Abstract
The invention relates to a decontamination finishing agent used for polyester fiber, and a preparation method thereof. The finishing agent comprises, by weight, 1-5% of a polyester-polyether-polyamide block copolymer, 2-5% of glycerol or ethylene glycol or fluorine resin, and balance of water. The polyester-polyether-polyamide block copolymer is prepared from the raw materials of, by weight: 60-160 parts of polyethylene glycol, 13-40 parts of glycol, 14-26 parts of dimethyl terephthalate, 15-100 parts of polyamide, and 0.2-1 parts of metal acetate as a catalyst. With the in-bath crease-resisting agent provided by the invention, the polyester fiber is provided with good decontamination performance. Also, fluffy and soft texture, antistatic property, hydrophilic smoothness, and the like of polyester fiber can be improved. The decontamination finishing agent has excellent washing resistance, and does not fail after at least 30 times of washing.
Description
Technical field
The present invention relates to a kind of soil release finishing agent for polyester fiber and preparation method thereof.
Background technology
As everybody knows, the easy detergency ability of polyester fiber is relatively poor.In the laundering process that adopts usually, as in the conventional domestic washing machine, washing or hand-washing with syndetic bar, usually be very difficult to get on except dirt from textile material, and, suppose from textiles to get on except undesirable material, the dirt that remains in the washings is redeposited on textile material before finishing the washing cycle of being everlasting, and makes textiles to clean.Therefore, before dispatching from the factory polyester fiber is carried out modification, it is very necessary to make it have a good easy detergency ability.
Summary of the invention
Technical problem to be solved by this invention provides a kind of soil release finishing agent for polyester fiber.
Another technical problem to be solved by this invention provides a kind of preparation method of the soil release finishing agent for polyester fiber.
For solving above technical problem, the present invention adopts following technical scheme:
A kind of soil release finishing agent for polyester fiber, by weight percentage, it comprises the block copolymer of 1～5% polyester polyethers polyamide, 2～5% glycerine or ethylene glycol or fluorine resin, surplus is water, the composition of raw materials of the block copolymer of described polyester polyethers polyamide comprises following component in weight portion: 60～160 parts of polyethylene glycol, 13～40 parts of ethylene glycol, 14～26 parts of dimethyl terephthalate (DMT)s, 15～100 parts of polyamide and as 0.2～1 part of the acetic acid slaine of catalyst.
Preferably, described acetic acid slaine is selected from any in magnesium acetate, zinc acetate, calcium acetate, the tin acetate.
Preferably, the number-average molecular weight of described polyethylene glycol is 1000～4000.
Preferably, the number-average molecular weight of described polyamide is 2000～4000.
A kind of preparation method of the soil release finishing agent for polyester fiber, polyethylene glycol, ethylene glycol, dimethyl terephthalate (DMT), polyamide and the acetic acid slaine of formula ratio are dropped in the reactor, being warming up to 120～180 ℃ kept 140～200 minutes, continuing to be warming up to 200～230 ℃ kept 60～90 minutes, be-0.08 in vacuum then～-0.1MP, temperature is 230～290 ℃ and aggregates into the block copolymer that number-average molecular weight is 5000～15000 polyester polyethers polyamide, be cooled to 190～220 ℃ after blowing; The product, glycerine or the ethylene glycol that obtain behind the blowing or fluorine resin, water are mixed into solution by formula ratio, namely get described soil release finishing agent.
Beneficial effect of the present invention is:
Soil release finishing agent among the present invention not only makes polyester fiber have good easy detergency ability, and can improve the fluffy soft feeling, antistatic behaviour of polyester fiber, level and smooth hydrophily etc., and this soil release finishing agent has good washing fastness, can wash at least 30 times and does not lose efficacy.
