Abstract

1,171,170. Finishing fabrics and yarns; textile treating apparatus. UNITED MERCHANTS & MFGS. Inc. 29 Nov., 1966 [24 Jan., 1966], No. 53507/66. Headings D1F, D1L and D1S. Texturized and multi-tone dye effects are produced on a glass fibre fabric 21 or yarn by abrading surface areas 21a of the fabric or yarn to produce textured effects and/or enhance the dye receptive properties of these surface areas. The fabric 21 comprises glass fibre filaments and/or spun yarns. As shown in Fig. 1, fabric 21 from a supply roll 10 passes around guide rolls 15, past a yardage counter 16, through the nip formed between a rubber-covered pressure roll 12 and a sander roll 13 and is taken up on a roll 11 driven by a motor 19. The roll 12 is adjustable towards and away from the roll 13 by a micrometer-like handwheel 17 and is rotated by a motor 20. The roll 13 is simultaneously rotated and oscillated by a motor 18 which also coacts with pulleys to actuate a device 14 which removes lint or abraded fibres by suction. The fabric 21, Fig. 2, to be dyed, passes from a supply roll into a bath 24 of dyestuff in which it passes under two rollers 23, between squeeze rolls 25 and into a heated curing oven 27 through which it is guided in zig-zag fashion around rollers 28. The fabric 21 then passes through a further bath 30 containing a wash fastness agent and a binder for the dyestuff, between squeeze rolls 32, through the first part of a heated curing oven 34 in which it passes in zig-zag fashion, through an afterfinish bath 30a, between squeeze rolls 32a, through the second part of the oven 34 in zig-zag fashion and is wound on a roll 37. The fabric 21 may be comprised of surface floats disposed in a pattern, e.g. a diamond pattern, or design with the remaining portion having no pattern thereon in which case the roll 13 is covered substantially all over -its working surface with sand paper so that the patterned areas only are texturized. A roll 13 covered with only a limited length of sandpaper may texturize the patterns on only part of the fabric 21, Figs. 5 and 6 (both not shown). Alternatively, this effect is produced by masking off a portion of the length of a completely covered roll 13. Line patterns, both oblique and longitudinal, may be produced on a plain weave fabric by suitably covered rolls 13, Figs. 7 and 9 (both not shown). A pattern of squares and width-wise bars may be produced by the roll 13 shown in Fig. 15 and having sandpaper parts 58, 59. The textured areas of the fabric may be lighter or darker than the remainder according to whether abrading takes place after or before dyeing, respectively.
