1.1. lntroductwn A high proportion of woven carpets in UK, and a smaller proportion of tufted cut - pile carpets, have a pile composed of 80 % wool and 20 % nylon. The presence of such carpets in other countries, resulting from UK exports, has led to manufacturers in these countries to consider the production of 80 120 wool / nylon carpets. This report attempts to review the technical factors which must be considered when deciding whether to make a carpet in 100 % wool or 80 120 wool / nylon. 1.2. Manufacturing Yams from 80 / 20 blends are stronger than 100 % wool yams, but blending also.introduces disadvantages, and no important changes in processing costs may be expected. Blending Blending of 80 120 blends must be carried out particularly carefully to avoid faults in the carpet due to local high concentration of nylon. Blend costs will be lower for the wool I synthetic blend because of the lower price of some nylons. This can lower the total cost of making the carpet up to 9 % , depending on whether premium nylon or sub - standard nylon is used, and whether the quality of wool is reduced, relying on the nylon to provide yam strength. Maximum saving can only be achieved by lowering the quality of the carpet, e.g. by using waste which may contain undrawn nylon. Care should be taken in using percentage mark-up calculations, since profits per square meter may be reduced
