Abstract
1527733 Non-woven fabric HOECHST AG 15 Sept 1975 [13 Sept 1974] 37861/75 Headings D1R and D2B A non-woven fabric is bonded with a polymer containing groups of formula In example 4 340g butyl acrylate, 60g acrylonitrile and 20g acrylamide are emulsion polymerised in the presence of 500 ml water, 25g sodium alkylsulphonate and 7.5g ammonium peroxidisulphate. To the polymer dispersion at pH 2.6 is added 20.8g N-methylol-formamide at 60‹C and the temperature maintained at 60‹C for 90 minutes to convert the acrylamide units to units of partial formula I. Alternatively, as in ex. 1-3, a copolymer is obtained from a monomer mixture containing 0.2 to 50% by weight of the monomer where R 1 and R 2 may each be independently hydrogen or methyl. The monomer mixture may also include 40 to 95% of acrylic and/or methacrylic esters having 1 to 8 carbons in the alcohol radical, e.g. butyl and isooctyl, 0.5 to 2% of acrylic and/or methacrylic acid, 0-6% of acrylamide and/or methacrylamide, 0-47% of other monomers having one olefinic double bond, e.g. acrylonitrile, styrene, crotonic or maleic acid or ester thereof, ethylene and propylene and 0-5% of butanediol, dimethacrylate, diallylphthalate, tetraallyloxethane or other polyolefinic monomer. Copolymerisation is carried out at 10 to 90‹C in an aqueous emulsion in the presence of specified peroxy catalysts, reducing agents and emulsifiers. The polymer is stable to storage. It may be cross linked at above 80‹C or above 50‹C in the presence of acid or alkaline catalysts. Polymers containing sufficient (meth)acrylic acid units are soluble in water. Fabric. Fibres or filaments of jute, cotton, linen, viscose or cuprammonium rayon, cellulose 2¢ or 3 acetate, wool, silk, glass, asbestos, polyester, polyamide, polyacrylonitrile, modacrylic, polyolefine, polyvinyl and/ or polyurethane may be formed into carded, wet laid, felted or spun laid fabrics and may be needled or stitch bonded. As 25-55% aqueous solution or emulsion of the copolymer binder is applied by spraying, padding, dipping or doctoring to give an uptake of 10 to 100% of solids based on the weight of the fibres. In Example 5 a carded polyester fleece was coated by spraying 15g/m
