Background technology
Polyester fiber is a large amount of a kind of synthetic fiber that use in field of textiles at present, and the use amount of polyester fiber is primary in the use amount of various synthetic fiber, in life neutralization work, often can touch polyester fiber.Polyester fiber can be used to be made into clothing etc.Polyester fiber textiles, by using finishing agent to arrange it, can improve the various resistance to fastness of polyester fiber, as wash resistance to fastness, the resistance to fastness that rubs, the resistance to fastness of sweat stain etc.In the middle of this, wash resistance to fastness very crucial, if the resistance to fastness of the washing of polyester fiber is lower, after repeatedly cleaning, the fabric of polyester fiber there will be the phenomenon that significantly fades, and has a strong impact on normal use.
Summary of the invention
The technical problem solving: conventional dacron fabric is having the large-area problem fading after repeatedly cleaning, and it is not high not pass through its soft degree of polyester fiber of Special Finishing.
Technical scheme: the invention discloses a kind of polyester fiber finishing agent and preparation method thereof, polyester fiber finishing agent is comprised of according to weight ratio following composition: dimethicone is that 2~5 parts, ammonium chloride are that 3~5 parts, palm wax are that 3~7 parts, polypropylene glycol are that 4~7 parts, ethyl acetate are that 5~10 parts, diethylenetriamine are that 2~4 parts, triethylene tetramine are that 2~3 parts, water are 130~145 parts.
A preparation method for polyester fiber finishing agent, comprises the following steps: (1) is 60 ℃~65 ℃ by retort Temperature Setting; (2) to dropping into water in retort, be that 130~145 parts, polypropylene glycol are that 4~7 parts, ethyl acetate are 5~10 parts, three kinds of compositions are stirred; (3) to adding dimethicone in retort, be that 2~5 parts, ammonium chloride are that 3~5 parts, palm wax are 3~7 parts again after stirring, stir; (4) retort is cooled to after room temperature, adding diethylenetriamine is that 2~4 parts, triethylene tetramine are 2~3 parts, with cutter, shears, and shearing rotating speed is 400rpm, and the time is 3min~5min.Wherein, prepare the dimethicone that finishing agent adds and be preferably 2 parts.Prepare the diethylenetriamine that finishing agent adds and be preferably 3~4 parts.Prepare the ammonium chloride that finishing agent adds and be preferably powder.
Beneficial effect: after dacron fabric arranges with finishing agent of the present invention, color fastness to washing (GB/T3921.1-1997) grade of dacron fabric is higher, COLOR FASTNESS is 5 grades, has promoted the soft degree of polyester fiber simultaneously, has promoted the quality of polyester fiber.
The specific embodiment
Embodiment 1
(1) by retort Temperature Setting, it is 60 ℃; (2) to dropping into water in retort, be that 130kg, polypropylene glycol are that 7kg, ethyl acetate are 10kg, three kinds of compositions are stirred; (3) to adding dimethicone in retort, be that 2kg, ammonium chloride are that 3kg, palm wax are 7kg again after stirring, stir; (4) retort is cooled to after room temperature, adding diethylenetriamine is that 4kg, triethylene tetramine are 2kg, with cutter, shears, and shearing rotating speed is 400rpm, and the time is 5min, after shearing finishes, prepares polyester fiber finishing agent.
Embodiment 2
(1) by retort Temperature Setting, it is 65 ℃; (2) to dropping into water in retort, be that 140kg, polypropylene glycol are that 4kg, ethyl acetate are 7kg, three kinds of compositions are stirred; (3) to adding dimethicone in retort, be that 3kg, ammonium chloride are that 5kg, palm wax are 5kg again after stirring, stir; (4) retort is cooled to after room temperature, adding diethylenetriamine is that 2kg, triethylene tetramine are 3kg, with cutter, shears, and shearing rotating speed is 400rpm, and the time is 3min, after shearing finishes, prepares polyester fiber finishing agent.
Embodiment 3
(1) by retort Temperature Setting, it is 62 ℃; (2) to dropping into water in retort, be that 145kg, polypropylene glycol are that 5kg, ethyl acetate are 5kg, three kinds of compositions are stirred; (3) to adding dimethicone in retort, be that 5kg, ammonium chloride are that 4kg, palm wax are 3kg again after stirring, stir; (4) retort is cooled to after room temperature, adding diethylenetriamine is that 3kg, triethylene tetramine are 2kg, with cutter, shears, and shearing rotating speed is 400rpm, and the time is 4min, after shearing finishes, prepares polyester fiber finishing agent.
Get the clothing of 100% polyester fiber, soak 3h with the finishing agent of embodiment 1, embodiment 2, embodiment 3, one soaks one rolls, and pick-up is 75%, is dried to dry at 95 ℃.Measured its color fastness to washing, testing standard is GB/T3921.1-1997, the results are shown in following table.
