Fiberglass Glossary
Includes the most important technical terms regarding glass fiber products, their production process and their applications
T
Tail
Small piece of yarn wound and fixed around the base of the bobbin before the start of the twisting process. It allows the splicing of two packages in order to make possible the continuous supply of textile processing.
Tape
A narrow fabric.
Tissue
A non-woven fabric composed of chopped filaments used as a reinforcement material for flooring and roofing (also known as roofing mat).
Tex
A direct yarn numbering system that gives the linear density, as being the mass in grams per 1,000 meters of yarn length.
Texturized product
In the texturizing process, the glass yarns or strands are overfed in a nozzle in which an air stream creates a turbulence that causes a disorganization of the structure and the formation of loops. The texturizing effect can be fixed by chemical means.
Tow
A large number of filaments gathered substantially without twist (according to ISO/DIS 13922).
Tubing (in textiles)
A tubular structure with a collapsed width greater than 100 mm (according to ISO/DIS 13922). Also called sleeving.
Turbofil®
The Vetrotex registered trade name for voluminized and texturized products.
Twill weave
A weave characterized by diagonal lines produced by a series of floats staggered in the warp direction, which are normally formed by the filling (a filling-faced twill) (according to ASTM D 4850).
Twisting
Process that imparts to the strand from the cake a slight twist in order to improve the abrasion resistance and the strand integrity of yarns.
Type of weave
Method of interlacing warp and weft to give a regular, repeating pattern of weaving, for example, plain, satin, twill, etc. (according to ISO/DIS 13922).
U
Unidirectional fabric
A flat structure with a great number of yarns in one direction.
V
Voluminized product
In the voluminized process, the glass yarns or strands are fed into a nozzle in which an air stream creates a turbulence, imparting bulk.
