摘要： A process for producing nonwoven materials is provided. The process includes: providing a three-phase (gas-liquid-solid) suspension, providing a first moving carrier sieve, applying the three-phase suspension onto the first moving carrier sieve to produce a fibrous web, removing aqueous residue of the three-phase suspension through the first carrier sieve, recycling the aqueous residue, pre-integrating the fibrous web by flushing the web with water and collecting flushed water, transferring the pre-integrated fibrous web from the first moving carrier sieve to a second moving carrier sieve, and hydroentangling the fibrous web. The three-phase suspension contains natural and/or manmade fibres, a surfactant, and air.

摘要： A method for hydroforming a composite precursor material includes forming a composite precursor material comprising an original spun bonded nonwoven web and a polymer film layer. The method also includes applying a plurality of pressurized liquid jets onto an outer surface of the original spun bonded nonwoven web while the composite precursor material passes over a forming structure to push and reorient a plurality of spun bonded fibers from a closely packed substantially horizontal orientation to a more loosely packed orientation with greater vertical spacing between the fibers to produce a hydroformed composite material comprising an expanded spun bonded nonwoven layer having a loft of at least about 1.3 times greater than the original loft of the original spun bonded nonwoven web, and an air permeability of at least about 1.2 times greater than an original air permeability of the original unexpanded spun bonded nonwoven web.

摘要： A resilient coform nonwoven web that contains a matrix of meltblown fibers and an absorbent material is provided. The meltblown fibers may constitute from 45 wt % to about 99 wt % of the web and the absorbent material may constitute from about 1 wt % to about 55 wt % of the web. The meltblown fibers may be formed from a thermoplastic composition that contains at least one propylene/α-olefin copolymer having a propylene content of from about 60 mole % to about 99.5 mole % and an α-olefin content of from about 0.5 mole % to about 40 mole %. The copolymer may have a density of from about 0.86 to about 0.90 grams per cubic centimeter and the thermoplastic composition may have a melt flow rate of from about 200 to about 6000 grams per 10 minutes, determined at 230° C. in accordance with ASTM Test Method D1238-E. The coform web may be imparted with a three-dimensional texture by, for example, using a three-dimensional forming surface. As one example, the resilient coform web is suitable for use as a component in the absorbent core of a personal care absorbent product.

摘要： A method of manufacturing a fibrous structure is particularly, though not exclusively, applicable to the manufacture of friction products such as preform discs. The method comprises mounting a former on a shaft. First feeds of fibrous material are spaced along the shaft and applied to the former in a direction tangential to the shaft as the shaft is rotated. A second feed is also applied to the former in a direction substantially parallel to the longitudinal axis of the shaft. The fibrous materials in the feeds overlie as the shaft rotates and the thickness of the material applied to the former increases to form the fibrous structure. Lengths of the first and/or second feeds are then inserted into the fibrous structure body in a radial direction with respect to the shaft as the shaft is rotated to interconnect the overlying layers and hold the structure together.
