KR-102963380-B1 - Method for manufacturing pleated fabric recycled from waste banners and product using the same

Abstract

The present invention relates to a recycled pleated fabric made from recycled waste banners. By subjecting waste banners to washing, dyeing, and wrinkle processing steps using heat and pressure, the invention forms intaglio and relief wrinkle structures on the surface of the fabric, thereby enabling the expression of visual three-dimensionality and textural changes resulting from light reflection. Accordingly, the invention effectively improves the color non-uniformity, low saturation, and appearance degradation caused by black text that were issues in conventional waste banner recycling processes, and provides a recycled pleated fabric with excellent aesthetics and durability. Furthermore, the pleated fabric produced by the manufacturing method of the present invention can be utilized as a material for various upcycling products such as bags, wallets, shoes, and clothing.

Description

Method for manufacturing pleated fabric recycled from waste banners and product using the same The present invention relates to a method for manufacturing a wrinkled fabric made from recycled waste banners and a product using the same, and more specifically, to a method for manufacturing a wrinkled fabric made from recycled waste banners with improved aesthetics and a product using the same. Local governments and advertising agencies produce and use large quantities of banners for events, promotions, and political purposes; however, most of these banners are discarded once their usage period ends. Banners have a composite structure consisting of a 'base fabric' made of polyester, a 'coating layer' of polyvinyl chloride (PVC), and a 'printing layer' with applied ink. In other words, as a composite material made of polyester fabric coated with PVC, banners cannot be recycled through thermal melting, and there are issues regarding environmental pollution caused by the release of toxic substances during the incineration process upon disposal. To address these issues, recent attempts have been made to collect discarded banners and recycle them into bags, clothing, and construction materials (Fig. 1). However, as shown in Fig. 1, most conventional discarded banner recycling technologies have remained at the level of simply washing, cutting, and sewing the banner fabric to produce products. This method involves recycling by merely modifying the shape while maintaining the original design or color of the discarded banner, which has resulted in quality issues such as powder leakage when using products made from recycled banner fabric. Additionally, there is a limitation in that uniform processing is difficult due to the uneven design and color of the discarded banner fabric. Ultimately, conventional banner recycling technology had a problem in that the quality, color, and design of the recycled fabric were inconsistent, making it unsuitable for use as a material for upcycled products (bags, shoes, clothing, etc.). To resolve this, discarded banners must be processed into a single colored fabric by applying dye to erase the existing image, but the development of technology to realize this is currently insufficient. For example, when attempting to reuse printed fabric from discarded banners by washing and dyeing it, a problem arises where the printed layer on the surface—particularly the black ink layer containing text—remains unchanged and does not fade during the dyeing process. This is because even if colored dyes are applied over the black text, they cannot completely cover the black color. Consequently, the text or images from the printed layer remain after dyeing, making it difficult to obtain colored fabric with a uniform hue. However, while dyeing the entire fabric with black dye yields a uniform black material, the range of applications is limited due to the lack of design diversity. Therefore, there is a need to develop new technology that can recycle discarded banners into design materials that are aesthetically pleasing and highly preferred by consumers. Figure 1 is a photograph of a bag made from recycled waste banners according to the prior art, where the left side is a photograph of a waste banner that has been used up, and the right side is a photograph showing a bag made by sewing the waste banners. Figure 2 is a photograph of the recycled banner pleated fabric of the present invention. Figure 3 is a photograph of a bag made using the pleated fabric of the present invention. Since discarded banners consist of a mixture of various colors, they must be processed into a single colored fabric by applying dye to eliminate their raw appearance. While applying black dye produces a single black fabric, the applications of black are limited. Therefore, manufacturing colored fabrics by applying chromatic dyes, such as red or blue tones, is more advantageous in terms of design diversity and business viability. However, applying chromatic materials—whether red or blue—over existing colors inevitably lowers the fabric's saturation due to color overlap, giving the overall impression of a dullness. Consequently, such low-saturation fabrics are bound to be less preferred by consumers. Meanwhile, in the case of a pleated fabric, the ridges and peaks are formed alternately, and the light and dark colors naturally alternate depending on the reflection of light. In this invention, we conceived that the problem of dullness caused by low saturation, which is inevitable when reprocessing waste banners into fabric, could be overcome by processing them into a pleated fabric, and thus we processed them into a pleated fabric. As a result, it was confirmed that the mountainous parts appeared brighter than the valley parts, overcoming the dullness, and the darkness of the valley parts naturally concealed the dullness. From this, it was found that the wrinkle fabric processing of the present invention is very suitable for processi
