Discussion
Consider the following statements about cationic softeners.
1. They give excellent softness and are highly substantive.
2. They tend to yellow the fabric on heat or ageing.
3. They are fully compatible with anionic dyes and brighteners.
Answer: D
The first two are correct. The third is exactly the difficulty, since the opposite charges cause precipitation or quenching, which is why compatibility must be checked before use. Yellowing shows up after heat or long storage.
