Abstract
Use of a material comprising a first polylactic acid and a first non-polylactic acid polyester as a filter base material (2) for a fluid cleaning filter. Furthermore, a method for fabricating a filter base material (2) as well as a filter base material (2) obtainable by the method and a filter comprising the filter base material (2) are provided.
Claims20
A material for a filter base for a fluid cleaning filter, comprising a first polylactic acid and a first non-polylactic acid polyester wherein the first polylactic acid and the first non-polylactic acid polyester are in the forms of fibers, and wherein the material further comprises a binding component for binding the fibers together, the binding component having a lower melting point than the first non-polylactic acid polyester and the first polylactic acid.
A method for fabricating a filter base material, the method comprising:
- carding a material comprising polylactic acid fibers and non-polylactic acid polyester fibers, wherein a single-layered planar fiber web is provided;
- stabilizing the material of the planar fiber web by binding or bonding fibers in the material together, wherein a nonwoven planar fiber web is provided.
