Project Description

Disruptive technologies, such as 3D printing, could redefine how we construct garments in the future. HBI is looking to answer the question “How can 3D printing be utilized for garment manufacturing”? 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.

Project Description

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.

Project Description

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.

Project Description

Auxetics materials have a negative Poisson’s 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’s 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.

Project Description

Biomimicry emulates nature’s patterns and strategies toward the use in man-made applications. HBI is seeking ways to incorporate biomimicry designs to enable a ‘function without finish’ 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.

Project Description

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:

  • The textile engineering/technology team will develop a test platform that accurately correlates canine bite pressure within the system, understand the nuances of force/pressure dissipation within the system and incorporate the appropriate sensors into a commercially available sleeve.
  • The electrical engineering team will be tasked with evaluating force sensors that can withstand the impact of a working dog’s bite, as well as accurately record the force of the working dog’s bite. The team will also develop a ruggedized wireless system for data transfer, create a web application that obtains, stores and displays bite profile data from in real time. The ultimate goal allows trainers to view bite profile data via a handheld device in real time.

Project Description

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 ‘unskilled’ 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.

Project Description

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 “puffer jacket”. This team will perform a manufacturing feasibility which will include determining the best way to “manage” or “control” 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 “loading” 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 “Lifestyle” 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.

Project Description

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’s absorbent exterior allows the garment’s 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.

Project Description

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 “be seen” by passing cars and must “see” 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.

Project Description

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.

Project Description

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.

Project Description

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’s landscape by developing nonwoven, reusable products. There’s 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.

Project Description

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’s 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.

Project Description

HBI is seeking ways to incorporate wearable technology into current product lines. You are charged to monitor respiration rates on Champion athletes and relay this information to a smartphone app you design. Smartphone app should also make this information available to other health apps on the smartphone. Garments must be comfortable, perform at minimal cost, and have visual appeal. Determining a sensing method and an algorithm to reliably detect respiration under various customer environments is a key deliverable for this project. Students will conduct market research to determine the reasons respiration monitoring is advantageous for Champion consumer athletes. Respiration monitor should be developed for functionality, athletic aesthetics, visual appeal, and launderability. The smartphone app should also be developed for functionality and visual appeal. Power supply options need also be evaluated as they relate to the respiration monitor for durability, performance, rechargeability, cost, and launderability. Students must also keep in mind that the overall visual appearance of the garment is as important as the performance.

Project Description

Coronary artery disease is a very common condition affecting more than 3 million Americans each year. A progressive narrowing of the coronary arteries from the buildup of plaque occurs over years and can restrict the flow of blood to the heart muscle resulting in a heart attack. One of the most common areas that this disease occurs is localized in the left main coronary artery (LMCA). In this space, the treatment of lesions and blockages at the bifurcation point (the branching of larger vessels into smaller vessels) from the LMCA to the Left Circumflex and the Left Anterior Descending coronary arteries is of interest. One of the challenges in this particular area of anatomy is the difficulty in successfully stenting (current treatment modality) due to the complexity of the geometry.

The objective of this project is to identify and create a textile-based structure/prosthesis that addresses the complex anatomy of the left main coronary artery.  The scope of this project includes:

  • Understanding the disease state, epidemiology and current state of medical devices used to treat LMCA disease and their shortcomings
  • Developing a computational model of the left main with specific emphasis at the bifurcation point
  • Develop a textile-based product that utilizes bifurcating braid or weaving techniques from the relevant implantable biomaterials

Fabricate several working models of said textile structure and conduct ex-vivo testing to determine functionality of each prototype iteration.
