Abstract: The felting material, consisting of natural and/or synthetic fibres, is subjected to a point compression by steel lips in a V formation to allow hot fluid polymerisates to be passed into the material. This is allowed to reassert itself for coling to stabilise the polymerisate layer inside. Strength and stability is given to the felt, esp. for carpeting applications, without wastage.

Abstract: Bonded fibre material (I) comprises (A) 5-50 wt. % aq. dispersion (binder) with disperse phase contg. (A1) 30-90 wt. % conjugated diene (w.r.t. dry phase), (A2) 0-50 wt. % copolymerisable alpha, beta-unsatd. mono- or di-carboxylic acid or amide, ester or nitrile, vinyl ester and/or cinyl-aromatic monomer and (A3) 3-20 wt. % olefinic comonomer with OH gp.(s), (B) 50-95 wt. % normal non-bonded fibre fabric with softening pt. above 320 deg. C and opt. (C) other resins, waxes or bitumen; (I) is obtd. by treating material (B) with a liq. contg. (A) at pH below 8, drying at 170 deg. C or above and opt. applying (C). Pref. disperse phase in (A) is a copolymer with Tg below 0 deg. C, derived from 40-85 wt. % (A1) (pref. butadiene, isoprene and/or chloroisoprene), 0-50 wt. % mono- or di-acid or derivs. as above and/or styrene (A2) (pref. (meth)acrylic acid or derivs. thereof and/or styrene) and 5-15 wt. % (A3) hydroxyethyl acrylate (HEA), hydroxypropyl acrylate (HPA) and/or butanediol monoacrylate (HBA); impregnating liq. has pH below 5, with pref. solids content 10-30 wt. %, and drying temp. is at least 180 deg. C. USE/ADVANTAGE - (I) is useful for the prodn. of roofing strip (claimed). The invention provides bonded fibre material with thermal stability equiv. to that of materials based on dispersions contg. N-methylol gps., but which does not liberate formaldehyde during drying. (7pp Dwg.No.0/0)

Abstract: (In)organic fibre mat is bonded with a cured resin mixt., consisting of (A) 5-80 (wt.)% water-soluble prod. with a carbonyl no. of 0-200 prepd. by alkaline condensation from 0.1-0.4 mole condensable (cyclo)aliphatic ketone and 1 mole HCHO and (B) 20-95% water-soluble aminoplastics and/or phenolic resin. (A) has a carbonyl no. of 40-180 and is prepd. using a ketone:HCHO molar ratio of 0.2-0.25:1. (B) is a water-soluble urea or melamine resin or 4,5-dihydroxyimidazolidin-2-one or its unetherified, partly etherified or completely etherified condensation prods. with HCHO, glyoxal and/or glutarodialdehyde, esp. 1,3-dimethylol-4,5- dihydroxyimidazolidin -2-one. The fibre mat is impregnated with an aq. soln. of the binder, dried and cured.

Abstract: Webs composed of inorganic or organic fiber material are bonded with a cured resin mixture consisting essentially of (A) from 5 to 80% by weight of a water-soluble condensation product of carbonyl number 0-200 which has been prepared by alkaline condensation from 0.1 to 0.4 mole of an aliphatic or cycloaliphatic condensable ketone and 1 mole of formaldehyde, and (B) from 20 to 95% by weight of a water-soluble amino and/or phenolic resin.
