Performance Test

[0120] 1. Stability of enzyme preparation particles and softener preparation particles: the detergent tablets were placed in a test environment with temperature of (25?2? C.) and humidity of (40?5)%, kept for 48 hours, then picked up by hand, turned over, and rubbed properly, while observing whether the enzyme preparation particles and the softener preparation particles on the detergent tablets fall off. The results are shown in Table 3.

[0121] 2. Humidity resistance stability: two detergent tablets were stacked and placed in a test environment with a temperature of (25?2? C.) and humidity of (85?5)% for 24 h, and then the two detergent tablets were separated, while observing whether there was any adhesion, divided into no adhesion, slight adhesion and obvious adhesion, between tablets. The results are shown in Table 3.

[0122] 3. Detergency test: the test was performed according to the evaluation method in GB/T 13174-2021 Determination of Detergency and cycle of washing property for laundry detergents in combination with the evaluation standard of QB/T 1224-2012 Liquid Detergents for fabric, with a test concentration of the standard laundry detergent of 0.2%, and a test concentration of the sample of 0.013% (the test concentration was 1/15 of the standard laundry detergent).

3.1 Whiteness Measurement:

[0123] JB-01 stained cloth, JB-02 stained cloth and JB-03 stained cloth were cut into a size of 6 cm*6 cm, and were classified into six groups each having a similar blackness. Each group of the test cloths was used for testing the performance of a same sample.

[0124] Whiteness values before and after washing were read by using a whiteness meter one by one at 457 nm. Two points were selected on both sides of the test cloths before washing (the two points on each side were center symmetrical to each other) and measured in terms of whiteness values, in which an average of four measurements was defined as whiteness F1 of the test cloth before washing. Two points were selected on both sides of the test cloths after washing (the two points on each side were center symmetrical to each other) and measured in terms of whiteness values, in which an average of four measurements was defined as whiteness F2 of the test cloth before washing.

[0125] Whiteness difference (F2-F1) of each test cloth before and after washing was calculated by one-to-one correspondence, and a detergency of each group of the test cloths was calculated.

[0126] Calculation was conducted based on different kinds of the test cloths, and a detergency R and detergency ratio P achieved by a detergent on individual stained cloths were determined as follow.

3.2 Calculation of Detergency Value of a Stained Cloth

[0127] The detergency value Ri=?F2i?F1i)/n;

[0128] where:

[0129] iType i.sup.th stained test cloth;

[0130] F1ispectral reflectance of the type i.sup.th stained test cloth before washing, %;

[0131] F2ispectral reflectance of the type i.sup.th stained test cloth after washing, %;

[0132] neffective content of each group of stained test cloth.

[0133] One decimal place was kept for the results.

3.3 Calculation of Detergency Ratio of Stained Cloths

[0134] The detergency ratio Pi=R3i/R0i of a relative standard laundry detergent on the type i.sup.th stained cloth;

[0135] where:

[0136] R0idetergency value of a standard laundry detergent, %;

[0137] R3idetergency value for the sample.

[0138] One decimal place was kept for the results.

3.4 Determination of Detergency of a Detergent

[0139] When Pi?1.0, it is determined that the detergency of the sample to the type i.sup.th stained cloth is equal to or better than that of the standard laundry detergent, which is briefly referred to as qualified detergency for the type i.sup.th stained cloth; and

[0140] When Pi<1.0, it is determined that the detergency of the sample to the type i.sup.th stained cloth is inferior to that of the standard laundry detergent, which is briefly referred to as unqualified detergency for the type i.sup.th stained cloth.

[0141] The results are shown in Table 4.

[0142] 4. Antistatic property test: according to QB/T 4535-2013 Fabric softener standard, the anti-static property of the detergent tablets was tested, with a logarithm difference of surface specific resistances ?lg?.sub.s?2.5 being determined as qualified. The results are shown in Table 4. Table 3 Test results of particle stability and moisture resistance of detergent tablets prepared in Examples and Comparative Examples

[0143] It can be seen from the data in Table 4 that, with the increase of the content of the enzyme preparation, the detergency rate and, in turn, detergency performance of JB-01, JB-02 and JB-03 stained cloths increase gradually. In the Comparative Example 2, the content of enzyme preparation is large (70 kg), but the improvement in detergency is not obvious compared with that in Example 8 (the content of the enzyme preparation is 50 kg). When the added amount of the enzyme preparation is within the range of 0.1-50 kg, the detergency will increase significantly with the increase of the content of the enzyme preparation, especially for JB-02 stained cloth with more protein stains, for which the content of the enzyme preparation has a significant impact on the detergency.

[0144] In the Comparative Example 3 in which the enzyme preparation is added by preparing into a liquid and then sprayed onto the solid detergent tablets, the detergency rate for JB-02 dirty cloth is only 2.52, which, however, is 3.95 for JB-02 dirty cloth in Example 1 with the same enzyme preparation content. It can be seen that, the detergency rate is much lower than that of the detergent tablets with granular enzyme preparation. This is because the exposed liquid enzyme preparation is easily affected by the environmental temperature and humidity, thus affecting the detergency. In Comparative Example 4 in which the enzyme preparation in liquid form is directly mixed with other components of the detergent tablets, dried and shaped, the detergency rate for JB-02 dirty cloth is only 2.21, which, however, is 3.95 for JB-02 dirty cloth in Example 1 with the same enzyme preparation content. It can be seen that, the detergency is much lower than that of the detergent tablets using particular enzyme preparation. This is because directly incorporating the liquid enzyme preparation into the detergent tablets and the drying and shaping processes of the detergent tablets will inactivate some of the enzymes, thus impairing the detergency of the obtained detergent tablets.

[0145] In Comparative Examples 3-4 incorporating the enzyme preparation in liquid form, the stability test shows obvious adhesion in the 24 h and 48 h moisture resistance stability. The detergent tablets in Examples 1-8 show good stability.

[0146] It can be seen from the data in Table 4 that, with the increase of the content of the softener preparation, the antistatic performance of the fabric washed with the detergent tablets gradually increases. In the Comparative Example 6, the amount of softener particles is large (70 kg), but the antistatic performance is not significantly improved compared with that Example 7 added with 50 kg softener preparation.

[0147] In Comparative Example 7 in which the softener is sprayed on the semi-solid detergent tablets in liquid form, it can be seen from the data in Table 4 that the antistatic performance of the fabric washed with the detergent tablets of Comparison Example 7 is only 2.0. In addition, the detergent tablets in proportion 7 has a significantly weaker detergency than that of the detergent tablets containing the same amount of softener preparation in Example 1. In the Comparative Example 8 in which the softener is directly added into the detergent tablets with other ingredients in liquid form, it can be seen from the data in Table 4 that the antistatic performance of the fabric washed with the detergent tablets of Comparison Example 8 is only 2.0, which is unqualified. In addition, the detergency of the detergent tablets in Comparison Example 8 is significantly lower than that of the detergent tablets in Example 1 with the same amount of softener preparation. This is because the surfactant used in examples of the present application is anionic and non-ionic surfactant, and the softener as used contains cationic surfactant. Incorporating the softener preparation by spraying or directly mixing with other components of the detergent tablets will lead to a situation where the softener directly contacts the surfactant, and thus, the cationic surfactant and the anionic surfactant will be precipitated due to a electrostatic adsorption therebetween, weakening the efficacy of the two surfactants. In Example 1, owing to high molecular weight of polyethylene glycol/polypropylene glycol, the polyethylene glycol/polypropylene glycol and the cationic softener components encapsulated by them were slowly dissolved, and thus a mutual influence caused by precipitation due to electrostatic adsorption with strong anion detergent components in the first washing procedure can be avoided. After the tablets containing anionic detergent ingredients and the immobilized enzyme preparations were dissolved to wash clothes, the polyethylene glycol/polypropylene glycol and the encapsulated cationic softener ingredients begin to be dissolved in a rinsing procedure and release the cationic softener ingredients to contact the clothes. It can not only neutralize residual anionic detergent on clothes in time, but also make clothes cleaned by the detergent quickly repaired by the softener. It can really achieve the effect of washing, cleaning, protecting and softening clothes.

[0148] For the Comparative Examples 7-8 in which the softener preparation is incorporated in liquid form, obvious adhesion was observed in the 24 h and 48 h moisture resistance stability. In Comparative Example 9, no foaming agent was added, the overall structure of the detergent tablets was relatively compact and not loose enough, suffering from falling off of a large number of enzyme preparation particles and softener particles. Compared with Example 5 containing foaming agent but having the same composition, the detergency and antistatic properties are much weaker. This is because the foaming agent can loosen the internal structure of a slurry, so that the molecular chain of the water-soluble polymer forming the film can be easily broken or untied in the slurry containing water, so that the addition of auxiliary ingredients in the detergent tablet composition will not affect the stability and falling off property of the washing particle composition and the solid phase softener preparation.

[0149] In Comparative Example 10, the enzyme preparation particles and the softener preparation particles are directly mixed with other components of the detergent tablet to prepare the detergent tablet in which the enzyme preparation particles and the softener preparation particles are completely embedded. The components of the detergent tablet in Comparative Example 10 are identical to those in the example 5, but the difference is only in the position of the enzyme preparation particles and the softener preparation particles in the detergent tablets. In Example 5, the particles were embedded on the detergent tablets, while in Comparative Example 10, the particles were embedded evenly in the detergent tablets. It can be seen from the results of detergency and anti-static performance tests in Table 4 that, the detergent tablets in Comparative Example 10 has poor detergency and anti-static performance. The reason lies in that, providing enzyme preparation particles and softener preparation particles on the surface of the detergent tablet can make the particles contact with water earlier and dissolve quickly, which can quickly play its detergent effect and anti-static effect. In Comparative Example 10, the particles are evenly embedded in the detergent tablets. Therefore, the enzyme preparation particles and the softener preparation particles will be released only after the detergent tablets are completely dissolved, and then contact with water to serve their detergent and anti-static effects. In the fast washing mode of the washing machine, providing enzyme preparation particles and softener preparation particles inserted on the detergent tablets achieved more obvious advantages.
