This study started with the cognition of problem that design activities closely related to industries could cause damages to the environment. The purpose of this study was to suggest a new concept of fashion design for environment using pre-consumer textile wastes which are produced in cutting process and used to be disposed in landfill sites. To achieve the purpose of this study, the literatures about fashion design for environment were reviewed, and design process including design development, producing, and presentation was performed. As a result, three fashion designs for environment using textile wastes were suggested. The results of this study were followings. Using pre-consumer textile wastes, this study suggested realistic way of fashion design for environment which is not just showing environment image, but providing practical use as well as preventing the waste of resources. Second, through constructing textile wastes, both 2-dimensional and 3-dimensional designs were possible, and unexpected effects created new value of beauty. Third, because the amount and type of pre-consumer textile wastes are unlimited, this fashion design for environment could be considered as continuous profit model.

The global fashion industry produces significant carbon emission and micro-plastics in oceans. Studies on sustainable design methods as such environmental issues in fashion are becoming intensely problematic. This study conducted a case study on 100 upcycle fashion brands to propose strategical upcycle fashion designs to compete in a sustainable fashion market. A literature review indicated that 3 types of textile wastes are generated as upcycling materials: post-producer, pre-consumer and post-consumer. Wastes are categorized together with 3 types of techniques: redesigning, reconstruction and handcrafting. This research derived 7 types of upcycle fashion designs that have the following features: to make luxury upcycle fashion products, to make sustainable grunge looks, to re-evaluate deadstocks, to recover vintage clothes, to convert waste into craft-arts, to offer solutions for damaged products, and to make zero-waste small fabric waste. The study results show that key drivers in the upcycle fashion design are the redesignability of materials and technique-related costs. This study implies that adopting appropriate design features can be a useful strategy for designers. New technologies will solve current problems and encourage them to design products in a new circular value system.

This study aimed to investigate the efficacy of eco-friendly leather dyeing by utilizing food wastes. Natural dyeing of eel skin was attempted using onion peels which have been used commonly for natural dyeing of textile fabrics. Eel skin is a by-product from fishery processing and is used mainly for making leather products. The colorant was extracted from onion peels in boiling water, concentrated, and freeze-dried. Dyeing of eel skin was carried out to study the effects of dyeing conditions, mordant type and mordanting method on dye uptake, color change, drape stiffness and colorfastness. The optimum dyeing conditions were $60^{\circ}C$ of dyeing temperature, 60min of dyeing time at 1:100($H_2O$ 90%: ethanol 10%) of bath ratio. The onion peels produced yellowish color on eel skin. The pre-mordanting was effective than the post-mordanting. As a result of the drape stiffness measurement, the Fe-mordanted sample was somewhat stiffer comparing to other mordanted samples. The light fastness of the non-mordant dye was excellent in 3-4 grade. Drycleaning fastness and rubbing fastness showed excellent results, but fastness was not significantly improved by mordanting.

This study proposed a base framework for creating sustainable designs with textile production waste and unused neckties with the "design thinking" approach, which is an iterative process. It aimed to set an example of how fashion designers can plan and manage their clothing design processes in a more sustainable way by recycling textile production scraps and unused neckties into unique clothing pieces with the upcycling method. Unused neckties and upholstery scraps were turned into skirts, blouses, and dresses by using creative techniques in line with current fashion trends. In addition, the five-stage iterative design process followed was explained, and the way in which the waste textile materials gained value by being converted into unique garments was discussed in terms of the user and the designer. Through the study, it was observed that the smallest amount of textile waste can be transformed into upcycled clothing via the iterative process, and original, value-added products enjoyed by consumers can be created. In addition, it was observed that the design thinking approach improves the understanding of the context of the problem, creativity in the generation of insights and solutions, skills to materialize those solutions through iterative prototyping, and the ability to combine these factors. Promising ideas to help designers develop recycling strategies were also provided.

Ultra-fine fibers are spun by expensive fiber spinning technology using special spinnerets. Ultra-fine fibrous materials have attracted considerable attentions because of their potential applications as high performance wiping cloths, water absorbent sound proofing materials and moisture transfer sporting good. However, production expense of ultra-fine fibers is 5 to 7 times higher than general textile materials. The objective of this research is to develop cost-effective recycling process to produce multi-functional ultra-fine fibrous material in terms of the development of garnetting and carding machines for ultra-fine fibrous material waste and scrap. The efficiency of sound absorption for the recycled polyester nonwoven increased with decreasing length and thickness of component fibers, which was attributed to the reduction of air permeability. It is expected that high value and cost-effective textile products are developed using ultra-fine fibrous wastes and that sound proofing material and oil absorbent f

Porous carbons have beef used as adsorbents, filters, catalyst supports, etc. due to well-development pore structure. Porous carbons can be prepared by two different activation processes i.e. physical activation by steam or CO$_2$, and chemical activation by KOH, H$_3$PO$_4$ etc. from various raw material. Recently, agricultural wastes such as rice hulls [1], coconut shell [2-31 and straws [4] are growing interest as precursors fur porous carbons due to its easy availability and cheapness. (omitted)

Modem society has reached the level where its environmental pollution is in a critical stage, and socio-political focus has been moved onto the minimization of environmental pollution. In the fashion industry, ethical production and consumption for the global protection has become the value to aim for. The purpose of this study is to establish the concept of redesigned fashion, which is a type of designing method designed to reduce global waste, and conduct a case studies on it to analyze its patterns. Environmental-friendly redesigned fashion concept is about remaking a fashion with totally different function, using disposed and wornout items from everyday lives. It is a fashion design minimizing raw materials and reducing industrial wastes. The types of redesigned fashion may be divided into three patterns: first, there is a method to recreate collar, sleeves, cuffs, pocket and other usable pieces of old clothing to make a new one. Second method is about taking out usable parts of textile from various old clothing and make a new one with patchwork method. Third is about making a purse or fashion accessories using paper, vinyl, aluminum can or worn out leather. Fourth is about making a new artistic fashion by applying tearing, punching, fringing, mashing, and layering techniques. This study aim5 to help in spreading out and applying systematic practice of redesigned fashion for companies, and elaborate the sense of social responsibility for customers, and vitalize the fashion studies for redesigned fashion in academic sense.

본 연구에서는 음식폐기물 효소당화액을 BC생산 배지원으로 이용하여, flask정치배양과 50 L로 규모확대한 공기순환배양기에서 BC생산성을 검토하고, 생산된 BC의 제반물성을 조사하였다. 전단력을 낮추기 위해 당화액배지에 agar를 첨가하여 10 L, 50 L 공기순환배양기에서 배양한 결과, 50 L 규모로 scale-up한 반응기에서 5.64 g/L로 10 L 공기순환배양기 (5.84 g/L)에서와 동등한 BC 농도가 얻어져 BC 대량생산에 효과적인 배양방법임이 입증되었다. 50 L 규모로 확대된 공기순환배양기를 이용하는 본 배양 방법은 BC의 저비용 대량생산을 위한 효율적인 생산 방법 중 하나가 되리라 사료된다. 또한, 당화액을 배지로 하여 공기순환 방법으로 제조한 BC의 물성을 정치배양 방법으로 제조한 BC의 물성과 비교 검토한 결과, 공기순환법으로 제조하였을 때 중합도 및 역학적 성질이 약간 저하하였으나 결정성은 비슷하였으며, 배양기 용량의 대소에 따른 물성의 변화는 거의 없었다.

In this study, eco-friendly functional leather was developed by recycling wastes such as eel skin, marigold(Tagetas erecta l.), hinoki cypress(Chamaecyparis obtusa). The hot water extracts of marigold and hinoki cypress leaves were freeze-dried at $-80^{\circ}C$ to prepare colorant powder. The dyeing of eel leather with marigold was carried out to investigate the effects of dyeing conditions, mordanting on dye uptake, color, morphological change, and color fastness. Considering shrinkage of eel leather caused by dyeing, the optimum dyeing conditions were $60^{\circ}C$ of dyeing temperature and 60 min of dyeing time at 1:100 of bath ratio, and color of the dyed eel leather was Y to YR Munsell series. In order to prevent the degradation of leather from microbe, we conducted combination dyeing with marigold and hinoki cypress leave colorants. In this case, the combination dyed eel leathers showed excellent antimicrobial activity with above 99% bacterial reduction rate against S. aurieus and K. pneumoniae. It was confirmed that all of the dyed eel leathers were sufficient to meet the Korean Standard for color fastness of leather products. It can be applied practically for the development of eco-friendly functional leather by utilizing some useful active components extracted from plant resources and by recycling food wastes.
