    Abstract: Flat continuous multifilament nylon apparel yarns suitable for critical dye applications and a process for making such yarns. The process for making the yarns includes spinning nylon polymer with a relative viscosity between about 35 and about 80 and stabilizing to make a feed yarn. The withdrawal speed in spinning is sufficiently high that highly uniform feed yarns are provided. In the process, feed yarn is drawn and subsequently relaxed, preferably in the form of a warp of yarns, so that the resulting drawn yarns have properties suitable for use as flat yarns and have excellent dye uniformity with large molecule acid dyes.

    Abstract: A process for making a heather-dyeable or precolored heather yarn product comprises supplying a first crimped continuous filament yarn in the form of a loose matrix substantially free of filament entanglement and a second crimped continuous filament yarn which is differentially dyeable or precolored with respect to the first yarn. The second yarn is fed through a first entangling or interlacing zone and exposure of the second yarn to a fluid jet in the first entangling zone is randomly controlled to produce a color-point yarn product as the second yarn exits the first entangling zone, in which the color-point yarn product has relatively compact nodal regions of high entanglement of the filaments of the second yarn separated by bulkier regions of the same filaments relatively free of entanglement. The first yarn and the color-point yarn product are then fed through a second entangling zone which randomly entangles filaments of the yarns from yarn to yarn and in which yarn-to-yarn filament commingling is substantially prevented within the nodal regions of the color-point yarn. An apparatus for performing the process includes a randomly controllable fluid valve supplying fluid to the fluid jet in one embodiment, and a randomly controllable yarn guide to move the yarn into and out of the fluid jet in another embodiment.

    Abstract: Potential bulky polyester associated bundles or yarns for woven or knitted fabric include spontaneously heat extensible multi-filament A and heat shrinkable multi-filament B. The associated bundles are interlaced at 20-100 interlaces/m. For multi-filament A, the following physical properties apply: 4 g/denier, denier ratio of 80-29% content in associated bundles, SHW (B)>5-60%. Additionally, SHD (B)-SHD(A)>5%. The invention also relates to processes for forming the bundles and for weaving the bundles into fabric.

    Abstract: Interlacing means are provided for the interlacing of multifilament yarns exhibiting a yarn channel. At given distances from the entrance and exit openings forming the yarn channel, yarn guides are so arranged that, with the supply of compressed air shut off, the yarn is laid onto the yarn channel so that it extends parallel to its longitudinal direction, and that the straight yarn sections, which are located between the entrance and exit openings of the yarn channel and the yarn guides, are inclined at acute angles to portions of the geometric longitudinal axis of the yarn channel. Furthermore, the blow angle of the blow nozzle is smaller than 90.degree.. The length of the yarn channel equals for smooth yarns maximally 40 mm and for texturized yarns maximally 30 mm. There results exceptionally high yarn advance speeds and a particularly good vortexing of the yarn.

    Abstract: This invention relates to an apparatus and a process involving fluid jet devices for intermingling filaments of a continuous filament yarn or yarns, including combining a plurality of yarns to produce a larger coherent yarn. More particularly, the invention relates to fluid jets having a passageway through which yarn moves, where the yarn is positioned and maintained along one wall as it passes through the passageway and where the fluid-directing orifice in the jet is offset with respect to the passageway in the direction of the wall. The apparatus and the process are useful in producing heather yarns with superior yarn blending and along-end uniformity.
