Abstract

The invention provides an expanding dyeing accelerant and a preparation method thereof. The expanding dyeing accelerant contains the following raw materials in parts by mass: 55-75 parts of polyol disalicylate, 10-25 parts of dialkyl maleate, 5-20 parts of cardanol polyoxyethylene ether and 5-20 parts of polyoxyethylene oleate. The expanding dyeing accelerant provided by the invention is green andfriendly to environment; the expanding dyeing accelerant is suitable for disperse dyeing of polyester fiber and blended fabrics thereof, yarn and velvet under low temperature conditions; the expanding dyeing accelerant can promote plasticization and expansion of the polyester fiber in a dyeing liquid and has the ability of solubilizing, dispersing and transferring disperse dyes to ensure that thedyes are easier to diffuse and migrate from the dye liquid to the interior of the fiber and the generation of colored spots can be avoided at the same time; and therefore, the low-temperature dyeingcan be realized in a real sense.

Description

technical field [0001] The invention relates to an auxiliary agent used in the textile dyeing and finishing industry, in particular, a bulking dye accelerator, which can be specially used for low-temperature dyeing of polyester. Background technique [0002] It is known that polyester, commonly known as "Dacron", is the simplest one among the three major synthetic fibers, and the price is relatively cheap. It has a wide range of uses and is widely used in the manufacture of clothing fabrics and industrial products. In addition, it has the characteristics of strong and durable, good elasticity, not easy to deform, corrosion resistance, insulation, crisp, easy to wash and quick dry, etc., which is loved by people. [0003] Among them, polyester fiber is a hydrophobic synthetic fiber. The polyester molecular structure lacks active groups that can combine with dyes like cellulose or protein fibers. The polyester molecules are arranged relatively closely, and there are only smal...
