Abstract
The invention discloses an amino naphthol type disazo heterocyclic disperse dye, and belongs to the technical field of fine chemical engineering. Firstly, preparing heterocyclic aromatic amine diazonium salt by using heterocyclic aromatic amine derivative as diazonium component, and carrying out coupling reaction with amino naphthol compound under acidic condition to prepare amino naphthol type monoazo heterocyclic disperse dye; and then the prepared monoazo heterocyclic disperse dye is used as a coupling component, and is subjected to coupling reaction with another part of diazonium salt under alkaline conditions to prepare the amino naphthol type bisazo heterocyclic disperse dye. The amino naphthol type disazo heterocyclic disperse dye can be used under the condition of 0.5-5g/L NaOH, has better color fastness, and can realize the short-process dyeing and finishing processing of terylene and blended fabrics thereof.
Description
Technical Field
The invention belongs to the technical field of fine chemical engineering, and particularly relates to an amino naphthol type disazo heterocyclic disperse dye.
Background
The current situation of high water consumption, high energy consumption and high pollution discharge of textile printing and dyeing is an important subject to be solved currently. Polyester fiber is widely applied to clothing, home textiles, military special fabrics and industrial textiles due to the excellent physical and chemical properties, and becomes the synthetic fiber variety with the largest yield and the most wide application in the world at present.
However, in dyeing and finishing of terylene and blended fabrics thereof, the pretreatment of fabrics (including desizing, scouring, alkali reduction and other procedures) and the reduction and cleaning after dyeing are all carried out under alkaline conditions, especially the scouring and alkali reduction are all carried out under strong alkaline (NaOH) conditions, and the disperse dye dyeing in the middle link is an acid bath (ph=4-4.5). The whole dyeing process has repeated neutralization and washing, long process flow and high energy and water consumption. The disperse dye dyed under the strong alkaline condition is developed, the pretreatment and the dyeing of the polyester fabric can be carried out in the same bath, and the method has the advantages of remarkable energy conservation and emission reduction.
The conventional disperse dye is not alkali-proof, and partial disperse dye has certain stability under certain alkaline conditions. The existing method mainly adopts alkaline agents such as sodium carbonate, sodium phosphate, sodium dihydrogen phosphate, disodium hydrogen phosphate and the like, and has weak alkalinity. However, the alkaline agent adopted in the pretreatment of terylene and blended fabrics thereof is NaOH and has higher concentration. Therefore, development of disperse dyes capable of stably dyeing under NaOH conditions has a large application market.
