Thermoplastic refers to the quality of a fiber whose
molecular structure breaks down and becomes fluid at a certain
temperature, making it possible to reshape the fabric by pleating, moulding or crushing. The fabric is ‘fixed’ on cooling and cannot be altered unless heated to a temperature greater than the one at which it was reshaped.
MATERIALS:
Organza
Marbles, Stones
Rubber Bands
Pot of boiling water
Aluminium Foil
METHOD:
1. Create shapes on the fabric with the objects and secure them with rubber bands. Folding the fabric to create creases can also be done
2. Wrap the whole fabric in aluminium foil and place it into a pot of boiling water
3. Leave it to steam for about an hour
4. Remove the fabric from the hot water and allow it to dry
5. Remove the objects wrapped in the fabric
VACUUM FORMING
Vacuum forming, is a simplified version of thermoforming, whereby a sheet of plastic is heated to a forming temperature, stretched onto or into a single-surface mould, and held against the mould by applying vacuum between the mould surface and the sheet.
MATERIALS
Plastic Sheet
Vacuum Forming Machine
Objects to mould
METHOD:
1. Place the object to be moulded onto the platform and lower it down
2. Place the plastic sheet on the upper platform, on top of the object
3. Pull the heater over and allow it to heat up
4. After plastic sheet is heated up, push back the heater and on the vacuum pulling down the gear to raise the object
5. Plastic sheet will wrap around the object
6. Switch off the machine and remove object from plastic form
