<p>The fabric is made using a weft with a very fine warp thread of 45-70 denier and with a minimum number of warp threads, so that the weft predominates to the maximum extent. The weft threads are much thicker (20 Nm or more) and are made of chopped synthetic fibres (acrylic, polyester, polyamide, etc.) which do not contract at a given temp. and are mixed with similar fibres which have been given heat-retracting properties.</p> |
