Looped fabric, also known as fish scale fabric, double jersey, and unit fabric, is a knitted fabric that features single-sided or double-sided loops. During the weaving process, certain yarns are woven at a specific ratio, forming loops on the rest of the fabric's yarns and remaining on the surface, thereby creating the looped fabric.

Looped fabric feels soft and has a thick texture. It boasts excellent absorbency and thermal properties. Looped fabric offers great wearing performance. The downside of looped fabric is that its thermal properties are best suited for autumn and winter seasons. It can easily pull apart if not handled with care while wearing.

Knitted fabrics are formed by bending yarns into loops and intertwining them. The difference between knitted and woven fabrics lies in the yarn's shape within the fabric.

Loop pile fabric is a type of knitted fabric. During weaving, certain threads are looped at a certain proportion over the remaining threads of the fabric, remaining on the surface, forming the loop pile. It can be categorized into single-sided and double-sided loop pile. Loop pile fabric is typically thicker, with the looped section capable of trapping more air, thus offering warmth. It is commonly used in autumn and winter apparel accessories.
