Problems solved by technology

Early hydrophilic silicone oils, such as epoxy / polyether modified silicone oils, were mostly amino silicone oils with polyether chain links in their side chains. Although they could endow fabrics with a certain degree of softness and antistatic properties, their wettability and ease of removal Poor staining performance, poor washing performance of finished fabrics

Embodiment 1

[0047] Add 23.3g (0.007456mol) WS-62M, 114.6g (0.2865mol) polyethylene glycol 400 into the dry there-necked flask, pass N 2 Under air protection, the temperature of the water bath was raised to 65°C and stirred evenly, then 38.0g (0.2262mol) HDI was added dropwise thereto, and then the temperature was raised to 70°C, dibutyltin dilaurate catalyst was added dropwise, and the reaction was carried out at constant temperature for 2 hours. Then the temperature was raised to 90°C, 8.8g (0.0427mol) DL-602 and catalyst KOH were added to the reaction system, and the reaction was carried out at constant temperature for 5h. The temperature was lowered to 65°C, and an appropriate amount of acetic acid was added dropwise to the reaction system for neutralization until the pH was 6. Then lower the temperature to 20°C, slowly drop deionized water into the system to disperse, and then stir at constant temperature for 2 hours to obtain the polyether block amino silicone oil softening agent PEA...

[0049] Add 24.8g (0.007936mol) WS-62M, 122.5g (0.3062mol) polyethylene glycol 400 into the dry there-necked flask, pass N 2 Under air protection, heat the water bath to 65°C and stir evenly, then add 37.9g ​​(0.2256mol) HDI dropwise thereto, then raise the temperature to 70°C, add dibutyltin dilaurate catalyst dropwise, and react at constant temperature for 1.5-2h. Then the temperature was raised to 95°C, 9.3g (0.045mol) DL-602 and catalyst KOH were added to the reaction system, and the reaction was carried out at constant temperature for 5h. The temperature was lowered to 65°C, and an appropriate amount of acetic acid was added dropwise to the reaction system for neutralization until the pH was 6. Then the temperature was lowered to 20°C, and deionized water was slowly added dropwise to the system, and then stirred at a constant temperature for 2 hours to obtain the polyether block amino silicone oil softening agent PEAS2.

Embodiment 3

[0051] Add 31g (0.00992mol) WS-62M, 125.3g (0.3132mol) polyethylene glycol 400 into the dry there-necked flask, pass N 2 Under gas protection, the temperature of the water bath was raised to 65°C and stirred evenly, then 36.2g (0.2155mol) HDI was added dropwise thereto, and then the temperature was raised to 75°C, dibutyltin dilaurate catalyst was added dropwise, and the reaction was carried out at constant temperature for 2h.

Abstract

The invention provides a polyether block amino silicone softening finishing agent, its preparation method and application. The finishing agent is prepared by carrying out a reaction of diisocyanate, polyether polylol and hydroxy silicone oil to obtain polyether block organic silicon polyurethane comprising OH end groups, carrying out a chain extending reaction on the polyether block organic silicon polyurethane comprising OH end groups through silane coupling agent, and adding acid neutralization and water dispersion. The softening finishing agent provided by the invention has good stable effect on electrolyte, acid, alkali, hard water and the like, fabrics processed by using the finishing agent has fabulously good softness, smooth, good hydrophilicity, and can not be easily changed into yellow.

Description

technical field [0001] The invention relates to a textile processing aid, and furthermore, to a water-soluble polyether block amino silicone oil softening finishing agent and its preparation method and application. Background technique [0002] At present, the requirements for textiles in the market are getting higher and higher. While pursuing super soft, super smooth and super fluffy fabrics, textiles are also required to have good moisture absorption (perspiration), antistatic properties, antifouling and easy decontamination properties, Comfortable to wear; the traditional blind pursuit of super soft and smooth fabrics but water repellent and non-hygroscopic (sweat), not anti-static, stuffy and uncomfortable to wear, and even harmful to the health of the wearer has been gradually abandoned by people. Most of the silicone fabric finishing agents that are being developed today have excellent properties such as moisture absorption and perspiration, antistatic, non-ironing, f...
