The preparation method includes the following steps: a) subjecting the button to alkali treatment to obtain an alkali-treated button; b) sequentially washing, drying, and surface-treating the alkali-treated button obtained in step a) to a treated button; c) adjusting the pH of the treated button obtained in step b) and then dyeing it, followed by drying to obtain a ring-textured button. Compared with the prior art, the preparation method provided by this invention uses specific process steps to achieve better overall interaction, forming a wood grain texture effect on the button surface, creating a raised and recessed texture effect similar to tree rings. It has the advantages of low energy consumption and low cost, and the prepared ring-textured buttons are not unique in shape. Furthermore, because a treatment solution is used for impregnation, a large number of buttons can be processed at once, resulting in high production efficiency.

Description

Technical Field

[0001] This invention relates to the field of garment accessories technology, and more specifically, to a ring-patterned button and its preparation method. Background Technology

[0002] Fruit-shaped buttons originate from the fruit of palm trees in Africa. The fruit is hard and, due to its ivory-like texture and color, is also known as ivory fruit. With a long history, this natural material not only offers the best value for money but also boasts beautiful patterns (like wood grain), high malleability, and a wide range of colors. As manufacturing processes have advanced, the types, materials, and techniques used for buttons have become more diverse, leading to higher demands for the surface finish of fruit-shaped buttons.

[0003] The natural patterns and textures of fruit are stunning; their smooth, varied patterns give products a unique beauty. Therefore, how to highlight the fruit texture effect and apply it to garment accessories such as buttons has become a research topic within the industry.

[0004] Currently, existing technologies generally employ laser technology, which includes: drawing a laser pattern, turning on the power, starting the laser machine, entering the laser machine control software, and starting the software control panel; placing the button in the designated position, and using the laser machine to laser-etch the raised and recessed textures onto each button one by one.

[0005] However, the buttons processed by laser technology have the following drawbacks: (1) Laser technology requires lasering one by one, which results in low processing efficiency, high energy consumption, and high cost; (2) Since lasering is based on the artwork, the product effect is uniform. Summary of the Invention

[0006] In view of this, the purpose of the present invention is to provide a ring-textured button and its preparation method. The preparation method provided by the present invention does not rely on laser but on a treatment liquid to form a wood-textured effect on the button surface, forming a raised texture effect similar to tree rings. It has the advantages of low energy consumption and low cost. Moreover, the ring-textured buttons prepared are not unique in shape. At the same time, since a large number of buttons can be processed at one time due to the use of a treatment liquid for impregnation, the production efficiency is high.

[0007] This invention provides a method for preparing a button with an annual ring texture, comprising the following steps:

[0008] a) The buttons to be processed are subjected to alkaline treatment to obtain alkaline-treated buttons;

[0009] b) The buttons obtained in step a) after alkali treatment are washed with water, dried and surface treated in sequence to obtain the treated buttons;

[0010] c) After adjusting the pH of the treated buttons obtained in step b), dye them and dry them to obtain buttons with annual ring texture.

[0011] Preferably, before the alkali treatment described in step a), the procedure further includes:

[0012] Place the buttons to be processed in an oven and dry them at 30℃~45℃ for 45h~50h.

[0015] Preferably, the pretreatment solution is composed of water and sodium hydroxide in a mass ratio of 100:(5-20).

[0016] Preferably, the washing and drying process in step b) specifically includes:

[0017] After alkali treatment, the buttons are repeatedly washed with water until the pH value is between 7 and 8. After spin drying, they are dried at a low temperature of 40℃ to 60℃ for 5 to 7 hours.

[0018] Preferably, the treatment solution used for the surface treatment in step b) is prepared from raw materials comprising the following components:

[0019] 100 parts by weight of glacial acetic acid;

[0020] 2-6 parts by weight of zinc chloride;

[0021] Surfactant: 0.1–0.5 parts by weight;

[0022] Acetic anhydride 1.5 to 6.5 parts by weight.

[0023] Preferably, the surface treatment process specifically includes:

[0024] Heat the water bath to 60℃~75℃, then immerse the button in the treatment solution. The mass ratio of the button to the treatment solution is 1:(1~5), and the treatment time is 1h~4h.

[0025] Preferably, the pH adjustment process in step c) specifically involves:

[0026] Soak the treated buttons in water for 20 to 40 minutes, then change the water and soak and wash them again until the pH value is greater than 6.

[0027] Preferably, the staining temperature in step c) is 70℃~80℃ and the time is 15min~25min;

[0028] The drying temperature is 40℃~50℃, and the time is 0.5h~1.5h.

[0029] The present invention also provides a ring-patterned button, which is prepared by the preparation method described in the above technical solution.
