Embodiment 1

[0027] A fluffy finishing agent for polyester fibers, which is prepared through the following steps:

[0028] (1) Weigh 800 grams of polyethylene glycol (PEG4000), 150 grams of ethylene glycol, 125 grams of dihydroxypolyether, 140 grams of dimethyl terephthalate, and 150 grams of amino-terminated double-header silicone, 50g of 3-piperazinepropylmethyldimethoxysilane, 10g of magnesium acetate;

[0029] (2) Put the above materials into the reaction kettle, raise the temperature to 140°C and keep it for 180 minutes, then continue to raise the temperature to 220°C and keep it for 60 minutes. Then carry out polymerization at a vacuum degree of -0.08MPa and a temperature of 240°C to form a polyester polyether silicone oil block copolymer, which is discharged after cooling down to 190°C to obtain a finished product.

Embodiment 2

[0031] A fluffy finishing agent for polyester fibers, which is prepared through the following steps:

[0032] (1) Weigh 900 grams of polyethylene glycol (PEG2000), 140 grams of ethylene glycol, 140 grams of dihydroxypolyether, 165 grams of dimethyl terephthalate, and 180 grams of amino-terminated double-header silicone, 3-piperazinepropylmethyldimethoxysilane 60g, zinc acetate 6g;

[0033] (2) Put the above materials into the reaction kettle, raise the temperature to 150°C and keep it for 180 minutes, then continue to raise the temperature to 230°C and keep it for 60 minutes. Then carry out polymerization, and carry out polymerization at a vacuum degree of -0.08MPa and a temperature of 260°C to form a polyester polyether silicone oil block copolymer, which is discharged after cooling down to 200°C to obtain a finished product.

Embodiment 3

[0035] A fluffy finishing agent for polyester fibers, which is prepared through the following steps:

[0036] (1) Weigh 700 grams of polyethylene glycol, 125 grams of ethylene glycol, 125 grams of dihydroxypolyether, 130 grams of dimethyl terephthalate, 150 grams of amino-terminated double-header silicone, 3-piperidine 50 grams of azinepropylmethyldimethoxysilane, 10 grams of calcium acetate;

[0037] (2) Put the above materials into the reaction kettle, raise the temperature to 170°C and keep it for 180 minutes, continue to raise the temperature to 220°C and keep it for 60 minutes, then carry out polymerization at a vacuum degree of -0.09MPa and a temperature of 250°C to form Polyester polyether silicone oil block copolymer, after cooling down to 200°C, discharge to obtain the finished product.

Abstract

The invention relates to a fluffy and soft finishing agent used in polyester fiber, and a preparation method thereof. The agent comprises the following components, by weight: 120-160 parts of polyethylene glycol, 18-30 parts of glycol, 15-25 parts of dihydroxy polyether, 20-28 parts of dimethyl terephthalate, 10-30 parts of an amino-terminated double-head sealant organosilicon, 5-10 parts of 3-piperazine propyl dimethoxysilane, and 0.2-2 parts of metal acetate as a catalyst. The polyester fiber fluffy and soft finishing agent is a polyester-polyether-silicone oil block copolymer produced through a reaction with the raw materials and with a number average molecular weight of 8000-20000. When the polyester fiber provided by the invention is used for finishing polyester, the polyester fiber is provided with extremely fluffy and soft texture. Also, polyester fiber antistatic property and hydrophilic property can be improved. Therefore, the comfortableness of the modified polyester fiber can be greatly improved. Also, the cost of the polyester fiber provided by the invention is low.

Description

technical field [0001] The invention relates to the technical field of fabric finishing agents, in particular to a fluffy and softening finishing agent for polyester fibers and a preparation method thereof. Background technique [0002] As we all know, polyester fiber has poor fluffy softness, moisture absorption and perspiration, antistatic performance and easy decontamination performance. Therefore, the textiles processed with polyester fibers have poor wearability, are easy to stick to dirt, and are prone to static electricity. This will undoubtedly cause certain harm to human health. In order to overcome the shortcomings of polyester fiber and to meet the increasingly high requirements of the market for textiles, polyester fiber must be finished in order to improve its performance. [0003] Aiming at the lack of moisture absorption and perspiration of polyester fiber, the applicant filed an invention patent application titled "Moisture Absorption and Perspiration Comfo...
