A PROCESS FOR SEPARATING A FIBROUS TARGET COMPONENT FROM TEXTILE WASTE

A process (1, 101, 201) for separating a fibrous target component (21) from textile waste (2, 5) is shown, said textile waste (2, 5) containing the target component (21) and at least one ancillary component (22), whereby the target component (21) consists of water-swellable textile fibers (51) with a density higher than the density of water, the process (1, 101, 201) comprising the steps: a) dispersing the comminuted textile waste (5) in an aqueous solution (7) to obtain a suspension (8) containing the textile waste (5), and b) separating the dispersed textile waste (5) into a high-density target fraction (81) comprising the target component (21), and a low-density residual fraction (82) comprising the at least one ancillary component (22), according to the respective density of said components (21, 22). In order to provide a reliable, fast process for the separation of water-swellable fibers from other textile fibers which are similar in density, it is proposed, that the aqueous solution (7) is an alkaline aqueous solution (7) and the target component fibers (51) are swelled in the alkaline aqueous solution (7) prior to step b), thereby increasing the density and weight of said target component (21) relative to the density and weight of the ancillary component (22).

CENTRIFUGAL FIELD-FLOW FRACTIONATION DEVICE
20200122158 · 2020-04-23 · ·

Provided is a centrifugal field-flow fractionation device in which a liquid sample is less likely to leak from a channel and attachment and detachment work of a channel member is facilitated. By integrally forming an outer peripheral surface 162 and an inner peripheral surface 163 of a channel member 16, the channel member 16 is configured as one hollow member having a channel 161 formed inside. Thus, pressure resistance performance of the channel member 16 is improved, formation of a gap in the channel 161 can be prevented, and deterioration in sealing performance due to secular change is not generated. Accordingly, a liquid sample is less likely to leak from the channel 161. Further, since the channel member 16 can be handled as one member, attachment and detachment work of the channel member 16 is facilitated.
