Abstract (en)
[origin: WO2022139788A1] A base sheet formed from a nonwoven web and having a microstructured topography is provided. A plurality of staple fibers modified with a cation are affixed to the nonwoven web via an adhesive modified with an anion in order to improve one or more attributes of the nonwoven web, such as softness, absorption, abrasion, and barrier properties. The present disclosure also provides a method of forming a base sheet which includes printing the adhesive on the nonwoven web, and passing the nonwoven web through an electroplating module.
