Abstract:
A soft, durable, nonwoven fabric formed of hydroentangled synthetic polymer fibers in sheet form. The polymer fiber is surface embossed on at least one major surface with a predetermined pattern to provide a fiber sheet having enhanced dimensional stability. The fiber sheet is surface napped to soften the surface and disturb and make indistinct the surface embossed pattern. The pattern may preferably be a twill pattern, and the napping process is preferably a wire-napping process. The fabric can be constructed into blankets and numerous apparel items.
Abstract:
This invention provides an organ positioning device and method that employs suction to hold organ tissue to the device. The device allows the organ, for example, heart to be positioned in a desired orientation but otherwise allowing movement of the heart as the heart beats. The device is designed to be relatively atraumatic to heart tissue. Generally, the device comprises a resiliently flexible suction head having a plurality of legs that flex to conform to the surface of the heart. The suction head has vacuum passageways in fluid communication with the legs to apply suction between the legs and the surface of the heart.
Abstract:
Composite structures and methods are taught relating to temperature stabilizing saddle pads, horse blankets, saddle girths, saddle seat cushions, and saddles for protection and increased performance of horses and/or riders, among other similar products. The invention provides for products that stabilize the temperature of the horse and/or the rider by absorbing heat generated by the body of the horse and/or rider when the temperature exceeds a preset temperature appropriate for the product. In this process heat energy is absorbed through phase change, resulting in a constant temperature as long as there is material that has not changed phase.
Abstract:
The present invention is directed a nonwoven fabric which is imparted with a three-dimensional image or pattern, and apertures essentially devoid of fiber, during the fabrication stage. The nonwoven fabric exhibits a fibrous extension out of the plane of the material, while apertures are present that have a pronounced uniformity and a significant reduction in fibrous occlusion.
Abstract:
A method and plant for producing an air-laid non-woven web of cellulose fibers or of cellulose fibers mixed with synthetic fibers that includes at least one air-laying section for depositing fiber fluff into a layer upon a forming wire, an overlying second wire for transferring the layer of fluff to a third wire having a mesh count small enough for preventing the fibers from penetrating into the wire, and at least one nozzle for directing a water jet towards the fluff on the third wire, thereby hydroentangling the fluff into a coherent web. By the method and plant according to the invention, it is possible to produce hydroentangled fiber webs which are less expensive and have better absorption properties than hitherto known. The webs can be produced with weights between about 20 and 2000 g/m2.

Abstract:
The present invention is directed to a method of forming a nonwoven fabric, which exhibits a pronounced durable three-dimensional image, permitting use of the fabric in floor underlayment of laminate floor systems so as to reduce acoustic feedback under normal use (walking) due to sound absorption and leveling of the floating laminate floor system applications. In particular, the present invention contemplates that a fabric is formed from a precursor web comprising at least one support layer or scrim, whereby when subjected to hydroentanglement on a moveable imaging surface of a three-dimensional image transfer device, an enhanced product is achieved. By formation in this fashion, hydroentanglement of the precursor web results in a more pronounced three-dimensional image, an image that is durable to abrasion and distortion.
Abstract:
The present invention is directed to a method of forming a nonwoven fabric, which exhibits a pronounced three-dimensional image that is durable to both converting and end-use application. In particular, the present invention contemplates that a fabric is formed from a precursor web comprising at least one support layer or scrim, which when subjected to hydroentanglement on a moveable imaging surface of a three-dimensional image transfer device, an enhanced product is achieved. By formation in this fashion, hydroentanglement of the precursor web results in a more pronounced three-dimensional image; an image that is durable to abrasion and distortion due to elongation.
Abstract:
Disclosed is a laminate having flame and chemical resistance, which may be used to form protective fabrics. The laminate contains a first layer of a spunlace fabric having a fire retardant additive applied thereto; and a second layer of a polymeric film.
Abstract:
Colored patterning of a web-shaped nonwoven or a composite made of a nonwoven and a fabric or knit is achieved by water jet needling. The nonwoven provided as the upper layer of two layers is provided with one or more colors or is colored or printed itself and is placed on a second nonwoven or a woven or one that has a different color. Then both layers are subjected to the water jets that displace the fibers, with the colored fibers in the first layer being displaced into the second layer to produce a pattern on the underside of the second layer. It is also possible, instead of colored fibers in the nonwoven of the upper layer, to move them when they are not colored into a second layer that can have any color.
Abstract:
A bulky fibrous fabric is provided, made by a process comprising obtaining an unbonded, consolidated batt of fibers wherein each fiber has a ribbon-shaped cross-section, and needling said batt to obtain the bulky fibrous fabric. The fabric has a surface area of at least 2 m2/g and a thickness/basis weight ratio of at least 0.005 mm/g/m2 (7 mil/oz/yd2) The fabric has utility particularly as a dry wipe for cleaning and dusting.
