Technical Field [0001] The present invention relates to a lace-type three-dimensional textile manufacturing system and a lace-type three-dimensional textile manufacturing method using the same,

The present invention relates to a three-dimensional textile manufacturing system, and more particularly, to a lace-type three-dimensional textile manufacturing system for manufacturing a three-dimensional textile of a specific race pattern made of resin using a three- And a method for manufacturing a textile.

Lace refers to an openwork fabric in which threads are tangled and tucked into a variety of non-embossed embellishments that create a net-like hole and eye on the surface. Hand lace and machine lace are classified according to the production method of lace. Needle point lace, needle-point lace, needle-point lace, needle-point lace, needle-point lace, needle-point lace, needle-point lace, bobbin lace, Bobbin lace), Crochet lace (Crochet lace), which is made by manipulating the needle by threading on the needle-shaped head using a crocheting needle, and macrame made by binding or bundling thread strands by hand It is divided into a lace (Maclame lace). In modern times, lace clothing is evaluated as high value-added product due to aesthetic effects such as transparency effect by perspective, space effect by superposition, bending effect by texture, and sensory effect by exposure.

Recently, a method of manufacturing a textile using a three-dimensional printing technique has been studied. For example, Iris van herpen, a fashion designer, has been working with the 3D printing company in Belgium since 2010 to collaborate with Materialize. The textiles produced at this time were powder-type materials output by SLS method 3D printer. And Michael Schmidt has published his work on textiles using FDM 3D printers using nylon filament materials. In addition, Yuima nakazato has manufactured and released a bike apparel with shock absorbing function by outputting to a 3D printer using SLA method using thermosetting resin. In Chanel 2015 FW, Chanel tweed fabric is reproduced, I have produced it.

However, most of the cases of textile manufacturing using 3D printing technology are industrial 3D printers. Since materials and output printers are very expensive, they are not easy to access by ordinary people, and have weak flexibility and strength. There is a problem that is difficult to be done.

In particular, when a lace-type textile is produced by a three-dimensional printing method as a textile, there is a problem that its strength is very weak and thus can not be used.

Hereinafter, a lace-type three-dimensional textile manufacturing system and a lace-type three-dimensional textile manufacturing method using the same will be described in detail with reference to the accompanying drawings. Like numbers refer to like elements throughout the drawings.

Referring to FIG. 1, the lace-based three-dimensional textile manufacturing system of the present invention includes an input unit 10 for storing a lace-shaped three-dimensional textile pattern to be manufactured, a lace-shaped three-dimensional textile A thickness controller 30 for compressing the lace-type three-dimensional textile L printed by the three-dimensional printer 20 in the thickness direction to reduce the thickness of the three-dimensional printer L, And a fabric assembling portion 40 for attaching a voile fabric V to the surface of the lace-like three-dimensional textile L whose thickness is reduced through the through-holes 30 and 30.

The input unit 10 may be constructed using a computer capable of designing a lace-shaped three-dimensional textile pattern to be manufactured through a predetermined program and storing the pattern in a file format. For example, a race-shaped 3D textile pattern is designed by repeating 1 motif (M1), 2 times (M2), and 3 times (M3) Modeled using the 123D program, and stored in the STL file format.

Further, the input unit 10 may store output conditions of a printing operation to be performed in the three-dimensional printer 20 and the like. The output conditions of the textile input through the input unit 10 include the filling of the textile, the layer height, the output speed, the nozzle temperature, the bed temperature, and the like.

The three-dimensional printer 20 can be an FDM-type three-dimensional printer that outputs a desired three-dimensional shape by discharging a filament (F) of a thermoplastic resin material while melting it. In this embodiment, the three-dimensional printer 20 melts and discharges the resin filaments on the bed while moving in the X, Y, and Z directions according to the output conditions input to the input unit 10 to output the three-dimensional textile And a control unit for controlling the operation of the nozzle 21 according to the information input from the input unit 10. [ The nozzle 21 of the three-dimensional printer 20 is provided with a heating block including a heater for heating and melting the filament.

The three-dimensional printer 20 can be constructed by applying a known FDM-type three-dimensional printer as it is, so that its detailed description will not be given.

The 3D printer 20 includes a G-code generator for converting a modeled file into a G-code file format.

The thermoplastic resin filaments used in the manufacture of textile in the three-dimensional printer 20 include acrylonitrile butadiene-styrene (ABS), nylon 12, polycarbonate (PC), polyphenylenesulfide , PPS), polylactic acid (PLA), and thermoplastic polyurethane (TPU). Since the lace-type three-dimensional textile (L) of the present invention is applied to clothing worn by a person, it is preferable to use an environment-friendly material PLA and a flexible TPU material.

The thickness control unit 30 presses the lace-type three-dimensional textile L printed by the three-dimensional printer 20 to adjust the thickness to be small. In this embodiment, the thickness control section 30 includes two pairs of pressure rollers 31 arranged vertically. A plurality of pairs of the pressure rollers 31 are arranged in the traveling direction of the lace-type three-dimensional textile L. The pairs of pressure rollers 31 are rotated in a direction opposite to each other while the pressure roller 31 disposed at the upper portion and the pressure roller 31 disposed at the lower portion are horizontally conveyed in one direction while the lace- do. A conveyor 32 for automatically horizontally conveying the lace-shaped three-dimensional textile L may be installed at the front end and the rear end of the plurality of pairs of pressure rollers 31. Therefore, when the lace-shaped three-dimensional textile L is placed on the conveyor 32, the lace-shaped three-dimensional textile L is horizontally fed in one direction, and is passed through the pressurizing rollers 31 arranged vertically, And the thickness is reduced to a desired level.

A heating unit for heating the pressure roller 31 to apply heat to the lace-shaped three-dimensional textile L when the lace-type three-dimensional textile L passes between the pressure rollers 31 of the thickness control unit 30, (Not shown). The heating unit includes a heating medium supply pipe for supplying a high-temperature heating medium through a shaft of a pressure roller 31 or an electrothermal heater installed in a shaft of a pressure roller 31, a heating chamber in which the entire pressure roller 31 is housed, Can be configured.

By controlling the thickness of the lace-type three-dimensional textile L through such heating and compression, it is possible to prevent the overall thickness increase even if the fabric V to be visible in the subsequent process is assembled.

In addition, the thickness controller 30 may function to reduce the thickness of the lace-type three-dimensional textile L, and to control the surface roughness and gloss.

The fabric assembling section 40 is formed by applying an adhesive to the surface of the lace-shaped three-dimensional textile L whose thickness is reduced, bonding a voile fabric V to the surface to which the adhesive is applied, (L) and a visible fabric (V). In this embodiment, the fabric assembling section 40 includes an adhesive injection unit 41 for spraying and applying an adhesive to the lace-type three-dimensional textile L, and a lace-type three-dimensional textile L And a pair of fusing rollers 42 which are pressed while the fabric W is passed in one direction.

The pair of pile rollers 42 are arranged in the direction of the lace-like three-dimensional textile L, The pairs of respective fusing rollers 42 rotate in the direction opposite to each other while the pressure roller 31 disposed at the upper portion and the pressure roller 31 disposed at the lower portion rotate horizontally while transporting the lace-type three-dimensional textile L in one direction, (L) and the boiled fabric (V) by means of the lace-type three-dimensional textile (L).

The voile fabric used in the fabric assembling section 40 is a fabric that is seen through and permeable as a lightweight, compact, thin fabric woven in plain weave using both warp and weft yarns.

The fabric assembling section 40 can also be applied with an environmentally friendly thermal adhesive and a laminating fusion technique, and can further perform a process of applying a color to the surface of the lace-type three-dimensional textile L after the embroidery of the fabric V is completed.

A method for manufacturing a lace-type three-dimensional textile using the lace-type three-dimensional textile manufacturing system having the above-described structure will now be described.

The design of the lace-like three-dimensional textile L to be manufactured is designed through the input unit 10, and the designed pattern is stored in a file form.

Then, a three-dimensional printer 20 is used to print a race-shaped three-dimensional textile L with a pattern of textiles stored in the input unit 10.

When the lace-type three-dimensional textile L produced by the three-dimensional printer 20 is put between the upper and lower pressing rollers 31 of the thickness control unit 30, the pressure roller 31 rotates, (L) is conveyed in one direction while compressing it in the thickness direction and simultaneously applying heat to reduce the thickness.

When the thickness of the lace-type three-dimensional textile L is reduced through the thickness control unit 30, the lace-type three-dimensional textile L is transferred to the fabric embossing unit 40, Dimensional textile (L) by spraying an adhesive. Then, the fabric (V) to be bonded is covered and bonded on the surface of the lace-type three-dimensional textile (L) on which the adhesive is sprayed. At this time, since the pressing force is not applied between the lace-type three-dimensional textile L and the boil fabric V, the bonding force between the lace-type three-dimensional textile L and the boil fabric V is small.

When the lace-type three-dimensional textile L and the boiled fabric V are padded and the lace-shaped three-dimensional textile L and the boil fabric V are put between the upper and lower plow rollers 42, The lace-type three-dimensional textile L and the boil-type textile V are pressed in the thickness direction and firmly attached to each other.

The bonded body of the lace-shaped three-dimensional textile L and the boiled fabric V which are joined together by passing through the pair of pile rollers 42 of the fabric pile assembly 40 has a tensile strength higher than that of a general lace- . The present invention will be described in detail with reference to the following examples.
