Tissue products are described that have been topically treated with a chemical additive, such as a softener. The softener may be, for instance, a polysiloxane. The polysiloxane is topically applied to a tissue sheet, such as a single ply sheet, so as to form a Z-directional gradient in the sheet. Particular, most of the polysiloxane remains on the surface of the tissue product as opposed to migrating to the center of the sheet. In this manner, tissue sheets are formed with improved softness at lower levels of polysiloxane and without the need for applying any surfactants to the sheet. A system for applying chemical additives to tissue sheets is also described. The system includes a chemical additive applicator, such as a meltblown die that emits the chemical additive through a plurality of orifices. In one embodiment, the system includes a device for periodically cleaning the orifices during application of the chemical additive. The cleaning device may be, for instance, a brush that traverses across the die head when desired.

L'invention concerne des produits en papier tissu ayant été traités localement avec un additif chimique, tel qu'un adoucisseur. L'adoucisseur peut être, par exemple, un polysiloxane. Ce polysiloxane est appliqué localement sur une feuille de papier tissu, telle qu'une feuille monocouche, de sorte qu'un gradient dans le sens Z soit obtenu dans la feuille. En particulier, la plupart des siloxanes restent à la surface du produit en papier tissu au lieu de migrer vers le centre de celle-ci. Ainsi, les feuilles de papier tissu formées présentent une douceur accrue avec des faibles taux de polysiloxane, sans qu'il soit nécessaire d'appliquer des agents tensioactifs sur la feuille. Un système d'application d'additifs chimiques sur les feuilles de papier tissu est également décrit. Ce système comprend un applicateur d'additif chimique, tel qu'une filière produite par fusion et soufflage qui diffuse l'additif chimique par plusieurs orifices. Dans un mode de réalisation, le système comprend un dispositif conçu pour nettoyer périodiquement les orifices pendant l'application de l'additif chimique. Le dispositif de nettoyage peut être, par exemple, une brosse qui traverse la tête de la filière lorsqu'on le souhaite.
