Give four objective of preparing fabric before dyeing process takes place?

1. To remove any impurities or contaminants from the fabric, such as dirt, oil, or sizing, which could interfere with the dyeing process and result in uneven or poor color penetration.

2. To improve the absorbency of the fabric so that it can better take up and retain the dye, resulting in more vibrant and long-lasting colors.

3. To ensure that the fabric is properly pre-treated and prepared for the specific type of dye being used, whether it is a natural, synthetic, or reactive dye, in order to achieve the desired color and colorfastness.

4. To prevent any potential issues with shrinkage, distortion, or damage to the fabric during the dyeing process by pre-treating and stabilizing the fabric beforehand.

1. Remove impurities: Prepare fabrics to remove natural oils, waxes, and other impurities that can prevent dye from penetrating the fibres evenly.
2. Improve dye absorption: Pre-treat fabrics by opening up the fibres and allowing the dye to penetrate more easily, resulting in better colourfastness and vibrancy.
3. Maintain fabric strength: Strengthen fabrics by stabilizing the fibres, preventing damage during the dyeing process and ensuring the fabric retains its original strength.
4. Ensure even dyeing: Create uniform fabric conditions by removing any variations in absorbency, ensuring that the dye is evenly distributed and produces a consistent colour result.
