Title: Improvements in or relating to crepe threads and fabrics
Filed: 1936-12-09
Abstract: 488,652. CrÛpe threads and fabrics ; embossing. DICKIE, W. A., and FINLAYSON, D. Dec. 9, 1936, No. 33833. [Class 120 (iii)] [Also in Group XVI] Fabrics containing highly twisted cellulose acetate threads which have been produced by a process in which at least the last part of the high twist is inserted while the threads are under the influence of steam or hot water, are embossed so as to bring about displacement of the threads prior to subjecting the fabrics to the action of a crÛpeing liquid. The highly twisted threads may be obtained, for example, according to the processes described in Specifications 437,019, 438,589, 438,590, and 438,591. Twisting may take place on a device in which the thread is drawn off over the end of a rotating package, or a ring twister may be used. The floating ring device described in Specification 304,806, [Class 120 (iii)], may be used to restrict ballooning of the thread and the tendency of the twist to run back to the package. The total twist applied is in general less than is necessary to give a satisfactory crepe effect without the embossing treatment, for example, a twist of 40-65 turns per inch is sufficient when embossing is employed, against 70-80 without the embossing step. The surfaces of the embossing rollers may have the appearance of a crÛpe fabric, or they may consist of small geometrical figures or close patterns of continuous lines. The fabric may be softened prior to the embossing operation, with solvents or softeners for cellulose acetate, a number of which are specified. Specifications 348,589, 378,054, 424,683, 424,752, 424,830, 424,879, and 446,738, [Group XVI], also are referred to.

The outer end of each spindle 7 of wing idler rollers 8 is located in a slot in an upwardly extending leg 10 of a bracket 11. The second leg 13 of the bracket bridges upstanding arms 14, 15 of a U-shaped clip 16 secured by a bolt 17 to a stringer tube 3.
