Introduction
All over the world technical textiles are
gaining more relevance. They can be applied in new innovative processes and
replace familiar materials and can be bonded with new materials for new
combinations. They are a good deal more flexible, stronger and resilient and
environmentally friendly-in their manufacture as well as in their processing
and application. It makes no difference if they are used in the construction,
the industrial or apparel sector. Technical textiles are hi-tech, innovative
products that can also be applied as an alternative. Their specific physical,
chemical, and technological characteristics are especially remarkable. A
decisive factor for their functionality is that these characteristics are also
guaranteed where they connect.
One of these most essential connection points in
technical textiles is at the seam. These provide a flexible and secure
connection for the manufacture of complex two or three dimensional products.
Embroidery technology is also utilised for technical textiles, for example in
the production of light-weight fibre composite structures. Whether sewn or
embroidered, sewing thread inserted into the textile material must maintain or
fulfil the function and the sometimes very demanding requirements of the entire
product.
PTFE sewing thread is from 100% pure Expanded
PTFE fiber, making it possibly the most chemical resistant thread on the market
today. In addition, it is completely unaffected by ultraviolet (UV) radiation
and will not degrade from continuous exposure to the sun! It will not rot,
support fungus or mildew. In addition, it is unaffected by fuel, cleaning
solvents, salt water, motor oil etc making your sewn seams as long lasting as
your fabrics / filter media.
GORE TENARA® sewing thread is made from 100% expanded PTFE
which stands for polytetrafluoroethlyene, and it is the chemical name for
Teflon®. The one significant difference between conventional Teflon threads and
GORE TENARA® sewing threads is that GORE TENARA sewing thread is manufactured from
100% expanded PTFE. Expanded PTFE is two to three times stronger than
conventional PTFE.
