It is a cross-sectional view for explaining a patterned shoe upper member.

A method of manufacturing a patterned shoe upper member according to an embodiment of the present invention includes time-series steps for manufacturing a patterned shoe upper member.

On the other hand, the patterned shoe upper member manufactured by the method of manufacturing a patterned shoe upper member according to an embodiment of the present invention comprises a fabric 110, an adhesive layer 210, a printing layer 310, and a coating layer 410. Can include.

For convenience of description, in describing the method of manufacturing the shoe upper member with patterns and the shoe upper member according to embodiments of the present invention, substantially the same components are described by matching reference numerals, and repeated descriptions will be omitted.

First, a release paper having a preset size and an image having a preset shape and pattern having a size smaller than the size of the release paper are prepared (S110).

Here, the release paper may have a thickness of 100 to 120 μm, and may be made of a polyethylene terephtalate material.

If the thickness is less than 100 μm, when the pattern image is printed on the release paper in the printing layer forming step (S410), wrinkles may occur on the release paper, and thus it may be difficult to form the print layer 310.

When the thickness exceeds 120 μm, when the pattern image is printed on the release paper in the step of forming the print layer (S410), the release paper is thick and lacks flexibility, and thus deformation may occur, making it difficult to form the print layer 310.

The image is continuously repeated to generate a pattern image having a size equal to or smaller than the size of the release paper, but in which the continuous images form one layout (S210).

The step of generating the pattern image (S210) may be a step (S210) of generating a pattern image forming one layout by continuously repeating an image whose size is enlarged or reduced in proportion to the size of the shoe to which the shoe upper member is applied. .

Here, in generating the pattern image, at least one of the brightness value, contrast value, contrast value, saturation value, and color value of the pattern image according to the shoe upper member is corrected according to the user's input, and the corrected value is It may be to generate a pattern image according to (S210).

Meanwhile, in generating a pattern image, a pattern image may be generated by continuously repeating a plurality of images by providing a tolerance of a preset length between the images (S210).

It is preferable that the length of the tolerance is smaller than the smaller of the horizontal length and the vertical length of the image.

When a plurality of images are arranged in one layer to form a pattern image, it may be easier to make a plurality of shoe upper members using one image.

Accordingly, the method of manufacturing a patterned shoe upper member according to an embodiment of the present invention has an advantage of increasing manufacturing efficiency and yield in manufacturing a patterned shoe upper member.

A polyurethane resin is applied to the surface of the release paper and aged to form a coating layer 410 (S310).

When the polyurethane resin is coated on the release paper, the polyurethane particles, which are components of the pigment used to form the printing layer 310, and the polyurethane particles of the coating layer 410 interact with each other, and the coating layer 410 ) And the printing layer 310 is improved, and when the adhesive layer 210, the printing layer 310, and the coating layer 410 are sequentially stacked on the fabric 110 in the separation step (S610), the coating layer 410 is printed. The durability of the shoe upper member may be improved by protecting the printing layer 310 without being peeled off from the layer 310.

The coating layer 410 may be a layer formed on the surface of the printing layer 310.

In the coating layer forming step (S310), a polyurethane resin is applied to the surface of the release paper, and aged at 65 to 75° C. for 20 to 28 hours to form a coating layer 410 having a thickness of 24 to 36 μm.

The coating layer 410 may be a polyurethane formed on the surface of the printing layer 310 and having a thickness of 24 to 36 μm.

If the aging temperature is less than 65°C, aging may take a long time to reduce productivity, and if it exceeds 75°C, release paper or polyurethane resin may be deformed.

If the aging time is less than 20 hours, aging may not be sufficient, and if it exceeds 28 hours, further aging is meaningless, and productivity may be degraded due to a long aging time.

Coating layer forming step (S310) is a first coating layer forming step of forming a primary coating layer 411 having a thickness of 12 to 18 μm by applying a polyurethane resin to the surface of a release paper and aging at 65 to 75° C. for 20 to 28 hours. (S311) and 2 to form a secondary coating layer 412 having a thickness of 12 to 18 μm by applying the polyurethane resin to the surface of the first coating layer 411 and aging for 20 to 28 hours at 65 to 75°C. It may include a step of forming a secondary coating layer (S312).

In the case of forming the coating layer 410 having a size of 24 to 36 μm at a time, the coating layer 410 may not effectively protect the printing layer 310 because a portion of the coating layer 410 may not be formed.

When the coating layer 410 is formed by dividing into a first coating layer forming step (S311) and a second coating layer forming step (S312), a portion of the coating may be insufficient in the first coating layer forming step (S311), and the second coating layer may be formed. By coating the surface of the first coating layer 411 in step S312, the surface of the first coating layer 411 is coated, and at the same time, the coating is made on an area where the coating is insufficient, thereby preventing this.

If the thickness of the coating layer 410 is less than 24 μm, the strength of the coating layer 410 is weak, so that the printing layer 310 cannot be effectively protected, and the durability of the shoe upper member may be deteriorated.

When the thickness of the coating layer 410 exceeds 36 μm, the flexibility of the coating layer 410 is reduced, and when the shoe upper member is applied to the curved surface of the shoe, the shoe upper member may be deformed and wrinkles may occur.

Preferably, the coating layer forming step (S310) is a step of forming a primary coating layer 411 having a thickness of 12 to 18 μm by applying a polyurethane resin to the surface of the release paper and then aging at 65 to 75° C. for 20 to 28 hours.

The printing layer forming step S410 may be a step of forming the printing layer 310 by printing a pigment on the surface of the coating layer 410 at a printing layer forming speed ^{of 10 to 20 m 2 /h.}

If the print layer formation speed is ^{less than 10m 2} /h, the speed of forming the print layer 310 on the surface of the coating layer 410 may be too slow, resulting in a decrease in productivity.

If the printing layer formation speed exceeds 20m ² /h, the speed is high, and thus, insufficient printing may occur on the surface of the coating layer 410 or print quality may be degraded.

The printed layer 310 formed in the printing layer forming step S410 is dried (S510).

The printing layer drying step (S510) includes a first drying step (S511) of directly heating and drying the printed layer 310 for 55 to 65 seconds using a heating plate of 55 to 65°C, and 70 to 80 to the printed layer 310. It may include a second drying step (S512) of heating and drying by applying heat and hot air of °C for 55 to 65 seconds.

If the heating temperature is less than 55° C. in the first drying step (S511), the heating time may be lengthened and productivity may decrease.

When the temperature exceeds 65° C. in the first drying step (S511), the pigment is rapidly dried at the initial stage, and deformation such as cracking of the printed layer 310 may occur.

If the heating time is less than 55 seconds in the first drying step (S511), the heating time may be short and the printed layer 310 may not be sufficiently dried.

If the heating time exceeds 65 seconds in the first drying step (S511), the heating time may be long and productivity may decrease.

If the heating temperature in the second drying step (S512) is less than 70° C., the heating time may be lengthened and productivity may decrease.

If the heating temperature exceeds 80° C. in the second drying step S512, damage may occur to the printed layer 310 and the coating layer 410.

If the heating time is less than 55 seconds in the second drying step (S512), the heating time may be short and the printed layer 310 may not be sufficiently dried.

If the heating time exceeds 65 seconds in the second drying step (S512), the heating time may be lengthened, resulting in a decrease in productivity.

An adhesive layer 210 is formed by applying an adhesive to the surface of the coating layer 410 including the printing layer 310 (S610).

The adhesive layer 210 may be formed by applying an adhesive to the surface of the coating layer 410 including the printing layer 310.

The adhesive layer 210 may be stacked from the surface of the release paper to the surface of the fabric 110 when the release paper and the fabric are separated in the separating step (S610).

The adhesive may be made of a composition capable of adhering the coating layer 410 and the printing layer 310 and the fabric 110 without causing deformation to the coating layer 410 and the printing layer 310 and the fabric 110.

Preferably, the adhesive may be a polyurethane-based adhesive.

The fabric 110 is attached to the adhesive layer 210 (S710).

The attaching step (S710) may include attaching one side of the fabric 110 to the adhesive layer 210 and aging for 20 to 28 hours at 65 to 75°C so that the printed layer 310 is transferred to the fabric 110. have.

At this time, if the aging temperature is less than 65°C, the aging time may be lengthened and productivity may decrease, and if the aging temperature exceeds 75°C, damage may occur to the fabric 110.

If the aging time is less than 20 hours, the aging time may be short and sufficient aging may not be achieved. In addition, when the aging time exceeds 28 hours, the aging is completed, and it may be difficult to expect a further aging effect.

Next, the release paper and the fabric 110 are separated to obtain a semi-finished product laminated on one side of the fabric 110 in the order of the adhesive layer 210, the printing layer 310, and the coating layer 410 (S810).

When the release paper is separated from the fabric 110, the coating layer 410, the printing layer 310, and the adhesive layer 210 stacked on the surface of the release paper are separated from the surface of the release paper, and the adhesive layer 210, printed on the surface of the fabric 110 The layer 310 and the coating layer 410 may be sequentially stacked.

Accordingly, the patterned shoe upper member manufactured by the method of manufacturing a patterned shoe upper member according to an embodiment of the present invention is adhered to the fabric 110, the adhesive layer 210, the printing layer 310, and the coating layer 410. Since the adhesive layer 210, the printing layer 310, and the coating layer 410 are not peeled off from the fabric 110, the durability of the shoe upper member can be improved.

When the printing layer 310 and the coating layer 410 are laminated on the surface of the fabric 110 as shown in FIG. 2, the coating layer 410 protects the printing layer 310 from external influences, thereby damaging the printing layer 310. It can improve the durability of the upper member of the shoe.

The semi-finished product is cut using a cutting frame having a plurality of through holes corresponding to the shapes of the plurality of images formed on the printing layer 310 to complete the shoe upper member (S910).

The member completion step (S910) is a step of preparing a cutting frame in which a plurality of through holes corresponding to the shape and size of a plurality of images that are continuously and repeatedly arranged by placing a tolerance of a predetermined length prepared in the pattern image forming step (S210) is formed; and And seating the cutting frame to expose a plurality of images continuously and repeatedly arranged on the top of the semi-finished product, and pressing the cutting frame in the direction of the semi-finished product to separate the semi-finished product to correspond to the plurality of images.

And, heat exceeding 140° C. may cause damage to the coating layer 110, the printing layer 310, and the fabric 410.

The hot melt adhesive layer 610 may have a thickness of 100 to 150 μm.

If the thickness of the hot melt adhesive layer 610 is less than 100 μm, the thickness of the hot melt adhesive layer 610 may decrease when the shoe upper member is attached to the shoe upper. If the thickness exceeds 150 μm, the adhesive strength is sufficient. The increase in thickness is meaningless and the amount of hot melt adhesive used is large, which can increase the cost of the shoe upper member to be manufactured.

In the step of attaching the hot melt film, one protective layer 510 is removed, and the fabric 110 is pressed and attached to the exposed hot melt adhesive layer 610, so that the hot melt adhesive layer 610 and the protective layer 510 are attached to the other surface of the fabric 110. ) May be formed.

In the case of forming the coating layer 420 having a size of 24 to 36 μm at a time, the coating layer 420 may not effectively protect the printing layer 320 because a portion where the coating is insufficient may be formed.

When the coating layer 420 is formed by dividing into a first coating layer forming step (S421) and a second coating layer forming step (S422), a portion of the coating may be insufficient in the first coating layer forming step (S421), and a second coating layer may be formed. By coating the surface of the first coating layer 421 in step S422, the surface of the first coating layer 421 is coated, and at the same time, the coating is made on an area where the coating is insufficient, thereby preventing this.

If the thickness of the coating layer 420 is less than 24 μm, the strength of the coating layer 420 is weak, so that the printing layer 320 cannot be effectively protected, and durability of the shoe upper member may be deteriorated.

When the thickness of the coating layer 420 exceeds 36 μm, the flexibility of the coating layer 420 is degraded, and when the shoe upper member is applied to the curved surface of the shoe, the shoe upper member may be deformed and wrinkles may occur.

Preferably, the coating layer forming step (S420) is a step of forming a primary coating layer 421 having a thickness of 12 to 18 μm by applying a polyurethane resin to the other side of the fabric and then aging at 65 to 75° C. for 20 to 28 hours.
