preparation example Construction

[0041] The preparation methods of the dibenzyl ether described in the present invention are those well known to those skilled in the art. Specific preparation methods can be listed, for example: it is prepared by the action of benzyl chloride and concentrated alkali, which is also a by-product during the production of benzyl alcohol, and it can also be prepared from benzyl alcohol through etherification.

[0042]Dibenzyl ether often contains impurities such as benzaldehyde and toluene. Its purification method includes, for example, sufficient washing with sodium hydroxide solution and sodium bisulfite solution to remove benzaldehyde. After drying over potassium carbonate, toluene was removed by fractional distillation under reduced pressure. Distillation is carried out in a nitrogen or carbon dioxide stream. It can also be refined by crystallization.

[0043] Based on 100 parts by weight of the nonionic surfactant, the dibenzyl ether is 1-10 parts.

Abstract

The invention provides a novel high-performance dyeing carrier composition which is prepared from the following ingredients in parts by weight: 100 parts of a non-ionic surface active agent and 1-10 parts of benzyl ether, wherein the non-ionic surface active agent at least comprises fatty alcohol ether, polyethylene glycol fatty ester and styryl-phenol polyethenoxy ether.

Description

technical field [0001] The invention relates to the field of textile printing and dyeing auxiliaries, in particular to a novel high-performance dye-conducting agent composition. Background technique [0002] Polyester is an important variety of synthetic fibers and is the trade name of polyester fibers in my country. It is a fiber-forming high polymer prepared from terephthalic acid (PTA) or dimethyl terephthalate (DMT) and ethylene glycol (EG) through esterification or transesterification and polycondensation reactions—— Polyethylene terephthalate (PET), a fiber made by spinning and post-processing. [0003] From the perspective of polyester molecular composition, it is composed of short aliphatic hydrocarbon chains, ester groups, benzene rings, and terminal alcohol hydroxyl groups. In addition to the existence of two terminal alcohol hydroxyl groups in polyester seeds, there are no other polar groups, so the hydrophilicity of polyester fibers is extremely poor. Polyeste...
