DYEING EXAMPLE A
20 parts of the dyestuff described in Example 1A and 80 parts of dextrin are ground for 4 hours in a powder mill. The same dyestuff mixture may also be obtained by making a paste with 100 parts of water and subsequently spray-drying it. 1 part of the preparation thus obtained is made into a paste with 1 part of 40% acetic acid, the paste is covered with 200 parts of demineralised water and boiled for a short time. This is then diluted with 7000 parts of demineralised water, then 2 parts of glacial acetic acid are added, and it is entered into a dyebath at 60.degree. together with 100 parts of polyacrylonitrile fabric. The material may already be pretreated for 10-15 minutes at 60.degree. in a bath consisting of 8000 parts of water and 2 parts of glacial acetic acid.
The bath is heated over the course of 30 minutes to 98.degree.-100.degree., boiled for 11/2 hours and the fabric then removed and rinsed. A yellow dyeing is obtained, with good light and wet fastness properties.
10 parts of the dyestuff given in Example 1 may also be dissolved in 60 parts of glacial acetic acid and 30 parts of water. A stable, concentrated solution of the dyestuff is obtained, with a dyestuff content of about 10%, which may be used as in the above dyeing formula for dyeing polyacrylonitrile.
DYEING EXAMPLE B
20 parts of the dyestuff of Example 1A are mixed for 48 hours in a ball mill with 80 parts of dextrin; 1 part of the preparation thus obtained is made into a paste with 1 part of 40% acetic acid, the paste is covered with 200 parts of demineralised water and boiled for a short time. Dyeing takes place as follows using this stock solution:
(a) The stock solution is diluted with 7000 parts of demineralised water, then 21 parts of calcined sodium sulphate, 14 parts of ammonium sulphate, 14 parts of formic acid and 15 parts of a carrier based on reaction products of ethylene oxide with dichlorophenols are added, and it is entered with a dyebath at 60.degree., together with 100 parts of acid modified polyester fabric. The material may already be pretreated for 10-15 minutes at 60.degree. in a bath consisting of 8000 parts of water and 2 parts of glacial acetic acid.
The bath is heated over the course of 30 minutes to 98.degree.-100.degree., boiled for one hour and the substrate then removed and rinsed. An even yellow dyeing with good wet fastness is obtained.
(b) The stock is diluted with 3000 parts of demineralised water, then 18 parts of calcined sodium sulphate and 6 parts each of ammonium sulphate and formic acid are added, and it is entered into a dyebath at 60.degree., together with 100 parts of acid modified polyester fabric. The bath is a closed system and is heated over the course of 45 minutes to 110.degree., this temperature is maintained for 1 hour with shaking, then it is cooled over the course of 25 minutes to 60.degree., and the fabric removed and rinsed. An even yellow dyeing with good wet fastness is obtained.
(c) The process is as in (b), but the closed vessel is heated for 1 hour at 120.degree..
DYEING EXAMPLE C
20 parts of the dyestuff of Example 1A are mixed for 48 hours in a ball mill with 80 parts of dextrin.
1 part of the preparation thus obtained is made into a paste with 1 part of 40% acetic acid, the paste is covered with 200 parts of demineralised water and boiled for a short time. This solution is added to the dye bath which is prepared as follows:
The solution is diluted with 700 parts of demineralised water, then 21 parts of calcined sodium sulphate, 14 parts of ammonium sulphate, 14 parts of formic acid and 15 parts of a carrier based on reaction products of ethylene oxide with dichlorophenols are added, and the liquor is buffered with an acid buffering solution to give a pH of 6, and this is then entered at 25.degree. with 100 parts of acid modified polyamide fabric which is modified by acid groups into the dyeing vessel, at a liquor ratio of 1:80. The bath is heated over the course of 45 minutes to 98.degree., boiled for one hour and the fabric then rinsed under running water at 70.degree.-80.degree., and subsequently under cold water. The fabric may be centrifuged so as to dry it, and then ironed.
A yellow dyeing with good fastness properties is obtained.
