Question

Which property is mainly incorporated by melamine syntan?

• A. Grain Tightness
• B. Selective Filling
• C. Bleaching
• D. Neutralization

Hint:

Melamine syntan improves grain tightness, resulting in smoother and more resilient leather surfaces, which is ideal for high-quality leather goods.

Answer 1

The Correct Option is A

Step 1: Melamine Syntan's Role in Leather
- Melamine syntan is used in leather processing to improve the surface characteristics of the leather, especially its texture and appearance. One of the primary effects of melamine syntan is enhancing grain tightness, which refers to the smoothness and compactness of the leather's surface.

Step 2: Explanation of Other Options
- Selective filling, bleaching, and neutralization are processes used in leather treatment, but melamine syntan is particularly known for enhancing grain tightness. It does not primarily affect the other properties listed.

Step 3: Conclusion
Thus, the main property incorporated by melamine syntan is (a) Grain Tightness.
