Producing functional fabrics that perform all the functions we want, while retaining the characteristics of fabric we're accustomed to is no easy task. Two groups of researchers at Drexel University -- one, who is leading the development of industrial functional fabric production techniques, and the other, a pioneer in the study and application of one of the strongest, most electrically conductive super materials in use today -- believe they have a solution.

They've improved a basic element of textiles: yarn. By adding technical capabilities to the fibers that give textiles their character, fit and feel, the team has shown that it can knit new functionality into fabrics without limiting their wearability. The team reported that its conductive yarn packs more conductive material into the fibers and can be knitted by a standard industrial knitting machine to produce a textile with top-notch electrical performance capabilities.

This combination of ability and durability stands apart from the rest of the functional fabric field today. Most attempts to turn textiles into wearable technology use stiff metallic fibers that alter the texture and physical behavior of the fabric. Other attempts to make conductive textiles using silver nanoparticles and graphene and other carbon materials raise environmental concerns and come up short on performance requirements.

And the coating methods that are successfully able to apply enough material to a textile substrate to make it highly conductive also tend to make the yarns and fabrics too brittle to withstand normal wear and tear. High electrical conductivity and electrochemical performance are important, but so are conductive yarns that can be produced by a simple and scalable process with suitable mechanical properties for textile integration.

All must be taken into consideration for the successful development of the next-generation devices that can be worn like everyday garments. Dion has been a pioneer in the field of wearable technology, by drawing on her background on fashion and industrial design to produce new processes for creating fabrics with new technological capabilities. Her work has been recognized by the Department of Defense, which included Drexel, and Dion, in its Advanced Functional Fabrics of America effort to make the country a leader in the field.

She teamed with Gogotsi, who is a leading researcher in the area of two-dimensional conductive materials, to approach the challenge of making a conductive yarn that would hold up to knitting, wearing and washing.

Gogotsi's group was part of the Drexel team that discovered highly conductive two-dimensional materials, called MXenes, in and have been exploring their exceptional properties and applications for them ever since. His group has shown that it can synthesize MXenes that mix with water to create inks and spray coatings without any additives or surfactants -- a revelation that made them a natural candidate for making conductive yarn that could be used in functional fabrics.

It is approaching the conductivity of silver nanowire-coated yarns, but the use of silver in the textile industry is severely limited due to its dissolution and harmful effect on the environment. Moreover, MXenes could be used to add electrical energy storage capability, sensing, electromagnetic interference shielding and many other useful properties to textiles.

In its basic form, titanium carbide MXene looks like a black powder. But it is actually composed of flakes that are just a few atoms thick, which can be produced at various sizes. Larger flakes mean more surface area and greater conductivity, so the team found that it was possible to boost the performance of the yarn by infiltrating the individual fibers with smaller flakes and then coating the yarn itself with a layer of larger-flake MXene.

The team created the conductive yarns from three common, cellulose-based yarns: cotton, bamboo and linen. They applied the MXene material via dip-coating, which is a standard dyeing method, before testing them by knitting full fabrics on an industrial knitting machine -- the kind used to make most of the sweaters and scarves you'll see this fall.

Each type of yarn was knit into three different fabric swatches using three different stitch patterns -- single jersey, half gauge and interlock -- to ensure that they are durable enough to hold up in any textile from a tightly knit sweater to a loose-knit scarf.

To put the new threads to the test in a technological application, the team knitted some touch-sensitive textiles -- the sort that are being explored by Levi's and Yves Saint Laurent as part of Google's Project Jacquard. Not only did the MXene-based conductive yarns hold up against the wear and tear of the industrial knitting machines, but the fabrics produced survived a battery of tests to prove its durability.

Tugging, twisting, bending and -- most importantly -- washing, did not diminish the touch-sensing abilities of the yarn, the team reported -- even after dozens of trips through the spin cycle. But the researchers suggest that the ultimate advantage of using MXene-coated conductive yarns to produce these special textiles is that all of the functionality can be seamlessly integrated into the textiles.

So instead of having to add an external battery to power the wearable device, or wirelessly connect it to your smartphone, these energy storage devices and antennas would be made of fabric as well -- an integration that, though literally seamed, is a much smoother way to incorporate the technology.

Using conductive yarns also means that a wider variety of technological customization and innovations are possible via the knitting process. For example, "the performance of the knitted pressure sensor can be further improved in the future by changing the yarn type, stitch pattern, active material loading and the dielectric layer to result in higher capacitance changes," according to the authors. Dion's team at the Center for Functional Fabrics is already putting this development to the test in a number of projects, including a collaboration with textile manufacturer Apex Mills -- one of the leading producers of material for car seats and interiors.

And Gogotsi suggests the next step for this work will be tuning the coating process to add just the right amount of conductive MXene material to the yarn for specific uses. Materials provided by Drexel University. Note: Content may be edited for style and length.

Since warp knitting requires that the number of separate strands of yarn "ends" equals the number of stitches in a row, warp knitting is almost always done by machine. In warp knitted fabric the loops interlock vertically along the length of the fabric. Warp knits are slightly stretchy and do not ladder. Warp-knitted fabric is made by machine. It is used for swimwear, underwear and geotextiles. Because of the multiple-needle configuration of warp-knitting machines, the warp knit fabrics produced can be very complex and intricate in structure; and they don't fall neatly into groups or categories.

A knitting machine is a device used to create knitted fabrics in a semi or fully automated fashion. There are numerous types of knitting machines, ranging from simple spool or board templates with no moving parts to highly complex mechanisms controlled by electronics. All, however, produce various types of knitted fabrics, usually either flat or tubular, and of varying degrees of complexity. Pattern stitches can be selected by hand manipulation of the needles , or with push-buttons and dials, mechanical punch cards , or electronic pattern reading devices and computers. Early flat bed stocking frames had low carbon steel bearded needles where the tips were reflexed and could be depressed onto a hollow closing the loop.

Contemporary multifunctional textiles are based on hi-tech functionalization. Knitted structures can be relatively rapidly designed and produced in a variety of textures due to their composition of many interlacing loop elements and their combinations. Foldable weft-knitted structures exist in a wide range of forms from simple rolls, ribs, and pleats to more complex three-dimensional structures. They exhibit new kind of geometry and deformation mechanisms. Some of them exhibit auxetic potential.
