The most common process for producing these buttons involves using a fiber optic machine to whiten the inner circumference of the button before spraying or dyeing it. This method requires individual button processing, resulting in low production efficiency and high costs. Therefore, developing a process for producing these buttons more suitable for mass production is crucial. Summary of the Invention

[0007] The above-mentioned color changing treatment step and post-treatment step both include a temperature raising and holding process;

[0010] The color-changing treatment liquid comprises water, hydrogen peroxide, sodium dihydrogen phosphate, ethylenediaminetetraacetic acid and a penetrant;

[0011] The components of the post-treatment liquid include water, sodium chloride, a penetrant, disodium hydrogen phosphate and sodium dihydrogen phosphate.

[0012] Preferably, the components of the color-changing treatment liquid include, by weight: 135 to 240 parts of water, 15 to 60 parts of hydrogen peroxide, 3 to 5 parts of sodium dihydrogen phosphate, 1 to 5 parts of ethylenediaminetetraacetic acid and 0.5 to 2 parts of a penetrant.

Furthermore, the process is a mass production process, eliminating the need for individual color-contrasting treatments on individual buttons. This results in higher production efficiency and lower costs, and has promising application prospects in the mass production of contrasting ox horn buttons. BRIEF DESCRIPTION OF THE DRAWINGS

[0092] Effect comparison

[0093] The horn buttons prepared in Examples 1 to 3 of the present invention and Comparative Examples 1 to 2 were compared and observed, and the results were as follows:

[0096] By comparing Comparative Example 2 with Example 2, it can be seen that the horn buttons that have not been treated with the post-treatment liquid will continue to discolor, resulting in unclear boundaries and extremely inconsistent effects.

[0097] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
