About pleat holding and non wrinkle. I am also after the same type of kilt as Newfoundlander for daytime going out. I have my 16oz wool tank for best.

I have a pair of pants/trousers made of as stated on the label, 100% polyester. They are branded Farah. I have had them for about 5 years and they have been washed in a washing machine many many times.
They have never needed pressing and the creases are still as sharp as new.
The creases are not stitched or glued and I have looked with a powerful magnifier.

So how is this done and are there any kilts made with this stuff? and if not, why not?

Is polyester the same as polyviscose etc?

Chris.
