Abstract

Fibrous cellulosic material is modified by treating an aqueous suspension of the material, in which the dispersed fibres carry an electro-negative surface charge with (a) a reactive cationic coupling agent and (b) an aqueous dispersion of a dialdehyde-polysaccharide fibre-bonding agent. The reactive cationic coupling agent is a coupling agent that is attracted and adheres strongly to the anionic cellulose fibres, and contains both a nitrogen-containing group and a group that will react with the carbonyl groups of the fibre-bonding agent. Examples are: a dicyandimide-formaldehyde reaction product, tetramethylolacetylendiurea, polyethylenimine, 2,4,6-triethylenamine-1,3,5-triazine, diethylenhexamethylendiurea 1 - hydroxyethyl- 2 - heptadecenylglyoxalidine, dicyanoguanidine, guanylurea, acetoguanamine, acetaldehyde cyanohydrin, N-methyltaurine, cetylpyridinium chloride, polyvinylpyrrolidene, an alkyltrimethylammonium chloride, a dialkyldimethylammonium chloride, a quaternary ammonium salt of a dialkyl long chain fatty acid, a polyoxyethylated alkylamine, 4,4-di-(ethylenurea)-diphenylmethane, ethylenurea and trimethylolnitromethane. The fibre-bonding agent is a polysaccharide. e.g. starch cellulose, dextran, algin or insulin that has been oxidized by periodate. The suspensions so treated can be used to make paper of improved dry and wet strengths and dielectric strength. The pH of the suspension may be adjusted with alum, or with sulphuric, hydrochloric or formic acid The pulp may also be treated with a phenolformaldehyde resin; a fortified rosin size containing a maleic anhydride adduct of rosin; polyvinyl acetate, rosin amides, urea-formaldehyde resins, melamine-formaldehyde resins; carboxymethylcellulose; an emulsion of butadiene-styrene copolymer, organic polysulphide, butyl rubber or polyvinyl acetal and polyvinyl alcohol or polyacrylic acidALSO:Fibrous cellulosic material is modified by treating an aqueous suspension of the material, in which the dispersed fibres carry an electronegative surface charge with (a) a reactive cationic coupling agent and (b) an aqueous dispersion of a dialdehyde-polysacharide fibre-bonding agent.
