Abstract

Now-woven fabrics are bonded by treatment both with an aqueous solution of a polyamine, polyalcohol or polyphenol and also with a solution (the solvent being one which is substantially insoluble in water) of an acid chloride which contains two acid chloride groups in the molecule; the sequence of the treatments with the two solutions is immaterial. Examples of the polyamines, polyalcohols and polyphenols are hexamethylene-diamine, tetramethylene-triamine, phenylene-diamine, ethylene glycol, glycerol, butanediol, butenediol, cyclohexanediol, neopentyl glycol and resorcinol. The acid chlorides used to react with these components are aromatic or aliphatic acid dichlorides such as the dichlorides of oxalic, malonic, succinic, glutaric, adipic, sebacic, maleic and terephthalic acids, or itaconic acid trichloride. Suitable solvents for these acid chlorides include hexane, heptane, cyclohexane, benzene, toluene, chloroform and trichloroethylene. Fibres which may be bonded by the above treatment include nylon 6, nylon 66, linear polyesters, acrylic fibres, natural fibres such as cotton and wool, and inorganic fibres such as glass or mineral wool. The preferred range of concentrations of the solutions with which the fabric is impregnated is from 1 to 10% by weight and impregnation may be effected by repeated dipping in a bath of the solution. Excess liquid may be removed by passage between squeeze rollers. Temperatures above atmospheric may be used if desired. Hydrogen chloride may be liberated by reaction between the two components and suitable alkalis may be included in the aqueous solution to prevent its escape. In Example 1 the aqueous solution contains 0.05% by weight of the adduct of 6 moles of ethylene oxide and 1 mole of p-isooctylphenol; in Example 8 the solution of acid chloride contains 10% by weight of p-hydroxybenzoic acid 2 ethylhexanol ester as plasticizer.
