OCR 10KL (25/02/2568) 1. The dyeing process using fresh fruit of the Carissa carandas plant (Carissa arjuna) and over-dyeing with a post-mordant for textile and paper applications consists of the following steps: a. Preparation of the mordant. b. Preparation of textile dye from Carissa carandas fruit: Select 10-20 kilograms of fresh, purple Carissa carandas fruit, wash it twice with clean water, remove the stems and leaves, and then extract only the juice. Filter the juice through a 180-200 mesh screen 1-2 times. c. Dyeing process using the fresh Carissa carandas fruit and over-dyeing with a post-mordant: Soak the textile material in the Carissa carandas fruit juice at a ratio of 1 part textile material to 50 parts fruit juice. Then heat the material using a gas or electric stove. When the temperature reaches 90 degrees Celsius, stir continuously for 30-60 minutes. Remove the textile material from the pot, rinse by soaking in distilled water for 10 minutes, then over-dye with a mordant. Soak the textile material in the mordant at a ratio of 1 part textile material to 10-50 parts mordant. Then, boil over a gas or electric stove at 90 degrees Celsius, stirring continuously for 30-60 minutes. Remove the textile material from the dyeing pot and air-dry at room temperature. 2. The dyeing process using fresh fruit extracts of the Carissa carandas plant and over-dyeing with mordants for use in textiles and paper, as per claim 1, includes a washing step after dyeing. The washing process involves heating the dyed textile material at a ratio of 10-20 grams to 1 gram of liquid synthetic soap per 1,000 milliliters of water using a gas or electric stove to 90 degrees Celsius, stirring continuously for 10-15 minutes. After this time, the material is immersed in distilled water for 10 minutes, repeated three times. Finally, it is air-dried at room temperature. 3. A dyeing process using fresh fruit extracts of the Carissa carandas plant and over-dyeing with mordants for use in textiles and paper under claim 1 or 2, where the textile material can be selected from silk, wool, cotton, or paper. 4. The dyeing process using fresh fruit extracts of the Carissa carandas plant and over-dyeing with mordants for use in textiles and paper, as per any one of claims 1 through 3, where the mordant can be selected from ash water, lime water, iron rust water, salt water, copper sulfate water, alum water, or tamarind water, either individually or in combination. 5. The dyeing process using fresh mangosteen fruit and over-dyeing with mordants for use in textiles and paper, as per claim 4, where the mordants are prepared as follows: - Ash water, by dissolving ash in distilled water to a concentration of 5-10% by volume. - Lime water, by dissolving red lime in distilled water to a concentration of 5-10% by volume. - Iron rust water, by soaking 3-5 kg of iron material in 2,000 ml of distilled water for 7 days, then stirring to ensure the iron rust water is well mixed. Then filter the iron rust water through a mesh screen with 180-200 holes per inch 1-2 times. - Salt water: Dissolve table salt in distilled water to a concentration of 5-10% by volume. - Copper sulfate water: Dissolve copper (II) sulfate in distilled water to a concentration of 5-10% by volume. - Alum water: Dissolve alum in distilled water to a concentration of 5-10% by volume. - Tamarind water: Dissolve 3-5 kilograms of tamarind in 2,000 milliliters of distilled water, then filter the tamarind water through a mesh screen with 180-200 holes per inch 1-2 times. 6. A dyeing process using the fruit extract of the Carissa carandas plant and over-dyeing with mordants for use in textiles and paper under any one of claims 3 through 5, where the textile material is paper. 7. The dyeing process using fresh fruit extracts of the Carissa carandas plant and over-dyeing with mordants for use in textiles and paper, as per claim 6, which includes additional steps in the dyeing process such as filtering the paper with a screen of 180-200 holes per inch 1-2 times, followed by rinsing with distilled water for 10 minutes.
