Problems solved by technology

However, most hydrophilic treatment agents have defects such as large dosage and poor washing resistance.
Large dosage cannot meet the requirement of washing auxiliaries in the washing process, which can endow polyester fabrics with hydrophilic, antistatic and easy decontamination functions by adding a small amount

Embodiment 1

[0026] In a 250ml reactor, put 24.3g DMT, 18.6g ethylene glycol, 0.05g zinc acetate, and heat to 150°C under the protection of nitrogen. After the DMT melts, start stirring and continue to heat up. The temperature rises to 180°C, and methanol begins to evaporate. out, continue to heat up to 195°C, and react for 3 hours. When the amount of methanol evaporated reached 90% to 95% of the theoretical amount, PEG, 0.025g polycondensation catalyst and 0.5ml antioxidant triphenyl phosphite were dropped into 56.3g molecular weight of 1500, and the temperature was continued to rise to 260°C. MPa) in polycondensation for 1 hour to obtain the polyester polyether block copolymerization type multifunctional detergent builder. Add 0.75g / L of this detergent additive in the washing process in the household washing process. After the treatment, the polyester fabric has a capillary effect of 11.3cm / 15min and a surface resistance of 7.0×10 8 Ω, half-life 3.28s, easy decontamination rate 85.8%; a...

Embodiment 2

[0028] Put 24.3g of DMT, 22.8g of propylene glycol, and 0.05g of zinc acetate into a 250ml reactor, and heat it to 150°C under the protection of nitrogen. After the DMT melts, stir and continue to heat up to 200°C, and react for 2.5 hours. When the amount of methanol distilled out reaches 90%~95% of the theoretical amount, drop into 56.3g molecular weight as PEG of 1500, 0.025g polycondensation reaction catalyst and 0.5ml antioxidant triphenyl phosphite, continue to be warming up to 250 ℃, in vacuum ( 0.04MPa) in polycondensation for 1.5 hours to obtain the polyester polyether block copolymerization type multifunctional detergent builder. Add 0.75g / L of this detergent additive in the household washing and rinsing process of polyester fabrics. After treatment, the wool effect of polyester fabrics is 10.4cm / 15min, and the surface resistance is 7.9×10 8 Ω, the half-life is 4.18s, and the decontamination rate is 80.8%.

Embodiment 3

[0030] Put 24.3g of DMT, 27.0g of butanediol, and 0.05g of zinc acetate into a 250ml reactor, heat it to 150°C under nitrogen protection, start stirring after the DMT melts and continue to heat up to 220°C, and react for 2.5 hours. When the amount of methanol distilled reaches 90% to 95% of the theoretical amount, drop in 56.3g of PEG with a molecular weight of 1500, 0.025g of polycondensation catalyst and 0.5ml of triphenyl phosphite, and continue to heat up to 270°C. ) in polycondensation for 0.5 hour to obtain the polyester polyether block copolymerization type multifunctional detergent builder. Add 0.75g / L of this detergent additive in the household washing and rinsing process, the polyester fabric capillary effect after treatment is 9.6cm / 15min, and the surface resistance is 8.5×10 8 Ω, the half-life is 4.52s, and the decontamination rate is 79.5%.

Abstract

The invention discloses a multifunctional cleaning assistant for polyester containing textile and a preparation method thereof. The multifunctional cleaning assistant for polyester containing textile is polyester-polyether block copolymer with molecule containing polyester chain segment and polyether chain segment. The preparation method comprises the following steps: 1) 100 weight portions of diatomic ester, 70 to 80 weight portions of diatomic alcohol and 0.2 to 0.6 weight portions of transesterification catalyst are added into a reaction kettle, nitrogen is pumped in and the reaction kettle is heated until the temperature rises to 150 DEG C; stirring is carried out, after diatomic ester is totally melted, the temperature is raised gradually to the reaction temperature of transesterification reaction of 180 to 220 DEG C and the transesterification reaction lasts 2.5 to 3 hours; 2) when the steamed methanol steamed reaches a theoretical quantity of 90 to 95 percent, 60 to 926 weight portions of polyether, 0.1 to 0.5 weight portion of polycondensation catalyst, 2 to 4 weight portions of antioxidant are added, heating is continued until the temperature reaches that of polycondensation reaction of 230 to 280 DEG C and polycondensation lasts 0.5 to 1.5 hours after vacuum-pumping. The multifunctional cleaning assistant of the invention is applied to the cleaning or rinsing working procedure during the course of household cleaning with an amount of 0.5 to 1g/ L, can provide polyester containing textile with multiple functions such as hydrophile, anti-static electricity, and being easy to decontaminate, etc. and has excellent washability.

Description

technical field [0001] The invention relates to the field of light industrial daily necessities chemistry, in particular to a multifunctional washing aid for polyester-containing fabrics, its preparation method and application. Background technique [0002] Although polyester fabric has the advantages of good elasticity, high strength and high initial modulus, because it is a typical hydrophobic fiber, the standard moisture regain is only 0.4%, so it is easy to static electricity, easy to stain, poor in water absorption and sweat absorption, and it is easy to wear when taking it. Stuffy feeling, thereby affecting the wearing comfort of polyester fabric. For this reason, various polyester fabric hydrophilic treatment agents have emerged as the times require, and the wearing comfort, antistatic property and easy decontamination performance of polyester fabrics treated with hydrophilic treatment agents have been improved to a certain extent. There are already many types of hyd...
