Embodiment 1

[0044] In this embodiment, a polyester dyeing carrier is provided, the proportions of each component in the polyester dyeing carrier are: 60% diethylene glycol phthalate, 10% dodecylbenzenesulfonate Ammonium Acetate, 30% AEO-9. The preparation method of the polyester dyed carrier is as follows.

[0045] Step 101. Using p-toluenesulfonic acid as a catalyst, add phthalic anhydride to ethylene glycol, keep the temperature at 60°C for 1 hour, raise the temperature to 110°C, and carry out esterification under the condition of vacuum degree -0.07MPa React for 2h to obtain diethylene glycol phthalate. Wherein, the mol ratio of phthalic anhydride and ethylene glycol is 1:2.2, and the addition of p-toluenesulfonic acid is 0.5% of the total mass of phthalic anhydride and ethylene glycol;

[0046] Step 102. The diethylene glycol phthalate obtained in step 101 and benzoic acid were dehydrated and esterified for 3 hours at a temperature of 140° C. and a vacuum of -0.07 MPa under the acti...

Embodiment 2

[0049] In this embodiment, a polyester dyeing carrier is provided. The proportions of the components in the polyester dyeing carrier are: 60% dipropylene glycol phenylacetate phthalate, 15% sodium dodecylbenzene sulfonate, and 25% flat plus O-20. The preparation method of the polyester dyeing carrier specifically includes the following steps.

[0050] Step 101. Using p-toluenesulfonic acid as a catalyst, add phthalic anhydride to propylene glycol, keep the temperature at 70°C for 1.2h, raise the temperature to 120°C, and carry out esterification under the condition of vacuum degree -0.08MPa 2.2h, to obtain dipropylene glycol phthalate. Wherein, the mol ratio of phthalic anhydride and propylene glycol is 1:2.4, and the addition of the p-toluenesulfonic acid is 1% of the total mass of phthalic anhydride and propylene glycol;

[0051] Step 102. The dipropylene glycol phthalate obtained in step 101 and phenylacetic acid were dehydrated and esterified for 3.2 hours at a temperatu...

Embodiment 3

[0054] In this embodiment, a polyester dyeing carrier is provided. The proportions of the components in the polyester dyeing carrier are: 60% diethylene glycol cinnamate phthalate, 20% calcium dodecylbenzenesulfonate, and 20% TO-10. The preparation method of the polyester dyeing carrier specifically includes the following steps.

[0055] Step 101. Using p-toluenesulfonic acid as a catalyst, add phthalic anhydride to diethylene glycol, keep the temperature at 80°C for 1.6h, raise the temperature to 130°C, and carry out under the condition of vacuum degree -0.09MPa After 2.5 hours of esterification, diethylene glycol phthalate was obtained. Wherein, the mol ratio of phthalic anhydride and diethylene glycol is 1:2.6, and the addition of p-toluenesulfonic acid is 2% of the total mass of phthalic anhydride and diethylene glycol;

[0056] Step 102. The diethylene glycol phthalate and cinnamic acid obtained in step 101 are dehydrated and esterified under the conditions of 160° C. a...

Abstract

A terylene dyeing carrier and a preparing method thereof are provided. The carrier includes 60-80% by mass of di(polyol) phthalate aromatic ester, 10-20% by mass of an anionic emulsifier, and 10-20% by mass of a nonionic surfactant. The carrier has advantages of simple components, a low cost, capability of being environmentally friendly, nontoxic and odorless, good dyeing accelerating performance,and the like. In addition, the process and steps of the preparing method are simple and process controllability is high.

Description

technical field [0001] The invention relates to the field of polyester dyeing carriers, in particular to a polyester dyeing carrier and a preparation method thereof. Background technique [0002] In recent years, with the sustained and rapid growth of China's economy and the continuous improvement of domestic consumption capacity, the domestic demand for polyester fibers has also continued to grow. China's polyester fiber production capacity has grown at an astonishing rate, making my country gradually develop into an important processing base for polyester products in the world, and has become the country with the largest polyester fiber output in the world. [0003] Polyester fiber has excellent performance and has a wide range of application fields. Its excellent performance makes it one of the fastest growing and highest-yielding varieties of synthetic fibers. Due to the high degree of crystallinity, orientation and glass transition temperature of polyester fibers, the ...
