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.
Tubaloon■ pneumatic membrane
sculpture which was created for the Kongsberg jazz festival in Norway.
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.
