Embodiment 1

[0014] The embodiment of the present invention provides a polyester dyeing and repairing agent, which is made by mixing the following raw materials in parts by mass: 40 parts of diethylene glycol benzyl dibenzoate DEDB, 30 parts of rapeseed oleic acid polyethylene glycol 600 diester, 4 parts 600# sulfonate and 10 parts of methanol.

[0015] The above polyester dyeing and repairing agent can be prepared by the following method: add 40 parts of diethylene glycol dibenzoate benzyl DEDB, 30 parts of rapeseed oleic acid polyethylene glycol 600 diester, 4 parts of 600# sulfonated compound and 10 parts of methanol Put it into a container, mix evenly, and prepare the above-mentioned polyester dyeing and repairing agent.

Embodiment 2

[0017] The embodiment of the present invention provides a polyester dyeing and repairing agent, which is made by mixing the following raw materials in parts by mass: 45 parts of diethylene glycol benzyl dibenzoate DEDB, 35 parts of rapeseed oleic acid polyethylene glycol 600 diester, 7 parts 600# sulfonate and 15 parts of methanol.

[0018] The above-mentioned polyester dyeing and repairing agent can be prepared by the following method: 45 parts of diethylene glycol dibenzoate benzyl DEDB, 35 parts of rapeseed oleic acid polyethylene glycol 600 diester, 7 parts of 600# sulfonated compound and 15 parts of methanol are added Put it into a container, mix evenly, and prepare the above-mentioned polyester dyeing and repairing agent.

Embodiment 3

[0020] The embodiment of the present invention provides a polyester dyeing and repairing agent, which is made by mixing the following raw materials in parts by mass: 50 parts of diethylene glycol benzyl dibenzoate DEDB, 40 parts of rapeseed oleic acid polyethylene glycol 600 diester, 10 parts 600# sulfonate and 20 parts of methanol.

[0021] The above-mentioned polyester dyeing and repairing agent can be prepared by the following method: 50 parts of diethylene glycol dibenzoate benzyl DEDB, 40 parts of rapeseed oleic acid polyethylene glycol 600 diester, 10 parts of 600# sulfonated compound and 20 parts of methanol are added Put it into a container, mix evenly, and prepare the above-mentioned polyester dyeing and repairing agent.

[0022] The present embodiment has limited the optimal mass ratio of added diethylene glycol dibenzoate benzyl ester DEDB, rapeseed oleic acid polyethylene glycol 600 diester, 600# sulfonated compound and methyl alcohol to be 50:40:10:20, Under this...

Abstract

A polyester dyeing repair agent is characterized by being prepared from raw materials in parts by mass as follows: 40-50 parts of DEDB (diethylene glycol dibenzoate), 30-40 parts of polyethylene glycol 600 dioleate from rapeseeds, 4-10 parts of 600 # sulfonate and 10-20 parts of methanol through mixing.

Description

technical field [0001] The invention relates to the field of dyeing and repairing agents, in particular to a polyester dyeing and repairing agent. 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 purified terephthalic acid (PTA) or dimethyl terephthalate (DMT) and ethylene glycol (EG) through esterification or transesterification and polycondensation reactions— - Polyethylene terephthalate (PET), fibers made by spinning and post-processing. It has many advantages such as light weight, good elasticity, and wear resistance, and is often made into clothing. [0003] Polyester dyeing usually uses disperse dyes to dye polyester fibers in an acidic environment of 130-140°C. Due to the problems of polyester fibers and dyes, it is difficult to dye evenly, resulting in color spots, color flowers, color difference, blurring, etc. question. In...
