Method of recognizing latitude and longitude of textile fabrics

The latitude and longitude of textile fabrics have certain differences in appearance, such as patterns, bars, and so on, and also have different performances, such as extensibility and drape.

One is based on the fabric edge identification

There is a cloth-edge fabric, parallel to the fabric edge, that is, the longitudinal direction of the warp. The direction perpendicular to the cloth edge, that is, the width direction is the weft.

Second, according to the density of textile fabrics

The density of the general fabric is greater than the weft density.

Three according to the raw material identification of yarn

The warp yarns of intertwined fabrics generally have better raw materials and higher strength.

In the interwoven fabrics of different raw materials, generally cotton wool or cotton intertwined fabrics, cotton as warp yarn. Wool interwoven fabrics, silk warp yarn. Wool, wool interwoven fabrics, the silk, cotton warp. Natural silk and twisted silk fabrics, natural silk yarn. In natural silk and viscose filament interwoven fabrics, the natural yarn is warp yarn. Due to the wide variety of uses of fabrics and the variety of fabrics, the requirements for fabric raw materials and organizational structures are also varied. Therefore, when judging, the specific conditions of the fabrics must be determined.

Four According to the direction of yarn formation

When the yarn formation direction of the single yarn fabric is not the same, the Z direction is the warp direction, and the S direction is the weft direction.

Five according to the degree of yarn recognition

Generally speaking, the longitude is the longitudinal direction, and the small degree is the latitude direction.

Sixth According to the structure of the yarn

If one direction of the fabric is a strand and the other direction is a single yarn, the strand is a warp.

If the warp and weft yarns of the fabric are of different thicknesses, the warp and weft yarns are generally yarns, and the weft yarns are mostly flower yarns (such as slub yarns).

Seven identification based on sizing

The sizing direction of the general fabric is longitudinal, and the direction of non-sizing is latitude.

Eight according to scar identification

The scars are pronounced with scars oriented in the direction of the warp.

Nine according to the fabric's warp and weft yarn density, direction and twist recognition

When the density of the warp and weft yarns of the fabric, the twisting direction, and the twisting degree are not significantly different, the warp yarns are uniform in the yarn and the luster is better.

The fabric has a system of yarns with a variety of different linear densities, and the direction of the system yarn is warp.

Ten according to the fabric's scalability

The stretchability of the fabric is generally smaller in the warp direction and larger in the weft direction.
