Description

A file-type raised foam silicone resin composition for printing, a file-type raised foam silicone resin for printing, and a printing agent comprising the same

[0001] The present invention relates to a file-type raised foam silicone resin, a dyeing agent comprising the same, a dyeing method using the same, and a dyeing product.

[0002] Common methods for dyeing fabrics include immersion dyeing, in which the fabric is immersed in a solution of dyes and other preparations and dyed, and screen printing, in which a mixture of dyes, pigments, etc. is mixed with a base material and printed onto the surface of the fabric using a screen or roller.

[0003] Immersion dyeing is the process of immersing a fabric in a dye solution and dyeing the entire fabric a uniform color. It is often used as a general term for plain dyeing. Most fabrics use a mechanical device, which is very simple. The fabric is partially immersed in the dye solution while rotating. A jigger is generally used for cotton, silk, and rayon fabrics, while a wince is used for woolen fabrics. The jigger is a simple dyeing machine consisting of two rollers and a dyeing tub. The fabric is wound around one roller, immersed in the dye solution as it is fed, and then wound around the other roller. Next, the fabric is wound in the opposite direction and dyed. This process is repeated several times until the desired shade is achieved. The wince consists of several bars fixed across two oval or circular plates, which rotate to move the fabric. A circular type is used for immersion dyeing woolen fabrics, while an oval type is used for other purposes. Also, when dyeing in large quantities, a continuous dyeing machine is used that connects dyeing, washing, blowing, and drying in a single line.

[0004] Dyeing is a method of dyeing patterns on fabric. It is also used on paper and other materials, but it is a technique that partially colors thread or fabric, especially fabric, to create a desired pattern. Dyeing can be classified by several methods. The classification is based on the type of fiber used for printing, such as synthetic fabrics, cotton fabric printing, wool fabric printing, and silk fabric printing. The classification is also based on whether the printing process is mechanical or manual, such as machine printing and hand printing.

[0005] The above mechanical printing is further classified into roller printing, automatic screen printing, rotary screen printing, transfer printing, and DTP (digital textile printing).

[0006] Roller printing is a method of engraving motifs into a copper or iron cylinder (roller), applying dye to the engraved area, and passing it through the fabric to dye. It is the oldest mechanical printing method and is often used for simple patterns with a small number of colors, stripe patterns, and dot patterns.

[0007] Automatic screen printing is the most widely used mechanical printing method these days, in which a screen frame is fixed on a printing stand installed in a flat manner, a squeegee scrapes the dye up and down, and the fabric attached to a belt automatically moves to fit the screen frame.

[0008] Rotary Screen Printing is a method in which the flat screen frame of automatic screen printing is replaced with a cylindrical metal screen frame. The screen frame rotates and the fabric attached to the belt continues to move, so the pattern is printed. It uses an improved machine that combines a roller printing machine and an automatic screen printing machine.

[0009] Transfer printing is a method of printing on fabric by printing transfer dye on paper and then pressing the fabric and printed paper together with heat at an appropriate temperature. It is the application of printing technology to dyeing to achieve a delicate realistic effect.

[0010] Hand screen printing is further divided into block printing, stencil printing, spray printing, batik printing, lithography printing, gravure printing, and block printing. Block printing is a method of carving a pattern on wood, rubber, and linoleum plates and then applying dye to them to create a stamp, similar to stamping, and is the oldest printing method in the history of printing.

[0011] Stencil printing is a method of creating a pattern by cutting out the desired motif shape with a knife, scissors, etc., placing the cut-out paper on the fabric, and then scratching dye onto it. It also refers to a method of spraying.

[0012] Spray printing is a dyeing method that uses methods such as placing a pattern with a desired motif shape on the fabric and spraying a dye color, drawing the desired motif shape with a dye containing a reducing or repellent agent and spraying a different color on top to create a pattern, or spraying multiple colors with a sprayer over the entire fabric.

[0013] Batik printing is a method that Javanese people mainly used by hand. It is a printing method that uses lead, wax, paraffin, etc. to draw a background or motif, then applies dye, and then regularly or irregularly crumples or folds to create a random effect, and is excellent for cracking.

[0014] As previously discussed, in the case of fabrics used for textiles, etc., it is possible to process fabrics with desired colors and shapes using the various dyeing methods described above. However, since these dyeing methods have flat patterns, they are inevitably limited in realizing the aesthetics of the fabric. Therefore, a method is required to solve the problem of only being able to obtain flat aesthetics and to obtain fabrics that can express more diverse and three-dimensional patterns.

[0015] As a method for imparting this three-dimensional effect, conventionally used in the field of technology are methods of adding stone grains to fabrics to create three-dimensional patterns, or fabrics with three-dimensional effects are dyed.

[0016] However, existing dyeing methods that impart this three-dimensional effect have limitations in applying them to inkjet dyeing, transfer dyeing, or recently widely used digital textile printing, and thus, there is an increasing demand for dyeing materials that can impart a three-dimensional effect in a different way from existing methods.

[0017] The purpose of the present invention is to provide a dyeing material and a printed product dyed using the same, which can provide a three-dimensional effect through a velvet effect, shine, and an improved soft touch to a dyed print by applying a pile-type, pile-type raised foam silicone resin of a specific composition that can improve the problems of existing dyeing materials using silicone having only a flat aesthetic effect and being hard to the touch and having no or insufficient elasticity.

[0018] The present invention, which aims to achieve the above-mentioned purpose, relates to a pile-type raised foam silicone resin composition for dyeing, comprising a silicone resin, a foaming agent and a carbomer.

[0019] In addition, the present invention relates to a dyeing agent comprising a mixture of the above-described pile-shaped raised foam silicone resin composition (piled pile-shaped raised foam silicone resin).

[0020] In addition, the present invention relates to a dyed article that has undergone dyeing treatment using the above dyeing agent.

[0021] In addition, the present invention relates to a dyeing method using the above dyeing agent.

[0022] The file-type raised foam silicone resin for printing according to the present invention has the characteristic of foaming when heat-treated at a specific temperature to form raised shapes like soap bubbles, and thus, a printing agent applying this as a printing material can impart a velvet effect and reflect light to impart a sparkling effect (or hiding power), and since the printing height is increased by more than twice, the number of printings can be reduced, thereby drastically reducing the production cost of the printed material, and since the coloring power of the coloring agent in the printing agent is excellent, color expression is possible even with a small amount of pigment, and the formed printing area has a soft feel and excellent elasticity.

[0027] The term "velvet effect" used in the present invention means having a silky, suede texture visually and tactilely.

[0028] The present invention is described in more detail below.

[0029] The silicone resin composition for printing of the present invention is a pile-type raised foam resin, and comprises a silicone resin (main resin), a foaming agent, and a carbomer, preferably comprises 9.7 to 20 wt% of the foaming agent, 0.3 to 1.0 wt% of the carbomer, and the remaining amount of the silicone resin among 100 wt%, and more preferably comprises 12.0 to 17.0 wt% of the foaming agent, 0.4 to 0.9 wt% of the carbomer, and the remaining amount of the silicone resin among 100 wt%.

[0030] Among the silicone resin compositions for printing, the foaming agent may include a C1 to C4 alcohol, preferably a C1 to C3 alcohol, and more preferably ethanol and / or propanol. In addition, the alcohol used as the foaming agent is an alcohol that does not contain water and is almost 100% alcohol, because if it contains water (moisture), it may have a negative effect on the foaming and bulge forming ability.

[0031] In addition, if the content of the foaming agent in the silicone resin for printing is less than 9.7 wt%, the suede texture effect may be insufficient, and if the content of the foaming agent in the silicone resin for printing is more than 20.0 wt%, the foaming power may be too high, causing the raised product to break easily, and the viscosity of the resin may be too high, and the miscibility and dispersibility of the components in the resin may not be too good, so it is appropriate to use it within the above range.

[0032] Among the silicone resin compositions for printing, the carbomer plays a role in controlling viscosity. If the content of carbomer in the silicone resin for printing is less than 0.4 wt%, the content may be too small and the viscosity controlling effect due to its use may be absent or insignificant. If the content of carbomer exceeds 1.0 wt%, there may be a problem of poor compatibility with other components of the printing agent. Therefore, it is appropriate to use it within the above range.

[0033] And, among the silicone resin compositions for printing, the silicone resin, which is the main resin, includes vinyl-terminated polydi(C1-C3 alkyl)siloxane and silicon dioxide, preferably includes vinyl-terminated polydi(C1-C2 alkyl)siloxane and silicon dioxide, and more preferably includes vinyl-terminated polydimethylsiloxane and silicon dioxide.

[0034] The silicon dioxide in the silicone resin may have an average particle size of 200 nm to 3,000 nm, preferably an average particle size of 400 nm to 2,000 nm. In this case, if silicon dioxide having an average particle size of 200 nm is used, there may be a problem that the silicone resin for printing or the printing agent containing the same may be entirely foamed during heat treatment, and thus the regular foaming and raised raised products to be manufactured may not be formed. In addition, if the average particle size of the silicon dioxide exceeds 3,000 nm, there may be a problem that the raised products are formed too randomly. Therefore, it is appropriate to use silicon dioxide having a particle size range within the above range.

[0035] And, the content of silicon dioxide in the silicone resin is 19 to 26 wt%, preferably 21.0 to 25.0 wt%, more preferably 21.5 to 24.5 wt%. At this time, if the content of silicon dioxide in the silicone resin is less than 19 wt% or more than 26 wt%, the raised material is not formed evenly, so there may be a problem that the hiding power and velvet effect of the dyed product are poor. Therefore, it is appropriate to use it within the above range.

[0036] And, the content of vinyl-terminated polydi(C1-C3 alkyl)siloxane in the silicone resin is the remaining amount of 100 wt% excluding silicon dioxide.

[0037]

[0038] The pile-type raised foam silicone resin, which is a mixture of the pile-type raised foam silicone resin composition of the present invention having the above composition, foams and raises when heat-treated at 130 to 180°C, preferably 140 to 180°C, and more preferably 145 to 178°C for less than 5 seconds, preferably 2 to 5 seconds, to form raised products in the form of soap bubbles or the like (see the schematic diagram in Fig. 1), and the degree of foaming and raising can be controlled by controlling the content of the components in the composition and the heat treatment temperature, time, etc.

[0039] And, the file-type raised foam silicone resin of the present invention can be foamed at a volume increase rate of 30 to 120 times, preferably 60 to 120 times, and more preferably 80 to 115 times.

[0040]

[0041] The previously described file-type raised foam silicone resin can be introduced as a dyeing agent material to impart a velvety effect to the dyeing agent. Light is reflected by the raised materials formed in the dyed area, imparting a sparkling effect. It also imparts a three-dimensional aesthetic. Furthermore, the dyeing height can be more than doubled, reducing the number of dyeing cycles and significantly reducing the production cost of the dyeing agent. Furthermore, the excellent coloring power of the pigments within the dyeing agent allows for color expression even with a small amount of pigment.

[0042] As a preferred embodiment of such a dyeing agent, the dyeing agent of the present invention may include the above-described file-type raised foam silicone resin, a coloring agent, and an additive.

[0043] The above coloring agent may include at least one selected from pigments and dyes.

[0044] The above pigment may include at least one selected from a neutral pigment and an oil-based pigment, and it is advantageous from an eco-friendly perspective to use a neutral pigment.

[0045] The above neutral pigment and / or oil pigment may be a general pigment available in the art.

[0046] In addition, the additives may be general additives used in the art, such as sugar, filler, diluent, hardener, dispersant, and / or leveling agent, depending on the dyeing material to be manufactured.

[0047] In addition, the three-dimensional aesthetics, suede texture, and hiding power of the dyed material (printed material) can be controlled by adjusting the content of the file-type raised foam silicone resin in the dyeing agent.

[0048] Using the above dyeing agent, various dyeing treatments such as screen printing, roller printing, transfer paper printing, or digital textile printing can be performed.

[0049]

[0050] The embodiments disclosed in the present invention are intended to illustrate, rather than limit, the technical concepts of the present invention. These embodiments do not limit the scope of the technical concepts of the present invention. The scope of protection of the present invention should be interpreted according to the following claims, and all technical concepts within the scope equivalent thereto should be construed as being included within the scope of the present invention.

[0051] [Example]

[0052] Example 1: Preparation of a file-type raised foam silicone resin

[0053] A silicone resin was prepared by mixing 23.0 wt% of silicon dioxide with an average particle diameter of approximately 1,200 nm and 77.0 wt% of vinyl-terminated polydimethylsiloxane.

[0054] A pile-type raised foam silicone resin was prepared by mixing 15.3 wt% of ethanol at a concentration of about 100% as a foaming agent, 0.62 wt% of carbomer, and the remaining balance of 100 wt% of the above silicone resin.

[0055]

[0057] A file-type raised foam silicone resin was manufactured in the same manner as in Example 1, but a file-type raised foam silicone resin having a composition as shown in Table 1 below was manufactured, and Examples 2 to 4 and Comparative Examples 1 to 4 were performed, respectively.

[0058]

[0059] Example 6

[0060] A file-type raised foam silicone resin was manufactured in the same manner as in Example 1, but propanol with a concentration of about 100% was used instead of ethanol as a foaming agent.

[0062] Experimental Example 1: Measurement of volume change rate and height of the bulge

[0063] The file-type raised foam silicone resin manufactured in the above examples and comparative examples was coated on a fabric to a thickness of about 0.4 mm, and then heat-treated at 170 to 172°C for 4 seconds. The volume change rate before and after the heat treatment was measured, and the results are shown in Table 2 below.

[0064] Examples 7 to 8 and Comparative Examples 6 to 8 in Table 2 below use the file-type raised foam silicone resin of Example 1, but are formed by foaming and raising under different heat treatment conditions as follows, and the average height and volume change rate of the raised product are measured. In this case, the volume change rate is calculated by calculating the volume before and after heat treatment based on the average height of the raised product.

[0065] [Correction under Rule 91 14.03.2025] And, the cross-sectional photograph of the raised foam silicone resin of Example 1 foamed and raised to form a raised material is shown in Fig. 2, and the cross-sectional photograph of Fig. 2 was taken at 140 times magnification using a video microscope at the request of KOTTI Testing & Research Institute.

[0066] And, the surface condition was evaluated through comprehensive tactile and visual observation, such as suede texture and coating smoothness (○: Excellent, △: Average, X: Poor)

[0067] Heat treatment conditions Temperature / time Height of raised material (average height) Volume change rate Surface condition Example 1 170~172℃ / 4 sec 1.2 mm 113 Bae ○ Example 2 170~172℃ / 4 sec 1.1 mm 98 Bae ○ Example 3 170~172℃ / 4 sec 1.0 mm 92 Bae ○ Example 4 170~172℃ / 4 sec 0.8 mm 46 Bae ○ Example 5 170~172℃ / 4 sec 1.3 mm 135 Bae ○ Example 6 170~172℃ / 4 sec 1.0 mm 94 Bae ○ Example 7 140~142℃ / 4 sec 0.8 mm 33 Bae △ Example 8 150~152℃ / 4 sec 1.0 mm 65 Bae ○ Comparative Example 1 170~172℃ / 4 sec 0.7 mm 27 Bae X Comparative Example 2170~172℃ / 4 sec 0.4 mm 17 times X Comparative example 3170~172℃ / 4 sec 0.8 mm 52 times △ Comparative example 4170~172℃ / 4 sec 0.6 mm 26 times X Comparative example 5170~172℃ / 4 sec 1.3 mm 96 times △ Comparative example 6125~127℃ / 4 sec 0.2 mm 5 times X Comparative example 7190~192℃ / 4 sec 1.3 mm 143 times △ Comparative example 8170~172℃ / 6 sec 1.2 mm 112 times ○

[0068] As can be seen in Table 2 above, the dyeing materials of Examples 1 to 8 generally showed high formation of raised particles, high volume change rate, and excellent surface condition. As a foaming agent, the use of ethanol was relatively more advantageous than that of Example 6, which used propanol, in terms of raised particle height and volume change rate.

[0069] In addition, in the case of Comparative Example 1 using a silicone resin that does not contain silicon dioxide, the foaming power was low, the raised parts were not formed evenly, and the surface condition was somewhat poor.

[0070] In addition, in the case of Comparative Example 2, which did not use carbomer, a large amount of resin was absorbed into the fabric, resulting in the formation of raised areas with a low height and a small volume change rate, resulting in a problem of a significant deterioration in the suede texture.

[0071] In addition, in the case of comparative example 3, which used 1.2 wt% of carbomer, which exceeded 1 wt%, the foaming effect was rather reduced compared to example 3.

[0072] In addition, in the case of Comparative Example 4, which used only 9.2 wt% of the foaming agent, which is less than 9.7 wt%, the height and volume change rate of the raised material were significantly lower than in Example 4 (12.2 wt%), and as a result, there was a problem that the Swedish texture effect was insufficient.

[0073] In addition, in the case of Comparative Example 5 using 20.8 wt%, which is more than 20 wt% of the foaming agent, the volume change rate was lowered and the surface condition was not good compared to Example 5 (17.9 wt%), which was due to excessive expansion, resulting in broken raised parts and uneven formation of raised parts, and as a result, the dyeing surface felt somewhat hard and the soft texture was greatly reduced.

[0074] In addition, in the case of Comparative Example 6, where heat treatment was performed at 125 to 127°C, the formation rate of raised particles was low, the height was also low, and the surface condition was not good.

[0075] In addition, in the case of comparative example 7, where heat treatment was performed at 190 to 192°C, the foaming property was good, but there was a problem of the fabric corresponding to the substrate burning, and there was a problem of the texture being uneven because the raised material was not formed evenly.

[0076] And, in the case of comparative example 8, where heat treatment was performed for 6 seconds rather than 5 seconds, the results showed no significant difference from Example 1.

[0077]
