Description

Method for forming an image on the surface of neoprene fabric and image-formed neoprene fabric

The present invention relates to a method for forming an image on the surface of a neoprene fabric and a neoprene fabric on which an image is formed by the method.

Neoprene is a trade name for synthetic rubber, also known as polychloroprene or scuba fabric. Neoprene has excellent heat resistance, chemical resistance, oil resistance, ozone resistance, and wear resistance, and is widely used in diving suits. Neoprene, produced by DuPont in the United States, is a brand name for polychloroprene, which is used as a substitute for rubber. Above all, neoprene is completely waterproof, making it an ideal material for diving suits and other equipment designed to block wet and cold environments.

Neoprene fabric is soft and stretchy, making it comfortable to wear. It is widely used as sportswear because it increases activity and provides freedom of movement when exercising. Neoprene fabric hugs the body shape well and creates a slim silhouette because it has a body-hugging effect. In addition, neoprene fabric hugs the body shape well and creates a slim silhouette because it has a body-hugging effect. In addition, neoprene fabric maintains warmth even when wet. Therefore, it is suitable for water activities such as swimming or surfing. In addition, neoprene fabric has the function of protecting the skin from the sun, and has a UV blocking effect, so the skin is exposed less than usual and does not get sunburned.

However, neoprene fabric is a synthetic rubber, so it has the disadvantage of being difficult to print patterns or designs on.

Fig. 2 is a photograph showing a neoprene surface. As shown, the neoprene fabric can use shark skin fabric. In the neoprene, microscopic pores are created in the form of cells during the foaming process, and when the cross-section is cut, the air layer is cut, so there are open-cell fabrics with open cells, and closed-cell fabrics with open cells, and shark skin fabrics that are created by pressing from upper and lower plates during production. The method for forming an image on a neoprene surface according to an embodiment of the present invention can be applied to all shark skin, open-cell, and closed-cell fabrics.

First, prepare a film in step S10. PET film can be used as the film. Print a design on the film in step S20. Fig. 3 is a photograph showing a printer used in S20 of Fig. 1. The printer can use a GTX PRO printer from BROTHER. The ink can be used for textile printing. The ink can be innobella textile ink from BROTHER.

The printer prints a graphic file corresponding to a design selected by the user onto film using textile ink. Fig. 4 is a photograph showing a film on which S20 of Fig. 1 has been completed.

In step S30, hot melt powder is applied to the surface of the film on which the design of the film paper has been printed in step S20 and then shaken off. It is preferable that the hot melt powder be DTF TPU hot melt powder. Fig. 5 is a photograph showing a film paper on which S30 of Fig. 1 has been completed. When hot melt powder is applied to the surface of the film paper on which the design of the film paper has been printed and then shaken off, the hot melt powder is attached to the design as shown in Fig. 5.

In step S40, the film paper that completed step S30 is placed in an oven and heated. The oven is heated to a temperature of 75°C to 145°C, and the film paper that completed step S30 is heated for 3 minutes at 145°C and for 6 minutes at 75°C.

In step S50, the film on which step S40 is completed is placed on a neoprene fabric on which an image is to be formed. Fig. 6 is a photograph showing a state in which a neoprene fabric on which step S50 is completed is placed on the hot press of step S60 of Fig. 1.

Next, a step of pressing with a hot press of step S60 is performed. In step S50, the neoprene with the film paper placed on it is put into the hot press, paper is placed on top of the film paper, and then pressed at a temperature of 140℃ for 30 seconds. After pressing for 30 seconds, the fabric is taken out of the hot press and cooled at room temperature (S70). Fig. 7 is a photograph showing the neoprene fabric on which S70 of Fig. 1 has been completed. The design is adhered to the neoprene fabric, but the adhesion is not complete.

After cooling is complete, insert the neoprene fabric with S70 completed into the hot press, place paper on top of the film, and press at a temperature of 140℃ for 30 seconds. After pressing for 30 seconds, take the fabric out of the hot press and cool at room temperature (S90).

Figure 8 is a photograph showing the neoprene fabric on which S90 of Figure 1 has been completed. Although the design is also inserted into the gaps in the shark skin curves, there is a problem in that the image may peel off or be damaged if the surface is scratched or physical force is applied because the design is not perfectly pressed.

After cooling is complete, the film is removed so that the design is attached to the fabric and only the film can be removed. Fig. 9 is a photograph showing the state in which the film is removed from the neoprene fabric in which S90 of Fig. 1 has been completed.

Fig. 10 is a photograph showing S100 of Fig. 1. In step S100, the film is removed from the fabric where S90 is completed, then it is placed in a hot press, covered with paper and cloth, and then pressurized at a temperature of 140℃ for 10 to 15 seconds. This is the process of fixing the image.

The S100 finished fabric is cooled to complete the neoprene on which the image has been formed (S110).

In order to fix a stronger image, after completing the above step S100, a step of cooling the neoprene fabric (S110) and pressing the neoprene fabric with a hot press at a temperature of 145° C. for 40 seconds (120) may be additionally included. By adding the step S120, it is possible to prevent the image from peeling off from the neoprene or being damaged during washing.

Fig. 11 is a photograph showing neoprene on which an image has been formed according to an embodiment of the present invention. As shown, an image is stably formed even on neoprene, a synthetic rubber, and especially on shark skin, which is difficult to form an image on.

According to an embodiment of the present invention, the problem that images could not be printed on the surface of neoprene, which is a synthetic rubber, and even when some images were fixed, they peeled off severely, making it impossible to use commercially, has been solved. In neoprene, which could not form images in the past and had to form patterns by gluing different types of fabrics or sewing fabrics gluing different colors together, an image can be formed sturdily without cracking or peeling off the image and without being easily damaged, according to an embodiment of the present invention.
