Spinning Polymers in Fibers and Material
Rolled Polyethylene Fill Units
Below are the different types of spinning used to make fibers, materials, and
polyethylene. Keep in mind, fiber manufacturers can use different spinning processes for the same fiber. For
example, modacrylic can be made using either dry spinning or wet spinning. Here’s a brief explanation of the
The polymer is dissolved in its solvent, evaporating the solvent into a stream of air or gas. This process is
used to create acetate, modacrylic, and spandex. All three materials are used in creating MCR Safety PPE in
the form of face shields, FR hi-vis vests, gloves, and aprons.
MCR Safety manufacturers the majority of our line of face shields at our U.S. plant
Polymer chains are bound together in a liquid crystal form before extrusion. This is the spinning process
used to make most HPPE and UHMWPE. Keep in mind, there are other variables that make up a final HPPE
solution produced by suppliers. This is why DSM Dyneema fiber is considered the coolest, most comfortable
UHMWPE on the market.
92763 uses UHMWPE, which is a gel spun polyethylene fiber.
A polymer substance is melted for extrusion through a spinneret, a plate with a number of small holes, before
being directly cooled. Nylon and polyester are created from this method. The majority of MCR Safety’s
general-purpose gloves use liners made from nylon or polyester, which becomes yarn via this process.
N9696 utilizes an 18-gauge nylon shell to bring you a 30% lighter glove compared to other
general-purpose nylon shells. Before it becomes a glove, the fiber in the shell has gone through
Fiber-forming substances are dissolved in a solvent, are submerged in a chemical bath, then emerge from a
solution into a solidified polymer fiber. Many of MCR Safety’s cut-resistant gloves that incorporate aramid
fibers use this process. Like UHWMPE, high-strength aramids use a gel spinning process, too. This is what
separates different fiber companies from one another: the process and additional minerals added.
MCR Safety’s Cut Pro Glove Made with DuPont™ Kevlar®
After the spinning process, the fibers are transformed into yarn by winding numerous continuous fibers
together into one single uniform piece of yarn. One fact around this point. MCR Safety doesn’t get involved
with the spinning of aramids, however, we’re the only DuPont™ Kevlar® licensee to take spun Kevlar® and spin
it into a final cut-resistant fiber.
Once into a workable fiber for glove production, HPPE and UHMWPE yarn is sent to our MCR Safety factory in
Mexico, to the NXG factory, and to
factory partners located all over the world. It’s this final yarn product that keeps workers’ hands
protected from the numerous extreme cut
hazards they face on the job every day.
