[0193] The products of Examples 1 to 3 and Comparative Examples 1 to 12 were subjected to conventional performance tests to test the easy-to-clean performance and anti-pilling performance. The test results are shown in Table 1.

[0194] Test method: divide the products into groups, 100 in each group, rub each group of tested products 50 times, and test the number of pilling; immerse the products in the oil stains, take them out, place them at room temperature for 24 hours, then apply wiping force to wipe the oil stains until the products are clean, and test the wiping force. The smaller the wiping force, the cleaner it is.

[0195] At the same time, wash the product once in 70℃ water and then 2 The product was exposed to the sun for 12 hours under a radiation intensity of 375 nm (wavelength). The above is a cycle test, which was conducted 10 times to test the product's resistance to high temperature washing and exposure stability. At the same time, the product was immersed in acetone solvent for 48 hours to test the product's solvent resistance.

[0196] Table 1 Product performance test results of Examples 1 to 3 and Comparative Examples 1 to 12:

[0197]

[0198] It can be seen from Comparative Examples 1-12 and Examples 1-3 that the product of Example 3 has excellent anti-pilling and easy-to-clean performance, and the two performances can be improved in a coordinated manner, and the product has significant stability effects under high temperature washing and exposure conditions and solvent resistance conditions;

[0199] The present invention does not add a nepheline syenite doped auxiliary agent, nor does it add one of the modified stabilizing agents. The performance stability of the product shows a significant trend of deterioration. The two are coordinated and synergistic, and the performance effect of the product is most significant.

[0200] The performance of the products tended to deteriorate when the nepheline syenite-doped blending agent was not added in the preparation of the blending agent, the blending agent was not treated with a blending liquid, the blending liquid preparation method was different, and the modified filler liquid was not added in the preparation of the nepheline syenite-doped blending agent.

[0201] The performance of the products of the additives doped with nepheline syenite obtained by different methods all tend to deteriorate, and only the additive doped with nepheline syenite obtained by the method of the present invention has the most significant product performance effect;

[0202] In the preparation of the additive doped with nepheline syenite, no modified filler liquid and no nepheline syenite as an additive were added. The performance of the product deteriorated significantly in the preparation of the additive doped with nepheline syenite.

[0203] The performance of the products tended to deteriorate when magnesium borate whisker liquid was not added in the preparation of the modified stabilizer, magnesium borate whisker agent was not added in the preparation of the magnesium borate whisker liquid, hydroxyapatite and sodium citrate solution were not added in the preparation of the magnesium borate whisker agent and deionized water was used instead, magnesium borate whisker and nano-silica sol were not added in the preparation of the magnesium borate whisker agent, stabilizing liquid was not added in the preparation of the modified stabilizer, and preheated nano-calcite powder was not added to the stabilizing liquid.

[0204] The modified stabilizer prepared by combining the magnesium borate whisker agent and the stabilizer liquid obtained by the specific method of the present invention has the most significant performance effect of the product, and other methods are not as significant as the effect of the present invention.

[0205] The present invention further explores the product performance through the preparation of modified filler liquid.

[0206] Experimental Example 1:

[0207] The only difference from Example 3 is that no composite material is added to the modified filler liquid.

[0208] Experimental Example 2:

[0209] The only difference from Example 3 is that no nano titanium dioxide is added to the composite material.

[0210] Experimental Example 3:

[0211] The only difference from Example 3 is that no carbon nanotubes are added to the composite material.

[0212] Experimental Example 4:

[0213] The only difference from Example 3 is that no yttrium nitrate solution is added to the modified filler liquid.

[0214] Experimental Example 5:

[0215] The only difference from Example 3 is that no chitosan solution is added to the modified filler liquid.

[0216] The products of Experimental Examples 1 to 5 were subjected to the above-mentioned performance tests, and the easy-to-clean performance and anti-pilling performance were tested. The test results are shown in Table 2.

[0217] Table 2 Product performance test results of Experimental Examples 1 to 5:

[0218]

[0219] It can be seen from Experimental Examples 1-5 that when no composite material is added to the modified filler liquid, the performance of the product changes. Among the composition and preparation factors of the modified filler liquid, the performance deterioration is the most obvious. The second is that no nano-titanium dioxide and no carbon nanotubes are added to the composite material, and the performance of the product also shows a more obvious deterioration trend. In addition, when no yttrium nitrate solution and no chitosan solution are added to the modified filler liquid, the performance of the product has a deterioration trend. The preparation methods using other methods to replace the modified filler liquid are not as significant as the effect of the present invention. The composition and preparation conditions of the modified filler liquid of the present invention are unique.
