Abstract:
A method of making a multicomponent fiber comprising extruding a mixture of:(a) an aliphatic polyester polymer in a weight amount that is between about 45 to about 90 weight percent;(b) polyolefin microfibers in a weight amount that is between greater than 0 to about 45 weight percent phase; and(c) a compatibilizer, which exhibits a hydrophilic-lipophilic balance ratio that is between about 10 to about 40, in a weight amount that is between about 7 to about 25 weight percent, wherein all weight percents are based on the total weight amount of the aliphatic polyester polymer; the polyolefin microfibers, and the compatibilizer present in the multicomponent fiber.
