Abstract
The invention discloses a high-temperature leveling agent and a preparation method thereof, and the technical scheme is characterized by comprising the following components in parts by weight: 20-30 parts of a nonionic surfactant; 10-15 parts of an anionic surfactant; 10-15 parts of a moisture absorption modifier; 40-50 parts of water; the preparation process of the moisture absorption modifier comprises the following steps: firstly, uniformly mixing 6-8 parts by weight of octyl phenol polyoxyethylene ether, 6-8 parts by weight of dodecenyl diol polyoxyethylene ether and 10-15 parts by weight of hydrogen-containing silicone oil, then adding 0.3-0.5 part by weight of platinum catalyst, mixing, heating to 140-170 ℃, and reacting for 3-5 hours to obtain reaction liquid; step two, uniformly mixing 15-20 parts of tea saponin and 10-12 parts of the reaction solution, heating to 80-100 ℃, and reacting for 2-3 hours to obtain a secondary reaction solution; and step three, uniformly mixing 6-8 parts of dodecylamine hydrochloride and 15-20 parts of the secondary reaction liquid, heating to 70-80 ℃, and continuously reacting for 4-5 hours to obtain the moisture absorption modifier. The moisture absorption modifier can modify the polyester fiber to improve the moisture absorption of the polyester fiber.
Description
Technical Field
The invention relates to a dyeing auxiliary agent, in particular to a high-temperature leveling agent and a preparation method thereof.
Background
The leveling agent is used for uniformly dispersing dye particles, and the consistency of the surface color depth, the chromatic light and the brilliant brightness of the fabric is ensured. Leveling agents generally consist of a variety of water-soluble surfactants, which are classified into a fibriphilic leveling agent and a dye-philic leveling agent according to the difference in mechanism of action. The mechanism of action of the fibriphilic leveling agent is as follows: the dye leveler is preferentially combined with the fiber to occupy the dyeing seat and block the combination of the dye and the fiber, so that the dye can be delayed from being dyed, and the dye can gradually replace the dye leveler from the fiber along with the rise of the temperature of the dye bath, thereby achieving the purpose of level dyeing. The mechanism of action of the dye-philic leveling agent is as follows: the affinity of the dye to the dye is greater than that of the dye to the fiber, before the dye is adsorbed by the fiber, the dye is firstly held by the leveling agent and then combined to generate a stable aggregate, the aggregate is gradually decomposed at high temperature, dye molecules are released and are gradually combined with the fiber, and the purpose of leveling is achieved.
Polyester fabrics need to be dyed at high temperature because of the tight arrangement of fibers, the strong hydrophobicity and the difficulty in dyeing at normal temperature. The disperse dye can be uniformly dispersed at normal temperature and is easy to agglomerate at high temperature, so that a high-temperature leveling agent is required to be added during dyeing to improve the high-temperature dispersibility of dye molecules and improve the dyeing uniformity.
Chinese patent with publication number CN103790043B discloses an environment-friendly high-temperature leveling agent, which is prepared by mixing the following components in percentage by mass: 45-50% of dodecyl benzoic acid propylene glycol polyoxyethylene ether, 35-45% of dodecyl diphenyl ether disulfonic acid sodium and 10-15% of ethylene glycol monophenyl ether, wherein the sum of the components is 100%.
The formula of the leveling agent takes polyoxyethylene ether emulsifier as a main component, which can help polyester fiber to be uniformly dyed, but the function of the leveling agent is also limited to the above. As is well known, polyester fabrics have poor moisture absorption, cannot effectively absorb sweat and quickly dry when used as underwear, and have poor wearing comfort, so that improvement is needed.
Disclosure of Invention
Aiming at the technical defects, the invention aims to provide a high-temperature leveling agent which can improve the dyeing uniformity and the moisture absorption of polyester fabrics.
In order to achieve the purpose, the invention provides the following technical scheme:
a high-temperature leveling agent comprises the following components in parts by weight:
20-30 parts of a nonionic surfactant;
10-15 parts of an anionic surfactant;
10-15 parts of a moisture absorption modifier;
40-50 parts of water;
the preparation process of the moisture absorption modifier comprises the following steps:
firstly, uniformly mixing 6-8 parts by weight of octyl phenol polyoxyethylene ether, 6-8 parts by weight of dodecenyl diol polyoxyethylene ether and 10-15 parts by weight of hydrogen-containing silicone oil, then adding 0.3-0.5 part by weight of platinum catalyst, mixing, heating to 140-170 ℃, and reacting for 3-5 hours to obtain reaction liquid;
