I believe you are referring to “jersey fabric.” Jersey is a type of knit fabric that is commonly used in clothing, especially for t-shirts and other casual wear. It is made from a blend of cotton, wool, or synthetic fibers such as polyester or rayon.

Jersey fabric is known for its softness and stretchiness, which make it comfortable to wear and easy to move in. It is typically lightweight and breathable, making it ideal for use in warmer weather.

Jersey fabric can be made in a variety of weights and textures, from fine and smooth to heavy and textured. It can also be treated with different finishes, such as dyeing or printing, to create different colors and patterns.

Jersey fabric is easy to care for and can be machine-washed and dried. It is also versatile and can be used in a variety of different styles and designs, from sporty to dressy.

In addition to clothing, jersey fabric can be used in other textile applications, such as bedding, curtains, and upholstery. It is a popular choice for many different products due to its softness, stretchiness, and versatility.
