Check out this brilliant article by Orna Mulcahy in Saturday's Irish Times.
She gives a couple of very interesting insights into wool:
1. The Campaign for Wool (founded by Prince Charles) buried 2 garments in the ground. One was made of polyester, the other wool. Six months later they were both uncovered, the results - “the wool jersey had all but disappeared with a few fat worms digesting the final strands” and the polyester was completely unchanged to the point “You could have put it through the washing machine and worn it again”. Need I point out the obvious?
2. Further, every year millions of barrels of oil are used to manufacture polyester fabric, also polyester is difficult to recycle. Whereas wool is from a renewable resource and we know it decomposes naturally. Not to mention it is breathable, gives sun protection, is naturally odour-resistant, and beautiful to wear.
Thumbs up for Wool, all the way! Especially Merino Wool!
