Description
Technical field
The invention belongs to household chemicals manufacture field, and in particular to a kind of antibacterial softening laundry liquid and preparation method thereof.
Background technology
Liquid detergent is a kind of detergent compositions of liquid, and its operation principle is same with traditional washing powder and soap kind, effectively into
It is all surfactant to divide.For, in the product of clothes washing, washing powder accounts for main status always.But, liquid detergent master
Composition is wanted to be nonionic surfactant, dirt-removing power is strong, and can play cleaning function, decontamination inside deep enough clothes fiber
It is more thorough.Liquid detergent compares washing powder, with more advantages.Washing powder can not be completely dissolved in use, residue
Clothing damage is easily caused, and is difficult rinsing；And liquid detergent can be completely dissolved and dissolution velocity fast, easily float washable, will not
Injure skin and clothing.Washing powder is generally alkaline, larger to skin irritatin and injury；And liquid detergent pH value partial neutral,
Formula does not gently hurt hands.Liquid detergent is easy to add various active ingredients, increases its feature, such as softness, gloss, brighten, it is degerming
With effect of lasting lasting.The waste liquid that washing powder is produced is in difficult (the particularly branched alkyl benzene sulphonate of nature degraded
Sodium), water pollution is caused, very big destruction is caused to ecology；And liquid detergent then relative degraded relatively completely, environment cause it is bad compared with
It is little.As liquid detergent has many advantages, therefore, the growth of liquid detergent industry is also more swift and violent.The liquid detergent city of China
Increased with average annual 27.2% speed, 3 years compound has grown beyond 100%.Meanwhile, the average annual increasing in washing powder market
Speed is only 2.2%.Domestic liquid detergent will reach the 19% of whole laundry detergents market in 2010, be reached in 2015 afterwards
30%.And in the U.S., the market share of liquid detergent has been over washing powder, accounting reaches more than 80%, has greatly replacement laundry
The trend of powder.
As liquid detergent is more convenient for increasing functional components compared to washing powder so that liquid detergent possesses work(more in all directions
Effect.The liquid detergent such as existing antibacterial, net white, soft, color drift, low alveolitoid on the market, species are various, and the rinsing of suitable difference clothings need to
Ask.The liquid detergent demand that liquid detergent with antibiotic property becomes in recent years is popular.With the continuous lifting of people's living standard, more
Carry out more consumers for the demand of laundry, be not only embodied on higher detergency ability, for the removal of pathogenic bacteria
Pay attention to further.Existing patent and Patent Application Publication also relates to the formula and processing technology of antimicrobial laundry liquid at present.As sent out
Bright Patent Application Publication " antibiotic property liquid detergent " (number of patent application：201510846429.7) disclose a kind of antibiotic property laundry
Liquid, is characterized in that and with the addition of the composite mesoporous antiseptic of high activity cerium silver, by mesoporous material and the group of antibacterial activity material
Close so that antibacterial activity material can be evenly dispersed in needing degerming environment, bacterium on clothing is killed so as to reach
Effect；A kind of application for a patent for invention document " antimicrobial laundry liquid " (number of patent application：201410451184.3) disclose a kind of anti-
Bacterium liquid detergent, includes nano-TiO2High effect nontoxic antiseptic, good anti-bacterial effect；Application for a patent for invention document " receive by a kind of addition
Strong disinfecting and durable antibiotic liquid detergent of meter Yin and preparation method thereof " (number of patent application：201510810227.7) disclose
A kind of strong disinfecting and durable antibiotic liquid detergent and preparation method thereof of addition Nano Silver, the liquid detergent by soapberry extract,
Carrying nano silver zeolite antibacterial agent, shitosan-Nano silver solution and Kathon CG etc. are constituted, via series of steps systems such as stirring, heating
It is standby to form, with strong bactericidal and persistently antibacterial double effectses.
With the application and the popularization of washing machine of synthetic detergent, fabric etc. is effectively washed, you can reach good
Good cleannes, but due to during washing fabric affected by mechanical force, Jing after many times are washed, fabric has significantly fabric in addition
Harsh feeling.Underwear, particularly sheet, towel such as bafta can make skin have uncomfortable sensation when in use.Synthetic fibers
As polarity is fullyed recover from an illness good insulating, and the factor that rubs is larger, dress or when be also easy to produce electrostatic, make skin not feel well.Therefore, need
To make that fabric sofetening is fluffy, antistatic, good hand touch by antistatic treatment being carried out to fabric, reduce the mutual adhesion of fabric, and keep away
Exempt from corrugation.Can be by adding antistatic composition in detergent, to reach effect of submissive clothing.
Carboxymethyl chitosan is a kind of water-solubility chitosan derivative, has numerous characteristics, and such as antibiotic property is strong, with fresh-keeping work
With being a kind of polyampholyte, have various applications at the aspect such as cosmetics, fresh-keeping, medical, and Recent study obtains more
One of chitosan derivatives.The silver carboxymethyl chitosan being prepared from silver complexing using carboxymethyl chitosan, stability are strong,
And hydrophily compares shitosan more preferably, can be used to prepare the cosmetics of everyday use for requiring that there are biocidal efficacies.
The disclosure of background above technology contents is only used for inventive concept and the technical scheme for aiding in understanding the present invention, and which is not
The prior art of present patent application is necessarily belonged to, shows the applying date of the above in present patent application there is no tangible proof
In the case of disclosed, above-mentioned background technology should not be taken to the novelty and creativeness for evaluating the application.
