Description
Patented Feb. 11, 1936 CELLULOSIC SPINNING SOLUTIONS CON- TAINING AROMATIC SILICON DERIVA- TIVES Rudolph S. Bley, Elizabethton, Tenn., assig'nor to North American Rayon Corporation, New York, N. Y., a corporation of Delaware N Drawing.
10 Claims.
The present invention relates to a process of preparing cellulosic spinning solutions from which soft-lustre products, such as filaments,
yarns, ribbons, films, etc., may be produced. The primary object of my invention has to do with the incorporation of aromatic silicon derivatives into cellulosic spinning solutions, which will yield, upon extrusion or molding, soft-lustre products of pleasing hand.
Another object of my invention has to do with the admixture of phenyl-silicon derivatives with viscose and cuprammonium cellulose solutions.
A third object of the present invention has to do with the incorporation of tolyl-silicon derivatives into viscose and cuprammonium cellulose solutions.
A fourth object of this invention has to do with the incorporation of benzyl-silicon derivatives into the aforementioned cellulosic solutions.
A fifth object of this invention relates to the manufacture of novel, soft-lustre products per se containing aromatic silicon derivatives.
Other objects of my invention will become apparent to those skilled in the art after a study of the following specification.
In the early days of rayon manufacture, the demand was entirely for yarns having the highest degree of lustre. Later, when it was found that highly lustrous rayon too clearly indicated its origin-an artificial fibre-a demand arose for artificial silk which more closely approximated to natural silk. The earliest attempt to meet the demand of dull-lustre viscose, for example, was a method of retaining sulphur particles in the 35 fibres by discontinuing the normal desulphurizing step during its manufacture. Although this yarn showed decreased lustre, due to scattering of light by the sulphur particles, it was impermanent and exhibited an unattractive "bloom. has been improved by dispersing, instead of sulphur, fine inorganic or organic particles and globules in cellulosic spinning solutions, for example, pigments, hydrocarbons; oils, etc. When inorganic compounds, such as titanium dioxide, silica, etc., are dispered in cellulosic spinning solutions, they tend to cut the thread guides through which they are led during the extrusion process, and in addition, they weaken the cellulosic yarns. Hydrocarbons, emulsified with spinning solutions to deluster cellulosic products obtained therefrom, have the great disadvantage of being inflammable, while vegetable oils become rancid and form skin-irritating acids. 1
I have, unexpectedly, found, that aromatic silicon derivatives possess properties which render This method Application October 22, 1934, Serial No. 749,486
them especially suitable as delustering agents for rayon products, since they are practically fire-resistant and do not form irritating decomposition products. The following table depicts a number of such derivatives of silicon which may be used in combination with viscose and cuprammonium cellulose solutions.
Phenylsilicon triethyl-ether (CizHzosiOa) Silico-benzoic acid (CsH5.Si(OC2H5) 3) Triethyl-phenyl silicon (CeH5.Si(C2H5) 3) Triethyl-phenyl-silicon chloride (C12H10C12Si) Silicon-triphenyl chloride (CiaH15SiC1) Silicon tetraphenyl (C24H20Si) Trisilico-benzoyl-silicic acid (C1sH1aSi4O'z) Silico-tetranitro-tetraphenyl (C24H1sN4SiOa) Silico-di-o-diphenylene (C12H8Si) Silicon tetrabenzyl (CzaHzsSi) P-silicotolyl chloride (C'lH'lSiClIi) Silicotolyl acid (C7HsSiO2) Silicon tetratolyl (CzsHzaSi) and other carbo-and heterocyclic silicon compounds.
Ill.
, Example About 1 to 20% of an aromatic silicon derivative, for example, triethyl-phenyl silicon, is dispersed in and/or emulsified with a cellulosic spinning solution, such as viscose and cuprammonium cellulose, the aforementioned percentages being based upon the cellulose content of the solution. After uniformly distributing the delustering agent in the spinning solution, it is extruded through suitable spinning nozzles into a conventional spinning bath. Organic solvents, 3a inorganic or organic pigments, etc., may be added to the spinning solutions in addition to the silicon compounds. The amounts of these aromatic silicon derivatives, to be added to the cellulosic solutions, may be varied at will. In this manner, more or less delustered rayon products may be obtained.
Modifications of my process will readily be recognized by those skilled in the art, and I desire to include all those modifications falling within the scope of the appended claims. In these claims, the term aromatic silicon compound is limited to such compounds which are substantially water-insoluble and resistant to attack by acids and alkalis of such concentrations convntionally used in the rayon art.
I claim:
1. A spinning solution for the manufacture of soft-lustre products comprising a solution of the group consisting of viscose and cuprammonium cellulose together with a phenyl-silicon derivative, said derivative being stable in said spinning solution.
2. A spinning solution for the manufacture of soft-lustre products comprising a solution of the group consisting of viscose and cuprammonium cellulose and a triethyl-phenyl silicon, said triethyl-phenyl silicon being stable in said spinning solution.
3. As a new article of manufacture, regenerated cellulose containing a finely dispersed. phenyl derivative of silicon.
4. As a new article of manufacture, regenerated cellulose containing a small amount of a triethyl-phenyl silicon.
5. A spinning solution for the manufacture of soft-lustre products comprising a solution of the group consisting of viscose and cuprammonium cellulose together with a substance of the group consisting of phenyl-silicon derivatives, tolylsilicon derivatives and benzyl-silicon derivatives, said substance being stable in said solution.
6. A spinning solution for the manufacture of soft-lustre products comprising a solution of the group consisting of viscose and cuprammonium cellulose together with a benzyl-silicon derivative, said derivative being stable in said solution.
7. A spirming solution for the manufacture of 5 soft-lustre products comprising a solution of the group consisting of viscose and cuprammonium cellulose together with a tolyl-silicon derivative, said derivative being stable in said solution.
8. As a new article of manufacture, regenerated 1 cellulose containing a substance of the group consisting of phenyl-silicon derivatives, tolyl-silicon derivatives and benzyl-silicon derivatives, said substance being finely dispersed throughout said cellulose. 15
9. As a new article of manufacture. regenerated cellulose containing a finely dispersed tolyl-silicon derivative.
10. As a new article of manufacture, regenerated cellulose containing a finely dispersed benzyl- 20 silicon derivative.
