Fibrous articles are disclosed containing an additive composition. The additive composition, for instance, may include a water- soluble film forming component and water-soluble modifying components that is deposited at least at the surface of a fibrous web. In some aspects, the additive composition includes polymers that demonstrate a certain LCST and melting temperature. In another aspect, the additive composition is applied to the fibrous web during the heated drying phase, such as with a Yankee dryer. The fibrous web with additive composition is then creped. The additive composition may improve the perceived softness of the web without substantially affecting the absorbency of the web in an adverse manner. Image
La présente invention concerne des articles fibreux contenant une composition d'additifs, laquelle comprend, par exemple, un composant formant un film hydrosoluble et des modificateurs hydrosolubles, et est déposée au moins sur la surface d'une nappe fibreuse. La composition d'additifs peut également comprendre des polymères avec une certaine température de solution critique inférieure et une certaine température de fusion. Elle peut être appliquée à la nappe fibreuse lors de la phase de séchage par chauffage, par exemple dans un séchoir Yankee. La nappe fibreuse avec la composition est ensuite crêpée. La composition d'additifs permet d'améliorer la douceur perçue de la nappe sans trop en altérer la capacité d'absorption.
