Abstract
A process for antibacterially finishing a polymeric substrate involving: (a) providing a polymeric substrate made from a compound selected from the group consisting of a polyolefin, a polyester, and combinations thereof; (b) providing an antibacterial finish composition containing: (i) from about 0.1 to 10% by weight of at least one monoester of glycerol and a C6-14 fatty acid; and (ii) from about 0.01 to 10% by weight of chitosan, all weights being based on the weight of the composition; and (c) applying the composition onto the polymeric substrate.
Claims9
A process for the antibacterial finishing of fibers which exclusively or predominantly contain polyolefins or polyesters or nonwovens predominantly containing such fibers, characterized in that the fibers or nonwovens are treated with a water-based composition containing—based on the composition as a whole—
- a) between 0.1 and 10% by weight of at least one monoester of glycerides and a C6-14 fatty acid and
- b) 0.01 to 10% by weight of chitosans and optionally other ingredients.
The use of water-based compositions containing at least one monoester of glycerol and a C6-14 fatty acid and chitosan for antibacterially finishing fibers or nonwovens exclusively or predominantly containing polyolefins or polyesters.
