Background technology
The material of sheet mostly is cotton, after a number of uses, and in long-time unwashed situation, sheet can grow a certain amount of bacterium, and wherein Escherichia coli are exactly a very large harm.Grow in a large number if Escherichia coli obtain, human body can be caused to produce some diseases.Equally, the amount reproduction of staphylococcus aureus, also can increase the ill risk of people.When arranging sheet, allowing sheet possess stronger significant suppression staphylococcus aureus and colibacillary effect, the probability that people are ill can be reduced.The current kind of finishing agent is more, in these finishing agents, the finishing agent of these two kinds of pathogenic bacteria can be suppressed significantly also less, need us and continues research and development.
Summary of the invention
The technical problem solved: common sheet does not have the effect suppressing Escherichia coli and staphylococcus aureus, can increase the risk of people after Long-Time Service.
Technical scheme: the invention discloses a kind of antibacterial sheet finishing agent, antibacterial sheet finishing agent is made up of according to weight ratio following composition: Dicalcium Phosphate is 3 ~ 7 parts, diatomite powder is 2 ~ 3 parts, titania powder is 1 ~ 2 part, zinc silicate is 3 ~ 5 parts, fatty alcohol-polyoxyethylene ether carboxylic acid sodium is 6 ~ 9 parts, diethylene glycol (DEG) is 3 ~ 5 parts, magnesium bicarbonate is 2 ~ 4 parts, water is 245 ~ 265 parts.
A preparation method for antibacterial sheet finishing agent, preparation method comprises the following steps: water temperature in finishing agent reactor heating jacket is adjusted to 62 DEG C ~ 68 DEG C by (1); (2) in question response still heating jacket after water temperature stability, in reactor, drop into water is 245 ~ 265 parts, and stir with paddle, speed of agitator is 200rpm, adds that fatty alcohol-polyoxyethylene ether carboxylic acid sodium is 6 ~ 9 parts, diethylene glycol (DEG) is 3 ~ 5 parts during stirring, stirs; (3) in reactor, add that Dicalcium Phosphate is 3 ~ 7 parts, diatomite powder is 2 ~ 3 parts, titania powder is 1 ~ 2 part, zinc silicate is 3 ~ 5 parts, magnesium bicarbonate is 2 ~ 4 parts again, high-speed stirred is carried out again with paddle, speed of agitator is 400rpm, till stirring; (4) finishing agent after stirring is cooled naturally, obtain antibacterial finishing agent.
Described fatty alcohol-polyoxyethylene ether carboxylic acid sodium is preferably 9 parts.Described Dicalcium Phosphate order number is preferably 400 orders.Described titania powder is preferably 2 parts.
Beneficial effect: by the sheet of pure-cotton fabric after finishing agent of the present invention arranges, the Escherichia coli inhibiting rate of sheet is 74% to 78%, and the inhibiting rate of staphylococcus aureus is 81% to 87%.
Detailed description of the invention
Embodiment 1
(1) water temperature in finishing agent reactor heating jacket is adjusted to 68 DEG C; (2) in question response still heating jacket after water temperature stability, in reactor, drop into water is 245kg, and stir with paddle, speed of agitator is 200rpm, adds that fatty alcohol-polyoxyethylene ether carboxylic acid sodium is 6kg, diethylene glycol (DEG) is 5kg during stirring, stirs; (3) in reactor, add that 400 object Dicalcium Phosphate are 7kg, diatomite powder is 2kg, titania powder is 2kg, zinc silicate is 3kg, magnesium bicarbonate is 4kg again, high-speed stirred is carried out again with paddle, speed of agitator is 400rpm, till stirring; (4) finishing agent after stirring is cooled naturally, obtain antibacterial finishing agent.
Embodiment 2
(1) water temperature in finishing agent reactor heating jacket is adjusted to 64 DEG C; (2) in question response still heating jacket after water temperature stability, in reactor, drop into water is 255kg, and stir with paddle, speed of agitator is 200rpm, adds that fatty alcohol-polyoxyethylene ether carboxylic acid sodium is 7kg, diethylene glycol (DEG) is 3kg during stirring, stirs; (3) in reactor, add that 400 object Dicalcium Phosphate are 3kg, diatomite powder is 3kg, titania powder is 2kg, zinc silicate is 4kg, magnesium bicarbonate is 2kg again, high-speed stirred is carried out again with paddle, speed of agitator is 400rpm, till stirring; (4) finishing agent after stirring is cooled naturally, obtain antibacterial finishing agent.
Embodiment 3
(1) water temperature in finishing agent reactor heating jacket is adjusted to 62 DEG C; (2) in question response still heating jacket after water temperature stability, in reactor, drop into water is 265kg, and stir with paddle, speed of agitator is 200rpm, adds that fatty alcohol-polyoxyethylene ether carboxylic acid sodium is 9kg, diethylene glycol (DEG) is 4kg during stirring, stirs; (3) in reactor, add that 400 object Dicalcium Phosphate are 5kg, diatomite powder is 2kg, titania powder is 1kg, zinc silicate is 5kg, magnesium bicarbonate is 3kg again, high-speed stirred is carried out again with paddle, speed of agitator is 400rpm, till stirring; (4) finishing agent after stirring is cooled naturally, obtain antibacterial finishing agent.
Get textile sheet, soak 2h with the finishing agent of embodiment 1, embodiment 2, embodiment 3, naturally dry after soaking.Measure the bacteriostasis rate of the sheet after arranging.Bacterial classification is Escherichia coli and staphylococcus aureus, and bioassay standard is FZ/T73023-2006, and test result is as follows.
