A kind of tablecloth finishing agent and preparation method thereof
Technical field
The present invention relates to a kind of finishing agent and preparation method thereof, particularly relate to a kind of finishing agent of preventing the balling-up of cotton tablecloth, promoting tablecloth anti-microbial property and preparation method thereof that has.
Background technology
The material of tablecloth is more, has the various material such as natural cotton, chemical synthetic fiber.The tablecloth of cotton is after repeatedly using, and pilling effect is comparatively obvious, has caused the out-of-flatness of tablecloth, has affected the normal use in life.After tablecloth spreads on the table, owing to often contacting with food, after long-time use, have vegetative phenomenon, the breeding of bacterium is a larger harm to people.Finishing agent is arranged tablecloth, can promote the performance of tablecloth.Conventional finishing agent arranges after tablecloth, and its ANTIPILLING grade still only has 3 grades, and it is not high to colibacillary inhibiting rate yet, and these problems all also need related personnel to carry out deep research and development to it.
Summary of the invention
The technical problem solving: the pilling effect of cotton tablecloth is comparatively serious, the poor problem of inhibition Escherichia coli performance of the tablecloth of cotton.
Technical scheme: the invention discloses a kind of method of tablecloth finishing agent and preparation thereof, tablecloth finishing agent is comprised of according to weight ratio following composition: DTAB is that 2~4 parts, dimethyl fumarate are that 2~3 parts, Potassium dodecylbenzenesulfonate are that 5~7 parts, sodium hydrogensulfite are that 4~6 parts, triacetin are that 3~4 parts, triethyl citrate are that 5~7 parts, adipic acid are that 15~18 parts, water are 160~180 parts.
A kind of preparation method of tablecloth finishing agent, preparation method comprises the following steps: (1) gets DTAB is that 2~4 parts, dimethyl fumarate are that 2~3 parts, Potassium dodecylbenzenesulfonate are 5~7 parts, put into stainless steel tank body, stir after being heated to 60 ℃; (2) getting sodium hydrogensulfite is that 4~6 parts, adipic acid are that 15~18 parts, water are 160~180 parts, will under sodium hydrogensulfite and adipic acid water room temperature, be uniformly dissolved; (3) mixed liquor step (1) being prepared is put in the mixed liquor in step (2), under room temperature, stirs; (4) to adding triacetin in mixed liquor, be that 3~4 parts, triethyl citrate are 5~7 parts again, adopt cutter to shear, cutter rotating speed is 5000rpm, and shear time is 4~7min; (5) shear completely, dressing liquid is sealed to preservation.
The DTAB adding during preparation is preferably 3~4 parts.The Potassium dodecylbenzenesulfonate adding during preparation is preferably 7 parts.The time of shearing during preparation is preferably 7min.
beneficial effect:the finishing agent preparing arranged after cotton tablecloth, and the ANTIPILLING grade of tablecloth is 5 grades, and it is 86% to 89% to colibacillary inhibiting rate, has suppressed significantly Escherichia coli.Arrange cotton tablecloth later and possessed good ANTIPILLING and antibacterial performance.
The specific embodiment
Embodiment 1
(1) getting DTAB is that 2kg, dimethyl fumarate are that 3kg, Potassium dodecylbenzenesulfonate are 5kg, puts into stainless steel tank body, stirs after being heated to 60 ℃; (2) getting sodium hydrogensulfite is that 6kg, adipic acid are that 15kg, water are 180kg, will under sodium hydrogensulfite and adipic acid water room temperature, be uniformly dissolved; (3) mixed liquor step (1) being prepared is put in the mixed liquor in step (2), under room temperature, stirs; (4) to adding triacetin in mixed liquor, be that 3kg, triethyl citrate are 7kg again, adopt cutter to shear, cutter rotating speed is 5000rpm, and shear time is 7min; (5) shear completely, dressing liquid is sealed to preservation.
Embodiment 2
(1) getting DTAB is that 3kg, dimethyl fumarate are that 2kg, Potassium dodecylbenzenesulfonate are 7kg, puts into stainless steel tank body, stirs after being heated to 60 ℃; (2) getting sodium hydrogensulfite is that 4kg, adipic acid are that 16kg, water are 160kg, will under sodium hydrogensulfite and adipic acid water room temperature, be uniformly dissolved; (3) mixed liquor step (1) being prepared is put in the mixed liquor in step (2), under room temperature, stirs; (4) to adding triacetin in mixed liquor, be that 3kg, triethyl citrate are 5kg again, adopt cutter to shear, cutter rotating speed is 5000rpm, and shear time is 4min; (5) shear completely, dressing liquid is sealed to preservation.
Embodiment 3
(1) getting DTAB is that 4kg, dimethyl fumarate are that 3kg, Potassium dodecylbenzenesulfonate are 6kg, puts into stainless steel tank body, stirs after being heated to 60 ℃; (2) getting sodium hydrogensulfite is that 5kg, adipic acid are that 18kg, water are 170kg, will under sodium hydrogensulfite and adipic acid water room temperature, be uniformly dissolved; (3) mixed liquor step (1) being prepared is put in the mixed liquor in step (2), under room temperature, stirs; (4) to adding triacetin in mixed liquor, be that 4kg, triethyl citrate are 6kg again, adopt cutter to shear, cutter rotating speed is 5000rpm, and shear time is 5min; (5) shear completely, dressing liquid is sealed to preservation.
By 1 times of the finishing agent dilute with water of embodiment 1, embodiment 2, embodiment 3, then get respectively textile tablecloth and put under aqueous finish solution room temperature and soak 90min, soak at latter 85 ℃ and dry.Measure its anti-pilling property, bioassay standard is GB/T4802.2-1997.The bioassay standard of Escherichia coli inhibiting rate is FZ/T 73023-2006, and result is as follows.
