Abstract

A non-woven fabric comprises an atactic (i.e. non-crystalline) polypropylene binding agent. The fabric comprises either a bonded mat or web of fibres or two sets of parallel yarns, one set at right angles to the other, bonded together. Specified fibres are cotton, rayon, cellulose acetate and triacetate, nylon, acrylic, polyester, glass, vinyl polymer and copolymer fibres or mixtures thereof and also cellulose fibres used for making paper, wood pulp fibres and fibres derived from waste paper. The binder may be applied by (a) passing the fibrous web through a liquid binder bath and then through squeeze rolls to remove excess binder; (b) passing the web through a series of rolls which pick up the binder and transfer it to the web; (c) spraying the binder on to the web surface; or (d) applying the binder in a uniform pattern, resulting in definite bonded and unbonded portions. The finished fabric preferably contains from 30% to 280% of atactic polypropylene, as based on the dry weight of the fibres. The binder is applied to the web in the form of an organic solvent solution or an aqueous emulsion. The initial pickup by the web of the solution or emulsion ranges from 4% to 500%, by weight, as based on the weight of the web. Specified solvents are aromatic hydrocarbons, such as toluene, xylene, decahydronaphthalene and tetrahydronaphthalene; aliphatic hydrocarbons containing from 5 to 11 carbon atoms, such as pentane, hexane, and nonane; chlorinated hydrocarbons, such as methylene chloride, carbon tetrachloride, trichloroethylene, perchloroethylene', and chlorinated aromatic hydrocarbons such as chlorobenzene. The resin solids content of the solution ranges from 1% to 50% by weight. An emulsion may be applied by adding an emulsifying agent to an organic solvent solution of atactic polypropylene, the solvent being any of those specified above, adding water with vigorous agitation and removing the solvent by distillation. A specified emulsifying agent is oleic acid and morpholine. The resin solids content of the emulsion ranges from 2% to 65% by weight. Defoamers, resins to impart wet strength and lubricants may be added to the binder. The impregnated web may be dried at a temperature between room temperature and 350 DEG F.
