ABSTRACT:
A fabric consisting of or incorporating a yarn, itself resistant to dyeing, and treated to color the yarn prior to forming the fabric by means of a continuous pigment pad-dyeing or coating process. The yarn is impregnated with a mixture of pigment and a binder and is drawn continuously through a roller nip to remove excess mixture. The yarn is next dried and thereafter wound. By using a continuous pad-dyeing process to treat the yarn prior to forming the fabric, the possibility is realized of increasing the color/color pattern choice for fire-resistant materials which are extremely difficult to dye and widening the choice of coloring process for the more generally used materials with practical and/or economic advantage for specials and/or smaller batches.
