    Collapse all Expand all

    In recent years, a class of technical textiles known as e-textiles has emerged, revolutionizing the way we perceive and use traditional fabrics. E-textiles, or electronic textiles, integrate advanced electronics and their electrical properties into fabrics, giving birth to a new breed of self-aware materials. Equipped with internal sensing capabilities, these materials have the ability to adapt to various changing environments. This opens doors to data collection opportunities that were previously uneconomical or even impossible. For example, smart garments can monitor vital signs in medical settings or track performance metrics in sports.


    Technical embroidery plays a vital role in the development and advancement of e-textiles. Thanks to its high maneuverability, quick adaptability to intricate designs, and proven scalability, embroidered systems are increasingly being sought after to create prototypes and solutions for the rapidly expanding e-textiles market. Technical embroidery uses a combination of specific tools such as the thread take-up lever, rotary hook, and bobbin case to create precise and complex designs on textiles. The thread take-up lever ensures smooth thread feeding, while the rotary hook is essential for the lockstitch formation, and the bobbin case holds the bobbin thread in place, all crucial for achieving high-quality embroidered circuits.


     

     


    Technical embroidery opens up new possibilities in the design and manufacture of e-textiles. It allows traditional circuit boards to be mechanically mounted onto fabrics, while simultaneously creating conductive textile connections. Aspects of traditional circuit board design such as creating conductive traces can also be incorporated using technical embroidery. This is achieved by embroidering with conductive threads, which can create complex circuit patterns directly onto the fabric. Sensors can be integrated exactly where they are needed in an automated process, enhancing the functionality and user-friendliness of the final product. Conductive threads, often made from materials like silver-coated fibers or stainless steel, are key to ensuring reliable electrical pathways within the fabric.

    Moreover, with the continuous miniaturization of electrical components, there has been a resurgence of interest in mounting components onto embroidered sequins, thereby expanding design possibilities. For instance, LEDs and microcontrollers can be mounted onto sequins and then embroidered onto the fabric to create interactive and visually appealing e-textiles. This not only enhances the aesthetic appeal but also allows for advanced features such as dynamic lighting and responsive feedback in garments.


    Common Mistakes:

    • Not considering the washability and durability of e-textiles: It's crucial to ensure that the electronic components and conductive threads used can withstand washing and regular wear and tear. Use of waterproof coatings and encapsulation methods can help protect sensitive components.
    • Overlooking the comfort and flexibility of the final product: E-textiles should be comfortable to wear and flexible to accommodate movement. Careful selection of base fabrics and placement of electronic elements can improve garment comfort.
    • Failing to properly insulate conductive threads: This can lead to short circuits and malfunctions. Insulating layers or coatings can be applied to prevent unintended electrical contact.

    Technical Embroidery: An Introduction


    Overview of Technical Embroidery

    Technical embroidery refers to the integration of traditional embroidery techniques with modern digital technologies. This innovative practice has revolutionized the textile industry, particularly in the field of technical textiles and e-textiles. One of the most direct uses of technical embroidery is to quickly attach and stitch traditional printed circuit boards (PCBs) into fabric carriers.

    Stitching PCBs directly into the structure of the textile, using components such as the thread take-up lever, rotary hook, and bobbin case, reduces mechanical strains on the connectors while allowing the control and processing electronics to be physically closer to their supporting electronics. The thread take-up lever plays a crucial role in maintaining thread tension, while the rotary hook is essential for creating the lockstitch by catching the top thread. The bobbin case holds the bobbin, ensuring smooth thread delivery. This technique can have a range of benefits such as increased signal-to-noise ratio, decreased mechanical fatigue-based failure, and reduced need for additional connectors. These advantages are particularly significant in applications where reliability and durability are critical, such as in medical devices or aerospace textiles.

    Embroidering connections to boards

    Technical Embroidery in E-Textiles Manufacturing

    Technical embroidery, a modernized form of traditional embroidery, has emerged as a significant player in the e-textiles manufacturing industry. One of its key advantages lies in its ability to automatically embroider electrical connections onto a host board using various conductive threads. This innovative process paves the way for quick and efficient connection of potentially hundreds of electrical connections from a board to their fabric-hosted sensors. 

    Conductive threads, also known as e-threads, are threads coated or infused with metals or other conductive materials, allowing them to carry an electrical current. They come in a variety of thicknesses and strengths, enabling designers to choose the right thread for their specific application. Conductive threads are typically made from materials such as silver, copper, or stainless steel, which are known for their excellent conductivity and durability. The selection of thread is crucial, as it affects the electrical performance and the mechanical integrity of the textile.

    Common mistakes in this process include misalignment of connections due to improper registration of the board, incorrect thread tension, and use of inappropriate conductive thread type. Proper knowledge of the embroidery machine's functionalities, such as the thread take-up lever, rotary hook, and bobbin case, is also crucial for successful operation. The thread take-up lever ensures smooth thread flow during stitching, while the rotary hook catches the thread to form a stitch. The bobbin case holds the lower thread and must be correctly tensioned to avoid stitch defects.


     

     



    Registration of the Board and Stitching

    By carefully registering the board during its embroidery to the host fabric, the electrical connection points on the board are also registered for stitching. This precise process can allow for a single stitched board to merge data from many sensor types into a single output, enhancing the efficiency and versatility of e-textiles. This technique is especially valuable in the production of smart textiles and wearables, where multiple sensors are often integrated into a single piece of fabric. Accurate registration is critical to ensure that the conductive pathways align perfectly with the components they are meant to connect.

    The role of the embroidery machine in this process cannot be overstated. The machine's precision and speed, combined with the correct use of its components such as the needle bar, presser foot, and rotary hook, are vital for achieving accurate registration and stitching. The needle bar moves the needle up and down through the fabric, while the presser foot holds the fabric in place, allowing for consistent stitching. The rotary hook's motion is synchronized with the needle to form precise and reliable stitches.

    Embroidering traces

    Introduction to Conductive Threads in Embroidery

    Embroidery has evolved from a craft to a sophisticated technology where it is possible to integrate electronic components into textile substrates. This transformation is largely due to the development of conductive threads, which are essential for creating e-textiles and smart garments. Conductive threads are typically made from materials such as silver, stainless steel, or copper, which are known for their excellent conductivity. By using techniques such as tailored wire placement, highly conductive materials can be placed into the fabric's structure to create low resistance traces. These traces function similarly to traditional circuit boards, allowing for the seamless integration of electronic circuits into textiles.

    In this context, wire sizes ranging from AWG 10 to AWG 40 have been successfully used. The American Wire Gauge (AWG) is a standard method used in the United States and other countries to denote the diameter of electrically conducting wires. The higher the AWG number, the thinner the wire. Thus, AWG 10 wire is thicker than AWG 40 wire. Thicker wires (lower AWG numbers) are typically used for applications requiring higher current capacity, while thinner wires (higher AWG numbers) are suited for more intricate designs where flexibility and minimal bulk are crucial.


    wire placement

    Wire Coatings and Customized Wires

    Wire coatings play a crucial role in the integration of wires with textiles. Coatings such as enamel, polyurethane, or PVC are used to insulate the conductive core, ensuring that the embroidery process does not compromise the wire's functionality. These coatings prevent short circuits and protect the wire from environmental factors like moisture and abrasion, which could degrade its performance over time. The choice of coating material can also affect the wire's flexibility, making it an important consideration in design.

    Furthermore, the embroidery process allows for the use of customized wires such as multicore and multifilament wires. These wires consist of multiple conductive strands bundled together, which can carry several signals through a single conductive path, thereby enhancing the functionality of the e-textile. With current technology, up to 32 signals in a single multicore line can be run, with the capability of going much higher. This capability is particularly valuable in complex e-textile applications where multiple sensors or actuators need to be integrated into a single garment.

    Applications and Future Developments

    The integration of conductive threads and wires into textiles has paved the way for the development of smart textiles and wearables. These innovative products have applications in various fields such as healthcare, where they can be used for continuous monitoring of vital signs; sports, where they can track performance metrics; military, where they can offer enhanced communication capabilities; and fashion, where they enable interactive and dynamic designs. Future developments in this area are likely to increase the functionality of these products and reduce their cost, making them more accessible for widespread adoption. Researchers are also exploring the use of nanotechnology and advanced materials to further enhance the properties of conductive threads, such as improving their conductivity, durability, and comfort.

    Embroidered sensors

    Traditional sensors such as temperature sensors can be embroidered into a textile by using two primary methods: embroidering the host circuit board into the textile, or integrating the sensor into a fiber carrier. The first method involves using a specialized embroidery machine, where a pre-designed circuit board is stitched directly onto the fabric. This approach, while straightforward and quick, often results in a rigid and inflexible textile. To achieve this, the machine uses a digitized design, guiding the needle and thread to secure the circuit board onto the fabric. It's crucial to ensure that the thread take-up lever and rotary hook are properly synchronized to avoid thread breakage and maintain precise stitch formation.

    The second method, embroidering sensors within a fiber carrier, is a more complex process. Here, the sensors are embedded within the fibers themselves before the embroidery process begins. This technique can lead to a more elegant and compliant solution, creating a textile that maintains its flexibility and comfort while carrying the functionality of the sensors. It's important to note that this method requires careful consideration of the thread tension, stitch density, and design complexity to ensure the integrity and functionality of the sensor. For example, adjusting the bobbin case tension is critical to prevent puckering and to maintain the sensor's connectivity throughout the textile. Additionally, selecting the appropriate type of embroidery thread, such as conductive yarns, is essential for maintaining the electrical properties required for sensor functionality.



    However, the field of e-textiles is constantly evolving, and more form-fitting and haptic-sensitive textile-based sensors are being explored. These sensors leverage the properties of conductive fibers themselves such as large surface areas, variable resistivity, and geometric conformability. As a result, innovative solutions such as textile electrodes, stretch sensors, and sweat sensors can be reliably created. These sensors can be used in a variety of applications, ranging from wearable technology and smart clothing to healthcare and athletic performance monitoring. For instance, stretch sensors embedded in athletic wear can provide real-time feedback on muscle movements, while sweat sensors can monitor hydration levels and electrolyte balance during physical activities.

    Embroidered LED sequins

    One innovative method of functionalizing fabrics in the field of technical textiles is the incorporation of embroidered LED sequins. This process involves mounting the necessary electronics onto a traditional sequin carrier and using an industrial embroidery machine to robotically sew the LED sequins into the fabric during its creation. This method offers significant advantages over other e-textile processes, as it eliminates the need for post-process soldering or the use of additional conductive epoxies. 

    Embroidered LED sequins exemplify the integration of electronics within textile structures, creating smart textiles that can react to environmental stimuli or user interaction. This integration is achieved through the precise control of the embroidery machine, which seamlessly incorporates electronic components into the fabric. By using conductive threads, the machine establishes electrical connections between the LEDs and the power source, often a small battery pack discretely housed within the garment.

    Historically, the use of LEDs in textiles was limited due to the need for bulky wiring and separate power sources. However, with the advent of miniaturized electronics and advanced embroidery techniques, it is now possible to integrate LED sequins directly into the fabric structure, creating luminous textiles with various applications ranging from fashion and design to safety and communication.

    The evolution of this technology can be traced back to early experiments with electroluminescent wires and fiber optics, which, while innovative, lacked the flexibility and comfort required for wearable applications. Today, embroidered LEDs offer a solution that is both aesthetically pleasing and functionally robust, opening new possibilities for interactive clothing, illuminated safety gear, and dynamic display textiles.

    Robotic sewing of LED sequins

    Figure 3: Robotic sewing of LED sequins into fabric


    In this process, the embroidery machine serves as a hybrid between traditional pick and place machines, which select a component sequin off of a reel, and a sequin machine, as it stitches the component into the fabric’s structure. This represents a significant advancement in the field of e-textiles, combining the precision of automated machinery with the versatility of traditional embroidery techniques.

    It's important to note that the quality of the final product is highly dependent on the machine settings, especially the thread tension, thread take-up lever, rotary hook, and bobbin case settings. These must be finely tuned to ensure consistent stitching and proper placement of the LED sequins.

    The thread take-up lever is crucial as it ensures that the thread is correctly fed through the needle, preventing slack that could lead to uneven stitching or thread breakage. Similarly, the rotary hook, which captures the needle thread to form a stitch, must be precisely aligned to avoid skipped stitches. The bobbin case, holding the lower thread, must maintain consistent tension to ensure balanced stitching with the top thread.

    Common mistakes include incorrect threading, improper tension settings, and misalignment of the LED components, all of which can lead to functional failures or aesthetic defects. Therefore, regular machine maintenance and calibration are essential for optimal performance.

    Electromagnetic Shielding

    Embroidery, a technique traditionally known for its decorative applications, has found a critical role in the world of technical textiles, specifically in the creation of intricate electromagnetic interference (EMI) shielding. EMI shielding is a crucial aspect of electronic device design, preventing unwanted electromagnetic signals from causing disruption or damage. The embroidery method allows for frequency-selective shielding to be produced quickly and accurately. This is achieved by changing the patterns of the embroidered conductive traces, where different signals can be blocked or allowed to pass through the technical textile. In an era of increasing digital connectivity, this control of signal propagation becomes increasingly valuable.


    This is an example of a two-layer stack-up of wire creating a box-type electromagnetic shield. The complex pattern intricately embroidered allows for specific frequencies to be selectively blocked. The use of a bobbin case and rotary hook in the embroidery machine ensures precise placement of conductive threads, which is critical for achieving the desired shielding effectiveness.



    This graph displays the areas of frequency-selective shielding effectiveness. The peaks represent the frequencies where the shielding is most effective. Adjusting the tension and thread take-up lever on the embroidery machine can influence these peaks by altering the density and pattern of the conductive traces.



    Apart from metallic wires, carbon fiber can also be used as a shielding material due to its orthotropic electrical properties, which allow it to conduct electricity in certain directions better than others. This directional conductivity is key in designing textiles that need to manage electromagnetic waves effectively across different axes.



    The shielding effectiveness of embroidered carbon fiber is similar to that of a copper shield. However, one significant advantage of using carbon fiber is the higher control over its thickness, offering more flexibility in design and application. This flexibility is particularly beneficial in applications like wearable technology, where comfort and adaptability are as important as functionality.


    For a deeper understanding of this topic, refer to the following study:

    Electronics manufacturing and scalability

    One of the key considerations when evaluating an e-textile prototype is its scalability. This refers to the ability to increase production volume quickly and cost-effectively. In the context of e-textiles, small batch manufacturing solutions can produce less than 500 parts per day. This is achievable depending on the size and complexity of the design, using a single head roll2roll machine.

    With this type of machine, a roll of fabric is inserted into the front of the machine. The fabric is then automatically pulled through the machine, where it undergoes the embroidery process. This process involves the precise movement of the fabric under the needle, orchestrated by components such as the thread take-up lever and rotary hook, which ensure consistent stitching. After embroidering, the fabric is fed to a feeder roll located at the back of the machine for collection. The single head roll2roll machine is a marvel of modern textile technology, seamlessly integrating traditional embroidery techniques with automated processing. Such machines are crucial for applications requiring high precision and repeatability, such as in the production of sensors and conductive pathways in smart textiles.

    Single Head Roll2Roll Machine

    JGW Single Head Roll2Roll Machine for Small Batch Manufacturing


    Embroidery, being a time-honored textile process, comes with a wide array of production machine configurations. This robustness significantly reduces the risk associated with scaling up production, especially when compared to newer, less-established e-textile processes. Fully automatic and scalable roll to roll solutions exist and are heavily utilized in industries such as car seat heating, where conductive threads are embroidered to create heating elements, and other technical textile sectors like medical textiles for monitoring health parameters.

    Roll to roll solution

    Interestingly, many traditional embroidery companies can adapt their existing equipment setup to transition their production from traditional embroidery to technical e-textiles embroidery. This adaptability is facilitated by the modular design of embroidery machines, which often allows for the integration of additional components such as sensors and actuators needed for e-textile applications. This is a testament to the flexibility and adaptability of embroidery technology in the face of evolving textile needs. For example, the bobbin case, a critical component in maintaining thread tension, can be adjusted to accommodate conductive threads, which may have different properties compared to standard embroidery threads.
