Verfahren zum Spinnfärben von Polyacrylnitril bekannt·Process for spin dyeing polyacrylonitrile known·

Ea ist weiterhin bekannt, Polyaorylaitrilfasera naoh dem Erspinnen im getfeuohten Zustand (Gelfärbung) im wäßrigen Medium zu färben· Außerdem ist ee aus der textlien Veredlung bekannt, fertige Erzeugnisse aus Polyaorylnltrilfaserm im wäßrigen Medium zu färben« Das letzte Färbeverfahren muß mindestens bei oder über 1oo 0G erfolgen·Ea is also known Polyaorylaitrilfasera naoh the spinning in getfeuohten state (gel staining) to dye in an aqueous medium · In addition ee is known from text lien finishing, dyeing finished goods from Polyaorylnltrilfaserm in an aqueous medium "The last dyeing process must at least or more than 1oo 0 G take place

Für die Spinnfärbung sind speziell aufbereitete und teurt Farbstoffe erforderlich. Die Gelfärbung im wäßrigen.Medium.steilt einen aufwendigen Färbeprozeß dar, für den ebenfalls eine spezielle Farbstoffaus»· wahl erforderlich ist« Die bekannten Färbeverfahren in der Textilveredlung sind duroh einen hohen zeitlichen, energetischen und apparativen .Aufwand gekennzeichnet·Specially prepared and expensive dyes are required for spin dyeing. The gel staining in the aqueous medium divides an expensive dyeing process for which a special dye composition »· choice is required «The known dyeing processes in textile finishing are due to a high time, energetic and equipment expenditure marked

Zweck der Erfindung ist es, ein Verfahren zum Färben von Polyaorylnitrilfasern zu schaffen, welohea dia angeführten Nachteile beseitigt·The purpose of the invention is to provide a method of dyeing of polyaoryl nitrile fibers, which eliminates the disadvantages mentioned

Der Erfindung liegt die Aufgabe zugrunde, eine solche Färbeteehnologie zu entwickeln, die eine kurzzeitige Färbung von Polyaorylnitrilfaserstoffen mit guter Farbechtheit gewährleistet«The invention is based on the object of such To develop dyeing technology, which is a short-term dyeing of Polyaorylnitrilfaserstoffe with good Color fastness guaranteed "

Erfindungsgemäß wird der Farbstoff in einem organischen lösungsmittel oder in einem Gemisch von mehre*-» ren organischen Lösungsmitteln gelöst und bei Temperaturen unterhalb des Siedepunktes des Färbemediums According to the invention, the dye is used in an organic solvent or in a mixture of several * - » Ren organic solvents and dissolved at temperatures below the boiling point of the dyeing medium

Es ist zwar bereits bekannt, Polyesterfaserstoffe im niohtwäßrigen Medium zu färben. Danaoh wird der Farbstoff in einem Quellmittel für Polyesterfaserstoffe gelöst und unter entsprechenden Bedingungen die Färbung durchgeführt« Es war aber überraschend, daß dieses bekannte Färbeprinzip für das Färben von Polyaoryl-Although it is already known to use polyester fibers in the To stain non-aqueous medium. Danaoh the dye is dissolved in a swelling agent for polyester fibers and the dyeing is done under the appropriate conditions carried out "It was surprising, however, that this well-known dyeing principle for the dyeing of polyaoryl

nltrilfaserstoffen unter Verwendung von Farbstoffen der verschiedenen Farbstoffklassen geeignet ist» Der Faohmann konnte nioht vermuten und erwarten, daß eine Anwendbarkeit auf Polyaorylnitrilfaserstoffe gegeben 1st, da die für die Lösungsmittelfärbung von Polyestexfaserstoffen vorgeschlagenen organischen lösungsmittel eine äußerst geringe Quellung bei Polyaorylnitrilfaserstoffen bewirken und demzufolge angenommen werdenmußte, daß die Übertragung dieses Färbeprinzipes zu keinen günstigeren Färbebedingungen bezüglich des Energie- und Zeitaufwands gegenüber den herkömmlichen Verfahren der Färbung im wäßrigenNon-woven fabrics using dyes suitable for the various classes of dyestuffs an applicability to poly (aorylnitrile) fibers is given, since they are used for the solvent dyeing of Polyester fibers proposed organic Solvents cause an extremely low swelling of polyaryl nitrile fibers and consequently it had to be assumed that the transfer of this dyeing principle to no more favorable dyeing conditions in terms of energy and time compared to the conventional methods of dyeing in aqueous
