发明名称 Transfer system and process for making a stretchable fibrous web and article produced thereof
摘要 The present invention encompasses a machine direction extensible noncalendered fibrous web produced by a transfer system of at least eight percent negative draw including a matrix of fibrous web material having a wet mullen burst at least about 10 percent greater than a convex transfer system produced web. In addition, the matrix of fibrous material has a wet mullen burst of at least about 74500 pascals. Moreover, the matrix of fibrous web material has a GMBL ranging from about 2047 to about 2704. Furthermore, the matrix of fibrous web material includes fibers, which may be selected from the group consisting of a bonded carded web, spunbonded web, meltblown fiber web, and multi-ply fibrous web. Moreover, the matrix of fibrous web material may have an elmendorf tear greater than about 66.5 centinewton. Also, the matrix of fibrous web material may have a tensile modulus of at least about 1544 gram per centimeter squared. Additionally, the matrix of fibrous web material may have greater strength at lower negative draw percent. Furthermore, the matrix of fibrous web material may have a greater machine direction toughness at about the same GMBL as a convex transfer produced web.
