Definitions

  • This invention relates to the art of manufacturing rayon thread.
  • this art it has been proposed to provide a continuous process -wherein the thread from the time of its precipitation goes through all of the remaining steps of the process without interruption, but insofar as I'am aware, none of these proposed continuous processes have been practical or successful, and all rayon is, at this time, manufactured by non-continuous processes.
  • Another object of the invention is to provide apparatus for carrying out said process.
  • Fig. 1 is a side elevation of the preferred form of apparatus employed in carrying out the process when cupro-ammonium thread is to be made.
  • Fig. 2 is a partial side elevation and section through a pprtion of apparatus employed in carrying out the process.
  • Fig. 3 is an end elevation of Fig. 2.
  • Fig. 4 is a similar side elevation, also in more or less diagrammatic form, illustrating a modification of the invention.
  • Figs. 5, 6 and 7 illustrate certain details which may be employed.
  • Fig. 1 is the preferred form of apparatus to be employed in making such silk.
  • the reference numeral '7 indicates the pipe line leading from a source of supply of copper ammonia cellulose solution (not shown), the reference numeral 8 indicates the pump and the reference numeral 9 a suitable form of spinneret adapted to spin a multiplicity of filaments.
  • the precipitating bath is indicated at 10, the spinneret 9 being adapted to be im- 1931, Serial No. 508,840
  • the bath 10 is a caustic soda bath.
  • the thread or bundle of filaments 11 passes over the guide 12 as it leaves the bath and over other suitable guides 13 and 14 to what, for lack of a better term, may be designated as a squirrel cage drum 15.
  • This drum is adapted to be rotated by any suitable power means 16, and, as will hereinafter appear, when the thread is started thereon, it winds up and, as it winds, travels toward the upper end of the drum from which the thread is led over suitable guides 17, 18, to any suitable known type of twister-mechanism 19 by means of which it is laid up upon a spool 20 with twist.
  • the thread goes on to the drum in the form of a single layer, with the thread not contacting with itself at any point along the length of the drum, so that the thread will be effectively exposed for the various treatments which it must undergo before being finally laid up upon the spool 20 in conditioned form. It will also be seen that the thread as it is drawn from the bath by the drum continuously moves up the drum and is continuously drawn off at the upper end thereof.
  • the thread is dried as by means of a current of mildly warm air delivered by the pipe 25 so as to discharge against the thread.
  • the thread as it leaves the drum is completely conditioned. and, as before stated, is
  • the water which is dripped farther along the drum merely washes from the thread the copper sulphate, together with excess acid, should there be any. This mingles with the acid drip, forming a mixture which progressively becomes less and less acid as it moves down the drum until, finally, it is neutral.
  • the mixture in which the copper sulphate is in solution meets caustic carried up by the oncoming thread and the caustic soda precipitates copper hydroxide with sodium sulphate as a by-product.
  • the copper hydrate precipitate remains in suspension in the mixture of liquids flowing down, which mixture also still contains the other salts.
  • the mixture in flowing farther down dilutes and removes a large portion of the caustic soda progressively so that no caustic soda reaches the acid area which permits the use of the minimum amount of acid.
  • the mixture drops off the lower end of the drum and is collected in the pan 26 and carried by pipe 2'7 to a suitable tank for recovery.
  • the ammonia which is carried up from the bath by the thread is held in solution by these liquids and does not go off, making it easy to recover.
  • the thread As the thread moves up the cylinder and is acted upon by the acid and water and the mixture thereof, it gradually becomes deflated through the removal of caustic soda, water and copper hydroxide, the deflation being about complete at the point where the water is dropped upon the drum. Deflation of the thread results in some elongation thereof which gradually and increasingly occurs as deflation proceeds to completion. This elongation of the thread would result in loosening of the thread upon the drum and the contacting of one portion of the thread with other portions.
  • the drum is composed of a plurality of longitudinally extending bars which are made hollow for purposes of lightness and are composed of Monel or other suitable resistant metal. Every alternatebar 28 is carried at one end by a disk 30 and at the other end by a similar disk 31 through the medium of pins 32 which are threaded into the disks and project radially therefrom and enter into holes provided in the bars. The bars are secured to the ends of the pins as by a wire indicated at 33, or other preferred means, providing universal motion.
  • the other bars 29 are carried at one end on a disk 34 and at the other end on a similar disk 35, by means of pins 32, as before.
  • a drive shaft composed ofthree sections 36, 37 and 38 coupled with universals 39 is provided.
  • Bearings 40 are provided for the two end sections,
  • the disks 34 and 35 are mounted on ball bearings 41' eccentric and inclined to the shaft sections 36 and 38 and are oppositely canted in like amount.
  • the bars 29 progressively recede toward the center, being at their lowest point (i. e., nearest the axis of rotation of the shaft sections 36 and 38) at the horizontal plane of said axis, as shown in Fig. 3 at the right.
  • the bars 29 gradually move outwardly until, at the top, they are in substantially .the same plane as the bars 28. From this point on, as. rotation continues, the bars 29 advance beyond the plane of the bars 28, as shown at the left of Fig. 3, and then gradually come back to the plane of the bars 28, and so on.
  • the starting of the thread can be accomplished very readily. For example, one way is to pass the thread around the drum and turn under the end thereof so that the run of the thread on the drum will hold the end while the drum is running.
  • Another way is to loosely loop the end of the thread around one of the bars, which causes the following thread in the next succeeding turn to overlap and the ring of thread thus formed moves up the drum.
  • Fig. 4 The arrangement of Fig. 4 is substantially the same as that of Fig. 1 and may be employed where it is desirable to separately collect fluids employed in chemical treatment.
  • the trough 26a has a plurality of compartments, each having a discharge pipe 27a.
  • Suitable means is provided for securing the dropping off of respective fluids into the respective collecting compartments.
  • One such means may be the provision of ribs 43 on the outer face of the bars.
  • the thread has no twist until that which is imparted by the fiyer 19.
  • no difficulty is encountered in connection with spreading of the filaments for the reason that the thread on the drum carries liquids and is only contacted at spaced points.
  • the surface tension of the liquid intermediate the points of contact serves to hold the filaments together.
  • the blower pipe 25, for convenience of illustration, is shown at the top of Fig. 1. It is preferable to locate it at the side and to have its discharge orifice in the form of a slot extending longitudinally of the drum.
  • some of the drying air enters into the interior of the drum and some of the air plays upon wet portions of the thread and other portions upon relatively drier parts of the thread, with the result that the air to which the thread is subjected never becomes completely dry, the drier portions being leavened by the portions which have picked up some humidity from the wet thread.
  • the air within the cylinder because of the inclination, flows toward the upper end thereof and thus complete drying of the air and of the thread is avoided, which eliminates the presence of static.
