Title: Process for the treatment of acrylonitrile polymer filaments and products resultingtherefrom
IPC: D01F6/18
Filed: 1961-04-05
Abstract: The surface only of acrylonitrile polymer filamentary material is impregnated with a mixture of zinc oxide and a volatile carrier, and the volatile carrier removed by drying so as to leave the material impregnated with a small proportion of zinc oxide. Acrylonitrile polymers, copolymers and terpolymers and blends of acrylonitrile polymers with other polymeric materials may be used, provided the proportion of acrylonitrile is at least 70%, preferably at least 80%. A long list of suitable other polymeric materials is given.  The zinc oxide content of the dry filaments is preferably 0.01-0.04%, especially 0.025-0.20%, and this is attained by the use of zinc oxide-carrier mixtures containing 0.02-0.8% zinc oxide.  Filaments may be immersed in a mixture of zinc oxide and volatile carrier, the latter being removed by heat. Preferably water is the volatile carrier.  In a preferred method, wet-spun filaments are treated in the "never-dried" condition by immersion in a bath of a mixture of zinc oxide and volatile carrier, desirably in a continuous process. Alternatively, zinc oxide may be incorporated (0.02-0.8%) in a filament finishing bath, expecially an aqueous emulsion containing 20-50% by weight non-ionic surface active ester, 15-35% by weight non-ionic surface active polyether and 5-25% by weight of a substituted carbamyl derivative.  Such finishing compositions are described in U.S.A. Specification 2,735,790.  Alternatively, never-dried wet-spun filaments may be continuously passed through an aqueous bath containing 0.02-0.8% zinc oxide, then through a finishing bath, consisting of a mixture of zinc oxide (0.1-0.8%) and an aqueous emulsion of a textile finish.  In another method, staple fibres are sprayed with a zinc oxide carrier mixture and then with a liquid finishing composition containing zinc oxide.  After impregnation of the filaments or fibres, excess liquid can be removed by squeezing and the impregnated material is then dried e.g. at 185-245 DEG C.  Filamentary materials so treated are non-corrosive to metals used in textile processing apparatus and exhibit enhanced dyeability to basic and disperse dyes.

Filed: 1938-04-27
Abstract: 508,250. Regulating reciprocating pumps; hydraulic presses. AMERICAN ENGINEERING CO. April 27, 1938, No. 12616. Convention date, March 15. 102 (i)] [Also in Group XXIX] A press 34 is supplied with liquid by a variable stroke pump 2 which delivers to a pipe 12 from which a pipe 73 leads to a piston 71 loaded by a spring 53 and is connected to the stroke varying mechanism. A valve 15 connects the upper or lower sides of the piston 33 to pump delivery or exhaust and plates 110, 111 on an arm 109 on the piston rod co-operate with contacts 112, 113 and 117, 118 to control solenoids 101, 106 which actuate a valve 95. Assuming the valve 15 is set, the pump supplies liquid to the underside of the piston 33 and the spring loaded piston 71 adjusts the pump so that a predetermined pressure is not exceeded. The valve 95 is set so that pressure liquid flows through pipes 91, 89, non-return valve 132, pipe 86 and loads piston 80 and moves it until it engages abutment 82 thereby increasing the loading of the spring 53 and thus the maximum pump pressure. When the contacts 117, 118 are engaged the valve 95 is moved to connect pipe 89 to exhaust whereby liquid acting on piston 80 is allowed to escape through the adjustable throttle passage 143 and the pressure on the spring 53 is gradually released. Specification 419,814 is referred to.
