Abstract: A zone-treated spunbonded/meltblown/spunbonded (SMS) fabric laminate that combines the separate functions of the topsheet and cuff in one component of an absorbent article. The SMS fabric laminate is treated with surfactant to form a hydrophilic zone. The untreated areas of the SMS fabric laminate remain hydrophobic and perform the function of the cuff. Alternatively, a spunbonded/spunbonded fabric laminate is formed and then zone-treated with surfactant. The fabric laminate is treated with surfactant on both sides using a foam applicator. The application of foam produces sharp transitions between the hydrophilic and hydrophobic zones. After foam application, the fabric laminate is dried and slitted. The treated and slitted material is then wound and sold in roll form for converting into the finished disposable diaper.
