Abstract
A silicone composition is provided which comprises at least one polysiloxane or siloxane oligomer functionalized with at least one amino group and at least three functional groups capable of cross-linking wherein the polysiloxane or siloxane oligomer imparts flame retardancy on a cellulose-containing substrate. Further embodiments of the present invention include a method for making and a cellulose-substrate comprising the aforementioned silicone composition.
Claims22
A textile treating composition, comprising:
- aluminum lactate;

- wherein the subscripts a, b, c, d, e, f and g are zero or a positive integer, subject to the limitations that each of the subscripts b, d and f are positive integers, and the sum of the subscripts b, d and f is at least 4,
- and wherein
- M has the formula:
- R13SiO1/2,
- M′ has the formula:
- (X)hR23-hSiO1/2,

- each R1,R2, R3, R4, R5 is independently at each occurrence one of the at least three cross-linking groups, hydrogen, C1-30 alkyl, C1-22 alkoxy, C2-22 alkenyl, C5-14 aryl, C6-22 alkyl-substituted aryl, C6-22 aralkyl, or C1-22 polyether;
- and each X is independently at each occurrence one of the at least one amino group or the at least three cross-linking groups,
- wherein the textile treating composition imparts flame retardancy to a textile when adhered to the textile, and
- wherein the branched polysiloxane or the branched siloxane oligomer is present relative to the aluminum lactate in a weight ratio of 5:3.7.
