Technical Textile

1. Architextiles
&
Buildtech

2. Introduction
• ArchiTextiles
– Textiles for architectural purpose
• Buildtech or Buildtex
– Textile used in buildings and Construction
• Technical and functional performance
• Indoor and outdoor for surface as well as hidden
applications
• Used in acoustic & thermal insulation, protection of
building against sun, wind, fire, water
• Textile usage - 1/30 of the weight of brick, steel or
concrete

3. Why Textiles
• Energy efficiency
– The textile production process
– Fabrication & installation of membrane systems
• Cost efficiency
– Economy & efficiency of materials used
• Recyclability
– PVC textiles are now fully recyclable
• Deconstruction
– Far simpler than traditional structures

4. Application
• Concrete reinforcement,
• Foundation systems,
• Interior constructions,
• Insulations,
• Proofing materials,
• Visual protection,
• Protection against the sun,
• Building safety,
• Textile membranes for roof construction,
• Hoardings and signages,
• Scaffolding nets,
• Awnings and canopies,
• Tarpaulins,
• Architectural membranes and roofing materials.

5. Fibers used
• High-tenacity polyester
– (tensile properties, strength and cost)
• Glass fiber
• Nylon
• Polyethylene
• Polypropylene
• HDPE
– (high density polyetylen)
• Composites

6. Properties
• Light-weight
• Resilience
• Noise prevention
• Flexibility
• Strength
• Flame resistant
• Waterproof
• Resistant to UV light
• Non allergenic

7. Fabric Construction Technologies
• Simple weaving
• Double weaving
• Warp knitting
• Non woven
• Coated fabrics for waterproofing
• Laminated fabrics
• Innovative techniques

8. Membrane & Solar Behavior
• Forms the enclosure of the structure
• Connections can be glued or heat welded

10. Fabric Membranes
• PVC coated polyester (polyvinylchloride)
– Less expensive
– 15 to 20 year life span
– Easy to erect
• Silicon coated glass
– Higher tensile strength
– Brittle, subject to damage from flexing
– 30+ year life span
• Teflon coated glass P.T.F.E (polytetrafluroethylene)
– Similar to silicon glass, less brittle

11. Architextiles
• Fabric is elastic and stretches
• Advantages
– Unique designs
– Lightweight and flexible
– Environmentally sensitive
– High strength weight ratio
• Disadvantages
– Little to no rigidity
– Loss of tension is dangerous for stability
– Thermal values limit use

12. Types Structures
• Saddle roof
• Mast supported
• Arch supported
• Point supported
• Combinations

13. Cont.
• Saddle roof
– Four or more point system
– Fabric is stretched between a set of alternating
high and low points
• Mast supported
– Tent - like structures containing one or more peaks
supported by poles

14. Cont.
• Arch supported
– Curved compression members
– Cross arches are used for lateral stability
• Point supported
– Aluminum frame
• Combinations
– Several support types

15. 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.
• These are used to prevent the harmful UV rays from sun light.

16. Tubaloon
• Pneumatic Membrane structure
• Stabilized by the pressure of compressed air
• A network of cables stiffens the fabric, and the
• assembly is supported by a rigid ring

17. Textiles for art
• For acoustic
• Teflon fiberglass composite materials are used for
noise reduction
• Absorbent textile materials : carpets, textile wall
coverings and curtains
– To improve audibility
– To preserve the natural quality of sound
– To prevent transmission of undesired sound

18. Building Reinforcements
• In building construction, textiles provide an
efficient reinforcement strategy.
• Materials are used in concrete reinforcements
in order to with stand earthquakes.
