Abstract: A system for forming elastomeric core/staple fiber wrap yarn using a spinning machine such as an air jet, roller jet or roller spinning machine. The system includes a package drive assembly, yarn motion and presence sensors, an improved drafting assembly and a yarn clearer delay cylinder to provide continuous formation of superior quality elastomeric core/wrap yarn.

Abstract: A low-density, substantially cylindrical, wound package of substantially tensionless, low modulus, highly elastic yarn, preferably having a density of not greater than about 0.300 g/cc. Such packages are made by advancing tensionless yarn through a traversing mechanism in a stream of fluid which is moving in the same direction as the yarn and at a speed greater than the linear speed of the yarn being taken-up on the cylindrical package. Such packages are produced on apparatus for tensionless traversing of yarn wherein the yarn guide on the traversing end of the traversing element comprises the outlet of a fluid jet through which fluid is driven to maintain the tensionless condition of the yarn as it passes through the traversing element and is thereafter wound into a low density, tensionless package.

Abstract: A system for eliminating odors by using an odor scavenger member having a textile substrate or the like impregnated with odor scavenging materials such as N-trisubstituted ammonium-2-hydroxy-3-halopropryl compounds or salts of epoxy propyl ammonium compounds such as glycidyltrimethylammonium chloride. Such members, and the methods of making and using same are included.

Abstract: A system for controlling extraneous free flowing dyes or colorants in a liquid bath by using a dye scavenger member having a textile substrate or the like impregnated with a dye scavenging material such as N-trisubstituted ammonium 2 hydroxy 3 halopropryl compounds or salts of epoxy propyl ammonium compounds such as glycidyltrimethylammonium chloride. Such members, and the methods of making and using same are included.

Abstract: A system for preventing static cling among textile materials such as clothes in a washer by using in a liquid bath containing the textile materials a static preventing member having a textile substrate or the like reacted with a static preventing material such as N-trisubstituted ammonium 2 hydroxy 3 halopropryl compounds or salts of epoxy propyl ammonium compounds such as glycidyltrimethylammonium chloride. Such static preventing members, and the methods of making and using same are included.

Abstract: An aero-mechanical open-end spinning machine, in which feedstock fibers pass between the teeth of the combing roller and the teeth of a combing sector facing the combing roller, and are thereby paralleled prior to their entry into the air stream by which they are delivered to the spinning rotor.

Abstract: A system for ammoniating and curing flame-retardant impregnated single textile yarns by steps including impregnating the yarn with THPOH, drying the impregnated yarn, and ammoniating the THPOH-impregnated yarn by passing a single end of the yarn through a small tube leading into an ammoniation chamber wherein there is located a spool and means for rotating said spool for winding the ammoniated yarn onto the spool, the small tube being reciprocatable to traverse the length of the spool for uniformly winding the yarn on the spool.

Abstract: An aero-mechanical open-end spinning machine including spinning rotor cleaning means such as a fibrous brush or air jet for continuously agitating any foreign matter on the interior surface of the spinning rotor so that same may exit in the airstream accompanying the open-end spun yarn.

Abstract: A flame-retardant yarn or thread containing a flame-retardant lubricant which consists of one or more mono- or di-chloro alkanes or one or more mono- or di-bromo alkanes, wherein the alkanes have ten to thirty carbon atoms.

Abstract: Apparatus for blending, paralleling and cleaning fibers such as cotton and synthetics. The apparatus comprises a work roll having its surface covered with metallic wire and an arcuate, metallic wire section cooperating with a portion of the periphery of the work roll. The fiber is fed between the roll and arcuate surface, accomplishing the improved results noted in the accompanying specification.

Abstract: A flame-retardant yarn or thread containing a flame-retardant lubricant which consists of one or more mono- or di-chloro alkanes or one or more mono- or di-bromo alkanes, wherein the alkanes have ten to 30 carbon atoms.

Abstract: A flame-retardant yarn or thread containing a flame retardant lubricant, which is a brominated ester of oleic or linoleic acid, is disclosed. The esters are brominated at those portions of the ester having original ethylenic unsaturation and function both as a lubricant and a flame retardant.

Abstract: Disclosed is a method and apparatus for removing a filler thread from a multiple end yarn tape. The yarn tape containing a filler thread is passed over an elongated framework which defines a filler thread removal region. In this region the filler thread is removed from the tape and taken up on a Gilbos winder. The yarn ends are separated downstream of the removal region and wound up on separate take-up spools resting on pairs of driven rollers; the take-up spools are frictionally driven by the positively driven rollers. Means are provided to adjust the speed of the Gilbos winder relative to the yarn tape speed to maintain the removal point of the filler thread from the tape within the defined thread removal region. Further means are provided to shut down the entire apparatus when a break in the filler thread being removed from the yarn tape is detected.
