Yarns & Braid Components

Yarns, Braider Packages & Uncoated Braid

Varflex Corporation was a pioneer in the manufacturing of electrical insulating sleeving in the United States and sleeving has been our only business since our founding in 1924. We continue to do our own twisting and plying, yarn winding and braiding in-house and the expertise we have developed and honed over those many years, reinforced by our reputation for quality, is now available to those customers who wish to supplement their own operations through the purchase of Twisted and Plied Yarns, Braider Packages and/or Uncoated Fiberglass Braid.


Twisted & Plied Yarns

Twisted and plied yarns from Varflex start with single-strand yarns composed of continuous, multi-filament fibers that are turned in the "Z" (reverse) twist direction.

Our ply frames ply two or more strands by twisting the strands in an opposite "S" (forward) twist direction into a balanced, multi-end yarn product having the desired diameter as well as increased tensile strength.

Twisted and plied yarns are furnished in various-sized "milk bottle" packages (plastic tube with base) or on a double-flanged plastic bobbin. Twisted and plied fiberglass is supplied with the starch-oil based sizing (binder) that was applied during the yarn manufacturing process to improve subsequent handling and fabrication operations.

  • Fiberglass. See Table 1
  • Other FIbers. See Table 2
  • High Performance Yarns. See Table 3

Note: Twisted and Plied Yarns are available on 8512, 8535, 8540 and 9228 bobbins.


Braider Packages

Braider packages from Varflex are produced in our Winding Department where twisted and plied yarns produced to your specifications are transferred to "braider packages" suitable for use on New England Butt-type and Wardwell braiding machines. During the winding process, we can combine different yarn constructions giving you the ability to braid a variety of sleeving sizes.

  • Plied Fiberglass Yarns. See Table 1
  • Other Yarns. See Table 2
  • High Performance Yarns. See Table 3

Braider packages are available on the following tube sizes:

  Tube SIze Wound Package O.D.
  5/8” I.D. x 4-1/4” Length Per Customer Specification
  5/8” I.D. x 5-1/4” Length Per Customer Specification
  Parallel winding is available on bobbins.

Uncoated Fiberglass Braid

Varflex has braiders with a wide range of carriers which enable us to supply uncoated fiberglass braid in a variety of types and sizes.

And, for those requirements not satisfied with a standard braid construction, Varflex stands ready to provide you with special braiding as well as heavy-, double-, and triple-wall construction, all to your specifications.

  • AWG Size #30 through 2" I.D. See Table 1

Note: Uncoated fiberglass braid is available on 20" and 24" diameter returnable reels having a 6" traverse.
