Abstract: A fabric includes mutually transverse thread systems, with at least one of the thread systems including a differential shrinkage yarn C. The shrinkage yarn C has at least one effect component A that irreversibly elongates itself upon heat treatment, and at least one shrinkage component B that shortens itself upon heat treatment. The components A and B are bound together by nodes, wherein the number (y) of nodes per meter in the yarn C is predetermined as a function of the yarn count (x) of the transverse thread system so that the number (y) of nodes exceeds a minimum value and increases proportionally above the minimum value as a function of the yarn count (x).

Abstract: A process for imparting antimicrobial properties to textile fabrics by applying an antimicrobial substance to the fibers from which the textile is woven, knit or constructed. Preferably the antimicrobial substance is applied, prior to weaving, to warp yarns on a slasher or warper or similar coating or finish application device before the warp ends are rolled up onto a loom or section beam. The warp yarns are then woven with fill yarns, not treated with the antimicrobial, into a cloth which is then sold in the loom state or subjected to subsequent finishing. A preferred cloth end use is mattress ticking.

Abstract: A textile yarn slashing system having a foam applicator disposed therein for pre-wetting the sheet of yarns prior to passing through the size box. The foam is delivered under pressure and a resilient hold down member opposes the slot to create a space for foam on the opposite side of the yarn sheet from the slot for application of foam to both sides of the yarn sheet. A flexible cover sheet covers the surface of the hold down member and is shifted to replace a worn portion with an unworn portion opposite the slot. A valve assembly is incorporated in the applicator to close off the passage to the slot and permit bypass flow of the foam. End seal blocks have rigid metallic outer chamber engaging surfaces and resilient material interior of the surfaces to press the surfaces against the sides of the chamber adjacent the slot. A plurality of horizontal tubes may be used as an alternate to the slot with one or more yarns traveling through each tube.

Abstract: In a method and apparatus for sizing a yarn sheet, the yarn sheet is passed over rollers through a wetting unit and a following roller nip that reduces the moisture content to a selected level. The wetted yarn sheet then passes through a sizing unit and over rollers forming a nip to reduce the sizing content to a desired level. The rollers of the wetting unit and the rollers of the sizing unit are in close proximity to minimize the reach of the yarn sheet there between and thereby minimize the heat loss in the yarn sheet. The reach is covered by a cover having a heater that extends over the yarn sheet reach to maintain the yarn sheet at a desired temperature as it enters the sizing unit. The temperature of the wetting agent bath in the wetting unit is 65°-95° C., with the temperature of the wetting agent being approximately 5°-10° C. higher than the temperature of the sizing agent bath.

Abstract: Spun yarns are subjected to the vortex action of an impinging, circularly rotating fluid to lay down extending staple fibers against the yarn body while causing the yarn path to balloon and are then contacted with a melt size presented on a slower moving grooved melt size applicator. As a result of the ballooned yarn path, the yarn wipes melt size from the sides and bottom of the groove, giving the yarn a smooth, substantially continuous coating on its outside surface. Spun yarns so treated may be successfully woven as filling yarn on a water jet loom and knit as the warp yarn or as laid-in yarns on a knitting machine without excessive lint accumulation.

Abstract: An apparatus and method for sizing warp yarn utilized in preparing a loom beam for weaving are disclosed. A porous application roll (A) is utilized for applying a sizing material onto a sheet of warp yarns (12) passing between a pressure roll (30) and the application roll. The application roll includes a continuous cylindrical porous application surface (B) formed around the entire periphery of the roll having an extent at least as great as the warp yarn sheet width. An intermediate porous distribution layer (C) is provided next to the application surface (B) for disbursing the sizing material onto the application surface. A porous flow control membrane (D) having a pore size less than that of the distribution layer occupies a boundary region for metering the sizing material. When the passage of warp yarns is discontinued, the application roll (A) is moved to an idle position by an actuator (38). In the idle position, liquid (72) is made to contact the application surface to maintain it in a moist condition.
