Summary of the invention
The invention mainly solves the technical problem of providing comfortable protective garments of a kind of antibacterial and preparation method thereof.
To achieve the above object, the technical solution adopted by the present invention is that:
A kind of preparation method of the comfortable protective garment of antibacterial, comprising the following steps:
(1) polyurethane or modified polyurethane are added to the water with revolving speed is 500-1500r/min stirring 15-25min, then plus
Entering silicone additives, oleoyl methyl sodium taurocholate, citric acid with revolving speed is that 500-1500r/min stirs 15-25min, is obtained
To finishing fluid；
(2) fabric is impregnated into finishing fluid 15-45min, the fabric after dipping is subjected to mangle, drying obtains antibacterial
Fabric；Antibacterial fabric is cut out, sew to get.
Preferably, the preparation method of the comfortable protective garment of a kind of antibacterial, comprising the following steps:
(1) 1-5kg polyurethane or modified polyurethane are added in 95-99kg water with revolving speed as 500-1500r/min stirring
15-25min adds 0.2-0.6kg silicone additives, 0.1-0.4kg oleoyl methyl sodium taurocholate, 0.05-0.15kg
Citric acid is that 500-1500r/min stirs 15-25min with revolving speed, obtains finishing fluid；
(2) fabric is impregnated into 15-45min in 10-30 times of fabric weight of finishing fluid, the fabric after dipping is rolled
Liquid, pick-up 50-65wt%, then 60-70 DEG C baking 2-6 minutes, 95-115 DEG C baking 1-4 minutes, finally in 30-
50 DEG C of drying 15-25h, obtain antibacterial fabric；Antibacterial fabric is cut out, sew to get.
The fabric is pure cotton grey fabric or polyester-cotton blend fabric or polyester fiber fabric or bamboo fibre fabric.
The dipping temperature is 30-50 DEG C.
The polyurethane is prepared by the following method: by 40-50 parts by weight polyether polyol temperature be 90-110 DEG C, pressure
It is to remove vacuum after 0.01-0.05MPa vacuum dehydration 1-5 hours, is cooled to 50-90 DEG C, 10-20 weight is added under nitrogen protection
Measure part 1, hexamethylene-diisocyanate keep temperature be 50-90 DEG C with revolving speed be 100-400r/min stirring 1.5-2.5h, then exist
Under nitrogen protection be added 0.2-0.8 parts by weight of octanoic acid stannous keep temperature be 50-90 DEG C with revolving speed be 100-400r/min stirring
1-2h, then be added 3-7 parts by weight diethylenetriamine keep temperature be 50-80 DEG C with revolving speed be 100-400r/min stirring 20-
30 minutes；Be eventually adding 4-10 parts by weight 1,4- butanediol keep temperature be 50-80 DEG C with revolving speed be 100-400r/min stirring
2-6h；Stop stirring, cool to 40-60 DEG C, is 0.01-0.05MPa vacuum defoamation 10-20 minutes in pressure, filtering, i.e.,
?.
With the continuous improvement of social progress and living standard, the health care consciousness of people is gradually increased.Especially some spies
Different clothes, insole, sheet etc. are easy to produce pollution and breed bacterium, so the fabric with antibacterial functions is exactly modern society
It is desirable.In order to cater to the needs in market, occur the clothes of certain healths at present, there is certain antibacterial function
Can, still, antibacterial functions are realized by drug ingedient contained in fabric, the binding force of fabric and drug compared with
Weak, stability is poor, wears no resistance, using over time or generating peculiar smell.
The modified polyurethane is prepared by the following method: by 40-50 parts by weight polyether polyol temperature be 90-110 DEG C,
Pressure is to remove vacuum after 0.01-0.05MPa vacuum dehydration 1-5 hours, is cooled to 50-90 DEG C, 10- is added under nitrogen protection
20 parts by weight 1, hexamethylene-diisocyanate keep temperature be 50-90 DEG C with revolving speed be 100-400r/min stirring 1.5-2.5h, so
The quaternized organic silicone oil of 0.5-1.5 parts by weight self-emulsifying type, 0.3-0.9 parts by weight polyhexamethylene is added under nitrogen protection afterwards
Biguanide hydrochloride, 0.2-0.8 parts by weight of octanoic acid stannous keep temperature be 50-90 DEG C with revolving speed be 100-400r/min stirring 1-
2h, then be added 3-7 parts by weight diethylenetriamine keep temperature be 50-80 DEG C with revolving speed be 100-400r/min stirring 20-30
Minute；Be eventually adding 4-10 parts by weight 1,4- butanediol keep temperature be 50-80 DEG C with revolving speed be 100-400r/min stirring 2-
6h；Stop stirring, cool to 40-60 DEG C, is 0.01-0.05MPa vacuum defoamation 10-20 minutes in pressure, filtering, i.e.,
?.
The silicone additives additive is organosilicon quaternary phosphonium salt and/or organosilicon quaternary ammonium salt.Further, described to have
