Definitions
- This invention relates to the manufacture and the production of artificial. threads filaments, yarns and the like. hereinafter referred to as threads, from viscose.
- viscose In the production oi artificial threads from viscose, viscose is, extruded through a jet into a coagulating bath containing sulphuric acid and one or more metallic salts.
- the threads are withdrawnfrom the coagulating bath and passed by means. of thread guides over one or more godets, or the threads are. passed on to. one or more. thread-advancing reels where they are treated withv processing. liquids. Insoluble substances are formed, by the reaction which takes. place during the coagulation; andv subsequent. treatment of. the. thread and these. substances are carried away by the. thread and. tend, to form hard deposits on thread guides, godets and thread-advancing reels.
- the object of the present invention isto improve the production ofartificia-l' threads from viscose by preventing the formation of rock-like deposits and incrusta-tions on thread guides, godets or thread-advancing reels and to effect lubrication of the thread during its manufacture.
- the present. invention consists of; aprocess; for
- viscose by extruding: the viscose into a coagulating bath; containing an acid and one or more; metallic salts wherein the thread after leaving the coagulating bath is treated with an oil haying dissolved in
- the presentihvention may conveniently be 5 fill used in a process in which the'threads after leaving the coagulating bath are stretched whilst immersed in a bath of hot dilute acid, for example, as described in U. S. Letters Patent specification No. 2,192,074. With such processes the treatment with the oilhaving dissolved in it the oil-soluble cation-active compound is preferably applied before the thread passes into the bath of hot dilute acid.
- the oil having dissolved in it the oilsoluble cation-active compound is preferably allowed to drip onto the thread while it. is passing over a godet or a thread-advancing'reel.
- the oilemployed is a mineral oil such as that known. as white oil, the term 0' is used. in this specification tocover any organic liquid which may be used for the lubrication of solid surfaces, for exampla vegetable oils, such as olive oil or cotton seed oil and animal oils such as sperm oil. It isdesirable-that the cationactive com-pound shouldbe soluble in the oil being employed. to. such an extent that a clear solution is obtainedbut total solubility is. not essential provided the oil and cation-active. compound may be delivered. to the machine without separation; It; will therefore: be necessary to select a cation-active compound. according to the oil being. used;v The-following classes of cationactive compounds will normally be found sufliciently soluble inthe mineral oil which will be commonly used in practice.
- R is a long chain hydrophobe group with not less than 10 carbon atoms
- R. and R are alkyl groups
- X is an anion, for example Br", ESQ? or CHsCOO
- n is an integer of 2 to 20 according to the chain length of R.
- oil-soluble cation-active compounds for carrying out the present invention are those which will form emulsions when the oil containing the cation-active compound is shaken up with diluteaqueous solutions containing sulphuric acid and one or more metallic salts.
- the process of the present invention is particularly useful in the continuous spinning process in which the thread is withdrawn from the coagulating bath and passed over one or more threadadvancing reels in a number of helical turns, the.
- Figure 1 represents part of a continuous spinning machine
- Figure 2 represents part ,of a centrifugal spinning machine.
- viscose is extruded from the jet 1 from the supply pipe 2 into the coagulating bath 3 toform the thread ii.
- the coagulating bath 3 may conveniently contain sulphuric acid'and one or more metallic salts.
- the thread leaving the coagulating bath 3 passes upwards to the thread-advancing device 5 over which it travels in a number of advancing helical turns. Oil having dissolved in it an oil-soluble cationactive compound is allowed to drip on to the thread 4 from the distributor 6 While the thread is passing over the thread-advancing device 5.
- thread-advancing device 5 On reaching the discharge end of thread-advancing device 5 the thread passes vertically downwards to thread-advancing device '4 and thence'to thread-advancing devices 8, 9 and [0, over each of which it travels in a number of advancing helicalturns. While the thread is travelling over thread-advancing devices l, 8 and 9 it may be subjected to treatment with one or more processing liquids for example, washing, desulphurising and bleaching liquids, the processing liquids being supplied by the distributors H, ifiand l5 and the used processing liquids being collected in drip pans l2, l4 and it.
- the threadadvancing device is supplied internally with steam for heating and drying the thread. The dried thread is collected on a holder H by the cap spinning device I8.
- viscose is extruded from the jet 20 from the supply pipe 2
- the coagulating bath may. conveniently contain sulphuric acid and one or more metallic salts.
- the thread 23 leaving the coagulating bath 22 passes on to the godet'zd by means of thread-guide 24. Oil having vdissolved in it an oil-soluble cation-active compound is allowed to drip from the distributor 26 onto the threadpassing over the godet 25.
- the thread leaving godet 25 passes up to godet 2'5 and is then guided by the spinning funnel 28 into the rapidly rotating box 25) where the thread is collected in the form of a cake.
- the godets 25, 2'1, thread-guide 24 andspinning funnel 28 remain free from rock-like deposits.
- the present invention therefore prevents the formation or rock-likedeposits on threa'd'guides, godets and thread-advancing reels and effects lubricationof the thread while economising in the quantity of oil used.
- Viscose is.- extruded through aj multi-hole jet into a coagulating bath containinglil per cent of sulphuric acid; 1c percent ofsod-ium sulphate and 1 per cent of zinc sulphate.
- the thread is withdrawnfrom the coagulating bath andtpa'ssed onto the delivery end of a thread-advancing reel where it is immediately treated by dripping on it at the rate of 0.25 cm. per minute a per cent solution in mineral oil of a cation-active compound obtained by condensing 1 mol of oleic acid with 1 mol of triethylene tetramine at 180 centigrade for 3 hours.
- the thread is then sprayed with a solution containing 1.5 per centof sulphuric acid, 5 per cent of sodium sulphate and 0.2 per cent of zinc sulphate.
- the thread reaches the discharge end of the reel and then passes on to a second thread-advancing reel.
- the thread has retained suflicient oil to lubricate the second reel and to prevent formation of hard deposits on both reels.
- Emample 2 Viscose thread leaving the coagulating bath is passed on to a thread-advancing reel where it is sprayed at the rate of 0.2 cm. per minute with a 5 per cent solution in olive oil of a cation-active compound obtained by alkylating at room tem perature with 1 mol of dimethyl sulphate the condensation product of 1 mol of palm kernel oil
- the thread is then sprayed with a solution containing 2 per cent of sulphuric acid, 4.2 per cent of sodium sulphate and 0.5 per cent of zinc sulphate.
- the treatment with the oil containing the cationactive compound prevents harmful deposits of sulphur impurities forming on the reel since the oil retained. by the thread lubricates the reel.
- the thread obtained after washing is soft and pliable and does not require soaping.
- Example 3 Viscose rayon thread of 1180 denier, 500 filaments is withdrawn from the coagulating bath and passed round a godet. A 3 per cent solution in mineral oil of a cation-active compound obtained by condensingl part of stearyl ethanolamide with 2 parts of ethylene oxide is dripped on to the thread passing over the godet at the rate of 0.2 cm. per minute. The thread is then passed through a hot dilute acid bath containing from 0.5 to 4 per cent of sulphuric acid, from 1 to 12 per cent of sodium sulphate and from 0. to 1.5 per cent of zinc sulphate and subjected to a stretching as described in U. S. Letters Patent specification No. 2,192,074. The thread retains sufiicient oil, even after its'passage through the stretching bath to prevent deposits on the thread guides and godets over which the thread is passed after leaving the stretching bath.
