(1) If the fabric being identified has a selvedge, it shall be parallel to the selvage The direction of the yarn is the warp direction, and the other side is the weft direction.

(2) The direction of sizing is the warp yarn, and the direction of the weft yarn is not sizing.

(3) Generally fabric has a higher density in the warp direction and a lower density in the weft direction.

(4) For fabrics with obvious reed marks, the direction of the reed marks is the warp direction.

(5) For half-thread fabric, usually the strand direction is the warp direction and the single yarn direction is the weft direction.

(6) If the yarns of the single yarn fabric are twisted at different times, the Z twist direction is the warp direction and the S twist direction is the weft direction.

(7) If the warp and weft yarn characteristics, twist direction, and twist degree of the fabric are not significantly different, the yarn will be uniform and glossy. For the meridian direction.

(8) If the twists of the fabric yarns are different, the ones with higher twist are mostly in the warp direction, and those with smaller twist are Latitude.

(9) Towel fabrics have terry yarns in the warp direction, and terry-free yarns in the weft direction.

(10) Strip fabric, the strip direction is usually in the warp direction.

(11) If the fabric has a system of yarns with multiple different characteristics, this direction is the warp direction.

(12) For leno fabrics, the direction of the twisted yarn is the warp direction, and the direction of the untwisted yarn is the weft direction.

(13) In interwoven fabrics of different raw materials, generally cotton wool or cotton and linen interwoven fabrics, cotton is the warp; in wool and silk interwoven fabrics, silk is Warp yarns; in wool, silk and cotton interwoven fabrics, silk and cotton are warp yarns; in natural silk and spun silk interwoven fabrics, natural threads are warp yarns; in natural silk and artificial silk interwoven fabrics, natural silk is warp yarns.
