Definitions

  • cellulose compounds which I may use the following are given: cellulose acetate, cellulose nitrate, nitro-acetyl cellulose, alkyl-, aryl-, or aralkyl '2 ethers of cellulose, in acetone, ether, alcoholether, acetic acid and other mixed or nonmixed ethers or esters of cellulose in volatile solvents or mixtures of solvents.
  • the object of my present invention is to provide a process whereby it is possible to obtain artificial textile products with reduced luster from cellulose directly (i. e. without any after-treatment and also to obtain any degree of reduction of the luster.
  • the said result is obtained by carrying out the spinning process in the presence of water, which term also includes water vapour, in the use of the so called drying or evaporative method.
  • My invention may be realized in difierent ways.
  • A. sufiicient amount of water may be maintained in the spinning cell, and the spun I be added if a duller product is desired, and a material may be introduced, before the threads are wholly deprived of the solvent, into a second room in which suflicient water vapour is present.
  • the object in View may be attained by using a spinning solution to which water has been added and of which theviscosity' has been brought back to the normal.
  • a spinning solution to which water has been added and of which theviscosity' has been brought back to the normal.
  • the solution of cellulose acetate in aceton is introduced into a spinning cell in a downward direction, through fine apertures, the spun material being led along a thread guide to the winding apparatus.
  • the spinning process is carried out in the presence of water or, alternatively, in the presence of water vapour.
  • the spinning process may be carried'out 'in such a way that water vapour is present in the spinning'cell, the amount of water vapour increasing with the rise of temperature.
  • water vapour is not introduced into the spinning cell, the spun material being led out of the spinning cell before the solvent is completely removed, and
  • I may, for example, use a second cell or the winding apparatus may be arranged in a moist atmosphere or the'spun material may be freed from the acetone in a room inwhich water vapour is present, during its travel from the spinning cell to the winding apparatus.
  • the product obtained will be more or less "dull, the degree of dullness depending upon the length of the way over which the spun material is led into the damp atmosphere and also upon thedegree of humidity and the temperature of the air.
  • I v I A small proportion of water may also be added to the spinning solution, the proportion of water depending amongst other things, upon the degree of dullness which is desired to be attained andupon the temperature in the spinning cell.”
  • the silk becomes glossy, so that more water has to be added, and, in order to maintain the same viscosity, also more benzene.
  • a process for the preparation of artificial textile products with diminished luster from cellulose compounds consisting of dissolving the cellulose compound in a volatile solvent, introducing the solution into a spinning cell, evaporating the volatile solvent the spinning cell, the proportion of such water being dependent upon the degree of dullness required in the product.
