Coating is a process where a protective or functional layer is applied to the yarn’s surface. This layer improves resistance to abrasion, moisture, and chemical exposure, while also enhancing elasticity and texture. Specialized machines apply coatings evenly, which is essential for technical yarns used in demanding environments.

Drying follows coating or washing and is essential to eliminate moisture from the yarn. Excess moisture can weaken yarn strength and reduce processing efficiency. Controlled heat are used to dry the yarn uniformly, without causing deformation or damage.

Priming involves applying chemicals or additives to the yarn to improve adhesion between fibers or with other materials. This is especially important before processes like weaving or knitting. Primed yarns offer better bonding, resulting in improved durability and fabric performance.

Shrinking is a controlled process where the yarn is intentionally reduced in length or size. It helps stabilize fabrics, preventing changes during end use. This process improves dimensional stability and texture, especially in natural fibers prone to shrinking.
