A yarn having good entanglement and good quality, preferably a multifilament polyamide yarn, a method for making the yarn, and a woven fabric made from the yarn wherein the yarn comprises the following properties: the yarn length per defect is greater than or equal to about 3000 meters per defect; the maximum skip length is less than or equal to about 120 millimeters; the ratio between yarn length per defect to maximum skip length is greater than or equal to about 50; the entanglements per meter times the average entanglement strength is greater than or equal to about 120; and the yarn can be woven sizeless. The yarn of the invention is useful in the sizeless weaving of fabric used in air bags.

The weft threads (14) of a textile product (10) run at an angle of at least approximately 70 degrees with respect to its warp threads (12) and the weft threads (14) protrude, by a piece, beyond the outermost warp threads (12′), on at least one side of the strip-shaped textile product (10) in a strip-shaped textile product (10), consisting, in particular, of filaments, threads, or a yarn, for use as a reinforcement layer for hoses, tubes, pressure containers, and similar hollow objects. Alternately or in addition, the warp threads (12) are formed thinner than the remaining warp threads (12) in at least one boundary area (R) of the textile product (10).

An improved thermally stable, storage stable gas generating composition characterized by both an increased burning rate and a decreased pressure exponent for producing a clean, nontoxic, substantially ash- and solids-free gas for inflating inflatable structures such as vehicle airbags is provided. Optimum combustion efficiencies and operating pressures are achieved in the improved gas generating composition by adding an effective amount of a copper or copper compound catalyst to a gas generating composition that is preferably a eutectic mixture or solid solution of ammonium nitrate, at least one highly oxygenated fuel, potassium or cesium perchlorate or nitrate and an optional binder.

The machine felt includes an insert having two sides and two ends, a layer of aligned longitudinal threads enclosing the two sides and two ends of the insert and coupling eyes formed by the layer of aligned longitudinal threads enclosing the two ends of the insert. The insert is enclosed by folding the layer of aligned longitudinal threads over the insert or by placing the insert within the layer of aligned longitudinal threads having a cylindrical configuration.

A fabric comprising a blend of at least one polyester fiber and at least one elastic fiber for making postoperative garments, athletic garments, and other garments where it is desirable to provide for enhanced muscular support, performance, injury prevention, and comfort. The fabric has an elasticity of about 200-220±10% in both the warp direction and in the fill direction, the difference between the warp and fill direction elasticity preferably being no more than about 3% to about 5%, a compression modulus of about 1 to about 4, and a breathability measurement of 70-100% moisture loss within 30 minutes and an approximate skin surface temperature reduction of about 4-6° F. within about 3-7 minutes as measured by evaporative cooling, and the panels being attachable to each other along one edge by a closure means, such as mated hook and loop fasteners. The improved universal compression characteristics, breathability and thermoregulation provide enhanced ability to promote healing and protect the wound site.
摘要:
A temporary surface covering with a woven structure formed of warp threads and weft threads and whose weave is such that each warp thread intersects or intertwines with the following weft threads, and a second auxiliary woven structure being superposed having a layer of warp threads and a layer of weft threads, the connection between the two woven structures being carried out in the course of a same weaving operation simultaneously with the overlapping of the structures, so as to constitute between the two structures, from place to place, tubular pockets oriented in the direction of the warp threads or in the direction of the weft threads, the pockets serving for the reception of elements devoted to various uses.
摘要:
Preferred gas generant compositions incorporate a combination of 5-aminotetrazole nitrate and an oxidizer. The oxidizer may be selected from a group including nonmetal and metal nitrates, nitrites, chlorates, chlorites, perchlorates, and oxides. 5-aminotetrazole nitrate is characterized as an oxygen-rich fuel and is therefore considered to be a self-deflagrating fuel. To tailor the oxygen balance in certain applications, however, the use of an oxidizer is preferred. Methods of formulating the compositions are also described. These compositions are especially suitable for inflating air bags and actuating seatbelt pretensioners in passenger-restraint devices.

A woven carpet backing may include monofilament warp yarns and alternating monofilament and multifilament fill yarns. The yarns may be woven using a weave, such as a non-traditional weave, that places all of the multifilament fill yarns on the face of the fabric and all of the monofilament fill yarns on the back of the fabric. Monofilament fill yarns and multifilament fill yarns are overstuffed, thereby creating a coverage factor greater than one hundred percent. The invention results in a carpet backing with the appearance of a primary carpet backing on one side of the fabric and the appearance of a secondary carpet backing on the opposite side of the fabric. The need for a secondary carpet backing is eliminated by the woven carpet backing.
摘要:
A woven preform for a ceramic composite has a plurality of layers and structural members. The plurality of layer are of woven yarns of fibrous material. The structural members extend between the layers. The layers and members define interlayer spaces. One or more of the layers may have a plurality of openings extending therethrough. Low density ceramic insulation made be deposited in the interlayer spaces via a slurry that enters the preform, or the preform after it has been made a part of a composite, through the openings. The carrier of the slurry exits the preform, leaving the randomly packed fibers in the interlayer spaces. The structural members may be walls that, along with the layers, define channels. The channels may be used to direct fluid through so as the composite functions as an insulator. The channels may be directed in the warp direction for achieving increased benefits.
摘要:
An on-machine-seamable papermaker's fabric, which may be produced by modified endless weaving, includes machine-direction (MD) and cross-machine-direction (CD) yarns. When so produced, the MD yarns weave continuously back and forth between the two widthwise edges of the fabric, each time forming a seaming loop at one of the two widthwise edges. Interwoven with at least one of the two sides, top and bottom, of the seaming loops at one or both widthwise edges are at least two additional CD yarns. The additional CD yarns interweave with the top and/or bottom of the seaming loops in a leno weave, which keeps the seaming loops in a common position vertically relative to the plane of the papermakers fabric, locks the seaming loops into a desired position and orientation with their planes perpendicular to that of the papermaker's fabric.
