Abstract
Novel textile finishing compositions for finishing textile articles are provided via the present invention. The textile finishing compositions disclosed herein comprise a cross-linking agent and a catalytic amount of an esterification agent. The cross-linking agents employed herein are selected from a number of phosphorous containing materials derived from maleic acid. Also provided via the present invention are methods for applying the aforementioned finishing compositions to textile articles.
Claims10
A textile finishing composition comprising an aqueous composition having a) at least one cross-linking agent and b) a catalytic amount of an esterification catalyst, the cross-linking agent comprising at least one cross-linking adjunct selected from the group having formula
- wherein R is independently H, OH, OM, or a unit having the formula
- and mixtures thereof;
- X is H, OH, or OSO3M, M is H, or a salt forming cation, and mixtures thereof;
- the indices x, y, and z are each independently from 0 to about 7;
- x+y+z is less than or equal to 7, x+z is greater than or equal to 1, Q is H, OH, OM but not H when both x and z are greater than or equal to 1, and wherein the molecular weight of the cross-linking agent is from about 110 to about 700;
- wherein the finish further comprises an additional cross-linking adjunct selected from the group consisting of butane tetracarboxylic acid, oxy-disuccinate, imino-disuccinate, thiodisuccinate, tricarbalic acid, citric acid, 1,2,3,4,5,6-cyclohexanehexacarboxylic acid, 1,2,3,4-cyclobutanetetracarboxylic acid and mellitic acid.
A process for finishing a textile article, the process comprising the steps of:
- a) treating a non-finished textile component in an aqueous finishing bath containing a cross-linking composition, the cross-linking composition comprising an aqueous composition having i) at least one cross-linking agent and ii) a catalytic amount of an esterification catalyst, the cross-linking agent comprising at least one cross-linking adjunct selected from the group having the formula
- wherein R is independently H, OH, OM, or a unit having the formula
- and mixtures thereof;
- X is H, OH, or OSO3M, M is H, or a salt forming cation, and mixtures thereof;
- the indices x, y, and z are each independently from 0 to about 7;
- x+y+z is less than or equal to 7, x+z is greater than or equal to 1, Q is H, OH, OM but not H when both x and z are greater than or equal to 1, and wherein the molecular weight of the cross-linking agent is from about 110 to about 700,
- wherein the aqueous finishing bath further comprises 1,2,3,4-butanetetracarboxylic acid (BTCA) wherein the BTCA accounts for from about 0.1 to about 75% of the total cross-linking agent in the aqueous finishing bath;
- and
- b) curing the treated textile to form a finished textile.
