Definitions
- the object of the present invention is a method of production of a more flexible and less brittle artificial silk, especially prepared to protect the silk against damage in working.
- the process includes the following treatment.
- the artificial silk is spun and is then wound upon bobbins or the like or into centrifugals and, after being washed, but before further working, undergoes a treatment with oils, soap solution or similar suitable mate'- ria s.
- the filaments are soft and somewhat gelatinous, and even the first chemical action is quite incomplete. It appears that the filament may (at this stage) consist of a casing of precipitated cellulose hydrate inclosing a core of unreacted viscose, and it is further well known that the filaments a very slight strength at this stage, they are not brittle and do not break from bending.
- the filaments are much harder and after drying (even incomplete drying) they are quite brittle.
- the present invention aims at somethlng quite different. It will protect the artificial silk filaments spun onthe bobbins or the like, immediately after it has been spun and the chemicals sticking to it cleared oil", 1. e., before it undergoes further manipulations in the manufacturing of artificial silk yarn, as for instance twisting, winding, etc., (herein referred to as mechanical treatment) against possible damages occurring in the course of the aforesaid steps, as well as in the fabricatingoperations and further working.
- This is suitably done by treating the silk filaments, for example on said bobbins, with oil or an emulsion of oil or oil solution or soap solution and the like means for the purpose, such treatment being referred to generically as oiling the filaments.
- the artificial silk thread becomes soft and flexible, and capable of withstanding the possibilities of breaking and similar damage in the course of further treatment such as mechanical treatment and fabricatingoperations. Ithasbeendemonstrated by tests that artificial silk treated accordin to this invention, and similar artificial. sil that has not undergone this treatment, showed a considerable diflerence in the per centage of salable products. While the silk treated according to the stated invention shows practically no breaking of the capillary threads (filaments) there appears a considerable amount of such capillary breaks in the silk that had not undegone this treat- 95 ment. The finer the count of the various capillary threads, the more conspicuous is this difference, whereas with the heavier counts it is less noticeable. The working of this method in actual prac- 100 tice may for instance,
- soap solutions and oil emulsions as referred to may be generically included in the expression aqueous vehicle carrying an oily material, all as a freely liquid mixture.
- the lubricating (softening) liquid can also for instance be discharged by pressure through the layers of the threads from the inside to the outside of the perforated bobbins or the cakes while in the centrifugals.
- the bobbins with the washed and if required or the so treated cakes may also be immersed in the lubricating liquid or the lubricating liquid may e sprayed on them.
