Question

Aldehyde pre-treatment is generally carried out for:

• A. Garment leather
• B. Chamois leather
• C. Sole leather
• D. Lining leather

Hint:

Chamois leather's soft, water-absorbing properties are a result of aldehyde tanning, which makes it different from other types of leather.

Answer 1

The Correct Option is B

Aldehyde pre-treatment is primarily used for chamois leather, which is processed using aldehyde chemicals. This process imparts a unique soft texture to the leather, making it highly absorbent and flexible. Chamois leather is typically used for cleaning cloths and soft leather goods, and aldehyde pre-treatment is critical for achieving its characteristic properties. Step 1: Role of Aldehyde Pre-treatment
- Aldehydes help in softening and conditioning the leather, making it more flexible and water-absorbent, which is particularly desirable in chamois leather.

Step 2: Conclusion
Thus, aldehyde pre-treatment is most suitable for chamois leather (Option b).
