Abstract
Disclosed herein are articles produced from the vitrification of uncross-linked alkyd oligomers. The articles include fibers, nonwovens, and articles made from nonwovens such as, for example, diapers, wipes, feminine hygiene articles, drapes, gowns, sheeting, and bandages. Also disclosed herein is a method for making articles composed of uncross-linked alkyd oligomers.
Claims20
An article comprising a fiber having an equivalent diameter that is less than about 200 μm and a lengthwise dimension that is at least 20 times the equivalent diameter, the fiber comprising uncross-linked alkyd oligomers.
A method comprising:
- (a) liquefying uncross-linked alkyd oligomers to result in a melt having a viscosity of about 0.1 kg m−1 s−1 to about 20 kg m−1 s−1;
- (b) pumping and spinning the melt through a die having an effective diameter of less than about 1000 μm, without inducing cross-linking, to form molten fibers;
- and
- (c) vitrifying the molten fibers without inducing cross-linking.
