    Abstract: NOVEL AZIRIDINE DERIVATIVES OF THE FORMULA:

    1-R1,2,5-DI(O=),3-(2-R-AZIRIDIN-1-YL)PYRROLIDINE

    WHEREIN R IS HYDROGEN OR METHYL AND R1 IS HYDROGEN, METHYL, PHENYL OR A RADICAL OF THE FORMULA:

    (2,5-DI(O=),3-(2-R-AZIRIDIN-1-YL)PYRROLIDIN-1-YL)-R"-

    WHEREIN R IS A DEFINED ABOVE AND R'' IS AN ALKYLENE RADICAL OF 2 TO 12 CARBONATOMS OR TWO PHENYLENE RESIDUES BONDED TO ONE ANOTHER BY -CH2-, -SO2- OR -O- ARE PRODUCED BY REACTING STOICHIOMETRIC AMOUNTS OF AN UNSATURATED DICARBOXYLIC ACID IMIDE OF THE FORMULA:

    1-R2,2,5-DI(O=)-3-PYRROLINE

    WHEREIN R2 IS HYDROGEN, METHYL, PHENYL OR A RADICAL OF THE FORMULA:

    (2,5-DI(O=)-3-PYRROLIN-1-YL)-R"-

    WHEREIN R" IS AS DEFINED ABOVE WITH AN AZIRIDINE OF THE FORMULA:

    2-R-AZIRIDINE

    WHEREIN R IS DEFINED ABOVE AT A TEMPERATURE OF 20 TO 200*C. FOR 10 MINUTES TO 10 HOURS IN THE PRESENCE OR ABSENCE OF A SOLVENT. NOVEL RETICULATED POLYMERS ARE PREPARED FROM THESE NOVEL AZIRIDINE DERIVATIVES BY POLYMERIZING SAID AZIRIDINE DERIVATIVES. THE POLYMERIZATION PROCESS COMPRISES HEATING THE AZIRIDINE DERIVATIVE TO A TEMPERATURE BETWEEN 50 TO 200*C. AND THE RETICULATED POLYMER PRODUCED THEREBY IS CHARACTERIZED BY RECURRING STRUCTURAL UNITS WHICH ARE CONNECTED TO ONE ANOTHER THROUGH AMIDE LINKAGES AND HAVING THE FORMULA:

    -N(-CH(-R)-CH2-)-CH(-CH2-CO-)-CO-N(-R4)-

    WHEREIN R IS DEFINED ABOVE AND R4 IS HYDROGEN, METHYL, PHENYL OR A PENTAVALENT RADICAL OF THE FORMULA:

    -N(-R"-)-CO-CH(-CH2-CO-)-N(-CH(-R)-CH2-)-

    WHEREIN R AND R" ARE AS DEFINED ABOVE; AND WHEN R4 IS SAID PENTAVALENT RADICAL IT IS ATTACHED TO THE REST OF THE RECURRING STRUCTURAL UNIT THROUGH THE R" PORTION THEREOF.

    CPC classification number: D01D5/253

    Abstract: The invention discloses a spinneret for producing a trilobal filament, and filaments produced using such spinneret. The shape of each orifice of the spinneret can be considered as being produced by a circular aperture, diameter D into which project at 120* intervals, three identical triangular portions, sides of the triangles being tangent to one or more coaxial circles having a diameter between one-sixth and one-third of D, the angle at the apex of each triangle being between 60* and 100*.

    Abstract: A double-twist spindle for doubling a yarn in which an integral shaft and rotor rotate with respect to a stator, which is magnetically held against rotation and carries a spool of yarn. An axial and a radial passage in the shaft and rotor respectively join in the rotor at the location of a removable, normally fixed yarn guide.

    IPC: D02J1/00 ,  D02G1/16

    CPC classification number: D02G1/16

    Abstract: A loose bundle of fibers is passed through a new nozzle, characterized by a conduit provided with at least two slots and means for directing a fluid, for instance air, tangentially to the conduit for the fibers. Part of the fibers becomes transversely arranged over the remainder of the fibers giving a strong wound-up unit, which cannot be spread apart. Fixed points at regular intervals are obtained.

    Abstract: CELLULOSE-2 1/2-ACETATE TEXTILE OR KNITTED FABRICS ARE MADE BY WETTING THE RAW MATERIALS; TREATING THEM AT ROOM TEMPERATURE AT A BATH RATIO OF BETWEEN 1:3 TO 1:10 IN A LYE SOLUTION WITH SLOWLY RINSING ALKALI CONENT WHICH IS FIRST RAISED UP TO ONLY 2% OF THE MATERIAL WEIGHT INTRODUCED. THE LYE SOLUTION IS THEN HEATED TO 80-100*C.; TREATING THE PRODUCT AGAIN IN A LYE SOLUTION WITH THE ALKALI CONTENT BEING SLOWLY INCREASED TO 4-5% OF THE INTRODUCED RAW MATERIAL WEIGHT, SO THAT THE SAPONIFICATION IS ONLY ON THE SURFACE.
