Polyester carpets of poly(trimethylene terephthalate) are disclosed which have excellent stain-resistance, texture retention and resistance to crushing. The bulked continuous filament yarn used to make the carpets and the process for making the yarns are also disclosed.
摘要:
A steel cord for radial tires having a “2+5” construction structured by twisting a core and a strand in such a fashion that they have the same twist pitch length and the same twist direction, so that the number of processing steps for the twisting process is reduced from two to one, thereby reducing the manufacturing costs while achieving an improvement in productivity.

A wind tunnel blade (30) connected to a base (32) and held in position by a two-piece cuff (34). The wind tunnel blade (30) is formed in a resin transfer molding process in which central, fore, and aft foam core sections (70, 72, 74) are placed together to form the wind tunnel blade (30). Radius fillers (120) are used to fill the gaps between the outer edge of the foam core sections. The radius fillers (120) used in the wind tunnel blade (30) are formed by a braided sleeve (122) surrounding a number of unidirectional tows (124). A tip (68) is formed separately from the rest of the wind tunnel blade (30) and is glued to the top thereof Stacked layers of braided fibers (100) are used to reinforce the central core section (70).

An apparatus and method for producing a core spun yarn by means of a fluid delivery device is provided. The apparatus substantially comprises a fiber and thread guide means using a fiber guide conduit with a fiber guide surface for guiding fibers and a thread guide for guiding at least one continuous yarn into an inlet orifice of a yarn guide conduit and a fluid delivery device for producing a swirl flow about the inlet orifice of the yarn guide conduit so that the at least one continuous yarn can be spun over by the fibers. The thread guide is either a groove which is associated with the fiber guide surface, a bore disposed below the fiber guide surface, an individual tube-like element, or a tube-like element that is combined with a groove or a bore. The thread guide is introduced in a fiber and thread guide means, with the axis of the groove, the bore or the tube-like element being in alignment with the axis of the yarn guide conduit.

An expanded graphite knitting yarn according to the present invention is covered or bound and covered with a reinforcing material made of a braided body such as stainless steel line members, before an outer periphery of an expanded graphite tape having a predetermined width, which has been subjected to a twisting process, is braided. Therefore, an amount of the expanded graphite particles exfoliated from ends of the expanded graphite tape in the twisting process can be significantly reduced. Moreover, this can prevent the expanded graphite particles from being exfoliated from the end of the expanded graphite tape in a braiding process. Furthermore, the plural expanded graphite knitting yarns are put together and subjected to either braiding or twisting process, thereby forming a gland packing. This can enhance a sealing property and a pressure resistance property of the gland packing.
摘要:
A new insulated wire resists heat cycles under severe operating ambient temperatures without reducing the lifetime of coils in which the insulated wire is used. The insulated wire has on the insulating coating a fluororesin coating without or with a binder constituting 20 wt. % or less. The fluororesin coating comprises fluororesin such as polytetrafluoroethylene, a tetrafluoroethylene-perfluoroalkylvinylether copolymer, or a fluoroethylene-propylene copolymer.
摘要:
A filler element is located between each adjacent pair of outer strands of a wire rope and interlocks with the adjacent strands. The filler elements provide the rope with substantially smooth outer surface reducing vibration of the rope passing over a pulley. Filler elements are disclosed consisting of an elastometic or polymeric material having an oriented molecular structure aligned along the filler element and also aligned in a generally radial direction with respect to the rope.
摘要:
A novel and superior lariat and lariat rope body for calf and steer roping having a core of monofilaments in the center around which three or more strands of twisted monofilament yarns are wound tightly to form the rope. A novel method of making lariat rope bodies and apparatus used are also disclosed. The rope body has a core in at least about 68 percent of the length of the rope body beginning with the honda end.
摘要:
Rovings 30A and 30B as drafted are, under a parallel condition, passed through a collector 16, twisted and wounded from front rollers 12-1 and 12-2. A core yarn 34 is, via a guide member 40 as a snail wire, introduced into rovings 30A and 30B from the rear side of the front rollers. Since the guide member 40 is fixedly connected to the collector 16, the guide member 40 can follow with the lateral displacement of the collector 16, so that a central feed of the core yarn 34 to the rovings 30A and 30B is maintained, thereby always keeping a condition that the core 34 is fully covered by the outer fibers.
摘要:
A wire rope is disclosed, which has at most 18 outer strands and an independent wire rope core, with the strands of the core being laid in the opposite direction to the outer strands of the rope, and a nylon jacket is provided between the core and the outer strands of the wire rope.
