Problems solved by technology

Due to the unique fiber properties of polyester fiber, it can only be dyed with disperse dyes with the same hydrophobicity, high temperature and high pressure dyeing method or hot melt dyeing method. These two dyeing methods require high energy consumption and high equipment requirements.
With the development of fabric diversification and people's pursuit of fabric performance diversification, the variety of blended fabrics is gradually increasing, and polyester fabrics are no longer a single variety. Some fibers with poor heat resistance, such as silk, wool, spandex, etc. When polyester fiber is blended, high temperature and high pressure dyeing or hot melt dyeing will cause great damage, resulting in limited dyeing temperature
[0005] The traditional low-temperature dyeing usually uses winter clear oil, methylnaphthalene, o-phenylphenol, etc. as the dyeing carrier. Although the low-temperature dyeing of polyester has been realized to a certain extent, the dyeing carrier itself has high toxicity, heavy odor, and is difficult to biodegrade. Problems such as unloading are contrary to the current environmental protection purpose

Abstract

The invention discloses a low-temperature polyester fiber dyeing method based on diethyl phthalate. According to the low-temperature polyester fiber dyeing method based on diethyl phthalate, a polyester fabric is dyed by using diethyl phthalate as a dyeing auxiliary agent, the dyeing temperature is controlled at 103-105 DEG C, the color depth, the chromatic light, the color fastness and the dyeing penetration of the obtained fabric are the same as the fabric obtained through the traditional high temperature and high pressure dyeing, the mightiness and leveling property of the fabric are improved, and the friction and the soaping fastness achieve the national standard of more than grade 4. Compared to the traditional high temperature and high pressure dyeing method, the low-temperature polyester fiber dyeing method of the present invention has advantages of substantially-reduced dyeing temperature, dyeing time shortening, energy saving, consumption reducing, efficiency improving, and production cost reducing; and the diethyl phthalate adopted as the dyeing auxiliary agent is the environmentally friendly organic ester so as to achieve the environmentally friendly low temperature dyeing.

Description

technical field [0001] The invention belongs to the technical field of textile printing and dyeing, and relates to a low-temperature dyeing method for polyester fibers, in particular to a low-temperature dyeing method for polyester fibers based on diethyl phthalate. Background technique [0002] Polyester fiber (polyester fiber) is a synthetic fiber obtained by spinning polyester obtained by polycondensation of organic dibasic acid and dibasic alcohol, referred to as PET fiber, which is currently the largest variety of synthetic fiber. [0003] Polyester fiber is the main component of polyester fiber. Compared with natural fiber and recycled fiber, synthetic fiber has the advantages of low relative density, high strength and chemical corrosion resistance. Polyester fiber has a variety of excellent properties of synthetic fibers, among which heat resistance is more prominent, in addition, its breaking strength and modulus of rupture are high, heat resistance and light resista...
