Abstract

A total fiber recovery method and apparatus are disclosed which will recover substantially all of the usable fiber contained in discarded waste material comprising a mixture of fibers, motes and trash. The method consists of conveying the input material into a cleaner and opener which rejects a large portion of the heavy trash and motes. The remaining fiber is transported into a lint cleaner which drops out more motes and smaller trash. From there the partially cleaned fiber is transported to a first cleaner and carder which will clean and orient the fiber. The trash and motes rejected by the cleaner and opener, the lint cleaner, and the first cleaner and carder are collected and cleaned in a drum screen cleaner to remove the heavy trash. The partially cleaned fiber is then transported into a carder and opener where the fibers, including the motes, are fully opened. The opened fiber is then transported to a second cleaner and carder for cleaning and orienting. The outputs of the first and the second cleaner and carder are baled separately to obtain a long fiber fraction and a short fiber fraction respectively.
