What are Technical Textiles?
- Textile materials which are used for technical issue not for
clothing or fashion.
- Textile material and products which are manufactured
primarily for their performance and functional properties
not aesthetic or decorative purpose

- Polymer laid nonwoven (US$ 66.6 million).

13. Cairo Textile Week,16-17 October, 2021.
- Mostly synthetic, regenerated or inorganic fibres are used, and
natural fibers for less demanding technical applications.
• Inorganic fibres; glass, carbon, ceramic, basalt and
steel…etc.
• synthetic fibers;
- Super high-modulus polymer fibers: aramids, HMWPE (super
High Molecular Weight Polyethylene).
- Thermally and chemically resistant fibers: PEEK (Polyether ether
ketone), PTFE (Polytetrafluoroethylene).
• Natural fibres; cotton, jute, bamboo, coconut, banana, palm
and sisal fibers.

What Are Laminated Fabrics and Materials?
- Coating and laminating are increasingly
important techniques, and the use of these
techniques is growing rapidly as the applications
for technical textiles become more diverse
Laminated fabrics are composed of two or more layers,
at least one of which is a textile fabric and at least one of
which is a substantially continuous polymeric layer. The
layers are bonded by means of an added adhesive.
