• Anti-microbial Finishing: This process involves applying anti-microbial agents to the fabric to prevent the growth of bacteria, fungi, and other microorganisms.
• Flame Retardant Finishing: This process involves applying flame retardant chemicals to the fabric to make it less flammable.
• Water-Repellent Finishing: This process involves applying chemicals to the fabric to make it water-resistant.
• Dyeing and Printing: These processes involve adding colors and designs to the fabric by using dyes and pigments.

3. Combined Finishing: Combined finishing is a combination of both mechanical and chemical processes. Some common combined finishing processes include:

• Mercerization: This process involves treating the fabric with a caustic soda solution and then rinsing it with water. This process improves the fabric's strength, luster, and affinity for dyes.
• Sanforization: Sanforization is a process that involves treating the fabric with steam and pressure to reduce shrinkage.
• Enzyme Finishing: This process involves using enzymes to break down the fabric's fibers, resulting in a softer and smoother texture.

In summary, textile finishing processes are diverse and can be classified into three broad categories: mechanical finishing, chemical finishing, and combined finishing. These processes alter the fabric's physical and chemical properties to achieve specific desired characteristics such as softness, water repellency, and colorfastness.
