Title: New polyglycol ether derivatives and process for their manufacture and process for imparting a soft feel to textile fibres
IPC: D06M13/405
Filed: 1956-07-13
Abstract: The invention comprises polyglycol derivatives of the formula <FORM:0833748/IV (b)/1> where R1 is an aliphatic hydrocarbon radical such that the acyl radicals -OC-R, together contain at least 20 carbon atoms, k is an integer, and m and n are 1-3.  These are made by reacting ethylene oxide with the corresponding acylated di- and poly-amines, preferably to introduce 8-30 or more oxyethylene units per mol. of acylamine.  The starting materials are obtained by acylating the di- or poly-amine with a fatty acid (or chloride or anhydride thereof), be ethylene diamine, trimethylene diamine, triethylene tetramine, tetraethylene pentamine or a product obtained by heating an ethylene dihalide or glycerol dichlorhydrin with ammonia or an amine such as ethanolamine.  In examples ethylene oxide is reacted with the products from (1) stearic acid and diethylene triamine, (2) stearic acid, diethylene triamine and acetic anhydride, and (3) stearic acid and propylene diamine.  The Specification also refers to ethylene oxide condensation products of polyamines H2N-Alkylene-[-NH-Alkylene-]m-1-NH2 acylated with at least 2 residues of fatty acids containing together at least 20 carbon atoms, and salts of such products.  An example is given of the preparation of distearoyl-diethylenetriamine, condensation with ethylene oxide and conversion into the acetate salt.ALSO:A soft feel is imparted to textile fibres (especially cellulose) by treating them with polyglycol derivatives of acylated amines of the formula <FORM:0833748/IV(c)/1> where m is 1-3, such that there are at least 2 acyl radicals present derived from fatty acids containing together at least 20 carbon atoms and each carbon atom bound to an oxygen atom is bound to a single oxygen atom; salts of the derivatives may be used. Treatment may be in an anti-crease bath.  In examples defatted viscose yarn is treated with the polyglycol derivatives of di- and tri-stearoyl-diethylene triamine, the former being used as its acetate salt.ALSO:The invention comprises polyglycol derivatives of the formula <FORM:0833748/IV (a)/1> where R1 is an aliphatic hydrocarbon radical such that the acyl radicals -OC-R1 together contain at least 20 carbon atoms, k is an integer, and m and n are 1-3.  The compounds are made by acylating a di- or poly-amine with a fatty acid (or chloride or anhydride thereof) and reacting the product with ethylene oxide.  The amine can be ethylene diamine, trimethylene diamine, triethylene tetramine, tetraethylene pentamine or a product obtained by heating an ethylene dihalide or glycerol dichlorohydrin with ammonia or an amine such as ethanolamine. The fatty acid can be lauric, myristic, palmitic, stearic, arachic, behenic, oleic or linoleic.  In examples ethylene oxide is reacted with the products from (1) stearic acid and diethylene triamine, (2) stearic acid, diethylene triamine and acetic anhydride, and (3) stearic acid and propylene diamine.  The Specification also refers to ethylene oxide condensation products of polyamines H2N-Alkylene-NH-Alkylene-m-1RH2 acylated with at least 2 residues of fatty acids containing together at least 20 carbon atoms, and salts of such products.
