👉 The jersey fluid is a concept in textile engineering that describes the way a fabric, particularly a jersey knit, moves and flows with the body. Unlike more structured fabrics such as denim or wool, jersey knit has a unique, stretchy structure that allows it to drape and move more freely around the body. This fluidity is due to the interlocking loops of yarn that create a stretchy, open weave, enabling the fabric to conform closely to the body's contours while still maintaining a smooth, comfortable feel. This characteristic makes jersey knit ideal for garments that require flexibility and comfort, such as t-shirts, sportswear, and casual clothing.
