随着纺织品制造和处理速度的提高，水污染、微塑料污染物浓度和温室气体排放对健康和环境的影响也在增加。美国每年丢弃超过1540万吨纺织品，回收不到15%，其余的送往垃圾填埋场和焚烧炉。纺织品再利用不足以缓解这种情况；回收利用是必要的。过去几十年来的大多数纺织品回收技术都很昂贵，产出质量低，或者不能在行业内推广。为了生存，纺织品回收系统的设计必须随着充满活力的纺织和时尚业的快速发展而发展。对于任何可持续的设计，它还必须灵活地适应技术、用户、社会和环境条件的进步。为此，比较了灵活和可持续的设计原则：重叠原则被结合起来，缺失的原则被添加，以创建12个涵盖可持续性和灵活性设计的总体原则(DfSFlex)。纤维碎纸机的设计和制造以灵活性和可持续性为目标，并根据其满足DfSFlex原则的程度进行评估。对纤维碎纸机性能的评估发现，更高的速度和加工时间增加了所需输出-纤维和纱线-的生成，体现了设计中的分离设计原则，并促进了加工中的资源回收。随着这项技术的发展，随着可持续和灵活设计的应用，使用机械系统的纤维到纤维回收在重新调整纺织品用途的同时显示出很好的保值能力。
As rates of textile manufacturing and disposal escalate, the ramifications to health and the environment through water pollution, microplastic contaminant concentrations, and greenhouse gas emissions increase. Discarding over 15.4 million tons of textiles each year, the U.S. recycles less than 15%, sending the remainder to landfills and incinerators. Textile reuse is not sufficient to de-escalate the situation; recycling is necessary. Most textile recycling technologies from past decades are expensive, create low-quality outputs, or are not industry scalable. For viability, textile recycling system designs must evolve with the rapid pace of a dynamic textile and fashion industry. For any design to be sustainable, it must also be flexible to adapt to technological, user, societal, and environmental condition advances. To this end, flexible and sustainable design principles were compared: overlapping principles were combined and missing principles were added to create 12 overarching principles encompassing design for sustainability and flexibility (DfSFlex). The Fiber Shredder was designed and built with flexibility and sustainability as its goal and evaluated on how well it met DfSFlex principles. An evaluation of the Fiber Shredder’s performance found that increased speed and processing time increase the generation of the desired output—fibers and yarns—manifesting the principles of Design for Separation in design and Facilitate Resource Recovery in processing. The development of this technology, with the application of sustainable and flexible design, fiber-to-fiber recycling using mechanical systems appears promising for maintaining value while repurposing textiles.
