Abstract
A thermoplastic layer material has at least one odor reducing surface which is treated with a carboxylic acid-based odor control agent, and which is able to withstand insults with an aqueous liquid. The acid-based odor control agent is bound to the layer material by an organosilicone polymer binder. The binder is water-insoluble, and can form a highly gas-permeable coating. The binder is also highly porous, so as to expose the odor control agent to ammonia and other odoriferous gases which it is intended to control.
Claims48
A treated thermoplastic layer material comprising:
- a thermoplastic substrate layer;
- an odor control system on the substrate layer, including a carboxylic acid-based odor control agent;
- and
- a binder on the substrate layer, including an organosilicone polymer.
A treated thermoplastic layer material, comprising:
- a thermoplastic substrate layer;
- about 0.1-10%, based on the weight of the treated layer material, of an odor control system including a multi-carboxylic acid-based odor control agent;
- and
- about 5-200 parts by weight of silicone polymer binder per 100 parts by weight of the odor control system.
A treated thermoplastic layer material, comprising:
- a fibrous nonwoven substrate layer;
- an odor control system on the substrate layer, including a hydroxycarboxylic acid and chitosan;
- and
- a binder on the substrate layer, including an organosilicone polymer.
