摘要

The mixture containing microfiber cut short article fibrous, and.Mixture containing a polymeric microfiber microfiber cut short not dispersible in water cut short is provided comprising at least one polymer is not dispersible in water in which the polymeric microfiba not dispersible in water has an average thickness less than 1 denier per filam Then, in that a polymeric microfiber cut short not dispersible in water has an aspect ratio of CUp to 300 to about 1000.A process for producing polymeric microfibers not dispersible in water is also provided.The process comprising: a) cutting a multi-component fiber in multicomponent fibers cut; (b) contacting a load of food containing fiber with water to produce a mixture of pulp fiber; when load of food containing multicomponent fibers cut fiber comprises ; (c) heating the fiber mixture of paste to produce a paste of mixture of fiber opciona heated; (d)Lmente, mixing the paste mixture of fiber in a cutting zone; (E) removing at least a portion of the sulfopoliu00e9ster multi-component fiber to produce a mixture of pulp which comprises a dispersion of sulfopoliu00e9ster not dispersible in water and polymer microfibers and F) separating the mic Rofibras polymeric non dispersible in water from the mixture of paste.Processes for producing a non-woven articles are also provided.
