Title: Improvements in or relating to the treatment of textile materials
IPC: D06M15/09
Filed: 1939-02-10
Abstract: 524,959. Coated fabrics. CRAIK, J., HOUGHTON, A. A., and IMPERIAL CHEMICAL INDUSTRIES, Ltd. Feb. 10, 1939, No. 4504. [Class 140] [Also in Group IV] The surface hairs of jute textile materials are laid and fixed by applying to the surface of the material an aqueous alkaline solution of a cellulose ether which is insoluble in water but soluble or capable of being rendered soluble in dilute aqueous alkali, then laying the hairs by a mechanical smoothing device, and subjecting the material to a wet-coagulation process While the surface hairs are still laid. The process may be applied to the treatment of rough fabrics such as are used in the production of bales, sacks, bags and the like. The process eliminates the usual shaving or singeing process. Dilute acids, or solutions of ammonium salts may be used as coagulants. The cellulose ether solution may be applied to one or both sides of the fabric by padding or other methods and the hairs may be laid by means of an ironing bar, slot, die, doctor, or rolls. Application of the solution and smoothing may be conducted on the same machine, e.g.. a three-roll mangle. In an example, jute cloth is impregnated with a 3 per cent. solution of methyl cellulose in caustic soda solution and then given a similar treatment with a 7 per cent. solution of methyl cellulose. It is then drawn through a slit or between spring-pressed doctors, and immersed in dilute acid, washed and dried. In another example, jute fabric is impregnated with a solution of glycol cellulose obtained by mixing the cellulose ether with dilute caustic soda in presence of a dispersing agent or by cooling the mixture to below -3‹C. and then allowing the temperature to rise. The fabric passes through nip rolls into and out of the bath, and then between two doctors. It is then passed through dilute acid, washed, and dried under tension. Pigments. pesticides, rot-proofing agents, and the like, e.g., titanium dioxide, copper or arsenic compounds, may be added to the cellulose ether solution to increase the resistance of the fabric to light, moulds, insects, or other destructive agents. Specifications 410,152 and 410,153, [both in Group IV], are referred to.

Filed: 1924-02-23
Abstract: 231,986. Grieve, T. S. Feb. 23, 1924. Stop-motions operated by the needles. The invention is applicable to rotary-reciprocatory-circular machines and is described in connection with the superposedcylinder type with rotary camboxes. A bracket 2 attached to the rotary ribber arm 1 carries a spring-controlled vertically slidable rod 3 having at the upper end a radially projecting finger 5. A pin 6 working in a slot 7 prevents the rod 3 from turning. An axle pin 8 mounted in the bracket 2 carries an arm 9, which normally holds up the rod 3, and a spring-controlled lever 12 one arm of which engages the arm 9 while the other carries an adjustable detector pin 14. When the pin strikes an obstruction such as a displaced needle it will if the ribber arm 1 is continuously revolving allow the rod 3 to lower the finger 5 into the path of an arm 19, but if the arm 1 is moving in the opposite direction the pin 14 will yield so that the rebound of the lever 12 operates the stopmotion. The arm 19 is mounted on a spring pressed vertically slidable rod 20 near the lower end of which is a cross pin 25 normally resting in recesses in a bearing 22. When the rod 20 is turned the pin 25 is released and travels down inclines 26 and allows the lower end to strike a bell-crank 27. The lever 27 may, shift the belt from the fast to a loose pulley by acting on a lever 28, an axially movable toothed sleeve 30, a bell crank 33 and a spring controlled arm 36 connected to the belt fork.
