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 have prevent the balling-up of cotton tablecloth, the finishing agent promoting tablecloth anti-microbial property and preparation method thereof.
Background technology
The material of tablecloth is more, has the various material such as natural cotton, chemical synthetic fiber.After a number of uses, pilling effect is comparatively obvious, result in the out-of-flatness of tablecloth, have impact on the normal use in life for the tablecloth of cotton.Tablecloth paving on the table after, owing to often contacting with food, for a long time have vegetative phenomenon after use, the breeding of bacterium is a larger harm to people.Finishing agent is arranged tablecloth, the performance of tablecloth can be promoted.After conventional finishing agent arranges tablecloth, 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 solved: the problem that the pilling effect of cotton tablecloth is comparatively serious, the suppression Escherichia coli performance of the tablecloth of cotton is poor.
Technical scheme: a kind of method that the invention discloses tablecloth finishing agent and preparation thereof, tablecloth finishing agent is made up of according to weight ratio following composition: DTAB is 2 ~ 4 parts, dimethyl fumarate is 2 ~ 3 parts, Potassium dodecylbenzenesulfonate is 5 ~ 7 parts, sodium hydrogensulfite is 4 ~ 6 parts, triacetin is 3 ~ 4 parts, triethyl citrate is 5 ~ 7 parts, adipic acid is 15 ~ 18 parts, water is 160 ~ 180 parts.
A kind of preparation method of tablecloth finishing agent, preparation method comprises the following steps: (1) gets that DTAB is 2 ~ 4 parts, dimethyl fumarate is 2 ~ 3 parts, Potassium dodecylbenzenesulfonate is 5 ~ 7 parts, put into stainless steel tank body, stir after being heated to 60 DEG C; (2) get that sodium hydrogensulfite is 4 ~ 6 parts, adipic acid is 15 ~ 18 parts, water is 160 ~ 180 parts, be uniformly dissolved under sodium hydrogensulfite and adipic acid hydroecium temperature; (3) put in the mixed liquor in step (2) by the mixed liquor that step (1) prepares, stirred at ambient temperature is even; (4) in mixed liquor, add that triacetin is 3 ~ 4 parts, triethyl citrate is 5 ~ 7 parts again, adopt cutter to shear, cutter rotating speed is 5000rpm, and shear time is 4 ~ 7min; (5) shear complete, dressing liquid is carried out sealing preserve.
The DTAB added during preparation is preferably 3 ~ 4 parts.The Potassium dodecylbenzenesulfonate added during preparation is preferably 7 parts.The time of shearing during preparation is preferably 7min.
beneficial effect:after the finishing agent prepared arranged cotton tablecloth, the ANTIPILLING grade of tablecloth is 5 grades, and it is 86% to 89% to colibacillary inhibiting rate, inhibits Escherichia coli significantly.Cotton tablecloth after arrangement has possessed good ANTIPILLING and antibacterial performance.
Detailed description of the invention
Embodiment 1
(1) get that DTAB is 2kg, dimethyl fumarate is 3kg, Potassium dodecylbenzenesulfonate is 5kg, put into stainless steel tank body, stir after being heated to 60 DEG C; (2) get that sodium hydrogensulfite is 6kg, adipic acid is 15kg, water is 180kg, be uniformly dissolved under sodium hydrogensulfite and adipic acid hydroecium temperature; (3) put in the mixed liquor in step (2) by the mixed liquor that step (1) prepares, stirred at ambient temperature is even; (4) in mixed liquor, add that triacetin is 3kg, triethyl citrate is 7kg again, adopt cutter to shear, cutter rotating speed is 5000rpm, and shear time is 7min; (5) shear complete, dressing liquid is carried out sealing preserve.
Embodiment 2
(1) get that DTAB is 3kg, dimethyl fumarate is 2kg, Potassium dodecylbenzenesulfonate is 7kg, put into stainless steel tank body, stir after being heated to 60 DEG C; (2) get that sodium hydrogensulfite is 4kg, adipic acid is 16kg, water is 160kg, be uniformly dissolved under sodium hydrogensulfite and adipic acid hydroecium temperature; (3) put in the mixed liquor in step (2) by the mixed liquor that step (1) prepares, stirred at ambient temperature is even; (4) in mixed liquor, add that triacetin is 3kg, triethyl citrate is 5kg again, adopt cutter to shear, cutter rotating speed is 5000rpm, and shear time is 4min; (5) shear complete, dressing liquid is carried out sealing preserve.
Embodiment 3
(1) get that DTAB is 4kg, dimethyl fumarate is 3kg, Potassium dodecylbenzenesulfonate is 6kg, put into stainless steel tank body, stir after being heated to 60 DEG C; (2) get that sodium hydrogensulfite is 5kg, adipic acid is 18kg, water is 170kg, be uniformly dissolved under sodium hydrogensulfite and adipic acid hydroecium temperature; (3) put in the mixed liquor in step (2) by the mixed liquor that step (1) prepares, stirred at ambient temperature is even; (4) in mixed liquor, add that triacetin is 4kg, triethyl citrate is 6kg again, adopt cutter to shear, cutter rotating speed is 5000rpm, and shear time is 5min; (5) shear complete, dressing liquid is carried out sealing preserve.
By the finishing agent dilute with water 1 times of embodiment 1, embodiment 2, embodiment 3, then get respectively under aqueous finish solution room temperature put into by textile tablecloth and soak 90min, dry at soaking latter 85 DEG C.Measure its anti-pilling property, bioassay standard is GB/T4802.2-1997.The bioassay standard of Escherichia coli inhibiting rate is FZ/T73023-2006, and result is as follows.
