Latest Patents
Doris holds a patent for "Multicomponent biodegradable filaments and nonwoven webs formed therefrom." This invention provides a biodegradable, substantially continuous filament that consists of a first component made from at least one high melting polyester and a second component made from at least one low melting polyester. The low melting point polyester is an aliphatic-aromatic copolyester created by melt blending a polymer and an alcohol, initiating an alcoholysis reaction. This process results in a copolyester with hydroxyalkyl or alkyl terminal groups. By controlling the alcoholysis conditions, a modified aliphatic-aromatic copolyester can be achieved, which has a lower molecular weight than the starting polymer. These lower molecular weight polymers exhibit a higher melt flow index and lower apparent viscosity, making them suitable for forming continuous filaments.
