(1) test method
1 hard water is prepared
16.70g calcium chloride and 20.37g magnesium chlorides are weighed, prepares 10.0L, as 2500mg/Kg hard water.Taken during use
It is 250mg/Kg hard water that 1.0L, which is rushed to 10.0L,.
The preparation of 2 standard liquid detergents
8 parts of alkyl benzene sulphonate (pressing actives basis), 4 parts of polyethoxylated fatty alcohols (average EO adds sum to be 9), ethyoxyl
Change 2 parts of sodium alkyl sulfate (pressing actives basis), 0.5 part of triethanolamine, 0.6 part of two citric acid monohydrate trisodiums, water surplus.Preparation side
Method：Various composition is sequentially added in a certain amount of water, while stirring and dissolving (heating if necessary), and it is molten with sodium hydroxide regulation
The pH value of liquid is 8.5-9.0, supplies water to 100%.
The measurement of 3 whiteness
By JB-1 soiled cottons, JB-2 soiled cottons, JB-3 soiled cottons are cut into 6cm*6cm size respectively, and category mixes into flat respectively
Six groups similar in equal blackness, every group of test piece is used for the performance test of a sample.
Test piece is stacked by same category, the front and rear whiteness value of washing is read one by one under 457nm with leucometer.It is white before washing
Degree respectively takes two points (answer Central Symmetry) at 2 points per one side with test piece tow sides, whiteness value is measured, with the flat of four measurements
Average washes preceding whiteness F1 for the test piece；Wash rear whiteness then respectively takes two points (should per 2 points of one side in the tow sides of test piece
Central Symmetry), whiteness value is measured, rear whiteness F2 is washed as the test piece using the average value of four measurements.
(3) decontamination decantation test
Decantation test is carried out in Terg-O-Tometer, first numbers agitator arm, work nest, decontamination bathtub one by one before measure
Fixed composition one " working cell ", and preheater apparatus is to stable a period of time at 30 DEG C ± 1 DEG C.It is hard with 250mg/kg during experiment
Sample is configured to 0.1% test solution by water (being used when should be preheated to about 30 DEG C in advance) respectively, and standard liquid detergent is configured to
0.2% test solution, each 1L are poured into corresponding decontamination cylinder, and bathtub is put into corresponding position and installs agitator arm,
Conditioning instrumentation makes decantation test temperature be maintained at 30 DEG C ± 1 DEG C, prepares measure.
The each group test piece for surveying whiteness is put into each bathtub respectively, starts stirring, and is kept stirring for speed 120r/min,
Washing process stops after continuing 20min.
Test piece in each decontamination bathtub is merged and poured into the interior bucket of rinsing device, it is drained, put rinsing device into, pour into
1500mL running water, closes the lid, and rotates lid upper handle, and (period should be such that interior bucket fully turns for stopping after making interior bucket rotation about 30s
It is dynamic, but need to avoid because rotate it is too fast caused by container washings spilling).The water after rinsing is bled off, adds 1500mL again certainly
Water, repeat second of rinsing.Washings are bled off, manual dehydration 15s (rotating speed about 1800r/min) is carried out to test piece.Take
The test piece gone out after the completion of rinsing, hang after drying after room temperature, whiteness F2 is measured by the method for soiled cotton whiteness measurement before washing.
In a manner of one-to-one, the whiteness calculated before and after each test piece is washed is poor (F2-F1), and to every group of test piece, divides
Detergency is not calculated.Calculated respectively according to different types of soiled cotton test piece, judge decontamination value R of the detergent on all kinds of soiled cottons and
Decontamination ratio P, method are as follows.
(4) calculating of soiled cotton decontamination value
The decontamination value (Ri) of certain soiled cotton is calculated by formula Ri=∑s (F2i-F1i)/n.
In formula：
I --- the i-th species soiled cotton test piece；
F1i --- preceding spectral reflectivity, % are washed in the i-th species soiled cotton test piece；
F2i --- rear spectral reflectivity, % are washed in the i-th species soiled cotton test piece；
N --- the effective content of every group of soiled cotton test piece.
As a result one decimal place is remained into.
(5) calculating of soiled cotton decontamination ratio
Relative standard's liquid detergent is calculated in the decontamination ratio (Pi) of the i-th species soiled cotton by Pi=R3i/R0i.
In formula：
The decontamination value of R0i --- standard liquid detergent, %；
The decontamination value of R3i --- sample, %.
As a result one decimal place is remained into.
(6) judgement of detergent detergency
As Pi >=1.0, then conclusion is judged for " sample is to i-th kind of soiled cotton detergency quite or better than standard liquid detergent ",
Referred to as " i-th kind of soiled cotton detergency is qualified "；
As Pi ＜ 1.0, then judge that conclusion is " sample is inferior to standard liquid detergent to i-th kind of soiled cotton detergency ", referred to as " the
I kind soiled cotton detergencies are unqualified ".
The embodiment of table 4 and comparative example detergency test result
Embodiments of the invention are the foregoing is only, are not intended to limit the scope of the invention, it is every to utilize this hair
The equivalent structure or equivalent flow conversion that bright description is made, or directly or indirectly it is used in other related technology necks
Domain, it is included within the scope of the present invention.
