Weft knitted fabric can undergo various finishing treatments to enhance their performance, appearance, and overall quality. Here are some common finishing processes:

Sanforizing (Pre-Shrinking): This process pre-shrinks the fabric to minimize further shrinkage after washing. It helps maintain the size and shape of the garment.

Mercerizing: This treatment involves soaking the fabric in a sodium hydroxide solution, which increases its luster, strength, and dye affinity, giving it a more luxurious feel and brighter colors.

Softening: Softening agents are applied to improve the hand feel of the fabric, making it softer and more comfortable to wear.

Water Repellent Treatment: This treatment applies a coating that makes the fabric resistant to water, which can be useful for outdoor or performance garments.

Flame Retardant Finishing: Chemicals are applied to the fabric to make it resistant to fire, enhancing safety for certain applications.

Anti-Pilling Treatment: This process reduces the tendency of the fabric to form pills or fuzz balls, keeping it looking new for longer.

Anti-Wrinkle Finishing: This treatment helps the fabric resist wrinkling, reducing the need for ironing and maintaining a smooth appearance.

Antimicrobial Treatment: Chemicals are applied to inhibit the growth of bacteria and fungi, which can help keep the fabric fresher and odor-free.

Dyeing and Printing: Weft knitted fabrics can be dyed or printed with various patterns and colors to enhance their appearance. Techniques include screen printing, sublimation, and digital printing.

UV Protection: This treatment adds a layer of protection against harmful UV rays, making the fabric suitable for sun-exposed applications.

Each finishing treatment can be tailored to meet specific requirements based on the intended use of the fabric, whether for everyday wear, sportswear, or specialized applications.
