Title: Improvements in the fulling of wool
IPC: C07C279/26
Filed: 1965-02-11
Abstract: Diphenolic acid compounds suitable for use in the fulling of wool are produced by esterifying or etherifying at least one of the hydroxyl groups of diphenolic acid <FORM:1113791/C3/1> by esterifying the carboxyl group of diphenolic acid or such an ester or ether thereof with a monohydric or polyhydric alcohol or reducing the carboxyl group to an aldehyde group or amidating it by reaction with a primary, secondary or tertiary amine, or by reacting diphenolic acid or such a derivative thereof with formaldehyde.  Suitable compounds which may be reacted with diphenolic acid to produce these compounds are ethylene chlorohydrin, dichlorobutane, dichloroethyl ether, a -dichlorohydrin, oleic acid chloride, acetic anhydride, maleic, fumaric, diglycolic, adipic, sebacic, succinic, oleic, azelaic, lauric, or capric acid, glutaric anhydride, maleic anhydride, glycerol, polyglycerol, pentaerythritol, polypentaerythritol, sorbitol, trimethylol ethane, trimethylol propane, ethylene glycol, propylene glycol, ethylene oxide addition polymers of polypropylene glycol, aliphatic ethylene oxide addition products, octyl alcohol, oleyl alcohol, triethanolamine, tripropanolamine, ethylene diamine, hexamethylene diamine, ethylene triamine, triethylene tetramine, tetraethylene pentamine, hydroxyethyl ethylene diamine, aliphatic amines containing more than 7 carbon atoms, dicyandiamide, mono- or di-ethanolamine or trimethylol aminomethane.  The fulling composition may also comprise an organic solvent, e.g. propyl alcohol, ethylene glycol, propylene glycol, acetone, ethyl ketone, cyclohexanone, ethylene glycol monoethyl ether, ethylene glycol monoethyl ester or diethylene glycol monomethyl ether, an emulsifying agent, e.g. polyoxyethylene condensates of an alkylamide, polyoxyethylene alkyl phenol ether, co-condensates of polyoxyethylene and a polyoxypropylene, a polyoxyethylene alkyl ester or alkyl ether or phosphate thereof or an alkyl allyl sulphonate, an amine resin, acrylamine resin, acryl ester resin or vinyl resin.ALSO:Diphenolic acid compounds suitable for use in the fulling of wool are produced by esterifying or etherifying at least one of the hydroxyl groups of diphenolic acid, by esterifying the carboxyl group of diphenolic acid or such an ester or ether thereof with a monohydric or polyhydric alcohol or reducing the carboxyl group to an aldehyde group or amidating it by reaction with a primary, secondary or tertiary amine, or by reacting diphenolic acid or such a derivative thereof with formaldehyde. Suitable compounds which may be reacted with diphenolic acid to produce these compounds are ethylene chlorohydrin, dichlorobutane, dichloroethyl ether, a -dichlorohydrin, oleic acid chloride, acetic anhydride, maleic, fumaric, diglycolic, adipic, sebacic, succinic, oleic, azelaic, lauric or capric acid, glutaric anhydride, maleic anhydride, glycerol, polyglycerol, pentaerythritol, polypentaerythritol, sorbitol, trimethylol ethane, trimethylol propane, ethylene glycol, propylene glycol, ethylene oxide addition polymers of polypropylene glycol, aliphatic ethylene oxide addition products, octyl alcohol, oleyl alcohol, triethanolamine, tripropanolamine, ethylene diamine, hexamethylene diamine, ethylene triamine, triethylene tetramine, tetraethylene pentamine, hydroxyethyl ethylene diamine, aliphatic amines containing more than 7 carbon atoms, dicyandiamide, mono- or di-ethanolamine and trimethylol aminomethane.ALSO:Wool or wool mixtures with synthetic fibres or fabrics or needled felts produced there from are fulled by treating them with a fulling composition containing a diphenolic acid compound which is diphenolic acid itself, diphenolic acid in which at least one of the hydroyl groups is esterified, diphenolic acid in which at least one of the hydroxyl groups is esterified, a diphenolic acid compound in which the carboxyl group of any of these compounds is esterified with a monohydric or polyhydric alcohol, reduced to an aldehyde group or amidated by reaction with a primary, secondary or tertiary amine or a condensation product of any of these compounds with formaldehyde.  Compounds which may be reacted with diphenolic acid to produce compounds for use in fulling compositions are ethylene chlorohydrin, dichlorobutane, dichloroethyl ether, a -dichlorohydrin, oleic acid chloride, acetic anhydric, maleic, fumaric diglycolic, adipic, sebacic, succinic, oleic, azelaic, lauric or capric acid, glutaric anhydride, maleic anhydride, glycerol, polyglycerol, pentaerythritol, polypentaerythritol, sorbitol, trimethylol ethane, trimethylol propane, ethylene glycol, propylene glycol, ethylene oxide addition polymers of polypropylene glycol, aliphatic ethylene oxide addition products, octyl alcohol, oleyl alcohol, triethanolamine, tripropanolamine, ethylene diamine, hexamethylene diamine, ethylene triamine, triethylene tetramine, tetraethylene pentamine, hydroxyethyl ethylene diamine, aliphatic amines containing more than 7 carbon atoms, dicyandiamide, mono- or diethanolamine, and trimethylol amino methane.  The fulling composition may comprise an organic solvent, e.g. propyl alcohol, ethylene glycol, propylene glycol, acetone, ethyl ketone, cyclohexanone, ethylene glycol monoethylether, ethylene glycol monoethylester or diethylene glycol monomethyl ether, an emulsifying agent, e.g. polyoxyethylene condensates of an alkylamide, polyoxyethylene alkyl phenol ether cocondensates of polyoxyethylene and a polyoxypropylene, a polyoxyethylene alkyl ester or alkyl ether or phosphate thereof or an alkyl allyl sulphonate.  The composition may also contain an amine resin, acrylamine resin, acryl ester resin or vinyl resin.
