Rib fabric is a type of knit fabric that has raised vertical lines or “ribs” on both sides. It is created by using two sets of needles on a knitting machine, which knit a series of vertical stitches that form the ribs.

Rib fabric is typically made from a blend of cotton and synthetic fibers, such as polyester or rayon. It is known for its stretchiness, durability, and texture. The ribbing creates a natural stretch in the fabric, which makes it ideal for use in garments that need to be form-fitting or have a snug fit.

Rib fabric is commonly used in clothing, such as t-shirts, tank tops, sweatshirts, and other casual wear. It can also be used in activewear, such as leggings, sports bras, and yoga pants.

Rib fabric is available in different weights and textures, from lightweight and fine to heavy and bulky. It can also be treated with different finishes, such as dyeing or printing, to create different colors and patterns.

Rib fabric is easy to care for and can be machine-washed and dried. It is a versatile fabric that can be used in many different applications, from clothing to home decor.
