Disruptive technologies, such as 3D printing, could redefine how we construct garments in the future. HBI is looking to answer the question \u201cHow can 3D printing be utilized for garment manufacturing\u201d? The goal of this project is to develop applications\/products\/concepts that utilize 3D printing of a full garment or on a textile backing (compatible with nylon\/spandex and\/or polyester fibers) used in trims or portions of a garment. The team will explore opportunities to the 3D print directly on textiles for innovative garment designs, establishing the pros & cons of the technology as compared to standard textile processing, and in doing so will identify the potential barriers of 3D printing for manufacturing garments. The team will generate a finished concept garment that upholds to the comfort and durable integrity of the intended garment.<\/p>\n<\/div><\/div><\/div>\n\n\n\n

By 2025 synthetic production is expected to reach 84 million metric tons, equivalent to 798 million kg CO2 emissions (US polyester production). Moreover, 80% of the clothing we throw away ends up in landfill. The objective of this design project is to explore alternatives to the synthetic materials that have the same properties as the polyamide \/ elastane blends and polyamide \/ spandex blends that are used in swimwear produced by Li & Fung America. This team will not only consider material content but also new ways of spinning that create stretch, fabric construction techniques that maximize stretch and retention. The team will consider factors such as scalability and market price, as well as the sustainability of the material developed.<\/p>\n<\/div><\/div><\/div>\n\n\n\n

Kaneka Corporation, a large Japan based producer of synthetic fibers, is developing a biodegradable fiber intended for use in both aerobic and anaerobic environments. This fiber, tentatively identified as PHBH (a copolymer comprised of 3-hydroxybutyrate and 3-hydroxyhexanoate), is an aliphatic polyester biopolymer. Kaneka Corporation is a committed advocate for both the remediation and preservation of the environment and feels that the PHBH fiber may make a significant contribution to the betterment of our world. The objective of this project is to investigate the range of potential applications for PHBH fiber in both aerobic (soil: e.g., agricultural) and anaerobic (seawater: e.g., fishery) environments. We would also like to use the information obtained to formulate an initial market strategy, ideally working with downstream partners to develop functional prototypes using the PHBH fiber.<\/p>\n<\/div><\/div><\/div>\n\n\n\n

Auxetics materials have a negative Poisson\u2019s ratio that when stretched, become thicker perpendicular to the applied force. Auxetics can be illustrated with an inelastic string wound around an elastic cord. When the ends of the structure are pulled apart, the inelastic string straightens while the elastic cord stretches and winds around it, increasing the structure\u2019s effective volume. Applications in auxetic materials have been demonstrated for shock absorption in military applications and athletic shoes. The objective of this project is to develop an lightweight (<130 gsm) innovative garment product that benefits from the use of an auxetic structure (in yarn or textile form). The goal is for the fabric to provide more coverage (or at least no sheerness) when stretched. The prototype should include testing strategies for the evaluation of this bi-axial properties of the auxetic property.<\/p>\n<\/div><\/div><\/div>\n\n\n\n

Biomimicry emulates nature\u2019s patterns and strategies toward the use in man-made applications. HBI is seeking ways to incorporate biomimicry designs to enable a \u2018function without finish\u2019 approach to existing fabric technologies. What solutions can be found in nature and be applied to this concept? Think of plants, animals, marine life, insects that have protective yet functional elements. The objective of this project is to identify a non-chemical solution that provides added benefits to a garment or fabric by creating an innovative structure in fiber (spinning), knitting, weaving, etc. that is bio-inspired. The finished fabric\/garment should be appealing to consumers and be machine washable.<\/p>\n<\/div><\/div><\/div>\n\n\n\n

Working dogs play an integral role in the day to day operations of both military soldiers and law enforcement officers worldwide. All canine handlers and trainers use protective bite sleeves for engagement and apprehension training. However, the canine bite sleeves on the market today fail to measure the bite force of the working dog. The result is that trainers must rely on years of training experience to subjectively evaluate their canines which may result in ineffective training, canine\/handler injury or unsafe environments during operations. The development of the canine bite force sleeve would help provide an objective measurement tool for trainers to more thoroughly understand canine bite dynamics. The objective of the project is to re-design a commercial bite sleeve by incorporating electronic (or other) pressure sensors within the sleeve that accurately measures, records, and displays bite force data in real time. Canine bite profile includes overall bite pressure, mapping the bite print and duration of a bite. This project will collaborate with a Senior Design team in Electrical and Computer Engineering in the following tasks:<\/p>\n\n\n\n

Incredible technological innovation has been delivered to every part of the apparel manufacturing process in the last 20 years with the exception of the garment assembly phase. Farming, yarn-spinning, knitting and dyeing operations, which are all very capital intensive and typically require very little labor, have benefitted from tremendous innovation and new technologies. The garment assembly (sewing) is a critical part of the process in manufacturing good quality apparel, but has been left behind in the innovation process until just recently. While the workers in sewing facilities are often referred to as \u2018unskilled\u2019 at Gildan we believe these people are our most important resource and therefore are interested in doing a deep dive into all aspects of the sewing operations. This project will examine the complete workflow within these operations, including material movement, human and equipment positioning and physical locations, to best optimize productivity and reduce the physical strains of their repetitive workload. The findings of this project can lead to significant innovation in equipment and process improvements across the industry and the improvement of the lives of the workers.<\/p>\n<\/div><\/div><\/div>\n\n\n\n

The goal of this project is to create a commercial, performance-driven nonwoven insulation that incorporates down waste (short fibers leftover from the processing of down which typically go to the landfill). The nonwoven insulation to-be created will be the internal insulation component of a conventional quilted \u201cpuffer jacket\u201d. This team will perform a manufacturing feasibility which will include determining the best way to \u201cmanage\u201d or \u201ccontrol\u201d the down in a facility and incorporate it consistently and durably in a non-woven web. The team will also seek to determine the min-and-max amount of down \u201cloading\u201d to achieve desired manufacturing parameters (i.e. speed\/output\/wastage\/etc) as well as desired performance parameters. Finally, the team will develop a puffer jacket prototype from a \u201cLifestyle\u201d perspective that would be ideal to have this insulation as a primary component. In doing so, marketing concepts will be developed that highlight the sustainability aspect of this initiative in addition to the potential performance gains compared to either (or both) down and non-down insulation systems.<\/p>\n<\/div><\/div><\/div>\n\n\n\n

Develop a polyester fabric with moisture-wicking properties that can be used for polo shirts and T-shirts for the industrial laundry market. The team will determine moisture wicking performance (MWP) of top athletic wear as a function of wash cycles. Successful project will demonstrate continued MWP after a minimum of 50 industrial laundry cycles (wash and dry) and 75% of MWP at 100 industrial laundry cycles. Hand and weight of fabric made from yarn should be equivalent to typical consumer wear and competitive products and the solution should be manufacturable and cost-effective.<\/p>\n<\/div><\/div><\/div>\n\n\n\n
DRYV Technology<\/p>\n\n\n\n
Matt Coats, Joseph Stephens, Zack Moore<\/p>\n\n\n\n
DRYV is a patented textile technology that integrates an absorbent exterior into moisture wicking apparel, creating a more efficient method of moisture management within a garment. Developed for any activity where sweat inhibits performance, DRYV\u2019s absorbent exterior allows the garment\u2019s moisture wicking body fabric to perform its intended function, while providing the wearer with a surface area to assist in keeping hands, face and extremities dry. Historically, both the absorbent and wicking materials used in DRYV construction have been knits. As DRYV grows its list of licensed partners with products in many different categories, it is necessary to test the performance of this concept in different embodiments. Areas of particular interest include the use of woven fabrics and different methods of connecting the fabric such as lamination and bonding. The end goal of this project will be to recommend fabrics, their performance characteristics as well as constructions methods for shorts and pants that meet and optimize the DRYV standards for wicking and absorbing.<\/p>\n<\/div><\/div><\/div>\n\n\n\n

HBI is seeking innovative ways to use light in textiles for a variety of functions and designs. You are charged to light up Champion athletes who must \u201cbe seen\u201d by passing cars and must \u201csee\u201d where they are going at any time of the day or night. Garments must have high-visibility at minimal costs. The garments should maximize safety and visual appeal. Students will conduct market research to determine the reasons lighted running apparel is advantageous for consumers. Active lighting materials should be evaluated for visibility, lighting, customer functionality, aesthetics, visual appeal, and launderability. Power supply options need also be evaluated as they relate to lighting for durability, performance, rechargeability, cost, and launderability. Solutions should be easily incorporated into traditional apparel manufacturing processes as well as provide the best combination of price and performance characteristics.<\/p>\n<\/div><\/div><\/div>\n\n\n\n

Saab Barracuda is the sole-source provider of Ultra-Lightweight Camouflage Systems (ULCANS) to the U.S. Military. These net systems are used to camouflage assets in the battlefield against detection by the enemy using multispectral tactical sensors. The objective of this project is to design a fabric construction that will offer both an improved thermal signature and reduced thermal transmission. The fabric needs to physically obscure both visual and thermal assets beneath, and offer minimal thermal loading of the textile itself. Fabric must be lightweight (~2.0 osy), durable for 2 years exposure in austere environments, and ultimately be commercially produced in flat roll form at a reasonable cost. A benchmark analysis of the current SAAB Barracuda fabric constructions will be need to be performed to determine improvements for strength, and multispectral performance, as well as access to tactical sensor imaging capability and data interpretation.<\/p>\n<\/div><\/div><\/div>\n\n\n\n

Microfibers, a subcategory of microplastics, are defined as small plastic particles that are fibrous in shape and less than 5 mm in length. Our prior work has demonstrated that synthetic microfibers can be shed from garments throughout their lifetime. The goal of this design project will be to understand factors for how and why synthetic garments shed microfibers. The primary focus of the deliverables involved in the project will include a statistical analysis of the cause (yarn composition, construction, etc) and the effect (microfiber shedding through napping.brushing\/wash). In order to accomplish this analysis, the students will use a standardized testing protocol set forth by Patagonia testing engineers and environmental researchers. This will allow for any future comparative analysis with other research institutes and\/or lab studies.<\/p>\n<\/div><\/div><\/div>\n\n\n\n

Our company, Standard Textile, is a leading supplier of textile products to the US healthcare industry (think: scrubs, sheets, surgical gowns, cubicle curtains, etc.). We believe that there is a major opportunity to change the industry\u2019s landscape by developing nonwoven, reusable products. There\u2019s one catch: in order to justify the costs associated with nonwoven production, we would need to develop a single fabric that has could be used in a multitude of product lines. The objective of this project is to explore nonwoven fabrication of a greige fabric that could be used as a reusable material with strength, colorfastness, tactile hand, and appearance that could replace woven and knitted healthcare textiles. Specific healthcare products include Bedsheets\/pillowcases, Patient Gowns, and Scrubs.<\/p>\n<\/div><\/div><\/div>\n\n\n\n

V-belts are friction drive systems which rely on the wedge effect to transmit power from pulleys into the matching belt profile. Manufacturers strive to improve V-belt performance by achieving higher power transmission capability in a smaller footprint and at higher speeds. Current link belting technology has reached a point where significant development is required to increase performance in these areas. Fenner Precision\u2019s solution is PowerTwist, a special type of power transmission V-belt (link belting) that is made from polyurethane\/polyester composite links. This composite belting provides many advantages over traditional rubber V-belts such as the ability to make belts of any length, faster installation times and improved performance. The goal of this project it to demonstrate improvement in the composite architecture so as to improve flexibility, tensile strength, coefficient of friction (between belt and pulley), and prevention of pull-out. The fabric\/polymer combination will be a key to developing the next generation of link belting and Fenner Drives.<\/p>\n<\/div><\/div><\/div>\n\n\n\n
