摘要： A selfbonded nonwoven fabric comprising at least 70 weight percent of sheath/core heterofilaments having a core of isotactic polypropylene in which the sheaths are high density polyethylene in an amount of 5 to 30 weight percent of the heterofilaments, and method of preparation. The fabrics have outstanding strength, fatigue resistance, and tear resistance and are eminently suitable for civil engineering applications such as unpaved road underlay material.

摘要： This invention resides in a flame-resistant nonwoven fabric having an upper and a lower surface and comprising dyeable, flame-resistant fibers and base fibers. In one embodiment the upper surface is substantially, completely comprised of polyvinyl chloride fibers and the lower surface is a blend of adhering base fibers and polyvinyl chloride fibers. The fabric is formed by needling base fibers together to form a batt, needling polyvinyl chloride fibers and the batt together, and heating the lower surface of the fabric to adhere the polyvinyl chloride and base fibers together.

摘要： A process and device useful therein for hydraulically entangling the fibers in a fiber batt to form a fiber-entangled base sheet for a non-woven fabric, and a uniformly and lightly fiber-entangled, base sheet formed by the process. The process includes applying at least one liquid curtain against the fiber batt while it is supported on a moving, apertured backing screen. The liquid curtain is uniform in width throughout its length and substantially non-diverging as it is delivered from a source of liquid under a pressure sufficient to effect entanglement of the fibers in the batt. Preferably, the pressure is at least about 200 p.s.i.g., and the maximum divergence of the curtain is about 4 degrees. The device for applying the liquid curtain includes first and second members and means for securing the members together to form a chamber therebetween in which the liquid is contained and to form a slot in communication from the chamber to the exterior of the device. The slot has a substantially uniform width along its length and preferably also a uniform depth. The securing means are adjustable, so that the width of the slot can be varied, but, once the members are secured together, the width of the slot remains constant as the curtain is delivered from the chamber, through the slot, and against the fiber batt. The uniformly and lightly fiber-entangled, base sheet is non-apertured and non-streaked and has an entanglement frequency of less than about 20, an entanglement completeness of less than about 0.5 and an internal bond value of less than about 0.1.

摘要： A method of treating a layer of fibers to form a fibrous web having various areas of fiber concentration and opacity. The fiber layer is supported on an impermeable member and moving forces are applied to the supported layer. The forces move the fibers into areas of varying opacity and fiber concentration while maintaining substantially uniform density throughout these areas.

摘要： Lightweight, nonpatterned, nonwoven fabrics suitable for use as wearing apparel are produced by treating fibrous sheet materials with fine, essentially columnar streams of liquid jetted from orifices under high pressure. A layer of fibrous material is supported on a nonpatterning surface and traversed with the streams to entangle the fibers in a manner which imparts strength and stability without the need for binder. A smooth fabric surface is provided by use of broken streams or by rapid oscillation of the streams.

摘要： Systems and methods for reinforcing structures with composite reinforcement systems are disclosed herein. According to aspects of the present disclosure, a carrier of a composite reinforcement system for repairing and/or reinforcing a physical structure is disclosed. The carrier includes a plurality of carbon fibers. Each carbon fiber has a longitudinal axis and a length extending in a generally 0 degree direction. The carrier further includes at least one fiberglass fiber having a longitudinal axis and a length extending in a generally 90 degree direction across the plurality of carbon fibers. The plurality of carbon fibers constitute at least about 70 wt % of the carrier and the at least one fiberglass fiber constitutes at most about 30 wt % of the carrier.

摘要： A continuous filament spun-laid web includes a plurality of polymer fibers within the web, the web having a first thickness and the web being free of any thermal or mechanical bonding treatment. Activation of the web results in at least one of an increase from the first thickness prior to activation to a second thickness post activation in which the second thickness is at least about two times greater than the first thickness, a decrease in density of the web post activation in relation to a density of the web prior to activation, the web being configured to withstand an elastic elongation from about 10% to about 350% in at least one of a machine direction (MD) of the web and a cross-direction (CD) of the web, and the web having a tensile strength from about 50 gram-force/cm2 to about 5000 gram-force/cm2.
