    摘要： Multi-ply facial tissue paper products comprising biodegradable chemical softener compositions and a combination of a wet strength binder, either permanent or temporary, and a dry strength binder is disclosed. The multi-ply facial tissue paper products contain a biodegradable chemical softening composition comprising a mixture of a biodegradable quaternary ammonium compound and a polyhydroxy compound. Preferred biodegradable quaternary ammonium compounds include diester dialkyl dimethyl ammonium salts such as diester di(touch hardened)tallow dimethyl ammonium chloride and/or diester di(touch hardened)tallow dimethyl ammonium methyl sulfate. Preferred polyhydroxy compounds are selected from the group consisting of glycerol, polyglycerols having a weight-average molecular weight of from about 150 to about 800, polyoxyethylene glycols and polyoxypropylene glycols having a weight average molecular weight from about 200 to 1000. The multi-ply facial tissue paper products also contain an effective amount of a wet strength binder, either permanent or temporary, and a dry strength binder to control linting and/or to offset the loss in tensile strength, if any, resulting from the use of the biodegradable chemical softening compositions. The use of both wet strength binder, either permanent or temporary, and dry strength binder also improves the retention of the chemical softening composition in the sheet. This results in improving one or more of the following properties of the multi-ply facial tissue paper product: the flexibility, the slip-stick coefficient of friction, the FFE-Index and the HTR-Texture. Preferably, the majority of the biodegradable chemical softening compositions will be disposed on the outer layers of the multi-ply facial tissue paper products where they are most effective. In other words, the biodegradable chemical softening compositions and the wet strength binder, either permanent or temporary, and the dry strength binder can be selectively distributed within the multi-ply facial tissue paper product to enhance the softness, absorbency, and/or lint resistance of a particular layer or ply.

    摘要： A multiple ply paper web (10) comprising at least one outer cellulosic ply (30), preferably two outer cellulosic plies (30) passively bonded to at least one inner ply (20). The inner ply can be comprised of meltblown fibers formed into a liquid-impermeable, breathable nonwoven web. The tissue plies can be creped tissue paper having a basis weight of from about 10 g/m2 to about 100 g/m2, preferably from about 15 g/m2 to about 25g/m2. In a preferred embodiment, the meltblown fibers of the inner ply comprise polypropylene fibers having an average diameter of less than about 10 microns, and more preferably less than about 2.5 microns. The nonwoven web can have a basis weight from about 1 g/m2 to about 15 g/m2, preferably from about 1 g/m2 to about 10 g/m2, and more preferably from about 1 g/m2 to about 8 g/m2. In a preferred embodiment the inner ply has a Moisture Vapor Transmission Rate of at least about 4000, and can hold a hydrostatic head of at least about 20 mm H¿2?O.
