Abstract
The invention discloses a kind of antibacterial finishing agent of real silk fabric, modified polyorganosiloxane, carboxymethyl cellulose and chitin are included.Wherein modified polyorganosiloxane is modified jointly by DTAC and Polyhaxemethylenguanidine Hydrochloride.The finishing agent good anti-bacterial effect, while tack is good.Real silk fabric can still keep soft feel and good gas permeability, and can still keep preferable antibiotic property after repeatedly washing after antibacterial finishing agent arrangement.
Description
Technical field：
The present invention relates to field of textiles, more particularly to a kind of antibacterial finishing agent of real silk fabric.
Background technology
With the continuous improvement of people's living standards, to the quality requirements of daily necessities also more and more higher, especially to spinning
The requirement of fabric quality.Textile is not required nothing more than with higher aesthetics, simultaneously for textile to healthy influence
Also there are more concerns.The antibiotic finish of textile starts from the forties in last century, and that has applied at present is quite varied, covers each
Plant fabric.Final finishing processing is carried out to fabric using antibacterial finishing agent, is the effective means for making fabric possess antibacterial ability.
It is mainly organic antiseptic using relatively broad antibacterial finishing agent at present, this kind of antibacterial finishing agent can be with wide spectrum
It is antibacterial, bacterial resistance occurred, highly effective and safe will not be made, be widely used in all kinds of textiles.But, such antibacterial finishing agent
There are problems that poor durability, stripping quantity have to be solved.In recent years, inorganic antibacterial finishing agent and natural products antibacterial
Finishing agent rises gradually, and progress attracts people's attention.But the ununified examination criteria of this kind of antibacterial finishing agent, it is difficult to objectively
Evaluate the antibacterial effect that it is applied to after fabric.
Real silk fabric is typically used for directly personal clothing and used due to the texture of its soft comfortable.But silk is knitted
Thing is protein fibre in itself, easily causes bacteria breed, so as to influence people's healthy.Therefore, real silk fabric is entered
Row antibiotic finish is the effective way for improving fabric commercial value.Chinese patent CN201510480817.8 discloses a kind of new
Natural antibacterial finishing agent and preparation method thereof, described natural antibacterial finishing agent includes 3-6 parts of chitosan, 4-9 parts of Chinese juniper oil, sweet
Careless water extract 3-7 parts, 2-5 parts of akebi water extract, 3-5 parts of Siberian elm brak ethanol extract, 3-6 parts of osmanthus fourth ethanol extract, bay
2-4 parts of acyl diethanol amine, 3-7 parts of DDAC, 5-10 parts of glycerine, 200-300 parts of water.Described preparation method
Carry, filter including hot dipping, vacuum film is dried, mixing, the natural antibacterial finishing agent of preparation is to Escherichia coli and golden yellow grape
Coccus has good inhibitory action.
The content of the invention
It is an object of the invention to provide a kind of antibacterial finishing agent of real silk fabric, the finishing agent good anti-bacterial effect, simultaneously
Tack is good.Real silk fabric can still keep soft feel and good gas permeability after antibacterial finishing agent arrangement, and
And can still keep preferable antibiotic property after repeatedly washing.
To achieve the above object, the present invention uses following technical scheme：
A kind of antibacterial finishing agent of real silk fabric, is prepared from by following steps：
(1) DTAC is mixed with hexamethyldisiloxane, be dissolved in organic solution, in KBr
Catalysis under, maintain temperature sustained response 2-4h at 80-100 DEG C, add appropriate emulsifying agent, be stirred vigorously and prepare modified monomer
Emulsion；
(2) hexamethyldisiloxane and hydroxyl-terminated injecting two methyl siloxane are added into modified monomer emulsion, control temperature exists
80-100 DEG C, add under base catalyst after reaction 2h, addition propane diols diglycidyl ether, after stirring 60-90min, salt is added dropwise
Terminating reaction after sour polyhexamethylene guanide, reaction 4h, regulation pH to neutrality adds water and is stirred vigorously uniformly, true using batch (-type)
Empty way of distillation vacuum distillation, removes organic solvent and lower-molecular substance, both obtains modified polyorganosiloxane；
(3) one step up in sequentially add carboxymethyl cellulose, chitin in obtained modified polyorganosiloxane emulsion, fully
After stirring, antibacterial finishing agent needed for both obtaining.
It is preferred that, the molar ratio of DTAC and hexamethyldisiloxane is 1 in the step 1：
(1.5-2)。
It is preferred that, organic solution is one kind in ethanol, ethyl acetate or methanol in the step 1.
It is preferred that, hexamethyldisiloxane and dialkyl polydimethylsiloxane and dodecyl in step 1 in the step 2
The molar ratio of trimethyl ammonium chloride is 1：2：1.
It is preferred that, the molar ratio of the KBr and DTAC is (0.6-1):1.
It is preferred that, the input ratio of the hydroxyl-terminated injecting two methyl siloxane and water is 0.01-0.1mol/L.
It is preferred that, the base catalyst is one in TMAH, sodium hydroxide or tetrabutylammonium hydroxide phosphorus
Kind.
It is preferred that, the hydroxyl-terminated injecting two methyl siloxane, propane diols diglycidyl ether and Polyhaxemethylenguanidine Hydrochloride
Molar ratio be 1：(0.5-0.8):(1.2-1.5).
It is preferred that, the ratio of carboxymethyl cellulose and the modified polyorganosiloxane emulsion is 1-2g/L.
It is preferred that, the ratio of chitin and the modified polyorganosiloxane emulsion is 0.5-0.8g/L.
Wherein, the consumption of the selection of emulsifying agent and consumption and base catalyst is that those skilled in the art can be by feelings
Condition carries out selection.
The invention has the advantages that, the present invention utilizes dodecyl three using modified polyorganosiloxane as main component
The antibiotic property of ammonio methacrylate and Polyhaxemethylenguanidine Hydrochloride is simultaneously grafted with polysiloxanes, can firmly be attached to silkworm
The surface of silk fabrics, water-wash resistance is strong.Modified polyorganosiloxane is supported on silk fabric, can't influence fabric pliability and
Gas permeability, can make silk fabric maintain preferable feel.The antibacterial finishing agent good anti-bacterial effect, persistence is strong, by multiple
Fabric can be still set to keep preferable anti-microbial property after washing.
