Embodiment 1

[0051] 1), 0.02 moles (n=150, molecular weight about 7350) of allyl polyether (R 1 = H and R 1 =CH 3 The ratio of 10:5, that is, -CH in allyl polyether 2 CH 2 O-Link and -CH 2 CH(CH 3 ) into the reaction flask, at 25°C, add 0.01 mole of hydrogen-terminated silicone oil (z=1, x=62, molecular weight about 5000) with the structure shown in formula III, and stir evenly. Heat up to 110°C, start to drop an appropriate amount of isopropanol solution of chloroplatinic acid, so that the concentration of chloroplatinic acid in the system is 30 ppm by weight, and keep the reaction for 5 hours. Sampling was carried out by infrared spectroscopy to determine that the H peak at 2222-2128 cm-1 disappeared, and the reaction was terminated. After cooling to below 40°C, the polyether silicone copolymer with the structure shown in formula IV is obtained, and the appearance is light yellow oily liquid.

Embodiment 2

[0055] 1), 0.02 moles (n=30, molecular weight about 1520) of allyl polyether (R 1 = H and R 1 =CH 3 The ratio of 10:5) was added to the reaction flask, and 0.01 mole of hydrogen-terminated silicone oil (z=10, x=29, molecular weight about 6000) with the structure shown in formula III was added at 25°C, and stirred evenly. Heat up to 100°C, start to drop an appropriate amount of isopropanol solution of chloroplatinic acid, so that the concentration of chloroplatinic acid in the system is 50 ppm by weight, and keep the reaction for 5 hours. The H peak at 2222-2128 cm-1 as measured by infrared spectroscopy disappeared, and the reaction was terminated. After cooling to below 40°C, the polyether silicone copolymer with the structure shown in formula IV is obtained, and the appearance is light yellow oily liquid.

[0059] 1), 0.02 moles (n=100, molecular weight about 4900) of allyl polyether (R 1 = H and R 1 =CH 3 ratio of 10:5) into the reaction flask, at 25°C, add 0.01 mole of hydrogen-terminated silicone oil (z=15, x=11, molecular weight is about 6500) with the structure shown in formula III, stir evenly, and heat up to 150°C , start to drop an appropriate amount of chloroplatinic acid isopropanol solution, so that the weight percentage concentration of chloroplatinic acid in the system is 50ppm, and keep the reaction for 5 hours. The H peak at 2222-2128 cm-1 as determined by infrared spectroscopy disappeared, and the reaction was terminated. After cooling to below 40°C, the polyether silicone copolymer with the structure shown in formula IV is obtained, and the appearance is light yellow oily liquid.

[0060] 2), 0.01 moles of polyether (m=82, molecular weight about 4000, R 3 = H and R 3 =CH 3 The ratio of 10:5) was added to the reaction flask with a fractionation device, and t...

Abstract

The invention belongs to the technical field of after-finishing of textiles and relates to a multifunctional polyester fiber finishing material which comprises the structure shown in a general formula I, wherein n represents an integer from 5 to 200; m represents an integer from 1 to 110; z represents an integer from 1 to 30; x represents an integer from 10 to 100; R1=H or CH3; R2=H or SO3Na; andR3=H or CH3. A macromolecular compound as shown in the general formula I is formed by virtue of block copolymerization of polyether, an organic fluosilicic material and a polyurethane material, is used for after-finishing of polyester fiber when serving as the polyester fiber finishing material, and has the functions of antistatic property, soft and smooth feather feel, easiness in stain removal,moisture absorption, sweat removal, high color fastness and the like.

Description

technical field [0001] The invention belongs to the technical field of polymer and textile finishing materials, and in particular relates to a polyester fiber finishing material and a preparation method thereof. Background technique [0002] Polyester (polyester fiber) is a widely used synthetic fiber, which has superior physical and mechanical properties such as high strength, good elasticity, and high rigidity. However, polyester (polyester fiber) is a hydrophobic fiber with poor hygroscopicity, and it is easy to generate static electricity, and it is difficult for the charge to escape. During wearing, polyester (polyester fiber) fabric not only absorbs a large amount of dust and is easy to occupy dirt, but also entangles between clothes and human body, and between clothes and clothes. Therefore, it has become an important issue to eliminate or weaken the static electricity of polyester (polyester fiber) and to give polyester (polyester fiber) a soft and smooth feel. [...
