Abstract: A composite textured helically wrapped multi-filament yarn, made up of two or more continuous filament textured yarns, each of which is of different color or dyeability from the other, each yarn being pigmented in a melt-spinning process, pre-dyed, or undyed with different dye affinities which are subsequently dyed, by wrapping the colored textured yarns into a composite yarn having repeated color change alternating cycles along its length, and the alternating cycles having between them a lengthwise color difference of about 15-97% or more on the circumferential surface of the yarn in either the red, green or blue primary colors, as measured by spectral analysis, between immediately adjacent lengths thereof, and each adjacent color length being between about 4 inches to 144 inches.

Abstract: A composite textured air-entangled multi-filament yarn having two or more continuous filament feed yarns, each of which is of different color or dyeability from the other, each feed yarn being pigmented in a melt-spinning process, pre-dyed, or undyed with different dye affinities which are subsequently dyed, the feed yarns being combined into a composite yarn having repeated color change alternating cycles along its length, and the alternating cycles having between them a lengthwise color difference of about 15-95% or more on the circumferential surface of the yarn in either the red, green or blue primary colors, as measured by spectral analysis, between immediately adjacent lengths thereof, and each adjacent color length being between about 4 inches to 144 inches.

Abstract: Apparatus and method for making loop chenille type yarns and yarns produced thereby are disclosed. An elongated spindle having a tapered needle surface at one end thereof is provided. The spindle has a passage therein in communication with the needle surface for feeding a core thread to the needle surface. Effect thread is overfed to the needle location where a nose piece member cooperating with the needle aids in wrapping the effect thread about the needle to form loops. The binder yarn is fed to the needle and twisted about the core and effect threads. In a preferred embodiment, means are provided for reciprocating the nose piece relative to the needle between effect thread loop forming and effect thread non-loop forming dispositions. In this manner, "thick" and "thin" novelty yarns are provided in which the thick sections of the yarn comprise looped effect threads whereas the loops are not provided in the thin yarn sections.

Abstract: An entanglement tester, for testing the degree of entanglement of the yarns such as jet-entangled, yarn, is provided. A complex yarn path is provided, having sections arranged at angles to each other, and a measuring device is provided which may be displaced by shortening the yarn path. Means are provided for inserting a pin or needle into and through the yarn, guiding the yarn onto and off of the pin by using pivoting or sliding guides that are worked by yarn tension, and the yarn is displaced in a manner to shorten the yarn path, thus displacing the measuring device until a point of entanglement is reached. The distance between point of insertion and point of entanglement may be read out, and the measuring process repeated many times without painstaking hand guiding operations.

Abstract: A jet tangler is provided having a sharply angled passageway for the yarn and having a special air passageway arrangement which minimizes or substantially eliminates the aspiration effect encountered in jet tanglers of the prior art, especially at low tension. The tangler operates efficiently at low or high yarn tension, on texturized or as-produced yarn.

Abstract: Textile strands are transferred from a full package to an empty bobbin spaced endwise therefrom, by delaying traverse of the winding strand and by picking up the strand and forming a resulting transfer tail on the end of the empty bobbin.The pickup step utilizes rotary bristles located at the spaced adjacent ends of spindles for the respective packages.The transfer delay step may utilize a bistable inertial device positioned to intercept the transferring strand, and functioning to release the strand after a momentary delay, after which delay the strand is wound onto the empty bobbin to begin the formation of a package.The inertial device has adjustable ears and includes variable weights serving to vary the timing delay, whereby the length and position of the transfer tail may be controlled and adjusted.

Abstract: Textile strand stabilization by filament interlacing is provided by means of jet apparatus having a longitudinal strand-receiving bore intercepted by at least one fluid-receiving bore substantially perpendicular thereto and to its minor transverse axis. Fluid injected into the fluid-receiving bore establishes within the longitudinal bore a vortex-like flow configuration substantially perpendicular to the longitudinal axis and to the minor transverse axis of the longitudinal bore. The apparatus preferably has a plurality of fluid-receiving bores offset along the longitudinal axis by distances up to the width of a fluid receiving bore.

Abstract: While being fed into a laterally confining region to be retained temporarily and be compressively crimped therein, laterally spaced textile strands are traversed laterally to and fro along the entrance to the region. The resulting uneven cross-sectional distribution of crimped strand accumulation in the region is conductive to separation of individual strands upon exiting from the region.

Abstract: Textile strands are crimped by feeding them with nip rolls into and forwarding them by fluid jets within a laterally confining region terminating in a laterally surrounding fine screen.

Abstract: Package winding of textile strands uninterrupted by transfer from a full to an empty package is accomplished by delaying lateral transfer of the winding strand from a full to an empty package and by picking up a resulting transfer tail of the laterally transferring strand adjacent the end of the empty package. The transfer delay step utilizes a bistable inertial device located to intercept the laterally transferring strand and to be repositioned thereby and to release the strand after momentary inertia-induced delay during which the strand begins to wind onto the empty package. The pickup step utilizes rotary devices located at the spaced adjacent ends of spindles for the respective packages, such device on the spindle of the package to which the strand is transferring being adapted to engage and grip it. The strand is broken or otherwise severed between the pickup device and the full package, thereby enabling the strand to be traversed onto the empty package.

Abstract: Textile yarns or strands are heated, as by contact with hot rolls, and then are crimped, preferably compressively as in a stuffer crimper, after being drawn to increased length if so drawable.

Abstract: Textile strands are crimped by feeding them with nip rolls into and forwarding them by fluid jets within a laterally confining region terminating in a laterally surrounding fine screen. The resulting nip-jet stuffer-crimper is a new species of strand-crimping apparatus.

Abstract: Conveyor apparatus for temporary holdup of textile strands, especially crimped strands for setting. Screenlike conveyor belts receive the strand between downwardly converging flights and discharge the strand from between upwardly diverging flights. The conveyor apparatus is housed in a heated steam-fed enclosure.

Abstract: Surface wetting of scored textile film strands facilitates fibrillation thereof. Liquid water of inert aqueous solution is applied by various means in the form of droplets or a thin surface layer to such strands, which then are compressed laterally and longitudinally to fibrillate and crimp them, as by stuffer crimping, in a continuous process optionally including predrawing the strands to increased length.

Abstract: Textile strands are compressively crimped by propelling them lengthwise, as by a fluid jet, into a rotating cylindrical chamber having a foraminous surface. Rotation of the chamber aids in collection and temporary retention of the crimped strand until it is withdrawn therefrom at the leading edge of the strand accumulation after about half a revolution. The crimped strand is withdrawn between an edge of the chamber and an adjacent solid surface rotating therewith, as by conical rolls.
