Beim Färben nach Kontinueverfahren beträgt der Flottenauftrag zweckmässig 40-700, vorzugsweise 40-500 Gew.-%, wobei sich ein Dämpfprozess, z.B. bei 100°C während 5 Minuten anschliesst.When dyeing according to the continuous process, the liquor order is expediently 40-700, preferably 40-500% by weight, followed by a steaming process, for example at 100 ° C. for 5 minutes.
Nach Beendigung des Färbeprozesses werden die hergestellten Färbungen auf übliche Weise gewaschen und getrocknet.After the dyeing process has ended, the dyeings produced are washed and dried in the customary manner.
Man erhält nach der vorliegenden Erfindung Färbungen mit guter thermischer und/oder photochemischer Stabilität.According to the present invention, dyeings with good thermal and / or photochemical stability are obtained.
Als die erfindungsgemäss zu stabilisierenden Färbungen kommen solche in Betracht, die durch Säurefarbstoffe und kationische Farbstoffe, besonders Azo- und Anthrachinonfarbstoffe erzeugt werden.The dyeings to be stabilized according to the invention are those which are produced by acid dyes and cationic dyes, in particular azo and anthraquinone dyes.
Unter Polyamidfasermaterial wird in dem erfindungsgemässen Verfahren ein Gemisch synthetischer Polyamidfasermaterialien, insbesondere Polyamid-6 bzw. Polyamid 66 in Mischung mit sauer modifiziertem Polyamidfasermaterial, d.h. basisch anfärbbares Polyamid verstanden. Grundsätzlich kann das Polyamidmaterial in den verschiedensten Verarbeitungsformen vorliegen, wie z.B. als Faser, Garn, Gewebe, Gewirke, Vlies oder Flormaterial. Bevorzugt sind Polyamidteppiche. Das Polyamidfasermaterial aus regulärem und sauer modifiziertem Polyamid kann in jedem gewünschten Mischungsverhältnis vorliegen. Bevorzugt sind Mischungen dieser Polyamidfasermaterialien im Verhältnis 10:1 bis 1:10, insbesondere 25:75 bis 75:25 und vorteilhaft 40:60 bis 60:40.In the process according to the invention, polyamide fiber material is a mixture of synthetic polyamide fiber materials, in particular polyamide-6 or polyamide 66 in a mixture with acid-modified polyamide fiber material, i.e. understood basic dyeable polyamide. In principle, the polyamide material can be in a wide variety of processing forms, e.g. as fiber, yarn, fabric, knitted fabric, fleece or pile material. Polyamide carpets are preferred. The polyamide fiber material made from regular and acid-modified polyamide can be present in any desired mixing ratio. Mixtures of these polyamide fiber materials in a ratio of 10: 1 to 1:10, in particular 25:75 to 75:25 and advantageously 40:60 to 60:40, are preferred.
Die folgenden Beispiele veranschaulichen die Erfindung. Teile bedeuten Gewichtsteile und Prozente Gewichtsprozente. Temperaturen sind in Celsiusgraden angegeben. Die angegebenen Gewichtsprozente beziehen sich auf das eingesetzte Fasergewicht.The following examples illustrate the invention. Parts mean parts by weight and percentages percentages by weight. Temperatures are given in degrees Celsius. The percentages by weight refer to the fiber weight used.
Es werden 2 Muster zu je 20g eines vorgewaschenen Polyamidteppichs vorbereitet; der Pol hat ein Gewicht von 500 g/qm und besteht zu 50 Gew.-% aus regulär färbbarem Polyamidfasermaterial und zu 50 Gew.-% aus basisch färbbarem Polyamidfasermaterial von 1300 dtex. Diese Muster werden in Bomben [z.B. in einem Labomat® der Firma Mathis, Niederhasli, Schweiz] gefärbt, wobei das Flottenverhältnis 1:25 beträgt. Für beide Färbungen wird zunächst eine Flotte folgender Zusammensetzung zubereitet:
- 1g/l des Färbereihilfsmittels der Formel
- 0,05 Gew.-% einer 1:1-Mischung aus den Farbstoffen der Formeln
- 0,15 Gew.-% des Farbstoffes der Formel
- 0,04Gew.-% des Farbstoffes der Formel
- 0,05 Gew.-% des Farbstoffes der Formel
- und 0,15 Gew.-% der 3:1-Farbstoffmischung aus den Farbstoffen der Formeln
- 1g / l of dyeing aid of the formula
- 0.05% by weight of a 1: 1 mixture of the dyes of the formulas
- 0.15% by weight of the dye of the formula
- 0.04% by weight of the dye of the formula
- 0.05% by weight of the dye of the formula
- and 0.15% by weight of the 3: 1 dye mixture from the dyes of the formulas
Die Färbeflotte wird halbiert. Die Flotte 1 bleibt unverändert, Flotte 2 wird dagegen mit 0,5 g/l Mangan(II)acetat versetzt.The dye liquor is halved. Fleet 1 remains unchanged, while fleet 2 is mixed with 0.5 g / l manganese (II) acetate.
Die Teppichmuster werden in die auf 40°C erwärmten Flotten gegeben und mit dem Färben begonnen. Zunächst wird mit 2°C/Minute auf 95°C aufgeheizt, dann 60 Minuten bei dieser Temperatur gefärbt, schliesslich abgekühlt, kalt gespült, zentrifugiert und bei 100°C getrocknet.The carpet samples are placed in the liquors heated to 40 ° C. and dyeing is started. The mixture is first heated to 95 ° C. at 2 ° C./minute, then colored for 60 minutes at this temperature, finally cooled, rinsed cold, centrifuged and dried at 100 ° C.
Man erhält einen Teppich mit einer Orange/Blau-Musterung. Die Trennung der beiden Farben ist auf beiden Mustern ausgezeichnet.A carpet with an orange / blue pattern is obtained. The separation of the two colors is excellent on both patterns.
Die Ermittlung der Lichtechtheit der beiden Muster erfolgt nach ISO-Norm 105-B02 und AATCC 16E. Es werden folgende Ergebnisse erhalten:
Die Lichtechtheitsnoten gemäss ISO 105-B02 werden mit dem Blaumassstab und die Lichtechtheitsnoten gemäss AATCC 16E werden mit dem Graumassstab ermittelt.The light fastness grades according to ISO 105-B02 are determined using the blue scale and the light fastness grades according to AATCC 16E are determined using the gray scale.
Aus den belichteten Mustern ist zu ersehen, dass die Verbesserung der Lichtechtheit besonders den basisch anfärbbaren Teil betrifft, da dieser vom Farbton her (orange) das Dessin dominiert.From the exposed patterns it can be seen that the improvement in light fastness particularly affects the basic part that can be dyed because this (orange) dominates the design.
Durch den Zusatz von Mn(II)-Ionen wird eine Verbesserung der Lichtechtheit erzielt.The addition of Mn (II) ions improves the lightfastness.
Man bereitet 20 g eines vorgewaschenen Polyamidteppichs, dessen Flor aus mit basischen und sauren Farbstoffen anfärbbaren Fasern im Verhältnis 1:1 besteht. Man färbt wie in Beispiel 1 angegeben, verwendet jedoch die folgende Farbstoff-Kombination:
- 0,002 Gew.-% der 1:1-Farbstoffmischung der Farbstoffe der Formeln (101) und (102),
- 0,01 Gew.-% des Farbstoffes der Formel (103),
- 0,04 Gew.-% des Farbstoffes der Formel
- 0,22 Gew.-% des Farbstoffes der Formel (104),
- 0,18 Gew.-% des Farbstoffes der Formel (105), und
- 0.26 Gew.-% der 3:1-Farbstoffmischung der Farbstoffe der Formeln (106) und (107).
- 0.002% by weight of the 1: 1 dye mixture of the dyes of the formulas (101) and (102),
- 0.01% by weight of the dye of the formula (103),
- 0.04% by weight of the dye of the formula
- 0.22% by weight of the dye of the formula (104),
- 0.18% by weight of the dye of the formula (105), and
- 0.26% by weight of the 3: 1 dye mixture of the dyes of the formulas (106) and (107).
Das Färbebad 3 verbleibt analog Färbebad 1 ohne Zusatz von Mn(II)-Ionen, während dem Färbebad 4 3 Gew.-% der folgenden Verbindung zugesetzt werden: Mn(II)-Komplex des Tetranatriumsalzes der Äthylendiamintetraessigsäure.The dyebath 3 remains analogous to dyebath 1 without the addition of Mn (II) ions, while 3% by weight of the following compound is added to the dyebath 4: Mn (II) complex of the tetrasodium salt of ethylenediaminetetraacetic acid.
Die Fertigstellung und Trocknung der Färbung erfolgt wie in Beispiel 1 angegeben.The dyeing is completed and dried as described in Example 1.
Die Ermittlung der Lichtechtheit der beiden Muster erfolgt nach ISO-Norm 105-B02 und AATCC 16E. Es werden folgende Ergebnisse erhalten:
Die Lichtechtheitsnoten gemäss ISO 105-B02 werden mit dem Blaumassstab und die Lichtechtheitsnoten gemäss AATCC 16E werden mit dem Graumassstab ermittelt.The light fastness grades according to ISO 105-B02 are determined using the blue scale and the light fastness grades according to AATCC 16E are determined using the gray scale.
Aus den belichteten Mustern ist zu ersehen, dass sich die Verbesserung ausschliesslich auf den basisch anfärbbaren Anteil bezieht.From the exposed patterns it can be seen that the improvement relates exclusively to the basic colorable portion.
Wenn man wie in den Beispielen 1 und 2 angegeben verfährt und anstelle der dort angegebenen Farbstoffe solche der folgenden Formeln verwendet, erhält man ebenfalls Färbungen mit verbesserter Lichtechtheit:
