Definitions

  • This invention relates .to the production of artificial threads by the cup'ro-ammonium stretch spinning process; and has for its pr1ncipal ob ect to improve the quality of. the threads obtained.
  • the invention relates more particularly to that part of the process in wh ch the threads are subjected to an acid treatment.
  • the artlficial threads are assed through one or more thread guides w ile be1n sub-- jected to an acid treatment in troug s or channel-shaped members,-the pos1t1on of the guides being adjustable in the said troughs or members.
  • the guides lift the threads from the bottom of the trough or channel-shaped member.
  • these thread guides may be employed and they are preferably made of acid resisting material, for example acid resisting steel, and may be made'out of wire or strip material.
  • Figure 1 shows in lon ltucunal section an acid treatment channel s aped member with a thread guide
  • Figure 2 is a plan of Figured
  • Figure 3 is a side view ot F gure 1; Figure 4 shows the thread guide to a larger scale.
  • a thread a is shown as being delivered from a suitable spinni mechanism and passing around a gulde r b to a channelled member suggested to carry-out the acid treatment by c.
  • The"threads are in known manner subjected to an acid treatment'in the channeled member,
  • a thread guide d fits over the walls of the channeled member and .has a central portion which projects into the channeled member and into close proximity with the I bottom thereof in order to lift the thread more or 1cm from the bottom.
  • This depending por- 7 tion is substantially V-shaped, the point-of the V, however, being rounded off.
  • the thread'guide is shown as being made of wire bent into a shape so that it can be placed accurately in position and'retained firmly over the channelled member.
  • the simple form of thread guide permits its use with acid treatment apparatus already in use and the thread guide may be disposed atany desired position in the apparatus in a perfectly simple manner.
  • This atter feature is of importance as it has been found that the particular position of the thread guide affects the grain or structure of the artlficialthreads, soft or hard artificial threads in fact being obtained as desired according as to whether the thread guide is disroduce'the results which can be 'ob-' were actually being sub'ected to the acid treatment As a matter 0 fact, the slits owing to them threads efore and after the acidtreatment.
  • the thread guides employed according to the presentinvention can be secured convenientl and firmly to the channelled member and 0 not affect the flow of the acid through the channelled member and. the threads obtained are free from irregularities and are of absolute uniform quality.
  • a process for the production of artificial threads by the cupro-ammonium stretch spinning process consisting in conducting the threads through a thread guide adjustablymounted in a channelled member and the said threads simultaneously ⁇ )0 an aci treatment in said channelled mem- 4.
