Abstract:
A fabric is constructed by weaving on a loom, with a loom setting of between about 78%-88% of firm setting in the greige, using false twist textured polyester warp yarn with about 57-75 ends per inch and air textured polyester weft yarn with about 36-54 picks per inch, and finishing the fabric by scouring (on a jet or on a continuous scouring range) and printing or jet dyeing, and then heat setting at temperature of at least about 350null F. The yarns may be fire resistant (FR), or finished with a durable FR finish. The fabric scores between 4.5 and 5.0 on each of random tumble pilling, brush pilling, and Klopman method roughing and pilling, tests. The fabric also has a surface SMD of at least about 4.3, a bending rigidity 2HB of about 0.1 or less, a compressibility EMC % of less than about 28, a shearing stiffness G value of about 2 or less, and an extensibility EMT % of at least about 3.0. The fabric is especially suitable in the hospitality trade, e.g. for curtains and bedspreads.
Abstract:
A ballistic vest having ballistic members which are positioned in the front and rear of the torso of a person each member having a plurality of layers of alternately spaced woven fabric sheets of (1) ballistic nylon fiber and (2) aramid fiber. The members are contained within envelopes which are fastened together so as to be draped over the shoulders of the wearer and held in position around the torso by means of a plurality of straps.
Abstract:
An apparatus for progressively longitudinally slitting a tubular knitted fabric on a knitting machine as the fabric is progressively knitted during the operation of the machine prior to being wound up into a roll thereon so as to produce a wound up strip of knitted fabric folded lengthwise upon itself.
Abstract:
The present invention provides a simple assembly easily installable on a specific type of circular knitting machine, with substantially no modification thereof, for actuating a vertically-reciprocable non-rotating fabric-receiving slitter control tube disposed within the needle cylinder of the machine for operating a slitter mechanism at the upper end of the cylinder. The assembly also rotatingly drives a fabric-receiving suction draw-off or accumulator tube coaxially aligned beneath the control tube in synchronism with the needle cylinder for preventing twisting of long lengths of tubular fabrics knitted on the machine.
Abstract:
Improvements in a conventional false-twist texturing process are disclosed which produce textured polyester yarn of improved quality (compared with that produced by conventional false-twist texturing) of the type obtained by known draw-texturing processes without the unstable feed yarn problems and feed yarn rupturing at start-up (and hence apparatus modification) problems incident thereto. The improvements comprise utilizing as the feed yarn in a conventional false-twist texturing process, a polyester yarn having (1) a spin-drawn orientation, free of mechanically-drawn orientation, with a birefringence within a range of the order of 0.02 to 012, (2) a percentage elongation-to-break within a range of the order of 60% to 200%, and (3) a zero-strength temperatue above approximately 235*C; and continuously positively feeding the feed yarn into and out of the texturing zone provided by the apparatus in performing the process, while maintaining the twistsetting temperature or heater temperature of the apparatus below the zero-stength temperature of the feed yarn, at feed rates into and out of the texturing zone in accordance with the formula DR > (OR) (EB/100 + 1)) wherein DR is the feed rate of the feed yarn out of the texturing zone divided by the feed rate into the texturing zone, or is a constant within a range of the order of 0.63 to 0.70, and EB is percentage elongation-to-break of the feed yarn.
Abstract:
Flame retardants for cellulosic fabrics, especially polyester blends, comprise a limited phosphine oxide class of N-methylol propionamides, particularly N-methylol-3(dimethylphosphinyl)propionamide, closely related structurally to N-methylol-3-(dimethyl phosphono)propionamide, but markedly more effective as a flame retardant.
Abstract:
A system for transferring information from a plurality of data stations to a central station such as a computer. A novel data controller couples the computer to a plurality of master stations, some of which may in turn be coupled to a set of slave stations, for communicating with the master stations. The data controller operates in three phases - a load phase in which a station address and instructions are loaded into the controller either from the computer or an internal memory within the data controller, an execute phase in which the data controller communicates with the addressed stations and a transfer phase in which the received information is transferred by the data controller to the computer or, if it is malfunctioning, to auxiliary storage devices. Any of a number of unique master stations can be used in the system. A slave multiplexer operates to interrogate a number of associated slave stations of varying types and convey the information thus derived to the data controller when queried. An interactive keyboard permits manual entry of information which is then conveyed to the data controller.
Abstract:
A fabric suitable for V-belt covers and hose reinforcing is made by bias-cutting a tubular woven fabric into a continuous strip, stretching the continuous strip in the width direction as with a pin tenter frame to increase the angle between warp and filling to greater than 90*, applying an elastomeric coating, and longitudinally slitting the strip into a plurality of narrower tapes which are then wrapped around a V-belt core in a conventional manner or used as hose reinforcing.
Abstract:
Finished, form-fitting garments, having limb openings conforming to the shape of the human torso, are automatically and continuously made at high speed by means of torso contoured forms moving along a path. The sheet material is printed with an adhesive seam pattern, if desired, formed into a tube, cut into tubular garment blanks and crotch patches adhered when the garments are panties. The blanks are individually and successively fed onto the forms, accurate limb openings cut at one station, elastic bands added, if desired, and enclosed in tubular edge seams at other stations and the finished garments inverted and stripped from the forms.
Abstract:
The adhesion of carboxylated SBR adhesive to polypropylene carpet backings is improved by a coating on the polypropylene of chlorinated polypropylene having a chlorine content of 10-20%.
