TH28872A - Method for the production of lyocell fibers - Google Patents

Abstract

DC60 (06/10/40), control over the biocell bias bias bias. Fineness may be achieved by using a solution of the metal. Alkali hydroxide in water and the fibers in a condition that has never been dry under Under the conditions in which the longitudinal shrinkage of the fibers during this process was controlled at a value within the range of 5 to 20%, control over the biocell bias bias bias may be achieved by using Metal solution Alkali hydroxides in water and fibers In conditions that never dry under Under conditions which cause longitudinal shrinkage of the fibers during the procedure This is controlled at a value within the range of 5 to 20%.

Claims (1)

1. Methods for producing lyocell fibers including sequential steps. 1) Extruding of cellulose solution in organic solvent One kind through a die For this reason it is produced as a stretched pattern. 2) At least one pass through a bath filled with water. To eliminate organic desiccants from stretched forms For this reason it produces Is lyocell fibers that never dry out; 3) Using a solution of alkali hydroxide in water With lyocell fibers that never dry out; 4) Washing of never-dried lyocell fibers to remove metals. Alkali hydroxides from there, and 5) Making fiber tag:
