Fiberglass Yarns

Fiberglass yarns consist of a defined number of E-Glass filaments of a certain nominal diameter, brought together to form a yarn. The structure of the yarn is fixed and protected by a size and a slight twist, generally in Z-direction. 

Our E-Glass fiberglass yarns are wound on plastic bobbins and supplied in a “milk bottle” shape. Vetrotex glass yarns can be also supplied on beams. The glass composition meets the certification for E-Glass as defined by ASTM’s D578-00 Standard Specification for fiberglass filaments.

Product Range

  • T63

T63 is a starch/ silane /oil-based size system. 

Due to its special composition, all fiberglass yarns sized with T63 have a high tensile strength. 

The size abrasion is reduced to a minimum and the electric static build up is very low, even under demanding conditions. 

  • T8

Starch/ oil-based size system, being suitable for a large variety of textile processes

  • T30, T32, 5312 & T34 

Starch/ oil based size systems, especially designed for high speed air jet weaving machines and applications requiring good heat cleaning properties. 

  • TD22, TD37, TD44 

Starch-free plastic size systems, containing silane bonding agents guaranteeing an excellent compatibility with different Thermoset resin systems (epoxy, phenolic and unsatured polyester). 

  • TD55

The size system is especially designed to provide excellent compatibility with PVC plastisols. 

  • T18

This size system is especially designed for texturizing, providing a very good protection for a mechanically demanding process and offering a high tensile strength.

Fiberglass Advantages

  • LOW THERMAL CONDUCTIVITY
  • FIRE RESISTANT
  • ELECTRICAL INSULATION
  • COMPATIBILITY WITH ORGANICS MATRICES
  • 3X HIGHER SPECIFIC RESISTANCE THAN STEEL
  • DIMENSIONAL STABILITY

Related Applications

Related Technologies

  • Weaving

    The weaving machine, or loom, interlaces the warp and filling yarns according to a weave pattern to form a fabric structure.

  • Knitting

    Knitting is a process in which three different yarn sources are used to form a fabric. Beyond warp and weft yarns, a stitched yarn is used to tie the warp and weft yarns together.

  • Coating

    Various chemical substances can coat either glass filament yarns or fabrics. Major applications are PVC coated yarns, PTFE coated fabrics and specific properties of PTFE fabrics.

  • Finishing

    Fabrics or textile structures made of glass filament products can be impregnated with various chemicals to impart the characteristics required by the end application.

  • Warping & Beaming

    Beaming is an operation in which a defined number of parallel ends on single yarns from a creel are combined and wound with tension on a section beam or on a wrap beam.

  • Multiaxial

    The multiaxial machine is used to produce multi-layer structures for reinforcement applications. Major applications for multiaxial products include composites for the boat and shipping industries and rotor blades for power stations.

  • Braiding

    Vetrotex fiberglass yarns can be braided to produce tubular structures. The flexibility of the braid structure, as well as the mechanical, thermal and electrical characteristics of glass, make braided fiberglass  ideal for many products. 

  • Laid scrim

    The laid scrim machine is another textile process that allows the manufacture of products called scrims in which the warp and weft are also widely spaced and fixed by chemical means.

  • Texturizing & voluminizing

    In the texturizing process, the glass yarns or strands are overfed into a nozzle in which a pressurized air stream creates turbulence, that causes the formation of loops and imparts a moderate bulk.
