TECHNICAL FIELD The present invention relates to an anti-slip textile sheet and a process of preparing the same. More particularly, the present invention relates to an anti-slip textile sheet and a process of preparing the same, which is superior in anti-slip property and has a fine touch as a silicon resin is partially printed on the textile sheet with a fine touch, and which is very useful as materials of golf gloves, apparel or the like as the stripping strength and abrasion strength between the textile sheet and the printed silicon resin is superior.

BACKGROUND ART As a conventional anti-slip textile sheet, as shown in Fig 2, products made by printing a silicon resin on a general fabric in an embossed state have been widely used.

Specifically, Korean Utility Model Laid-Open No. 1999-21918 suggests a method of preventing slippage upon wearing by forming a silicon resin in an embossed state on the foot sole portion of stockings and tights.

However, the anti-slip textile sheet made by the above method is problematic in that as the stripping strength between the fabric and the silicon resin is low and the abrasion strength measured by the ASTM D 3884-92 method is about 500 times, which is very low, the printed silicon resin is stripped off when used for a long time to thus gradually degrade the

anti-slip property and the touch is bad upon wearing.

Meanwhile, Korean Patent Laid-Open No. 2001-25143 and the same No. 2001-35215 disclose methods for overall coating a silicon resin effectively on a textile sheet (woven or knitted fabric) for a swimming suit or swimming cap in order to increase waterproof effect.

However, the above-mentioned methods are problematic in that the cost of production rises and the anti-slip effect is poor since the purpose of coating the silicon resin is to increase the waterproof effect not the anti-slip property and the silicon resin is overall coated on the textile sheet.

It is an object of the present invention to solve the conventional problems described above by providing an anti-slip textile sheet, which maintains anti-slip property for a long time as the stripping strength and abrasion strength between the textile sheet and a silicon resin is superior, and which can be used as materials of golf gloves, apparel or the like as it has an excellent touch.

It is another object of the present invention to maintain anti-slip property for a long time by improving the stripping strength and abrasion strength between a textile sheet and a silicon resin when the silicon resin is printed on the textile sheet in a specific shape for giving the anti-slip property.

It is yet another object of the present invention to enable an anti-slip textile sheet to be used as materials of golf gloves, apparel or the like as well as sundry goods such as shoes, rugs and car sheets by improving the touch of the anti-slip textile sheet.

It is still another object of the present invention to provide a method of preparing an anti-slip textile sheet with excellent touch, anti-slip property and stripping strength by a continuous or discontinuous process.

DISCLOSURE OF INVENTION To achieve the above objects, there is provided an anti-slip textile sheet in accordance with the present invention, wherein a silicon resin (2) is coated on parts of the surface of the anti-slip textile sheet (1) consisting of an inside having the portions where ultra fine fibers (la) are interlaced with each other and the portions where a polyurethane resin (1b) is impregnated, both portions being irregularly repeated, and a surface on which the ultra fine fibers (la) are raised, and the stripping strength between the textile sheet (1) and the silicon resin (2) is 7-10kg/cm.

Hereinafter, the present invention will be described in detail.

Firstly, the textile sheet 1 used in the invention can be prepared by such a method that a non-woven fabric is made from a ultra fine fiber la, then is impregnated with a polyurethane resin Ib and then its surface is raised. The monofilament fineness of the ultra fine fiber la is preferably 0.001-0. 3 deniers for improving the touch.

The coating thickness of the silicon resin coated (printed) on the textile sheet 1 is preferably 0.1-2. Omm. If the coating thickness is less than 0. 1mm, the anti-slip effect is poor, and if more than 2. 0mm, the touch and strength may be degraded.

The ratio of the weight of the coated silicon resin to the overall

weight of the textile sheet is preferably 5-20%. If the weight ratio of the coated silicon resin is less than 5%, the anti-slip effect may be degraded, and if more than 20%, the touch may be degraded.

The anti-slip textile sheet of the invention has a superior stripping strength of 7-l0kg/cm between the textile sheet 1 and the silicon resin 2.

For reference, in case of conventional anti-slip textile sheet having a silicon resin coated on a general fabric, it has a low stripping strength of 3.0-4. 0kg/cm between the general fabric 3 and the silicon resin 2. The reason of which is that, if the silicon resin is coated on the general fabric, only the adhesive strength between the fabric surface and the silicon resin surface exists.

However, according to the present invention, if the silicon resin is coated on the textile sheet 1 consisting of a portion where ultra fine fibers are interlaced and a portion where polyurethane resin is impregnated part, the adhesion force between the impregnated polyurethane resin and the silicon resin and the adhesion force between the ultra fine fiber raised on the surface and the silicon resin, as well as the adhesion strength between the textile sheet surface and the silicon resin surface, work together to thus improve the stripping strength as seen from above.

In the present invention, the stripping strength was measured by the KS K 0533-1984 method. In this case, a stripping phenomenon occurs as, not the interface between the textile sheet 1 and the silicon resin is stripped off, but the textile sheet 1 itself ruptures.

In addition, the anti-slip textile sheet of the invention has an

excellent abrasion strength of more than 3,500 times measured by the ASTM D 3884-92 method. As mentioned above, the reason of which is the same as the principle (mechanism) in which the stripping strength of the anti-slip textile sheet is improved.

For reference, in case of the conventional anti-slip textile sheet having a silicon resin coated on a general fabric, it has a low abrasion strength of 500 times measured by the ASTM D 3884-92 method.

In the present invention, the abrasion strength was measured by the ASTM D 3884-92 method. Specifically, the abrasion strength is the value obtained by spinning a H-18 type abrasive wheel under a load of 500 g in a state of contacting the anti-slip textile sheet of the invention and measuring the spinning number of the abrasive wheel until the coated silicon resin 2 is removed from the textile sheet 1.

The anti-slip textile sheet of the invention can be prepared in such a manner that a silicon resin with a viscosity of 100-800 poises is partially printed and dried on the surface of the textile sheet 1 using (i) a silicon resin printing roller 4, (ii) a gravure roller 11 or (iii) a printing plate 6, the textile sheet 1 consisting of an inside having the portions where ultra fine fibers la are interlaced with each other and the portions where polyurethane resin lb is impregnated, both portions being irregularly repeated, and a surface on which the ultra fine fibers la are raised.

At this time, if the viscosity of the silicon resin is higher than the above range, the silicon resin is not extruded well, and if lower than the above range, the printed silicon resin is deformed during the procedure or

too much saturated into the textile sheet.

Firstly, the method of using the silicon resin printing roller 4 will be described concretely. The silicon resin printing roller 4 is hollow inside and has holes 4a perforated on the surface in a predetermined pattern and a printing gauge 4b mounted in the lengthwise direction.

At this time, the thickness (t) of a metal plate is preferably 0. 1-1. Omm.

If the thickness of the metal plate is less than the above range, the resin coating effect is small, and if more than the above range, its shape becomes irregular.

Fig 3 is a schematic view showing a process of printing a silicon resin on the textile sheet 1 using the silicon resin printing roller. The silicon resin fed into the printing roller is extruded into the holes formed on the surface of the roller and is partially coated (printed) on the textile sheet.

Upon printing the silicon resin on the textile sheet 1, it is preferable that the pressure is 5-8kg/cm2 and the speed is 2-5m/min. If the printing pressure is higher than the above range, a pattern blotting phenomenon may occur, and if lower than the above range, the resin may not be printed well.

After printing the resin, namely, after partially coating the silicon resin 2 on the textile sheet 1, the coated textile sheet 1 is dried for 2-10 minutes at a temperature of 80-150°C. if the drying temperature and drying time is more than the above range, an excessive cross directional shrinkage may occur to thus degrade the appearance, and if the drying temperature and drying time is less than the above range, the printed resin

may not be sufficiently dried.

Next, the method of using the gravure roller 11 will be described concretely.

The gravure roller 11 is a cylindrical roller having 0.1-0. 3mm concave grooves on the surface. The viscosity of silicon is set to 100-800 poises as mentioned above. If the depth of the concave groove is less than O. lmm, the coating layer is made thin to thus decrease the anti-slip effect, and if more than 0.3mm, the manufacture of the roller is made difficult.

Fig 4 is a schematic view showing a process of printing the silicon resin on the textile sheet 1 using the gravure roller 11 in a continuous procedure.

The silicon resin 2 is saturated into the concave grooves of the spinning gravure roller 11 and thereafter is coated on the continuously conveying textile sheet 1 in a dot pattern. At this time, a knife 13 serves to remove the silicon resin stuck on the surface of the gravure roller 11.

At this time, the coating speed is preferably 4-10m/min.

After printing the resin, namely, after coating the silicon resin 2 on the textile sheet 1 in a discontinuous dot pattern, the coated textile sheet 1 is dried for 2-5 minutes at a temperature of 110-140°C. if the drying temperature and drying time is more than the above range, an excessive cross directional shrinkage may occur to thus degrade the appearance, and if the drying temperature and drying time is less than the above range, the printed resin may not be sufficiently dried.

Next, the method of using the printing plate 6 will be described

concretely.

The printing plate 6 is formed from a silk screen with a predetermined pattern. The thickness of the printing plate 6 is preferably 0. 1-l. Omm. If the thickness is less than 0. lmm, the coating layer is made thin to thus decrease the anti-slip effect, and if more than l. Omm, the printed shape may be irregular.

Fig 5 is a schematic view showing a process of printing the silicon resin on the textile sheet 1 using the printing plate 6 in a discontinuous procedure, in which the printing plate is put on the textile sheet 1, the silicon resin is poured into the printing plate and then printed.

Upon printing the silicon resin on the textile sheet 1, it is preferable that the pressure is 5-8kg/cm2 and the speed is 2-7m/min. If the printing pressure is higher than the above range, a pattern blotting may occur, and if lower than the above range, the resin may not be printed well.

After printing the resin, namely, after partially coating the silicon resin 2 on the textile sheet 1, the coated textile sheetl is dried for 2-10 minutes at a temperature of 80-150°C. if the drying temperature and drying time is more than the above range, an excessive cross directional shrinkage may occur to thus degrade the appearance, and if the drying temperature and drying time is less than the above range, the printed resin may not be sufficiently dried.
