Description

United States Patent 2 Claims. in. 260-41) This application is a cont-inuation-in-part of US. application Serial No. 601,121, filed July 31, 1956, now ab an doned.
The invention relates to spin-dyed polyacrylonitrile filaments and to a process of producing the same. More particularly the process consists in dissolving in the spinning solution to be used for the production of polyacrylonitrile filaments a nigrosine base and spinning the solution by conventional methods.
Nigrosine bases to be used in the present process are known under the classical name Nigrosine Spirit Soluble (Colour Index, 2nd Edition, vol. 3, No. 50415 and Farbstofitabellen by Schultz, 7th Edition, page 427) and are preferably produced by heating an arylamine such as aniline, aniline salts, and nitroor nitroso benzene in the presence of iron and/or iron salts at about 180 to 200 C. They are of more or less indefinite structure.
The process is advantageously carried out by dissolving the afore-mentioned nigrosine bases into the vinyl polymer in dissolved state. The dyestuffs are preferably dissolved in the organic solvent commonly used for spinning of the polyacrylonitrile, such as in dimetlhyl formamide. The solution thus obtained is then mixed with the solution of the acrylonitrile polymer and then worked up into shaped articles, particularly into filaments and fibres respectively.
The new process leads to dark spin-dyed polyacrylonitrile fibres which exhibit excellent fastness properties,
3,232,904 Patented Feb. 1, 1966 especially very good fastness to light and to rubbing. This result is most surprising because nigrosine bases dye polyacrylon-itrile shaped articles, such as fibres and filaments, only poor shades when applied from an aqueous dye-bath.
Example 15 kilograms of polyacrylonitrile and 0.150 kilogram of Nigrosine Spirit Soluble (Colour Index, 2nd Edition, No. 50415) are dissolved in kilograms of dimethylformamide and the solution is then spun in conventional manner. A deep black spin-dyed fabric is thus obtained which exhibits excellent fastness proper-ties.
We claim:
1. A process for the manufacture of spin-dyed polyacrylonitrile filaments which comprises dissolving in the spinning solution to be used for the production of polyacrylonitrile filaments a nigrosine spirit soluble dyestuff and spinning the solution.
2. Spin-dyed polyacrylonitrile filaments obtained according to the process of claim 1.
