기능성 섬유를 가능하게 하는 스마트 텍스트로닉스가 최근 스마트 의류, 스마트 홈, 스마트 헬스케어 등 다양한 분야에서 활용되어 다양한 제품이 개발되고 있다. 이러한 관점에서 본 연구에서는 체계적인 참여형 디자인 방법을 기반으로 한 스마트 텍스트로닉스 제품 개발 프로세스를 제안한다. 프로세스는 심층 인터뷰와 분석의 두가지 단계로 구성되며 심층 인터뷰 단계에서는 참여자가 사용행위, 행위별 요구조건, 만족도 수준 등을 포함한 사용자 여정맵과 스케치 및 간단한 프로토타입 제작을 통한 아이디어 생성 활동을 수행한다. 이 후 분석 단계에서는 디자인 연구자가 심층 인터뷰 단계로부터 도출된 결과에 행동 패턴 분석 방법을 적용하여 핵심 특성을 도출하고 이를 기반으로 한 사용자 페르소나를 생성하고 각 페르소나의 주요 니즈를 E3 가치 체계의 가치요소와 연관시킨다. 본 연구에서는 사전 설문조사를 실시하여 스마트 텍스트로닉스 시장 파악하였으며, 제안된 방법론에 대한 검증을 위해 스마트 홈 분야에서 가장 많은 사용자와의 상호작용을 갖는 소파의 디자인 사례연구를 수행하였다.

This study presents and develops a textile type touch sensor structural design that is easy to implement. First, the design of the touch sensor circuit finds the size of the switch with the easiest finger contact and selects a structure with a long circuit with the lowest resistance value. An experiment is performed on a change in an electrostatic capacitance value that accompanies the distance on the electrode and the magnitude of the electrode area of the structure; however, the structure having the distance on the electrode and the large electrode area shows the best resistance change. The laundry assessment was conducted three times at a time and ten times at a time with an average standard deviation less than one ohm, with little change in resistance. Consequently, there were no problems with durability and performance for laundry. Finally, in the bending evaluation, the difference in resistance can be seen between 1-2 ohms and was developed as a smart wearable in the future; in addition, there was no problem as a difference in resistance can be seen between 1 and 2 ohms.

The aim of this study was to impart color to bacterial cellulose (BC) fabric using various natural plant-based dyes-namely, gardenia jasminoides, green tea, and pomegranate peel. A protein pretreatment was also applied to improve the BC fabric's dyeability and mechanical properties. The BC fabric's dyeing and mordanting conditions when using plant-based natural dyes were determined by changes in the K/S values. The dyeability of BC samples dyed with green tea or pomegranate peel improved when they were pretreated with soy protein isolate (SPI) prior to dyeing. Moreover, the SPI pretreatment was efficient in improving the BC fabric's tensile strength and flexibility. This study proposes a method for dyeing BC fabric that uses plant-based natural dyes and confirms the effects of the protein pretreatment on the fabric's dyeability and durability.

This study aimed to assess the colorizing properties of bacterial cellulose (BC) using plant-based dyes, namely spinach, beet, and banana peel, and determine the dyeing conditions of each dye based on color strength (K/S) values. Tannic acid and walnut shell powder were utilized as bio-mordants, and their effects on the dyeability of BC were compared to metallic mordants. Additionally, the type of mordant and the mordanting method were assessed according to their rubbing fastness and dry-cleaning fastness. The K/S values of the colorized and mordanted BCs were also compared to examine their mordanting conditions. Finally, the mordanting conditions for spinach, beet, and banana peel dyeing were selected as post-mordanting with tannic acid, meta-mordanting with tannic acid, and post-mordanting with walnut shell powder, respectively. Based on the results, the selected mordanting conditions improved both rubbing fastness and dry-cleaning fastness of BCs to grade 5, and the light fastness achieved grade 4-5. The tensile strength and flexibility of the dyed BCs were also enhanced and comparable to that of untreated cowhide leather.
