A method for forming a fibrous web by wet-laying fibers on paper-making equipment, the web comprising staple length natural or synthetic fibers and wood cellulose paper-making fibers wherein a water furnish of the fibers is made up with an associative thickener in the absence of a conventional surfactant. A preferred associative thickener for use with hydrophobic fibers is a urethane block copolymer having a polyethylene glycol backbone, the associative thickener acting as both surfactant and thickener. With predominately cellulosic fibers, i.e. conventional wood cellulose fibers, or a mixture of conventional and contorted wood fibers, and synthetic cellulosic fibers, such as rayon, a hydroxyethyl cellulose having a long alkyl side chain is preferred. Excellent consistency of the water and fiber dispersion is obtained at relatively low viscosity with rapid drainage of water from the wire and uniform formation of the web.

Novel pulp, paper and paperboard manufacturing methods utilizng non polar organic solvents. These solvents can be introduced into the pressing operation of the pulp, paper, or paperboard making machine or can be substituted for water at any point after the formation stage. The result is a significant saving in dryer energy which can be translated to greater productivity in dryer-limited processes, accompanied by an improvement in tensile strength and other physical properties.
4 Viscous dispersion for forming wet-laid, non-woven fabrics US551399 1975-02-20 US4049491A 1977-09-20 Ralph E. Brandon; Charles J. Davis; Michael Ring; Roy S. Swenson
An improved process for forming a non-woven fabric by wet-laying, on paper making equipment, staple length, synthetic fibers having a length to diameter ratio of about 400 to 3000, and an improved, non-woven fabric produced by the process. The process involves forming a stable, viscous, uniform, air-fiber-water dispersion by: adding the fibers to a high-shear agitated mixture of water and a dispersant to separate the fibers and to completely and uniformly distribute the individual fibers throughout the resulting, high-shear agitated, air, water and fiber mixture; and then, slowly adding a thixotropic thickener to the high-shear agitated mixture to form the viscous, air-fiber-water dispersion, having a nascent viscosity of about 10 to 125 cps., when measured at a shear rate of 30.5 sec..sup.-1, and in which the individual fibers are restrained from becoming entangled and from forming knits, bundles, and strings.

7 Method for preparing composite felt preforms EP87116336.6 1987-11-05 EP0275382A1 1988-07-27 Brun, Milivoj Konstantin; Morrison, William Arthur; Besio, Gregory John; McAlea, Kevin Patrick; Matsumoto, Dean Saburo; Vallance, Michael Alan

Composite felt preforms are prepared by dispersing a plurality of chopped fibers as a slurry in a viscous liquid such as glycerol under conditions of substantially uniform laminar flow, removing said liquid to produce a fiber mat and contacting said mat with a particulate matrix material. Illustrative matrix materials are ceramics, metals, thermoplastic resins and thermosetting resins. Depending on its particle size and other properties, the matrix material may be subsequently deposited on the already formed mat or may be codispersed with the fibers to form a mixed slurry which forms the mat.

A method for forming a non-woven fabric web by wet-laying fibers on paper-making equipment, the web comprising staple length natural or synthetic fibers and wood cellulose paper-making fibers wherein a water furnish of the fibers is made up with a nonionic associative thickener in the absence of a conventional surfactant. A preferred associative thickener for use with hydrophobic fibers is a nonionic urethane block copolymer having a polyethylene glycol backbone, the associative thickener acting as both surfactant and thickener. With predominately cellulosic fibers, i.e. conventional wood cellulose fibers, or a mixture of conventional and contorted wood fibers, and synthetic cellulosic fibers, such as rayon, a nonionic hydroxyethyl cellulose having a long alkyl side chain is preferred. Excellent consistency of the water fiber dispersion is obtained at relatively low viscosity with rapid drainage of water from the wire and uniform formation of the non-woven fabric.

11 Method for producing oriented fleeces or mats of short length fibers US389614 1982-06-18 US4505777A 1985-03-19 Heinz Richter
The distribution and orientation of the fibers in a short fiber fleece is improved by flowing the fiber suspension onto the surface of a rotating drum through a plurality of relatively narrow channels formed in a chute. The channels may be parallel partition walls extending in the flow direction or the channels may be formed by hoses or pipes placed one next to the other on the chute. The flow speed at the exit end of the chute may be increased by narrowing the exit end cross-sectional area.

1450831 Tufted water-laid non-woven fabric DEXTER CORP 14 March 1974 [15 March 1973] 11395/74 Heading D2B A tufted water-laid non-woven fabric has a planar body portion and a plurality of spaced fibre tufts integral therewith and extending therefrom in the form of weft-like fibre bundles, the tufts being composed of individual fibres secured to the body portion at only one end thereof. The fibres may be man made or synthetic polymeric fibres e.g. of nylon, polyester, or vinyl polymers or copolymers, rayon; optionally in combination with natural fibres such as kraft, manila, hemp or jute fibres. Inorganic fibres such as glass, quartz, ceramic, mineral wool, or asbestos fibres may also be used. The fibres may have a denier of from 1 to 15 d.p.f. and a length ranging from 1/16 inch to several inches. The fabric may be formed from a suspension of the fibres in a medium preferably having a viscosity greater than 3 centipoises. The desired viscosity may be obtained by the use of viscosity regulants such as water-soluble acrylamides, polyethylene oxide, carboxymethyl cellulose, water-soluble polymeric electrolytes of methacrylic acid and copolymers thereof, degradable enzymes, mixtures of natural and synthetic gums and inorganic salts. The fabric may be formed with a non-woven or woven scrim or gauze embedded within it, the scrim or gauze acting both as the forming element and as a reinforcing element. The fabric may be used for making wash cloths, wiping cloths, towels, wipes, sanitary napkins, blankets, dish cloths, bandages, dressings, wall coverings, insulating materials or filters inter alia.
