Abstract

The present invention relates to a method for dyeing a fabric to form wrinkles and a wrinkle-dyed fabric obtained thereby. A method for wrinkle-dying a fabric according to an embodiment of the present invention comprises the steps of: preparing a fabric; twisting the fabric in one direction; introducing the fabric twisted in one direction into a chamber where dye is stored; heating the dye in the chamber to form primary wrinkles and dye; twisting the primary dyed fabric in the opposite direction to the one direction; introducing the fabric twisted in the opposite direction into the chamber; heating the dye in the chamber to form secondary wrinkles and dye; rinsing the secondary dyed fabric with water; and dewatering and drying the fabric.

Description

Method for dyeing and finishing of fabric and the fabric using the same The present invention relates to a method for dyeing wrinkles in fabric, and more particularly to a method for dyeing fabric to form wrinkles and a wrinkle-dyed fabric obtained thereby. As is well known, in the fashion industry, which is fast-paced and sensitive to trends, there are increasing instances of using fabrics dyed with wrinkle-forming dyes. Recently, these wrinkle-dyed fabrics are being released not only as clothing but also as various products for everyday use, such as bags, curtains, and wrapping cloths. Conventional wrinkle-dyed fabrics had the disadvantage of being inefficient and time-consuming because they were produced in a two-step process where wrinkles were formed first and then dyed, or dyed first and then wrinkles were formed. Many methods have been proposed for efficiently processing wrinkle dyeing on fabrics. For example, Published Patent No. 10-2004-0042346, Published Patent No. 10-2012-0006229, Published Patent No. 10-2019-0021856, Registered Patent No. 10-1417713, etc. disclose a method for processing wrinkle dyeing of fabrics. In the relevant technical field, there is a demand for a fabric wrinkle dyeing method that allows for the formation of wrinkles more effectively while creating predictable shapes, and enhances the marketability of the fabric by varying the intensity of the color dyed on the fabric. FIG. 1 is a schematic block diagram of an apparatus for carrying out a method for dyeing wrinkles of a fabric according to an embodiment of the present invention. FIG. 2 is a flowchart sequentially explaining a method for dyeing wrinkles of a fabric according to an embodiment of the present invention. FIGS. 3a and 3b are state diagrams of a fabric processed in a wrinkle dyeing method according to an embodiment of the present invention. FIG. 4 is an exemplary diagram of a fabric that has been wrinkled and dyed according to the wrinkle dyeing method of a fabric according to an embodiment of the present invention. FIG. 5 is an example illustration of a fashion item using a wrinkle-dyed fabric according to an embodiment of the present invention. Hereinafter, some embodiments of the present invention will be described in detail with reference to exemplary drawings. It should be noted that in assigning reference numerals to the components of each drawing, the same components are given the same reference numeral whenever possible, even if they are shown in different drawings. Furthermore, in describing the embodiments of the present invention, if it is determined that a detailed description of related known components or functions would hinder understanding of the embodiments of the present invention, such detailed description is omitted. FIG. 1 is a schematic block diagram of an apparatus for carrying out a method for dyeing wrinkles of a fabric according to an embodiment of the present invention. Referring to FIG. 1, a fabric wrinkle dyeing device according to an embodiment of the present invention may be configured to include a heating chamber (10), a heating device section (20), a picking device section (30), a twisting device section (40), a pulling device section (50), and a controller section (60). The chamber (10) can be formed so that an internal space (S) is formed and the top is open. The upper part of the chamber (10) that is opened by a lid (not shown) may be closed. The chamber (10) can be made of a material that can withstand heat sufficiently. A drain device (11) for discharging a liquid (e.g., dye) from the internal space (S) to the outside may be provided on the lower side of the chamber (10). The drain device (11) is equipped with a valve (not shown), and the discharge of the liquid can be controlled by the valve. Liquid dye and fabric can be introduced into the internal space (S) of the chamber (10). Optionally, additional substances such as coloring agents may be introduced. The heating device part (20) can be a device for heating the chamber (10). The heating device part (20) can be, for example, a conventional burner. The heating device part (20) can be placed at the bottom of the chamber (10). The heating device part (20) may be provided integrally with the chamber (10). The picking device part (30) can be a device for picking up fabric and feeding it into the chamber (10) or picking up fabric and taking it out from the chamber (10). The picking device part (30) may be equipped with a clamp designed to pick up fabric at the end. The twisting device part (40) can be a device for twisting the fabric in one direction. At this time, twisting the fabric in one direction means twisting it in one direction, for example, as is typically done when wringing out a towel (see Fig. 3b). The twisting device part (40) is provided with fixing parts (not shown) on both sides for fixing both ends of the fabric, and one fixing part may be configured to be rotatable in both directions. The distance between the
