June 19, 1-956 THREAD ADVANCING REEL HAVING LIQUID APPLICATOR AND WIPER J. H.. GIVENS ET AL Filed June 18, 1952 INVENTORS JOHN HARRISON GIVENS, LESLIE ROSE a JOHN WALE BY LQM J M ATTOR N EY THREAD ADVANCING REEL HAVING LIQUID APPLICATOR AND WIPER John H. Givens, Meriden, Leslie Rose, Whitefield, and John Wale, Coventry, England, assignors to Industrial Rayon Corporation, Cleveland, Ohio, a corporation of Delaware Application June 18, 1952, Serial No. 294,172 4 Claims. (CI. 68-19) This invention relates to the production of artificial threads by wet spinning.
In one of the so-called continuous spinning processes for the production of artificial threads, it is known to extrude a fiber-forming solution such as viscose into a coagulating bath to form a thread which is then carried on a pair of cylindrical rollers, the axes of which are skewed with respect to one another so that the thread advances along the rollers in a helical path, and to subject the thread as it advances over the rollers to one or more aqueous liquid treatments, suitable provision being made where necessary to maintain the liquid zones separate. The processing liquids have usually been supplied directly to the rollers by means of supply pipes. With processes of this kind there is a maximum operational speed, usually of the order of 80 to 100 meters per minute, because at speeds higher than the maximum the processing liquid is flung off the rollers by centrifugal action at the point where it is applied and consequently thereis no progressive liquid treatment such as washing on the rollers.
The object of the present invention is to provide an improved method of supplying treating liquids to roller machines which permits the use of increased spinning speeds. r
According to the present invention, there is provided a method and an apparatus for treating with liquid a thread-advancing in helical turns over a pair of rollers which comprises supplying the treatment liquid to one or more surfaces which touch the thread pack so that the liquid is taken up by the travelling thread and removing excess liquid from the thread pack by leading it into contact with one or more additional surfaces which also touch the thread pack. In this specification, the term thread pac is used to denote the complete set of helices of thread which are undergoing treatment in the liquid treatment zone.
The thread-advancing rollers are preferably arranged one vertically above the other with the liquid-supplying and applying surface or surfaces positioned between them on the side of the thread pack travelling upwards, and the liquid-removing surface or surfaces similarly positioned on the other side of the thread pack, that is the thread travelling downwards. With this arrangement the liquid is supplied to the thread pack by one or more surfaces on its upward travel, carried over the top roller and then downwards until it is removed by the other oppositely positioned surface or surfaces.
The supplying and wiping surfaces may conveniently take the form of glass rods slightly inclined to the horizontal, the treating liquid, for example water, being dripped on to one end of the liquid-supplying surface so that the liquid runs down the rod into contact with the thread pack. A similar rod on the other side of the thread pack serves to remove excess liquid. In other forms of the invention, small rotating rollers may be used as the liquid applying and removing surfaces, or a single rotating roller may be provided between the helices of thread,
nited States Patent 9 the treatment liquid being supplied to one side of the roller.
The invention also includes a machine for the production of artificial threads comprising a pair of rollers, the axes of which are skewed with respect to one another so that thread may be advanced in helical turns over the rollers, one or more treating liquid supplying and applying rods or rollers having surfaces so arranged as to touch the thread pack between the rollers, means for supplying liquid to the said applying surfaces and one or more additional rods or rollers having surfaces which are also so arranged as to touch the thread pack for removal of excess liquid from the thread pack.
The present invention may be used for carrying out either a single liquid treatment or a number of different treatments by using groups, each consisting of two sets of surfaces for each particular treatment. It is an advantage of the present invention that the surfaces confine the treatment liquid to the zone covered by the surfaces and thus to the thread pack,and it is therefore unnecessary to make further provision for separating the liquids. The machines according to the invention operate successfully at speeds as high as meters per minute.
An example of a machine in accordance with the invention is illustrated in the accompanying drawings in which:
Figure l is a longitudinal section of the machine;
Figure 2 is a plan view of the processing portion of the machine; and
Figure 3 is a modification of the thread treating portion of the machine of Figure 1.
Viscose from a main supply pipe 1 is passed through a pump 2 and a candle filter 3 and is extruded from a jet 4 into a coagulant bath 5 to form a thread 6. The thread 6 leaving the bath 5 passes through a thread guide 7 then to a godet 7A, then on to the stepped end 8 of a roller 9. The thread 6 passes round the stepped end 10 of a second roller 11 and after passing round the stepped ends 8, 10 for two turns it is led on to the main part of the rollers 9, 11 by a thread guide 12. The roller 11 is canted slightly with respect to roller 9, as shown in Figure 2 so that the rollers together constitute a threadadvancing device on which the thread travels ina number of advancing helical turns. The rollers 9, 11 are fixed on shafts 13, 14 and are driven through suitable gearing in a housing 15. The thread travels over thefirst part of the rollers 9, 11 without any liquid treatment to allow regeneration of the cellulose in the thread to continue. Beyond the regeneration stage the thread 6 is washed with water supplied by a pipe 16 to a rod 17 of glass, or of other corrosion resisting material or glass or wettable or the like surfaced, which lightly touches the thread pack as it travels upwards. Water so suplied runs down the rod 17 and is taken up by the thread pack over the roller 9 and removed by a second rod 18 which just touches the thread as it travels downwards. A drip pan 19 is provided below roller 11 to collect the wash liquor removed by the rod 18. The thread leaving the rollers 9, 11 is dried on a drying device consisting of an internally heated rotating roller 20 and an unheated auxiliary roller 21. The dried thread is collected as a package on a holder 22 by a cap spinning device 23.
Instead of the stationary rods 17, treating liquid supplying rollers can be utilized. As shown in Figure 3 a treating liquid is supplied by a feeding roller 33 to a thread helix being formed and advanced by a reel comprising the skewed spaced rollers 25 and 27 mounted on shafts 29 and 30 supported in an end support 31. A liquid supply 32 spills a treating liquid onto the surface of the roller 33 rotated oppositely to the travel of the thread turns by a power means 34. The liquid flows along the roller surface by force of gravity to be picked up by the plurality of'consecutive turns of the thread helix with which his in'contact. A similar roller (not shown) is located on the opposite side of the helix for wiping off the excess from that helix portion with which it is in contact. These rollers 33 can be positioned withinthe travellinghelix and in contact therewith if desired. However, it is more convenient to have them in external contact with the helix. The-present invention is illustrated by the following example directed to the treatment of viscose rayon threads; percentages are by weight.
Example Viscose containing 8 per cent of cellulose and 6 per cent of sodium hydroxide and having a salt-point of 6.0 was extruded into a coagulant bath through a jet containing 16 holes of inch diameter to produce a 60 denier thread, the coagulating bath being at 60 centrigrade and-containing '9 per cent of sulphuric acid, 20 per cent of sodium sulphate and 1 per cent of zinc sulphate.
The thread was withdrawn from the bath .at a rate of a'bout 130 meters per minute by the godet 7A then passed to a pair of canted thread-advancing rollers 9, 10, having a peripheral speed of 150 meters per minute. The rollers were cylindrical, 45 inches long, 7 inches in diameter, and were arranged one above the other, 18 inches apart with lower roller at an angle of 3 from the horizontal tilting downwards towards the entrance end of the rollers. Over the first 21 inches of the rollers 9, 11 the thread was advanced without any liquid treatment at all so as to complete regeneration of the thread. Approximately midway between the rollers on both sides of the thread, two glass rods 17, 18 were provided, both rods being at an angle of about 7 to the horizontal and arranged so that they just touched the turns of the thread. The rods 17, 18 are projected for a distance of about two feet from the discharge end of the rollers so that the thread pack in the washing zone also extended for about two feet. Water at a rate of about 150 ccs. per minute was supplied to the rod in contact with the turns of thread passing vertically upwards so that'the water passed down the rod and was taken up by the thread; the glass rod 18 in contact with the thread passing vertically downwards removed most of the liquid adhering to the thread after it left the top roller 9. The water did not pass beyond the end of either of the glass rods 17, 18. The washed thread leaving the rollers 9, 11 was passed -toa heated thread-advancing reel 20 to dry it and the dry thread was collected on a cap twisting device 23 in known manner.
