1. treating dirty cloth: cutting the dirty cloth into small cloth pieces of 20 × 20mm for standby, wherein each group of test pieces is at least 2, and mixing and testing various test pieces.
2. The experimental steps are as follows: and (3) putting each group of test pieces for measuring whiteness into the prepared sample, slightly stirring to completely immerse the test pieces, and standing for 10 min. Combining the test pieces in each group of the waste liquid, draining, putting into 0.5L tap water, manually stirring clockwise for 30 times, changing water, and repeatedly rinsing for 3 times. The rinsing water was drained off and the test pieces were poured into a rinser and dehydrated manually for 15 seconds (rotation speed about 1800 rpm). And taking out the rinsed test piece, airing at room temperature, and testing the whiteness after washing.
The calculation method comprises the following steps:
measuring Lab value by using a color difference meter, and performing the following calculation processing according to the measured L, a and b values:
sample-L standard (if Δ L is positive, the sample is lighter than the standard; if Δ L is negative, the sample is darker than the standard)
A sample-a standard (if Δ a is positive, the sample is red than the standard, if Δ a is negative, the sample is green than the standard)
Sample b-L standard (if Δ b is positive, the sample is yellow compared to the standard, if Δ b is negative, the sample is blue compared to the standard)
△E＝[(△L)2+(△a)2+(△b)2]1/2
The following conclusions can be drawn according to the practical situation and the numerical calculation result of the color difference calculation formula:
the delta E is between 0 and 1, and the chromatic aberration is difficult to distinguish by naked eyes;
the delta E is between 1 and 2, and the color difference can be slightly detected by naked eyes;
the delta E is between 2 and 3, and the color difference between objects can be roughly distinguished by naked eyes;
the delta E is between 3.5 and 5, and the chromatic aberration can be obviously distinguished by naked eyes;
the delta E is more than 5, and the larger chromatic aberration can be regarded as two colors.
And (3) detection results:
a is standard protein stain cloth JB-02; b is blood stain cloth EMPA 111; c is blood stain cloth CS-01.
The delta E of the mixed blood stain cloth and the aged blood stain cloth are both more than 5, and each sample has better detergency performance, wherein the test data of examples 5, 10 and 16 are more prominent; the JB-02 protein stain cloth test results are closer, wherein example 22 performs better in JB-02. The comprehensive test result is basically consistent with the visual inspection result, and the washing effect is visible to naked eyes.
The soiled cloths in this test example were visually observed after washing, graded, and the first (whitest) graded samples after washing were selected as examples 5, 10, 16, and 22, respectively. The washed sewage has obvious difference, wherein the coconut oil acid has stronger neutralizing and washing capacity by potassium hydroxide, and the triethanolamine is used for neutralizing fatty acid and generally has stronger cleaning effect.
The invention has better removal effect on protein stains, particularly blood stains, and realizes unexpected effect.
Protein stains can be oxidized, denatured and solidified in the air, and can be firmly combined with fabrics when meeting high temperature, so that great difficulty is brought to decontamination treatment. The invention not only has better cleaning effect on fresh blood and egg white, but also has considerable removing effect on aged blood stains and standard protein stains.
