Filed: 1938-06-13
Abstract: 515,847. Dyeing textiles. COURTAULDS, Ltd., WHITTAKER, C. M., WILCOCK, C. C., and TATTERSFIELD. C. P. June 13, 1938, Nos. 17562/38 and 7675/39. [Classes 2 (iii) and 15 (ii)] The affinity for dyestuffs of textile materials, e.g. silk or casein fibres, cotton, linen, viscose or cuprammonium regenerated cellulose or deesterified cellulose esters, is increased and the fastness of the dye is improved by treating the materials, before or after dyeing, with a solution obtained by dissolving in acid the product of interaction of cyanamide with formaldehyde. Such product may be obtained by passing formaldehyde vapour over solid cyanamide or over or through molten cyanamide or by reaction in aqueous solution at a pH value of 6 or more e.g. at 70C., and separation of the, resulting precipitate. If the treatment is before dyeing, more complete exhaustion of the bath. is obtained in dyeing with dyestuffs of the " Soledon " (Registered Trade Mark), Indigosol, azoic, sulphur, basic and direct cotton dyes and an affinity for acid dyes is imparted to cellulosic materials. Treatment before or after dyeing improves the fastness to cross-dyeing, cold water steeping, perspiration, desizing compounds and washing. Addition of a small proportion of copper acetate to the treatment solution improves the fastness of the dyeings to light. In examples, (1) aqueous formaldehyde is added to a solution of cyanamide (obtained by neutralizing a solution of crude calcium cyanamide with strong sulphuric acid and filtering off the calcium sulphate), the solution is made slightly alkaline with caustic soda precipitated condensation product is filtered off, washed, dried and dissolved in dilute acetic acid ,and a fabric of regenerated cellulose staple fibre is treated with the solution for 15 minutes at 60C. and dyed in a bath at 60C. containing Indigosol blue I.B.C. and sodium chloride ; (2) a similar fabric dyed with Solar rubinole B is treated for 20 minutes with an aqueous acetic acid solution at 40C. of the condensation product in (1), washed and dried ; (3) aqueous formaldehyde.is added to a solution of cyanamide (obtained by adding hydrochloric acid to a solution obtained by filtering a slurry of calcium cyanamide) and the condensation product, separated as in (1) is dissolved in dilute acetic acid and a fabric of regenerated cellulose staple fibre, dyed with -Chlorazol fast black B.K.S. is treated with the solution for 20 minutes at 40C. ; (4) a similar fabric, dyed with Viscose blue grey N.B., is treated for 20 minutes at room temperature with an aqueous acetic acid solution of the condensation product in (1) containing 2 per cent. of copper acetate.

Abstract: 329,864. Hoe & Co., Ltd., R., (Hoe & Co., Inc., R.). June 8, 1929, Feeding webs.-In a web roll controlling device comprising a floating roller 37 controlling a brake 16 acting on the spindle 13 of the web roll 14, a retarding device is arranged to permit free movement of the floating roller when the web tightens, and to restrict such movement when the web slackens. The, web 31 passes around a roller 32 mounted in independently adjustable bearings and continues around the floating roller 37 which is rotatably supported in arms 38 secured to a shaft 39 journaled in bearings in the frame 11. An arm 42 secured to the shaft 39 is connected to the brake through a rod 46 and a tightening of the web causes the floating roller 37 to move up, thus rotating the shaft 39, depressing the arm 42, and actuating the brake. The effective weight of the floating roller may be varied by means of a weight 44 adapted to slide on a rod 43. The arm 38 carrying the floating roller is connected to a dash-pot which is pivoted on the frame 11. The piston rod 52 of the dash-pot slides in a swivel connection 53 rotatably mounted on the arm 38. A spring 55 extends between the swivel connection and a collar 54 which, with a sleeve 54<1>, is secured to the piston rod. A collar 56 screwed on the end of the piston rod 52 serves to adjust the gap between the end of the sleeve 54<1> and the swivel connection 53 and to vary the free downward movement of the floating roller. The dashpot may contain oil or any suitable fluid and a check valve is described which allows the fluid to pass readily from the top to the bottom of the piston but restricts its passage in the reverse direction. This dash-pot arrangement allows the floating roller 37 to rise unrestricted, and also to descend freely for a limited distance, but further downward motion is resisted. A handwheel 23 serves for varying the intensity of the braking pressure and a handwheel 28 positions the braking device axially. The floating roller may be arranged to operate in the opposite direction, and in this case an adjustable spring is used to vary the effective weight of the floating roller, and the adjustable roller 32 is omitted, its function being performed by the floating roller which is arranged so that one of its supporting arms is adjustable relative to the other.
