Example 5 Performance testing
The detergent for cleaning silk and wool of examples 1-4 and comparative examples 1-3 were tested for detergency, softness and anti-staining property, respectively, according to the following methods:
(1) and testing detergency: the test is carried out according to the detergency determination method of QB/T1224-2012, and the decontamination ratio of the carbon black soiled cloth JB01, protein soiled cloth JB02 and sebum soiled cloth JB03 decontamination cloth test is obtained.
(2) And flexibility test: randomly selecting 10 persons, carrying out softness blind test on seven groups of washed and naturally dried wool fabric samples in a hand feeling touch mode, carrying out evaluation and scoring, wherein the scoring range is 1-5 points, the scoring is best at 5 points, the scoring is worst at 1 point, and the average value is taken after the lowest point and the highest point are removed.
The test results are shown in table 1:
TABLE 1
| Carbon black stained cloth JB01 | Protein stain cloth JB02 | Sebum stain cloth JB03 | Softness score | |
| Example 1 | 1.07 | 1.22 | 1.09 | 4 |
| Example 2 | 1.1 | 1.25 | 1.10 | 4.5 |
| Example 3 | 1.05 | 1.18 | 1.06 | 3.5 |
| Example 4 | 1.08 | 1.24 | 1.09 | 3.5 |
| Comparative example 1 | 1.01 | 1.10 | 1.02 | 2.5 |
| Comparative example 2 | 1.01 | 1.08 | 1.04 | 2.5 |
| Comparative example 3 | 1.02 | 1.1 | 1.03 | 3.0 |
As can be seen from Table 1 above, the detergents of examples 1 to 4 are significantly superior in detergency to the detergents of comparative examples 1 to 3. The fatty amine polyoxyethylene ether diquaternary ammonium salt has obvious detergency effect on the JB03 sebum spin dirty cloth, and proves that the degreasing capability of the cloth is strong; the softness effect of the example 2 is better than that of the example 1, the softness effect of the example 4 is not much different from that of the example 3, and the decontamination effect of the invention is related to the effective concentration in the detergent, namely, the higher the water content is, the smaller the effective concentration in the unit volume is, and the lower the decontamination power is; comparative example 1 was slightly less effective than comparative example 2.
(3) And anti-staining test: seven pieces of red sample cloth with the same size are cut, and single fiber lining test standard white cloth with the same size is attached to the front surface of each red sample cloth. The adhesive white cloth for the JIS L0803 dyeing fastness test is selected, and the components are silk and polyurethane multi-fiber blended fabric. Then rinsing in washing machine for 15 min. The white cloth was taken out and the staining degree of the white cloth was compared.
The staining degree is obtained by the staining condition of the white cloth for the lining through a contrast dyeing fastness test: example 2 < example 1 < example 4 < example 3 < comparative example 2 < comparative example 1; in other words, the excellent anti-staining properties of the fimbriae are example 2 > example 1 > example 4 > example 3 > comparative example 2 > comparative example 1.
The above-described embodiments are preferred implementations of the present invention, and the present invention may be implemented in other ways without departing from the spirit of the present invention.
