  • Patent number: 5981044
    Abstract: Multi-layered tissue paper webs comprising biodegradable chemical softener compositions and binder materials are disclosed. The multi-layered tissue webs are useful in the manufacture of soft, absorbent paper products such as facial tissues and/or toilet tissues. The multi-layered tissue paper products contain a biodegradable chemical softening composition, preferably comprising a mixture of an ester-functional quaternary ammonium compound and a polyhydroxy compound. The multi-layered tissue paper webs also contain an effective amount of binder materials to control linting and/or to offset the loss in tensile strength, if any, resulting from the use of the chemical softening compositions. Preferably, the majority of the biodegradable chemical softening compositions will be disposed on the outer layers of the multi-layered tissue paper products where they are most effective at enhancing softness.

  • Patent number: 5958802
    Abstract: The invention is basically ultra thin webbing that has been coated with a pressure sensitive adhesive that easily releases from the material. The webbing is manufacturer by producing an ultra thin webbing and the placing that webbing in a vat of pressure sensitive material that produces a coating on the webbing that enables the webbing to be attach to a material and also to be easily removed from the material. The webbing is coated such that the adhesive is on both side of the webbing and thus the webbing can be attached to materials on either side or both. The material is produced in sandwich form in which a release paper is attached by pressure to both sides. When an individual wishes to transfer a pattern to fabric the individual removes the release paper from one side of the webbing. Then the individual places the pattern on the webbing. Then one removes the other release paper and places the side not attached to the pattern against the fabric.
