Abstract: Jet using high pressured gaseous fluid to partially fracture yarn and to entangle the yarn, the jet being a significant improvement over the jet disclosed in the Dyer patent, U.S. 2,924,868, which has a housing provided with a gas inlet, a yarn guiding needle, orifice plate, and venturi; the improvement including reducing the size of the passageways through the needle, orifice plate and venturi, and selectively providing the inward taper of the outer wall of the yarn guiding needle inner end portion with a half angle of about 15.degree. relative to the axis of the needle yarn guiding passageway, providing the wall of the orifice plate entry opening with an inwardly tapering bevel of about 30.degree. relative to the axis of the entry opening, and providing the diverging wall portion of the venturi exit opening with a half angle of about 2.5.degree. relative to the venturi axis.

Abstract: Method and apparatus for practicing the method by which the loose end of yarn, which extends between the tube notch where the yarn becomes snagged and retained and the point in or near the air doffer where the yarn becomes snapped and severed, in the manner described in the Newman et al U.S. Pat. No. 3,971,518 and in the Spaller U.S. Pat. No. 3,999,716, is trapped and wound up on a pin projecting from the outer axial end of the winder mandrel, thus preventing any possible interference of the loose yarn end with the subsequent formation of a transfer tail on the yarn package tube and/or the winding of the package portion on the yarn package tube.

Abstract: Improved method, and apparatus for practicing the method, for determining parameters of a staple length distribution of fibers in a yarn sliver by feeding the yarn sliver to and between two pairs of drafting rolls initially spaced apart at a greater distance than the longest fiber in the yarn sliver and monitoring the drafting force exerted upon the yarn sliver while continuously decreasing the distance between the pairs of drafting rolls and monitoring the distance, and generating signals representative of the drafting force and distance and feeding them, respectively, to the Y-axis and X-axis of a X-Y recorder and drawing a curve therefrom from which the desired parameters can be determined.

Abstract: Tobacco smoke filter rods made with fibers selected from cellulose acetate, poly(ethylene terephthalate) and poly(hexamethylene adipamide) bonded with water and glycol bonding dispersions comprising water, high boiling glycols selected from 1,2-propanediol, 1,3-propanediol, 1,4-butanediol, 1,2-butanediol and 1,3-butanediol; and water and glycol dispersible polyester polymers. The polymer is present in the amount of about 5 to 40% by weight of the dispersion and preferably about 15 to 35% by weight, and is selected from polyesters of combinations of isophthalic acid and the sodium, potassium, or lithium salt of sulfoisophthalic acid reacted with diethylene glycol or triethylene glycol; and from terephthalic acid and the sodium, potassium or lithium salt of sulfoisophthalic acid reacted with diethylene glycol or triethylene glycol. The water and selected glycol(s) serve as a carrier or dispersion medium for the selected water and glycol dispersible polymer. The dispersions contain from about 0.

Abstract: Process for making producer-colored fibers, yarns, films and related products by extruding from a source, such as from an extruder, a flow of polymer to a spinneret placing in the path of flow between the polymer flow and the spinneret a dye solid or pigment solid having a predetermined shaped surface area, and flowing the polymer into contact against the exposed surface of the dye solid or pigment solid and by such contact dissolving at a predetermined rate a predetermined portion of the dye solid or pigment solid into the polymer flow and coloring the polymer flow for subsequent extrusion from the spinneret as colored filaments.

Abstract: Process and product obtained by the process by which an undrawn or partially drawn continuous filament yarn is heated above glass transition temperature and is differentially drafted by co-current and countercurrent heated gaseous flows to form in the filaments at random intervals along the lengths of the individual filaments coils, loops or whorls, with more drafting occurring in those portions of the filaments having the coils, loops or whorls than the other portions, and with more drafting occurring in some loops than others, and at the same time heat setting the yarn within the heated gaseous flows.

Abstract: Process and product obtained by the process by which an undrawn or partially drawn continuous filament yarn serving as an effect yarn component and a continuous filament yarn having a greater orientation than the effect yarn component and serving as a core yarn component are heated above glass transition temperature by co-current and counter-current heated gaseous flows to form in the filaments of the effect yarn component at random intervals along the lengths of the individual filaments coils, loops or whorls, with more drafting occurring in those portions of the filaments having the coils, loops or whorls than the other portions, and with more drafting occurring in some loops than others; intermingling the effect yarn component with the core yarn component, and at the same time heat setting the yarn components within the heated gaseous flows.

Abstract: Apparatus for assisting an operator in doffing a yarn package from a textile winder, the yarn being wound on a hollow tube; the hollow tube in turn being mounted on and rotatively locked on a winding mandrel of the winder and having an end portion of the tube extending axially outwardly of the end of the winding mandrel. The apparatus comprises an abutting member for insertion within the extending tube end portion for abutment against the winding mandrel end and a series of gripping members concentric with the abutting member and actuatable for expanding radially outwardly into gripping engagement with the inside surface of the tube end portion.

Abstract: Water and glycol bonding dispersion comprising water, high boiling glycols selected from 1,2-propanediol, 1,3-propanediol, 1,4-butanediol, 1,2-butanediol and 1,3-butanediol; and water and glycol dispersible polyester polymers. The polymer is present in the amount of about 5 to 40% by weight of the dispersion and preferably about 15 to 35% by weight, and is selected from polyesters of combinations of isophthalic acid and the sodium, potassium, or lithium salt of sulfoisophthalic acid reacted with diethylene glycol or triethylene glycol; and from terephthalic acid and the sodium, potassium or lithium salt of sulfoisophthalic acid reacted with diethylene glycol or triethylene glycol. The water and selected glycol(s) serve as a carrier or dispersion medium for the selected water and glycol dispersible polymer. The dispersions contain from about 0.1-20% water by weight.

Abstract: Method for melt spinning from inelastic materials extruded lengths of predetermined cross-sections from predetermined arrangements in spinnerets of non-round orifices having one axis or no axis of symmetry in the plane of the spinneret face, and to such arrangements of two or more such spinning orifices in spinnerets for practice of the method by which non-axisymmetric emergence behavior, i.e., "kneeing," of inelastic fluid streams from spinnerets is utilized. Each non-round orifice in the arrangement has a significant kneeing potential of greater than (.+-.) 0.1, and preferably greater than (.+-.) 0.

Abstract: Transfer tail apparatus for use with a yarn winder on which the yarn package tube has at its outer axial end an end slit or other yarn snagging means for snagging and retaining yarn during tie-up, the transfer tail apparatus having a first yarn guide adapted to move in a path and translate a continuously moving yarn into engagement with the tube end slit or other yarn snagging means; and a second yarn guide operative after such snagging and adapted to guide the snagged yarn into a waste bunch and then move in a path and guide the yarn into spaced helical wraps constituting the transfer tail, after which the second yarn guide releases the yarn for subsequent pickup by a yarn traverse guide on the yarn winder for forming the package portion on the yarn package tube.
