Knitting is the intermeshing of yarns into loops that leads to the creation of fabrics. Fabrics knitted with several different yarns constitute a modern class of advanced engineering materials. Additionally, computer-controlled knitting offers great promise as a digital manufacturing technology because of the ability to make novel materials from multiple yarn types and varying loop patterns. Given the enormous flexibility of modern knitting equipment and the variety of yarn materials currently available, knitted structures can now be viewed as a versatile, programmable, multi-scale and microstructure-based engineering material system that can be designed and manufactured to meet a wide range of functional and mechanical requirements. While the current state of the art in commercial knitting technology is quite capable of designing and manufacturing a variety of materials for consumer clothing, many significant technological gaps exist that prevent knitting from becoming a general process for digital manufacturing. The critical barrier to the production of these versatile material systems is the lack of validated comprehensive design tools and accurate predictive modeling methods. This project will develop an integrated design framework that addresses these barriers in order to enable the programmable manufacturing of customized knitted materials. Developing advanced technologies in this field has the potential to create new, revitalized economic activity in an American industrial sector that has mostly known decline in recent decades. The project has several technical objectives. They are: a) the creation of a design framework that determines yarn specifications and processing commands given the performance requirements for a knitted material, b) the development of a data-driven algorithm for computing inverse mappings from low-dimensional requirements space into high-dimensional control data space that utilizes efficient nearest-neighbors search and scattered data interpolation techniques to find viable design solutions for knitted materials, c) the definition of an objective function capable of determining if knitting design requirements have been fulfilled, d) the utilization of information pathways that allow for an inverse-forward simulate-manufacture-evaluate-validate feedback loop in the design process, and e) the integration of design/simulation processes with the production, testing and evaluation of actual materials to provide an accelerated, programmable manufacturing capability for novel, customized knitted materials.

编织是将纱线融合成导致织物创造的环的循环。编织有几种不同纱线的织物构成了现代的高级工程材料。此外，由于能够从多种纱线类型和不同的环模式制造新颖的材料，因此计算机控制的编织作为数字制造技术提供了巨大的希望。鉴于现代针织设备的巨大灵活性以及当前可用的各种纱线材料，现在可以将针织结构视为一种多功能，可编程，多规模和基于微观结构的工程材料系统，可以设计和制造以满足广泛的功能和机械需求。尽管商业编织技术的当前艺术状况非常有能力设计和制造各种用于消费者服装的材料，但存在许多重要的技术差距，以防止编织成为数字制造的一般过程。这些多功能材料系统生产的关键障碍是缺乏经过验证的综合设计工具和准确的预测建模方法。该项目将开发一个集成的设计框架，该框架可以解决这些障碍，以便能够可编程的定制针织材料制造。在这一领域，发展高级技术有可能在近几十年来大多数已知的美国工业部门中创造新的，振兴的经济活动。 该项目有几个技术目标。它们是：a）创建一个设计框架，该设计框架决定了针对编织材料的性能要求，该设计框架决定了纱线规格和处理命令，b）开发数据驱动的算法，用于计算低维需求空间的逆映射到高维度的数据空间，以搜索和散布的数据插入的材料，从目的功能能够确定编织设计要求是否已满足，d）使用信息途径的利用，该信息途径允许在设计过程中进行逆向模拟 - 制造-Edaluate-valate-valate-valate-valate-valate-valate循环，以及e）设计/模拟过程的整合与生产，测试和评估的实际材料与实际材料的生产，测试和评估以提供加速，可加速的制造能力，以实现编制性，定制，定制，定制，定制，定制。
