6 tlliairns. ((11. 106-165) The invention relates to the manufacture of shaped articles from viscose, and more particularly, regenerated cellulose filaments with a thick skin or consisting of skin. It is known that high-strength rayon yarns having addi tional excellent properties, which make them suitable, for instance, for the use in automobile tires, are obtained when the yarn consists of more than 50% skin.
High-strength regenerated cellulose filaments of this type are usually obtained by extruding viscose into an aqueous sulfuric acid coagulating bath containing at least about 2% of zinc sulfate. Various additives, to be added to the viscose and/or to the spinning bath in critical amounts have been suggested to obtain thick-skinned or all-skin regenerated cellulose filaments or other shaped articles.
It is the object of the present invention to provide additives of this type which are fully reliable and which guar antee a flaw-less spinning process.
In accordance with this invention, this is accomplished by extruding the viscose into a sulfuric acid coagulating bath in the presence of at least 0.5 preferably about 1%, based on the weight of the cellulose, of a polyepoxyethane substituted fatty acid amide selected from the group consisting of cocoamide, hydrogenated tallow amide and red oil amide with the formula:
(CZILOMH wherein x+y= 5 to 30, and R is the fatty alkyl group.
The invention will be elucidated in the following examples, in which the following substances were tested:
Ethomid C/ Derived from cocoamide, x+y= 5 Ethomid C/: Derived from cocoamide, x|y=10 Ethomid C/ Derived from cocoamide, x+y=15 Ethomids are surface active agents.
Example 1 A viscose with 7% of cellulose and 6% of NaOH was extruded at an ammonium chloride number of 11.8 into a spinning bath with 9% H 18% of Na SO and 7% ZnSO at a temperature of C. The filaments emerging from this spinning bath were guided through a bath with 1% of H with a temperature of C., in which bath the filaments were stretched 85%.
In the presence of 0.5%, 1.0% and 2.0%, respectively, of Ethomid C/ 15 in the viscose, calculated on the cellulose, filaments were obtained the cross sections of which Patented Jan. 9, 1962 consisted of skin. This was concluded after dyeing the filaments according to the selective dyeing method Example 2 The experiments mentioned in Example 1 were repeated with the difference that Ethomid C/20 was added. In respect of the cross section of the thread, as well as the respect of the non-occurrence of thread breakages, the same results were found as in Example 1.
, Example 3 The experiments mentioned in Example 1 were repeated with the difference that Ethomid C/ 25 was added. respect of the cross section of the thread, as well as in respect of the non-occurrence of thread breakages, the same results were found as in Example 1.
This is a division of application Serial No. 584,147, filed May 10, 1956, now abandoned, of which I was a joint inventor.
What I claim is:
1. The method of producing shaped bodies with a thick skin from viscose, comprising the step of extruding the viscose into a sulfuric acid coagulating bath containing at least 2% zinc sulfate in the presence of between 0.5% and about 2%, based on the Weight of the cellulose, of a polyepoxyethane substituted fatty acid amide selected from the group consisting of cocoamide, hydrogenated tallow amide and red oil amide with the formula:
(CZH4O)XH RCN ll z 4 )y 0 wherein x+y=5 to 30, and R is the fatty alkyl group of said amides.
2. The method of claim 1, wherein the fatty acid amide is cocoamide.
3. The method of claim 2,
4. The method of claim 2,
5. The method of claim 2,
6. The method of claim 5,
wherein x+y=5.
wherein x+y=10. wherein x+y=15. wherein about 1% of said fatty acid amide is present in the viscose.
