Abstract: A removal device (1) for removing a knitted tubular manufacture (20) from a circular knitting machine, comprising an annular removal body (2) which supports a plurality of removal members (3) arranged around the axis (2a) of the removal body (2), the removal body (2) being arrangeable coaxially around the needle cylinder (42) of a circular knitting machine, wherein the removal members (3) are supported by a first annular portion and a second annular portion (2b, 2c) which can rotate with respect to each other about an oscillation axis (100) to pass between a removal condition, in which they are arranged so as to form a circumference that is coaxial with the axis of the removal device (2a), and a sewing condition, in which the annular portions (2b, 2c) are arranged so as to face each other, the first annular portion (2b) supporting a plurality of first removal members (3a), each of which is provided with a first and a second removal element (13a, 13b) which are arranged side by side and are designed, during the removal of the respective loop of knitting from a corresponding needle (44), to be arranged on opposite sides with respect to the corresponding needle (44), the first and second removal elements (13a, 13b) forming a removal head (13) which can move with respect to the respective needle (44) along a movement direction that is parallel to the axis (2a) of the removal body (2), the first removal element (13a) forming, at the removal head (13), a hook-shaped portion (13c) to engage and retain the loop in engagement with the needle (44), and the second removal element (13b) comprising, at the removal head (13), an abutment portion (13d) which can move, with respect to the hook-shaped portion (13c), to disengage from the hook-shaped portion (13c) the respective loop, each first removal member (3a) comprising at least one transfer element (14) which can move with respect to the removal head (13) and is designed to transfer the loop disengaged from the hook-shaped portion (13c) of the first removal member (3a) to a respective second removal member (3b) with the annular portions (2b, 2c) in the sewing condition.A removal device (1) for removing a knitted tubular manufacture (20) from a circular knitting machine, comprising an annular removal body (2) which supports a plurality of removal members (3) arranged around the axis (2a) of the removal body (2), the removal body (2) being arrangeable coaxially around the needle cylinder (42) of a circular knitting machine, wherein the removal members (3) are supported by a first annular portion and a second annular portion (2b, 2c) which can rotate with respect to each other about an oscillation axis (100) to pass between a removal condition, in which they are arranged so as to form a circumference that is coaxial with the axis of the removal device (2a), and a sewing condition, in which the annular portions (2b, 2c) are arranged so as to face each other, the first annular portion (2b) supporting a plurality of first removal members (3a), each of which is provided with a first and a second removal element (13a, 13b) which are arranged side by side and are designed, during the removal of the respective loop of knitting from a corresponding needle (44), to be arranged on opposite sides with respect to the corresponding needle (44), the first and second removal elements (13a, 13b) forming a removal head (13) which can move with respect to the respective needle (44) along a movement direction that is parallel to the axis (2a) of the removal body (2), the first removal element (13a) forming, at the removal head (13), a hook-shaped portion (13c) to engage and retain the loop in engagement with the needle (44), and the second removal element (13b) comprising, at the removal head (13), an abutment portion (13d) which can move, with respect to the hook-shaped portion (13c), to disengage from the hook-shaped portion (13c) the respective loop, each first removal member (3a) comprising at least one transfer element (14) which can move with respect to the removal head (13) and is designed to transfer the loop disengaged from the hook-shaped portion (13c) of the first removal member (3a) to a respective second removal member (3b) with the annular portions (2b, 2c) in the sewing condition. Process for processing and utilization of waste liquor containing at least polyester decomposition products from an alkaline digestion process to obtain a cellulose raw material from mixed textile waste which contains at least a cellulose component and a polyester component. In order to make the process more environmentally friendly and more economical with resources, according to the invention, the process comprises the following steps: evaporation of water from the waste liquor to precipitate the polyester decomposition product from the waste liquor and obtain a biphasic mixture having an aqueous phase and a solid phase containing the polyester decomposition product, b) separation of the solid phase from the aqueous phase and c) thermal/energetic recovery of the solid phase.
