To prevent shrinkage, it is crucial to give proper attention to pre-treatment and surface treatment. This reduces moisture changes within the fibres that can cause shrinkage. Following chemical guidelines and specifications during fibre treatment is also essential. In order to reduce or eliminate shrinkage, precise control over time and temperature is necessary. Additional trials may need to be performed to determine the optimal concentration percentage of 4% within a specific time frame. Prolonged exposure to chemicals and sudden temperature changes or overheating can result in shrinkage.
