Abstract
A structured fibrous web having thermally stable, hydrophilic fibers that are thermally bonded together using heat provides a base substrate that is thermally stable. The base substrate is textured via mechanical treatment to increase its thickness and optionally modified via over bonding to improve its mechanical and fluid handling properties. The structured fibrous web provides optimal fluid wicking and fluid acquisition capabilities and is directed toward fluid management applications. The structured fibrous web has a bio-based content of about 10% to about 100% using ASTM D6866-10, method B.
Claims24
A structured fibrous web comprising thermoplastic fibers having a modulus of at least 0.5 GPa forming a fibrous web that is thermally stable;
- the fibrous web comprising a first surface and a second surface, a first region and a plurality of discrete second regions disposed throughout the first region, the second regions form discontinuities on the second surface and displaced fibers on the first surface wherein at least 50% and less than 100% of the displaced fibers in each second region are fixed along a first side of the second region and separated proximate to the first surface along a second side of the second region opposite the first side forming loose ends extending away from the first surface, wherein the displaced fibers forming loose ends create void volume for collecting fluid, and wherein the fibers of the fibrous web are formed from a thermoplastic polymer comprising a polyester, wherein the fibrous web comprises a bio-based content of about 10% to about 100% using ASTM D6866-10, method B.
A structured fibrous web comprising non extendable thermoplastic fibers having a modulus of at least 0.5 GPa forming a fully bonded, non extensible fibrous web that is thermally stable;
- the fibrous web comprising a first surface and a second surface, a first region and a plurality of discrete second regions disposed throughout the first region, the second regions form discontinuities on the second surface and displaced fibers forming loose ends on the first surface, wherein the displaced fibers forming loose ends create void volume for collecting fluid, and wherein the fibers of the fibrous web are formed from a thermoplastic polymer comprising a polyester, wherein the fibrous web comprises a bio-based content of about 10% to about 100% using ASTM D6866-10, method B.
