioned printing agent, the printing agent of the present application can include the pile type raised foamed silicone resin, a colorant, and an additive.

[0060] The colorant can include one or more selected from pigments and dyes.

[0061] The pigments can include one or more selected from neutral pigments and oily pigments, and preferably, the use of neutral pigments is more advantageous in terms of eco-friendliness.

[0062] The neutral pigments and / or oily pigments can use general pigments that can be purchased in the technical field to which the present application pertains.

[0063] Also, the additive can use general additives used in the technical field to which the present application pertains, such as titanium dioxide, a filler, a diluent, a curing agent, a dispersant, and / or a leveling agent, according to the printing object to be prepared.

[0064] Also, the stereoscopic beauty, the suede texture, the hiding power, and the like of the printing object (print) can be adjusted by adjusting the content of the pile type raised foamed silicone resin in the printing agent.

[0065] Various printing processes, such as screen printing, roller printing, transfer paper printing, or digital textile printing, can be performed using the printing agent.

[0066] The embodiments disclosed in the present application are only for illustrating the present application, and not for limiting the technical idea of the present application, and the scope of the technical idea of the present application is not limited to these embodiments. The scope of protection of the present application should be interpreted by the above-mentioned scope of protection, and all technical ideas within the same scope should be interpreted as included in the scope of protection of the present application.

[0076]

[0077]

[0078] Experimental Example 1: Measurement of Volume Change Rate and Raised Height

[0079] The pile type raised foamed silicone resins prepared in the examples and comparative examples were applied to a textile fabric at a thickness of about 0.4 mm, and after heat treatment at a temperature of 170 to 172°C for 4 seconds, the volume change rate before and after heat treatment was measured, and the results are shown in Table 2.

[0080] Examples 7 to 8 and Comparative Examples 6 to 8 in Table 2 below are examples in which the pile type raised foamed silicone resin of Example 1 was foamed and raised to form raised products, and the average height and volume change rate were measured according to different heat treatment conditions. In this case, the volume change rate was calculated based on the volume before and after heat treatment based on the average height of the raised products.

[0081] Furthermore, a cross-sectional photograph of the raised products formed by foaming and raising the pile type raised foamed silicone resin of Example 1 is shown in FIG. 1. Figure 2 Figure 2 The cross-sectional photograph was taken by a video microscope at a magnification of 140 times by the Korea Testing Laboratory (KOTTI).

[0082] Furthermore, the surface state was evaluated by comprehensive tactile sensation such as suede texture, coating smoothness, and visual observation (O: excellent, Δ: ordinary, X: poor)

[0083] Table 2

[0084]

[0085]

[0086] ​As observed in Table 2, the embossed products of Examples 1 to 8 all showed high bump formation, high volume change rate, and excellent surface state. In comparison with Example 6 using propanol as the foaming agent, the case of using ethanol showed a slightly favorable tendency in bump height and volume change rate.

[0087] Also, in the case of Comparative Example 1 using a silicone resin not containing silica, a result showing reduced foaming power, uneven bump formation, and a slightly insufficient surface state was shown.

[0088] Also, in the case of Comparative Example 2 not using carbomer, the resin was absorbed by the textile fabric in large amounts, and as a result, bumps of low height were formed, the volume change rate was small, and there was a problem of greatly reduced suede texture.

[0089] Also, in the case of Comparative Example 3 using 1.2 weight percent of carbomer, which exceeds 1 weight percent, in comparison with Example 3, a result showing reduced foaming effect was shown.

[0090] Also, in the case of Comparative Example 4 using 9.2 weight percent of foaming agent, which is less than 9.7 weight percent, in comparison with Example 4 (12.2 weight percent), the volume change rate was greatly reduced in terms of bump height, and as a result, there was a problem of minimal suede texture effect.

[0091] Also, in the case of Comparative Example 5 using 20.8 weight percent of foaming agent, which exceeds 20 weight percent, in comparison with Example 5 (17.9 weight percent), a result showing reduced volume change rate and poor surface state was shown, because of the appearance of broken bumps due to excessive expansion, uneven bump formation, and as a result, a feeling of hardness and greatly reduced soft texture.

[0092] Also, in the case of Comparative Example 6 in which heat treatment was performed at a temperature of 125 to 127°C, a result showing low bump formation rate, low height, and poor surface state was shown.

[0093] Also, in the case of Comparative Example 7 in which heat treatment was performed at a temperature of 190 to 192°C, although the foaming property was good, there was a problem of the fabric as a base material being burned, and also a problem of uneven texture due to non-uniform formation of bumps.

[0094] Also, in the case of Comparative Example 8 in which heat treatment was performed for 6 seconds, which exceeds 5 seconds, a result showing no great difference from Example 1 was shown.
