LUTRADUR & TYVEK
Both Lutradur & Tyvek react to heat and bubble and shrink – Lutradur will form holes quicker than Tyvek. Lutradur is a bonded fabric (it looks like vilene) which remains reasonably flexible after heating. If you use fabric paints to colour it the paint will sink all the way through Lutradur (in fact you could put another fabric underneath – for example your Bondaweb – and virtually colour the 2 pieces together). Tyvek is more like a paper product (with a softer fabric version also available) but in both case when it is heated it is much harder and rigid. When you paint it you must also paint both sides as the paint will remain on the surface.
WORKING WITH LUTRADUR
Lutradur can be heated with an iron or a heat gun. The heat gun will make it shrink and bubble to form holes. It can be stitched through (remember that synthetic threads may melt if you stitch prior to heating). It is available in various weights, the most popular being 30, 70 & 105 gsm (105 being the thicker). It can be coloured with dyes or painted with paints – fabric paint is good and the heat seals the colour in if you colour it before you heat it. Make sure you do not paint too thickly or it will not form holes when heated. If you are not worried about fixing the colour (eg for wall art where a final varnish will be used) you can heat the Lutradur first and colour afterwards.
Lutradur can be enhanced by adding various other items such as fabric, wools, beads, sequins etc. This can be achieved by either stitching or using Bondaweb. To use bondaweb paint the material and allow to dry totally. Remove the backing paper and lay onto the Lutradur. Add threads, material etc and place a Teflon sheet over them before ironing through the Teflon (a cotton setting). Allow to cool before removing the Teflon.
WORKING WITH TYVEK
Tyvek paper is used extensively in crafts & textiles and in jewellery for making beads. It is a synthetic fabric with appearance of paper which will shrink and bubble when heated to give amazing effects to your work. Also used for creating unusual background effects and toppers for cards.
- Cut your Tyvek with ordinary scissors (it is virtually impossible to tear by hand) and then colour it on both sides – do one side and allow it to dry before turning over to do the second side. You can colour the Tyvek with Fabric Paints, Felt Tip Pens etc. It is also possible to print onto the Tyvek with an Ink Jet Printer (not a laser printer or photocopier).
- If you are stitching into your Tyvek do it before you heat it (it gets harder when heated and whilst you can do enhancements by hand after heating it is too hard to machine successfully once heated). Be careful with your choice of threads as synthetic threads could melt when the heat is applied.
- Place the Tyvek between 2 Teflon sheets and iron lightly and the Tyvek will bubble and distort. Using a heat gun on the Tyvek (with the Tyvek on a Teflon Sheet) will create a more bubbled and three dimensional effect. (Teflon sheet is available in my shop). Allow to cool before removing from the Teflon.
- If you have coloured the piece with Fabric Paint the application of the heat will have also set the colour permanently.
