Engineered Yarn Processes

Since 1920 Concordia Fibers has specialized in the design and development of engineered yarns and fibers for producing a broad range of technical fabrics. We usually start with continuous filament synthetic polymer yarns which we process in a variety of ways meet our customers’ (weavers, knitters, braiders) requirements.  Our fibers can be found in filtration media, power transmission belts, air bags, parachute cords, and a variety of other unique applications.

 

There is almost no synthetic polymer that Concordia has not processed.  The most common are nylon and polyester, but we work with all the aramid fibers, polyethylene, polypropylene, carbon, and stainless steel, to name a few.

 

 

Processes:

  • Twisting

    Adding twist to continuous filament yarns helps lock the filaments together making the yarn easier to weave.  Different levels of twist can have dramatic effects on the final fabric.  As more twist is added to a yarn the bundle of fibers which make up the yarn become rounder.  Concordia can insert anywhere from 0.5 turns per inch to 50 turns per inch depending on the raw fibers we start with.

  • Winding

    Depending on the fabric formation processes our customers’ use, our yarns need to be on different sized tubes, cones, or other packaging shapes.  Winding is simply the process of transferring a yarn from one type of package to another.

  • Texturing

    Sometimes instead of twisting customers want to bulk up or make a yarn fluffier.  This is done by adding crimp to the individual filaments within a yarn.  There are several different techniques for adding crimp to yarn.

  • Plying

    Plying is when several different ends of yarn are twisted together.  The ends could all be of the same type of yarn or different kinds of yarn.  Concordia makes a conductive yarn which is a combination of a polyester yarn and a filament of stainless steel.

  • Serving

    A process of wrapping or covering a yarn with a different surface yarn compacting the original yarn bundle.

  • Heat Setting / Conditioning

    Adding high levels of twist to a yarn can make it “lively” as it wants to untwist when not under tension.  Putting the yarn in an autoclave and adding heat and moisture can permanently “set” the yarn bundle so it will not untwist.
