A method of producing lyocell fibers by spinning a solution of cellulose in an organic solvent through an air gap and into a spin bath in which there is provided a cross-draught of air in the air gap.

Process of making cellulose filaments

A method of producing lyocell fibres by spinning a solution of cellulose in an organic solvent through an air gap and into a spin bath in which there is provided a cross-draught of air in the air gap.

A spinnerette for the spinning of fibres has a rectangular frame with an upper flange for connection to a jet assembly and a lower planar apertured plate for the passage of spinning dope, the apertured plate being formed with its spinning holes and then electron beam welded into the bottom of the frame from the outside.

Spinnerette

A spinning cell for producing lyocell fibre by spinning a solution of cellulose in an organic solvent through an air gap into a spin bath has nozzles to create a cross-draught through the air gap.

Spinning cell

Staple fibres of solvent-spun cellulose are made by a method in which:

Method of making crimped solvent-spun cellulose fibre

A jet assembly for spinning cellulose fibres from a solution of cellulose in an amine oxide solvent in which the jet assembly includes a generally top-hat shaped spinnerette having a series of downwardly directed holes through the base of the spinnerette and an outwardly directed flange around the periphery of the vertical walls of the spinnerette, the jet assembly including a heated housing engaging with the flange and being bolted to the flange, insulation being provided on the underside of the jet assembly over the outer periphery, the combination of heating and insulation regulating the temperature of the jet assembly for optimum spinning of an amine oxide cellulose solution.
