The weight of the fabric, ie the weight of the fabric, is the thickness or density of the fabric in daily life. The garment products, which are produced from a fabric with a high weight of square meter, are mostly produced for the garments used in winter seasons. On the other hand, apparel products which are produced from a fabric with a low weight of square meters are produced mainly for the garments used in summer seasons.

The knitting, width, length, thickness or density of the fibers or yarns forming the fabric, and the density or density and thickness of the fabrics are the main structural properties of the fabrics. The bulking properties of the fabrics that consumers are emphasizing today are directly related to the density, weight and softness of the fabric. The low density of the fabric changes the fabric's attitude and increases the air permeability.

Density is the number of threads entering a certain length in the width and length direction of the fabric. This feature is very effective on the softness and density of the fabric. The fabric's specific structure, flexibility and air permeability are also effective on the density of the fabric.

In addition, the amount of twist is effective on the density of the fabrics. As the amount of twist increases, the density of the fabric increases. The density of the fabrics used in the thick yarns in the texture is high. The density of the high weft and warp yarns in the fabric texture, ie the knitting of the fabric, is also high. Finally, the finishes applied to the fabric also affect the density of the fabric.

The physical tests performed in the authorized laboratories are based on various standards issued by local and foreign organizations. The tests to determine the density of fabrics are based on the following standard: TS EN ISO 1140 Ropes - Polyamide - 3-, 4-, 8- and 12- sleeves.

All laboratories must have a strong technological infrastructure and an experienced and trained staff in order to provide quality, fast and reliable results.
