FIBERGLASS CONTINUOUS FILAMENT YARN FOR THE PAPER, FILM AND FOIL
INDUSTRY

I.

DESCRIPTION
Fiberglass yarn is a natural, lustrous, white, continuous filament yarn which is twisted on
various supply packages. The yarns are smooth, non-cellular and generally cylindrical in
form. The yarns are made of glass of high stability and durability and are with the
exception of sizing ingredients, inorganic, incombustible and will neither expand nor
contract with moisture changes. The glass composition meets the certification for “E”
glass as defined by ASTM’s D 578-00 Standards Specification for Glass Fiber Strands.
The individual glass fibers do not tend to absorb moisture and are extremely flexible.
The sizing may be burned off the yarn under certain conditions. Weathering tests have
indicated comparatively unlimited stability under repeated cycles of heat, cold, sunlight,
dampness and drying.

II.

USE
These yarns are used as reinforcements in the manufacture of laminates of paper, film,
foils or combination thereof.

Throughout history, the actual yardage or TEX of yarn products has often been shifted
from the actual yield provided in the product name. Therefore, the yarn name is only
used as a descriptor. The table in section V. must be utilized to obtain the actual bare
glass yield of a yarn product.
