Elders Primary Wool have introduced technology that will identify the source of wool in their carpets. New Zealand claims to grow the best strong wool in the world. Most of this wool is used in carpets. They want to be able to certify that their carpets contain NZ wool so have knitted a tracer fibre, invisible to the eye, into the wool fibre. This tracer can be doused with a signature marker and detected with a hand held scanner. The technology has been developed by AgRearch in New Zealand in conjunction with scientists from CSIRO.
If people, world wide, need certainty that what they buy is what retailers claim there may well be more of these tracer fibres in our food and fibres in the future.
