Abstract

A system for controlling extraneous free flowing dyes or colorants in a liquid bath by using a dye scavenger member having a textile substrate or the like impregnated with a dye scavenging material such as N-trisubstituted ammonium 2 hydroxy 3 halopropryl compounds or salts of epoxy propyl ammonium compounds such as glycidyltrimethylammonium chloride. Such members, and the methods of making and using same are included.

Claims

1. A method of controlling undesirable random dye or colorant in a liquid bath containing sources of undesirable random dye or colorant and textile material of color other than the color of said undesirable dye or colorant, comprising placing in said bath a dye scavenger member comprising a cellulosic substrate material bearing a dye scavenger material, said dye scavenger material comprising a compound from the group consisting of:

a N-trisubstituted ammonium-2-hydroxy-3-halopropyl compound having the general formula ##STR3## or a salt of epoxy propyl ammonium having the general formula ##STR4## wherein X is a halogen radical, Y is chloride, bromide, sulfate or sulfonate, and the R'"'"'s are methyl, ethyl, butyl or benzyl groups or an hydroxyl substituted derivative thereof and then using said liquid bath for its intended purpose, wherein said undesirable random dye or colorant becomes associated with said dye scavenger member.

2. The method of claim 1, wherein said substrate is a cellulosic material.

3. The method of claim 2 wherein said dye scavenger material is glycidyltrimethylammonium chloride.

4. The method of claim 3 wherein said substrate is a non-woven textile material.

5. A method of preventing discoloration of textile materials in a liquid laundry bath, comprising:

providing a laundry bath with textile materials of different colors therein,

placing in said bath a dye scavenger member comprising a cellulosic substrate material bearing a dye scavenger material, said dye scavenger material comprising a compound from the group consisting of;

a N-trisubstituted ammonium-2-hydroxy-3-halopropyl compound having the general formula ##STR5## or a salt of epoxy propyl ammonium having the general formula ##STR6## wherein X is a halogen radical, Y is chloride, bromide, sulfate or sulfonate, and the R'"'"'s are methyl, ethyl, butyl or benzyl groups or an hydroxyl substituted derivative thereof,

leaving said dye scavenger member in said bath throughout an entire laundering procedure, whereby any random dyes or colorants which dissociate from said differently colored textile materials become associated with said dye scavenger member and do not discolor a textile material of a different color from said random dyes or colorants.

6. The method of claim 5, wherein the steps of claim 5 are repeated a plurality of times using the same dye scavenger member.

7. The method of claim 5 wherein said substrate is a cellulosic material.

8. The method of claim 5 wherein said substrate is a cotton fabric.

9. The method of claim 7 wherein said substrate is non-woven.

10. The method of claim 5 wherein said dye scavenger material is glycidyltrimethylammonium chloride.

11. A method of preventing discoloration, and promoting the color brightness of textile materials in an aqueous laundry bath, comprising:

providing an aqueous laundry bath with textile materials of different colors therein, at least one of said textile materials having a dye or colorant associated therewith,

including in said bath a dye scavenger member consisting of a cellulosic substrate and a dye scavenging material, namely glycidyltrimethylammonium chloride,

and leaving said dye scavenger member in said bath throughout an entire laundering procedure at the conclusion of which the bath and textile materials are separated, whereby any random dye or colorant which dissociates from any of said differently colored textile materials becomes associated with said dye scavenger member and does not discolor in said bath a textile material of a different color from said random dyes and colorants.

12. The method of claim 11, wherein the steps of claim 11 are repeated a plurality of times using the same dye scavenger member.

13. The method of claim 12 wherein said substrate is a non-woven textile member.
