Abstract: Apparatus for continuously performing chemical processes and reactions which require heat administration from the outside and are conducive to the evolution of volatile by-products, such as the processes leading to the production of spinnable polyesters, comprising a reactor having substantially vertical metal walls, means for introducing the reactant and, if desired, a recycled reacted product at the reactor top, centrifuging means for hurling the material or materials introduced at the top of said walls so that it or they descend in the form of a liquid film therealong, and means for recycling a fraction of the product, which has been collected at the base of the reactor, towards the top thereof.

Abstract: A PROCESS FOR CONTINUOUS PRODUCTION OF A SPINNABLE POLYESTER INCLUDING A PLURALITY OF STEPS OF PRECONDENSATION OAND OF PROGRESSIVE CONDENSATION ACCOMPANIED BY REMOVAL OF GASEOUS CO-PRODUCTS. THE INDIVIDUAL STEPS ARE CARRIED ON APPLYING THIN-LAYER TECHNIQUE WITHIN SEPARATE ENVIRONMENTS AT DIFFERING TEMPERATURE AND PRESSURE CONDITIONS AND WHEREIN THE WALLS DEFINING SAID ENVIRONMENTS ARE SO HEATED TO MAINTAIN THE TEMPERATURE GRADIENT AT THE INTERFACE OF WALL AND LIQUID THIN LAYER WITHIN A SMALL VALUE PREFERABLY NOT GREATER THAN 6*C., AND THE SAID LIQUID THINLAYER IN EACH ENVIRONMENT PREVAILINGLY CONSISTS OF PARTIALLY REACTED PRODUCT RECYCLED IN SAME ENVIRONMENT. AN EQUIPMENT COMRPISING A PLURALITY OF REACTION ENVIRONMENTS, RECYCLING MEANS AND SURFACE HEAT-EXCHANGING MEANS FOR CARRYING OUT THE PROCESS.

Abstract: A METHOD AND A DEVICE ARE DISCLOSED FOR IMPROVING THE COHESION BETWEEN INDIVIDUAL MONOFILAMENTS OF A COHERED YARN. THE METHOD CONSISTS IN LIMITING THE FREEDOM OF OSCILLATORY MOVEMENT OF THE INDIVIDUAL FILAMENTS AS EXPOSED TO THE ACTION OF A COHERING GAS JET, AND IS CARRIED OUT BY PROVIDING A GROOVED OR SPLINED CYLINDRICAL SURFACE IN THE AREA WHERE THE GAS JET IS ACTIVE ON THE FILAMENTS. THE DIMENSIONS, AND THE DISTANCES AT WHICH THE CYLINDRICAL SURFACE IS PLACED WITH RESPECT TO THE OTHER COMPONENT PARTS OF THE INSTALLATION ARE CRITICAL.

A METHOD IS DISCLOSED FOR IMPROVING THE DYEABILITY OF POLYMIDE FIBRES BY ACIDIC DYES, SAID METHOD COMPRISING AS AN ESSENTIAL STEP THE ADOPTION OF A NITROGENOUS COMPOUND, WHICH CAN BE BROADLY DEFINED AS BELONGING TO THE CLASS OF BETAINES OR BETAINE-LIKE COMPOUNDS. MANY EXAMPLES ARE GIVEN, WHICH SHOW THE CRITICALLY OF THE SELECTION OF THE SUBSTITUENTS IN THE GENERAL FORMULA
