摘要： Multi-ply facial tissue paper products comprising biodegradable chemical softener compositions and a combination of a wet strength binder, either permanent and/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. The multi-ply facial tissue paper products also contain an effective amount of a wet strength binder, either permanent and/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 and/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 and/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.
摘要翻译：公开了包含可生物降解的化学软化剂组合物和永久和/或临时的湿强度粘合剂和干强度粘合剂的组合的多层面巾纸产品。多层面巾纸产品包含可生物降解的化学软化组合物，其包含可生物降解的季铵化合物和多羟基化合物的混合物。多层面巾纸产品还含有有效量的永久和/或暂时的湿强度粘合剂和用于控制棉绒和/或抵消拉伸强度（如果有的话）的损失的干强度粘合剂，使用可生物降解的化学软化组合物。使用永久和/或暂时的湿强度粘合剂和干强度粘合剂也可以改善片材中化学软化组合物的保留性。这导致改善多层面巾纸产品的一个或多个以下性能：柔性，滑粘摩擦系数，FFE-Index和HTR纹理。优选地，大部分可生物降解的化学软化组合物将被布置在多层面巾纸产品的外层上，其中它们是最有效的。换句话说，可生物降解的化学软化组合物和永久性和/或临时性的湿强度粘合剂和干强度粘合剂可以选择性地分布在多层面巾纸产品中以增强柔软性，吸收性和/或特定层或层的棉绒抗性。

摘要： Tissue papers, in particular pattern densified tissue papers, having an enhanced tactile sense of softness when treated with tri-component biodegradable softener compositions are disclosed. These tri-component softener compositions comprise nonionic softeners, nonionic surfactant compatibilizers and polyhydroxy compounds. The weight ratio of the nonionic softeners to the nonionic surfactant compatibilizers ranges typically from about 10:1 to 1:10. The weight ratio of the nonionic softeners to the polyhydroxy compounds ranges typically from about 10:1 to 1:10. The tri-component biodegradable softeners are typically applied from an aqueous dispersion to at least one surface of the dry tissue paper web.
