Problems solved by technology

[0008] Pu Zongyao of Sichuan Institute of Textile Sciences and others found that anionic/cationic silicone emulsions are used to treat dyed fabrics together, that is, dyed fine-denier polyester fabrics are first impregnated with anionic or cationic silicone emulsions, and then impregnated with cationic or anionic silicone emulsions.

Embodiment 1

[0051] 1) Preparation of pre-emulsion: mix 20 g of methyl methacrylate and 1 g of ethylene glycol diacrylate as the oil phase; add 1 g of cationic emulsifier 1831 and nonionic emulsifier Pingping O-15 (both The dosage ratio is 2:1), 0.2 g of glacial acetic acid, dissolved in 31 g of deionized water as the water phase. Mix the water phase and the oil phase, and stir at 1500 rpm for 35 minutes at room temperature to obtain a pre-emulsion;

[0052] 2) Prepare the primer: add 0.35 g of 1831 and Pingping O-15 (the ratio of the two is 1:1), 0.06 g of azobisisobutylimidazoline hydrochloride and 47 g of deionized water, at room temperature Stir to dissolve evenly. The primer is all packed into a four-necked flask connected with stirring, thermometer, condenser and nitrogen pipe;

[0053] 3) Polymerization reaction: Inflate nitrogen into the flask with primer for 20 minutes to remove oxygen, stir at the same time, heat up the water bath, and when the temperature in the flask is stabl...

Embodiment 2

[0055] Step 1) According to Example 1, the crosslinking agent used was changed to 2 g ethylene glycol dimethacrylate, and the deionized water was 29.8 g;

[0056] Steps 2) and 3) are the same as in Example 1. The measured solid content of the darkening agent was 21.9%, and the monomer conversion rate was 99.6%.

Embodiment 3

[0058] 1) Preparation of pre-emulsion: Mix 25 g of methyl methacrylate and 2.5 g of ethylene glycol dimethacrylate into the oil phase; add 1.1 g of cationic emulsifier 1227 and nonionic emulsifier Pingping O-15 ( The ratio of the two is 2:1), 0.25 g of glacial acetic acid, dissolved in 28 g of deionized water as the water phase. Mix the water phase and the oil phase, and stir at 1500 rpm for 35 minutes at room temperature to obtain a pre-emulsion;

[0059] 2) Prepare the primer: add 0.5 g of 1227 and Pingping O-15 (the ratio of the two is 1:1), 0.09 g of azobisisobutylimidazoline hydrochloride and 42.6 g of deionized water, at room temperature Stir to dissolve evenly. The primer is all packed into a four-necked flask connected with stirring, thermometer, condenser and nitrogen pipe;

[0060] 3) Polymerization reaction: Inflate nitrogen into the flask with primer for 20 minutes to remove oxygen, stir at the same time, heat up the water bath, and when the temperature in the fl...

Abstract

The invention discloses an efficient deep dyeing promoter, and preparation and after treatment application methods thereof. The efficient deep dyeing promoter comprises 14-40 percent of DHMP, 0.5-6 percent of a cross-linking agent, 0.05-2 percent of a cationic emulsifier, 0.05-2 percent of a non-ionic emulsifier, 0.0015-0.4 percent of a water-soluble azo initiator, 0.005 to 0.5 percent of glacial acetic acid and 60 to 85 percent of deionized water. The efficient deep dyeing promoter provided by the invention is prepared by adopting a cationic polymerization method, and the preparation method comprises pre-emulsified liquid preparation, primer preparation and pre-emulsion dripping method polymerization reaction. The efficient deep dyeing promoter is applied through a two-step treatment application process with silicone emulsion. After the adoption of the efficient deep dyeing promoter, and the application method thereof, the deepening rate can greatly exceed the deepening rate in the prior art and can reach 80 percent and above, the colour difference is small, the hand feeling is improved, and influences on dry and wet rubbing fastness and soaping fastness of the fabric are small.

Description

technical field [0001] The invention belongs to the field of textile dyeing and finishing auxiliaries, and in particular relates to a high-efficiency darkening agent and its preparation and finishing application method. Background technique [0002] Polyester is the world's largest and most widely used synthetic fiber variety. Due to the constraints of fiber dyeing balance and color fastness, plus polyester has a high refractive index and smooth surface, its dye depth is relatively poor. When dyeing polyester fiber, it is necessary to add more dyes to achieve the required surface color depth. Even if the amount of dyes is increased in actual production, sometimes it cannot meet customer requirements. For example, it is difficult to achieve the black color required by the Arab region. It is especially difficult for fine denier / ultra fine denier polyester with high surface light reflectance to dye dark colors. In addition, due to the increasing pressure of environmental prote...
