The present invention provides a multilayer multiaxial woven fabric for a papermachine having a reduced interference pattern and accordingly improved dewatering uniformity. The present invention also provides a method of forming such multilayer multiaxial fabric.

Multiaxial fabrics

The present invention provides a multilayer multiaxial fabric for a paper machine having a reduced interference pattern and accordingly improved dewatering uniformity. The present invention also provides a method of forming such a multilayer multiaxial fabric.

A seamless, woven, flexible fluid containment vessel or vessels for transporting and containing a large volume of fluid, particularly fresh water, having beam stabilizers, beam separators, reinforcing, and the method of making the same.

Flexible fluid containment vessel

A method whereby a water permeable press fabric is given greater dewatering and drainage capacity by providing voids which are reservoirs of minimum pressure available to accept water.

Method for increasing press fabric void volume by laser etching

A press fabric for the press section of a paper machine has a base fabric which includes a nonwoven mesh fabric. The base fabric, or a layer thereof, is assembled in integral form using a strip or strips of the nonwoven mesh fabric. The assembly may be effected by spirally winding the nonwoven mesh fabric in a plurality of non-overlapping turns, by abutting each turn of the nonwoven mesh fabric against that previously wound, and by joining each turn of the nonwoven mesh fabric to that previously wound to form an endless loop. Alternatively, a plurality of endless loops of equivalent length are formed from separate strips of nonwoven mesh fabric, and arranged in a side-by-side abutting relationship. The endless loops are then joined, one to the next, to provide a base fabric, or component thereof, in the form of an endless loop.

Method for joining nonwoven mesh products

An industrial process fabric is embossed in a device, such as a continuously operating two-roll calender having a preselected embossing pattern. The roll(s) of the calender may alternatively themselves be engraved or etched to provide the embossing. Embossing takes place with controlled temperature, pressure, speed and gap (between the rolls) settings. The fabric may be a forming, press, dryer or TAD fabric used in paper and pulp production, pulp forming fabric or an engineered fabric used to produce nonwoven textile products by meltblowing, spunbonding, hydroentangling or air laid needle punching.

Embossed fabrics and method of making the same

A method for manufacturing a papermaker's fabric by spirally winding a woven fabric strip, narrower than the intended width of the fabric, and the papermaker's fabric manufactured in accordance with the method, are disclosed. The fabric strip includes lengthwise and crosswise yarns, and has a lateral fringe along at least one lateral edge thereof, the lateral fringe being unbound ends of the crosswise yarns extending beyond the lateral edge. During the spiral winding of the fringed strip, the lateral fringe of a turn overlies or underlies an adjacent turn of the strip. The lateral edges of adjacent turns abut against one another. The spirally continuous seam so obtained is closed by ultrasonically welding or bonding the overlying or underlying lateral fringe to the fabric strip in an adjacent turn.

Ultrasonic seaming of abutting strips for paper machine clothing

Insulating material comprising continuous filaments of a synthetic material characterized in that the filaments have a mean diameter of from 4 to 20 microns and in that the filaments have been separated by a stretching and subsequent relaxation of a crimped tow of said filaments.

Thermally insulating continuous filaments materials

This invention relates to synthetic fiber thermal insulator material in the form of a cohesive fiber structure, which structure comprises an assemblage of:

Synthetic down

A thermal insulator is disclosed which comprises fibrillated staple fibers exemplified by fibrillated fibers of poly (p-phenylene terephthalamide). The fibers are fibrillated on a carding machine equipped with metallic clothing.

A synthetic replacement for down is described which comprises a blend of

The disclosure is of a penetration resistant panel which comprises plied layers of interwoven textile yarns of poly(p-phenylene terephthalamide) backed with plied layers of woven or non-woven fibers of Nylon 6,6. The panels of the invention are useful as ballistic-protective armor and are inherently lower in cost than similarly-effective panels comprised solely of poly(p-phenylene terephthalamide).

Penetration resistant textile panels with plies of nylon and plies of

A composite waterproof fabric for tent walls and the like which is suitable for use under severe service conditions, and which is opaque, of light weight and flame or fire resistant. The fabric comprises at least three plies, namely outer and inner woven, flame resistant plies and a middle ply of polytetrafluoroethylene which is hydrophobic, microporous and moisture vapor permeable. Tensile strength and tear resistance are imparted to the composite fabric largely by the inner ply, and abrasion protection is imparted by the outer ply. A light weight fabric of this construction is opaque, color adaptable and flexible at very low ambient temperatures.
