Definitions

• This invention relates to the manufactureof artificial threads and more particularly to artificial threads containing sulfur and nitrogen.
• This invention relates to a process of making artificial fibers from derivatives of cellulose containing nitrogen and sulfur by first spinning the ordinary viscose by means of a usual spinning bath to produce threads containing cellulosfe Xanthate and then treating the threads, either directly or, if desired, after purification in a second bath which may consist, for example, of a neutral or feebly acid salt solution, with ethyleneimine or a homologue thereof which reacts analogously to the said imine or homologue or another cyclic nitrogeneous base or a salt of any of these.
• the cyclic nitrogeneous base may be applied in the form of vapour or liquid or dissolved in water or another solvent. It has been found that both the free bases and their salts can react with the Xanthate groups so that, for example, basic, neutral or acid solutions of the bases may be used as the reaction bath.
• Artificial fibers produced by this invention from cellulose derivatives containing nitrogen and sulfur have properties similar tothose of wool. In particular they can be dyed in admixture with wool with the usual wool-dyestufis in the same degree of fastness. The tensile strength and extension of the new artificial fibers do not fall behind those normal for cellulose artificial fibers.
• Example 1 -Normal viscose, ripe for spinning and containing about 25 Xanthate-groups per C6 molecules of cellulose, is spun in a bath containing a 32 per cent solution of sodium sulfate and 4.2 per cent of sulfuric acid at a temperature of 35 C. to produce a bundle of Xanthate threads; this bundle is then treated in a washing bath consisting of a 30 per cent solution of sodium sulfate at 50 C. The bundle of thread is now squeezed and passed in this condition through a chamber at 50-60 C. in which ethylene-imine vapour is circulating, whereby the reaction of the xanthate groups contained in the coagulated bundle of threads with the ethyleneimine is completed in a few seconds. The bundle of threads is then washed in a bath of 5 per cent of sulfuric acid, washed with water and revived. The dried threads contain 1-1.2 per cent of nitrogen and can be dyed with acid wool-dyestuffs.
• Example 2 Viscose having about 50 xanthategroups per 100 cellulose Cir-molecules is spun by any usual method to a xanthate thread and the bundle ofthreads is passed through an aqueous solution of percent strength of Nmethylethyleneimine, which is feebly acid with sulfuric acid and may be mixed with an inorganic salt. During the gradual complete winding of the spool or the reel on which the bundle of thread is taken up the N-methylethylene-imine has time to react with the xanthate groups. The fibrous material thus obtained has an afiinity to wool-dyestufis and a nitrogen content of 2.8 per cent.
• Example 4 --Viscose containing about 25 xanthate-groups per 100 Cs molecules of cellulose is coagulated in a bath containing 30 per cent of sodium sulfate and 2 per cent of sulfuric acid at a temperature of 60 C.
• the length of immersion of the thread in the bath is 15 cm. and the speed of draft 40 ms. per minute.
• the thread contains free xanthate-groups and is washed following the spinning process in a bath consisting of a per cent solution of sodium sulfate and then through a bath of a 20' per cent aqueous solution of ethylene-imine. Then the bundle of threads is passed through a chamber heated at 60 C. in which it remains about 15 seconds.
• the dried fibers contain 1.8 per cent of nitrogen and 4.5 per cent of sulfur.
• a process of producing artificial threads containing nitrogen and sulfur which comprises spinning viscose into a precipitating bath containing at most 4.2 per cent of acid to form threads consisting of cellulose xanthogenate and reacting on the formed threads with a cyclic ethyleneimine.
