The difference between warp and weft of polyester yarn, all kinds of woven fabrics are made of warp and weft, which are interwoven according to certain rules.
Warp yarns - yarns arranged longitudinally (parallel to the selvedge).
Weft yarns - yarns arranged laterally (perpendicular to the selvedge).
Woven cotton yarns require high strength, especially for warp yarns.
If the strength of the warp yarn is not high, it is easy to cause the yarn to be interrupted during the weaving process, thereby affecting the efficiency.
For weft yarns, the strength requirements are not as high as warp yarns.
Weft yarns are simply yarns inserted between the warp yarns to form the fabric.
The difference between warp and weft
All kinds of fabrics have length and width. The length parallel to the edge of the fabric is called the length of the fabric, and the direction of the length of the fabric is the warp direction of the fabric; the length perpendicular to the edge of the fabric is called the width, and the direction of the width is the weft of the fabric. Towards. The yarns in the warp direction are called warp yarns, and the yarns in the weft direction are called weft yarns.
Usually we see a fabric label similar to 60S to 40S, which means that the warp yarn becomes the weft yarn, which means that the warp direction of the fabric is 60 yarns, and the weft direction is 40 yarns.
