TECHNICAL TEXTILES

Technical textile materials used in Buildtech

Buildtech ■Tecnical textiles used in construction of

buildings are called “buildtech”

Application Areas

■ Civil engineering■ Industrial buildings■ Interior constructions■ Roofing■ Soundproofing applications■ Architecture■ Sun protection

Main productions

■ Hoardings■ Scaffolding Nets■ Awning and canopies■ Tarpaulins■ Architectural membranes■ Roofing materials

Properties ■ Light-weight ■ Resilience■ Flexibility■ Strength

■ Flame resistant■ Waterproof■ Resistant to UV light■ Non allergenic■ ....

Fibers ■ High-tenacity polyester (tensile properties,

strenght and cost)■ Glass fiber■ Nylon

■ Polyethylene■ Polypropylene■ HDPE(high density polyetylen)

■ Composites

Technologies

■ Plain constructions are used at woven fabrics ■ Warp knit fabrics ■ Nonwovens■ Coated fabrics for waterproofing ■ Laminated fabrics■ Innovative techniques

Textile architecture

■ Today, the textiles used in stadiums, sport complexes and fairs etc. They generally are membranes they are resistant to light and water and at the same time they are breathable.

■ When the textile elements are no longer required they can be folded up and stored compactly in a cupboard. In addition the fabrics are machine washable.

Planex firm building

■ During manufacturing both the warp and the weft yarn is pre-stressed and then coated. This guarantees a high level of surface stability and is a precondition for ensuring adequate wind resistance, which can only be guaranteed if the sails neither expand nor contract in response to changes in temperature.

Textiles for art■ In concerts, theaters or

artistic activities■ To transferring acoustic to the

audience

■ Nonwoven fabrics formed by needling technique

■ Biologically degradable fibers

DuPont membrane

Building Reinforcements■ In building construction, textiles

provide an efficient reinforcement strategy.

■ This is especially common in older masonry structures that are vulnerable to natural hazards.

■ with aesthetic and strength concerns, there are starting to produce spacer fabrics for heat and sound insulations.

■ To reinforce to concrete, also there are some sandwich structures which spacer fabrics and concrete are combined together.

To conclude

■ The future development of the buildtech markets and products will largely be centered upon new materials, new processes and new applications operating on a global basis for the development of economies of scale in production and product development.

■ Japan■ Germany■ the US ■ the UK ■ France■ Turkey ■ China and■ India

are the key producers of technical textiles.
