Industrial Multifilament Yarns and Importance of Twist

Twist can impact the dynamics of your final product in many ways – strength, elongation, diameter, torque, lustre, softness etc. Unlike staple spun yarns, multifilament yarns lose strength as the twist is increased, therefore it is important to know the physical requirements required in the end product. Elongation increases with increasing twist, as does diameter, torque and lustre. Yarns become stiffer with twist therefore softness decreases.

Common Industrial Kevlar® and Aramid Yarn Applications

Dupont™ Kevlar®and other aramid yarns and threads are used in many industries including:

  • high temperature fluid hose manufacturing as reinforcement
  • electrical wire and cable for binding, ripcords, strength members and shielding (braided)
  • composite materials- aramid fabric is used for strength and reinforcement
  • ballistics, to sew proctective garmets, body armour and bullet proof vests
  • rope manufacturing for added strength
  • synthetic web-slings for sewing and round sling filler yarn
  • mattress manufacturing for sewing tape edge seams

Most of the products made with Kevlar® and other aramid yarns require high strength and/or fire retardant characteristics. The unique nature and production processes to make aramid fibers are some reasons aramids are much more expensive than other commodity fibers like cotton, polyester and nylon. Common characteristics among Kevlar® and other Aramid fibers include:

Top Processing Cure for Excessive Twist and Torque in Twisted Yarn: Conditioned Heat Setting

Lead Blog Post Image

As discussed earlier, there is nothing worse than trying to handle a torque/tension filled lively, kinky yarn or thread.  Each step of a manufacturing process such as twisting, spinning etc. causes tension in fiber, filament, yarn and thread.  Yarns tend to snarl/kink up in order to relax and rid themselves of tension.  Uncontrolled tension and subsequent snarling & kinking are likely to create manufacturing issues for our customers, and we do not want that!

High Speed Spiral Winding-Measure Yarn Cone Density and Increase Line Speeds

Lead Blog Post Image

One of our partners, a small-gauge hose manufacturing plant that runs around the clock, wanted to produce more product in less time. But their solution, to run machines 22% faster, caused our yarn cones to break and blow out. I visited the plant, where I used quantitative measures to determine what parameters may be optimum for even higher angular speeds and therefore greater out-puts.

Can You Identify Industrial Yarns & Fiber Threads?

Identifying Industrial Yarns & Fiber Threads

Have you ever needed more of a specific material, but weren’t sure what it was made of? There is a very simple test that anyone can perform to identify which fibers are in a material in mere seconds. All it takes is a sample of yarn…and a little fire.
