Bally Ribbon Mills Offers Prototype Development and Testing for Woven Webbings
Prototype testing critical for ensuring that new woven fabrics meet application performance requirements
To ensure that a woven webbing fabric meets the performance requirements of an application in particular environmental conditions, it is critical that all are prototyped and tested.
Often developers use an Internet search to match up their application performance requirements to an available solution that meets established fiber performance and chemistry criteria. However, all applications are unique – they rarely fit into a neat box. It is simply not possible to predict the performance of any particular woven material for all applications. In most cases, customers want prototypes to blow apart and model through observation rather than benchtop studies.
At BRM, all projects are prototyped and tested for the application – whether BRM has off the shelf fabrics or develops a new fabric. The process begins with communication between the customer and BRM to understand the application. The customer may show drawings and BRM shares relevant test report information.
Then it is time for the prototype stage. Most customers start off wanting to save time and money by incorporating an existing off the shelf fabric into their development process. BRM might send a customer several materials that are close to one another but different in some way. The customer then tests the prototypes for actual application performance with regard to thickness, tensile strength, and the effects of UV or saltwater.
When the project cannot use an off the shelf item, BRM uses a careful iterative process to come up with new fabric prototypes. When benchtop analysis to eliminate variables has been exhausted, application experts determine which variables have not been eliminated. Then weaving experts go to the loom and weave a new fabric, using the ideas collected on potential changes in the loom. It is not an exact science – customers know that they will not know how the fabric will actually perform until it has been blown apart.
One recent example for the recreational climbing market was development of a stronger yet lighter material for use in structural webbing loops used to fix gear to a climber or the mountain. To increase the strength, BRM substituted a more densely packed yarn. This changed the webbing dynamic and the internal pressure forces caused the webbing to melt on the prototype material. After conducting a forensic analysis, BRM’s application team investigated ways to modify the design to reduce the density and allow the fibers to be efficiently incorporated into the design without such high pressure. In short, iterative prototype production and testing for new applications is critical for ensuring performance of the test material relative to the application and environmental conditions in which it will operate.

BRM Finds Silver Lining in the National Pandemic Emergency
Bally Ribbon Mills has employed several innovative strategies to meet customer needs despite the many challenges that the pandemic has presented to U.S. manufacturers. A recent article in Harvard Business Review, “Why Constraints Are Good for Innovation,” describes how responding to such challenges can actually drive innovation, and BRM demonstrated this principle in 2020 by transforming its sales and manufacturing processes for an environment suddenly requiring remote office work and social distancing on the plant floor.
The new processes have achieved many benefits in efficiency and agility that have become part of the “new normal” that will outlast the pandemic. For example, BRM needed to migrate its paper-based project planning, control and feasibility (PPCF) process to an online system that could be accessed by employees working remotely. The paper process had offered limited visibility to team members not directly involved with the project, and the flow would be temporarily blocked whenever a stakeholder was traveling or on vacation and could not move the paper to the next stage of the process.
The new online system has many benefits, including allowing the project initiator to continually monitor progress and address any delays and to reroute the flow to accommodate staffing availability changes. The online system has reduced the time to complete the process by as much as 80%!
This enhanced efficiency enabled BRM to quickly develop a new structural polyester tie-down for temporary medical and first-responder structures during the pandemic, even though the order came shortly after BRM had ceased normal operations and the entire sales, customer service, and R&D teams had begun working from home.

What is limiting the widespread adoption of smart textiles?
For over two decades, the potential for smart textiles has excited the imagination — from wearables that integrate electronics to monitor health and fitness as well as diagnose medical problems, to embedded stress and strain sensors that measure data and monitor changes, to predict potential catastrophic failure in the oil and gas industry, to antibacterial and antiviral yarns and finishes that reduce COVID-19 transmission in medical and public transportation applications.
The demand exists, and the technology is feasible, and the manufacturing processes are maturing, and yet the commercial potential has yet to be realized. Bally Ribbon Mills (BRM) is playing a leading role in the industry in understanding the obstacles and implementing strategic initiatives to mitigate them.
A fundamental problem is that it is often not economically viable for individual applications to bear the financial burden of developing and refining fundamental technological advancements. BRM addresses this challenge in a number of ways.
When possible, we use well-established existing technologies and manufacturing methods, as well as the experience we have acquired over the years, in order to shorten the R&D cycle. In addition, BRM has made significant investments in the advancement of generic, horizontal product capabilities and manufacturing methods that can be utilized by diverse vertical applications, effectively sharing the development costs and further shortening the R&D cycle.
We understand the ancillary requirements to make these high-leverage strategies successful. Before embarking on projects, BRM believes that it is critically important to establish clear Intellectual Property agreements to protect all parties. We also understand that industry standardization is necessary to allow our partners to take full advantage of existing and evolving technologies, and we continue to play a leading role in the efforts to institute common industry terminology, metrics, and standards in areas such as verifying and validating conductive element properties, assessing and measuring washability, and measuring durability and wear.

Bally Ribbon Mill’s Biomedical Textile Structures Technology
Since the mid-1960s, Bally Ribbon Mills has woven straight, tapered, flared, and bifurcated biomedical textiles, always meeting the stringent standards of regulation and market demand. All BRM woven biomedical textile structures possess the following characteristics:
• Controlled permeability/porosity
• Dimensional stability
• Low elongation (unlike knitted products)
• High tensile strength in both directions
• High burst strength
• High suture retention strength
• High abrasion and friction resistance
The FDA classifies medical devices as Class I, Class II, and Class III by the risks to the patient and / or the user and the intended use of the device. Those with high risk, classified as Class III, usually sustain or support life, are implanted, or present a potential unreasonable risk of illness or injury. Examples are implantable pace makers, stents, and vascular grafts. Many of these biomedical textile structures’ characteristics are prerequisites for use in implanted applications. Without high abrasion and friction resistance, for example, wear from internal movement could lead to malfunction and failure. Other characteristics deliver particular benefits to particular uses, such as high burst strength for vascular implants.
Of course, medical technology has evolved substantially since BRM’s first graft was woven. Today, BRM offers a range of constructions and fibers to deliver a wide range of characteristics to meet consumer demands.
Loom and Weaving Technology
BRM’s biomedical textile structures are made by weaving. Although BRM operates many different types of looms, all medical products are produced with shuttle looms. These looms use a boat-shaped device to carry filling (horizontal) yarns across the vertical yarns. This technique enables BRM to create perfect tubes, bifurcate tubes, tapered or flared tubes, and biomedical structures of special shapes.
Advancements in shuttle loom technology include the incorporation of electronic components and jacquard capabilities (a system of weaving that utilizes a highly versatile pattern mechanism to permit the production of large, intricate designs and shapes). Recently, BRM has updated its biomedical weaving capabilities with an automated shuttle loom with multiple shuttles. With this capacity BRM experts can make bifurcate grafts without any hole at the crotch and use more than one filling if needed in the same graft. BRM’s design teams have the necessary backgrounds and experience to skillfully design, engineer, and develop biomedical structures as per customer needs and performance criteria.
Yarn and Material Technologies
Absorbability is key for some biomedical structure applications, but for others non-absorbability is just as critical. Fiber material is the primary factor determining this and other capabilities.
BRM has the experience to manufacture biomedical structures with monofilament, multifilaments, hybrid fiber (that include more than one type of fiber), and metallic wire designs.
In the ‘80s and ‘90s, heavier denier polyester such as 70 denier was the industry standard. Now, many customers require the use of finer denier polyester because it is comparatively easy to deploy grafts made of fine denier fibers by catheterization. BRM has the experience, expertise, and equipment to weave the finest fibers, including 10 denier polyester.
The BRM Clean Room
All Class III medical devices must be manufactured in a tightly-controlled clean room environment due to risks associated with such devices. At BRM, all medical products are manufactured in a Class 8 certified clean room, including all aspects of weaving from making a beam and making a quill. BRM’s quality control professionals also conduct in-process and final inspections inside the clean room. With this manufacturing environment and our rigorous quality control processes, BRM is ISO 13485 certified for the design and manufacture of textile components for medical devices.
Utilizing 3-D woven composite structures in place of traditional metal or 2-D laminated composites can provide cost savings through both the manufacturing process and a product’s operational lifetime. In this blog, we’ll answer some basic questions about the emerging technology – and why it’s useful for a wide variety of applications
What allows 3-D weaving to produce strong, complex, single-piece structures?
Most fabrics are woven in two dimensions – the X axis (length) and the Y axis (width) – but 3-D woven fabrics include weaving through the thickness, or the Z axis. By contrast, 2-D composites include a number of different layers of materials artificially bonded together; these layers can come apart from each other, or delaminate. 3-D weaving produces near-net-shape composite structures that are fully interconnected by their yarn, ensuring they retain strength and reliability.
What are some of the benefits of 3-D woven composites?
In addition to the elimination of delamination, the technology’s key benefits include weight reduction, reduced crack risk, lower production time, and cost reduction.
Lightweight. 3-D woven composites are dramatically lighter than metal structures. This is particularly relevant to the aerospace industry. Every pound of weight saved from an aircraft is estimated to save the aircraft’s operator roughly $1 million in operating expenses, primarily fuel, over that aircraft’s lifetime. Smart utilization of 3-D woven composite structures in aircraft design can reduce the weight of an aircraft by up to 30 percent, resulting in considerable operational cost savings.
Low crack risk. Due to curvature limitations in the layers, many 2-D shapes have considerable gaps in joints and intersections. These spaces and pockets are often filled with resin, which can crack. 3-D woven composites, even in complex shapes, have no empty pockets, as their structural integrity extends along all three axes. Crack rates are therefore far lower.
Quick production. 2-D composite production entails a long plying process. By contrast, 3-D weaving of composite structures is simpler, faster, and more cost efficient. The difference in a 3-D loom is that weft and warp yarns are not only woven together on one plane, but one plane is woven together with the next. Aside from designing a 3-D weave, which requires highly skilled design engineers, the 3-D weaving process is fully automated, drastically reducing manufacturing time.
Low cost. Indirect cost savings result from operational cost savings, for example reduced fuel. Plus, 3-D woven composites are stronger, more resilient, and less prone to breakage than 2-D laminated composites, so they can be replaced much less often, reducing replacement and maintenance costs.
What are some uses for 3-D woven structures?
3-D woven composites including orthogonal panels, thermal protection systems, near-net-shape, and complex net shape preforms are used for the aerospace, automotive, construction, military, and safety industries. For example, carbon fiber composites replace traditional titanium components in large aircraft engines to reduce weight, as these composite components are significantly lighter than comparable components in metal.
3-D weaving has been particularly successful in advancing aviation heat shield technology. BRM has woven quartz compression pads for NASA’s Orion capsule in order to ensure structural strength during launch and heat resistance during re-entry. NASA’s Heatshield for Extreme Entry Environment Technology (HEEET) program is developing a carbon thermal protection system (TPS) for extreme entries, intended to be capable of surviving the challenging environments of Saturn or Venus.
