摘要

A fabric of thermoplastic yarns, which is capable of being lined with loop pile (terry pile), is superposed with a ply of thermoplastic fibres, and the combination is passed into a heated calender, without needling. The fibres of the ply become bonded to the fabric and to each other. The backing thus obtained is particularly suitable for manufacturing fine-gauge loop-pile (terry-pile) carpets. IMAGE
