SHORT CUT MICROFIBERS |
摘要 |
A short-cut, water non-dispersible polymer microfiber is provided comprising at least one water non-dispersible polymer wherein the water non-dispersible polymer microfiber has an average fineness of less than 1 denier per filament; and wherein said water non-dispersible short-cut polymer microfiber has an aspect ratio of about 300 to about 1000. A process for producing water non-dispersible polymer microfibers is also provided, the process comprising: a) cutting a multicomponent fiber into cut multicomponent fibers; b) contacting a fiber-containing feedstock with water to produce a fiber mix slurry; wherein the fiber-containing feedstock comprises cut multicomponent fibers; c) heating the fiber mix slurry to produce a heated fiber mix slurry; d) optionally, mixing the fiber mix slurry in a shearing zone; e) removing at least a portion of the sulfopolyester from the multicomponent fiber to produce a slurry mixture comprising a sulfopolyester dispersion and water non-dispersible polymer microfibers; and f) separating the water non-dispersible polymer microfibers from the slurry mixture. Processes for producing a nonwoven article are also provided. |
