1. The defoamer used for dyeing and the softener in the anti-crease bath must be paid attention to separately. If the emulsifier can emulsify, it may not be able to withstand temperature. If you choose a poor emulsifier, the silicone oil will separate and stick to the cylinder wall. It will absorb dyes. It is difficult to remove ordinary chemicals. After a long time, the silicone oil containing dyes will be cracked due to long-term high temperature. And peeling, this small piece of peeling will stain the cloth, thus forming a "color point".

2. There are acids, bases, anions and cations in the dye solution that will destroy the emulsifier or combine with the emulsifier, causing the emulsifier to lose its emulsifying function and separate the silicone oil.

3. This phenomenon is not only caused by high-temperature dyeing, but the heat exchanger of the room temperature dyeing machine is also very high temperature, and the above-mentioned phenomenon will also be caused when the dye liquor passes through.
