Fiberglass yarn is produced by twisting or texturising continuous E-glass filaments into a fine, workable strand. It is the primary input for fiberglass weaving, braiding, and specialty technical textile manufacturing.
Fiberglass yarn begins as a bundle of parallel continuous filaments drawn from a bushing. These are then twisted — typically 20–200 turns per metre — to bind the filaments together and give the strand handling strength and abrasion resistance.
Textured or bulked yarns are produced by air-jet or mechanical texturising to increase surface area and loft, improving insulation performance and resin wet-out in some applications. The tex count (mass per 1000 m) defines the linear density, ranging from very fine 5 tex yarn for electrical applications to coarser 1200 tex yarn for industrial weaving.
All yarn is wound onto precisely built packages for consistent unwinding on high-speed looms, braiders, and winders. Package geometry and winding tension are controlled to prevent band-slippage and unwinding tangles.
Consistent filament diameter and twist per metre are critical to weave quality. Our yarn is produced under controlled conditions and tested for linear density, tensile strength, and twist before dispatch.
We supply on a range of package formats — cheese, cone, and tube — to match your equipment requirements.
All fiberglass yarn supplied by NaikGroup9 carries ISO 9001:2015, RoHS, REACH, and TÜV certification. Certificates of conformity are available on request and accompany all commercial shipments.
