#########aint-Gobain Vetrotex yarns can be braided to produce tubular structures for various applications:

- because of the mechanical, thermal and electrical insulation
characteristics of glass products as well as the flexibility of the braid structure, protection of wiring under the hood of cars
- electrical insulation of wiring for domestic appliances, aeronautics,…
- sleeving, braid, rope used for thermal insulation as non asbestos heat resistant sealing gasket, expansion gasket, flame barrier...

A circular braiding machine is composed of two rotating sets of bobbins on which glass filament yarns have been wound. One set runs clockwise, the other one counter clockwise around the center
of the machine along a defined path. The bobbins of the two sets pass alternatively outside and inside according the path that allows the formation of the tubular braid structure. Its width is given by the take up speed of the braiding machine. In some application, the tubular sleeve can be braided on a core because the braiding structure can easily conform on any complex shape, the resulting product is called rope.

As the rubbing forces are high during braiding, plied yarns are often used to avoid break and fuzz accumulation.

Additionally, braids can be coated, impregnated, partially or fully heat cleaned to impart the characteristics requested by the end uses.
The end product is often called sleeving.

The Saint-Gobain Vetrotex single yarns can be used
for the production of braided structures.
The recommended size or linear density of the product depend
on the final end use.
