First Claim
Patent Images
1. A process for making continuous starch filaments, the process comprising steps of:
- (a) providing a starch composition comprising having an extensional viscosity from about 50 Pascal·
second to about 20,000 pascal·
second; and
(b) electro-spinning the starch composition, thereby producing the starch filaments having a size from about 0.001 dtex to about 135 dtex.

Abstract
A flexible structure comprises a plurality of starch filaments. The structure comprises at least a first region and a second region, each of the first and second regions having at least one common intensive property selected from the group consisting of density, basis weight, elevation, opacity, crepe frequency, and any combination thereof. The common intensive property of the first region differs in value from the common intensive property of the second region.

14. A process for making a flexible structure comprising starch filaments, the process comprising steps of:
-
(a) providing a starch composition having an extensional viscosity from about 100 pascal·
second to about 10,000 pascal·
second;
(b) providing a molding member having a three-dimensional filament-receiving side and a backside opposite thereto, the filament-receiving side comprising a substantially continuous pattern, a substantially semi-continuous pattern, a discrete pattern, or any combination thereof;
(c) electro-spinning the starch composition, thereby producing a plurality of starch filaments; and
(d) depositing the plurality of starch filaments on the filament-receiving side of the molding member, wherein the starch filaments conform to the three-dimensional pattern of the filament-receiving side. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22)
