The classification of woven fabrics is made according to different principles. Thus, according to their structure, fabrics are of three classes: single-ply (simple structured) fabrics, complex-structured fabrics and artificial and synthetic fabrics. Fabrics are classified in two classes: garments and industrial fabrics. According to the raw materials used in weaving, fabrics can be classified into four classes: fabrics made of animal fibers, fabrics obtained indoors, fabrics made of vegetable fibers and fabrics made of fibers. Finally, according to the bonding technique of weft and warps, the tissues were grouped into three groups: simple tissues, reinforced tissues and special tissues.

However, there is also a variety of self-specific tissues without any classification. For example, reinforced fabrics, woolen fabrics, double-layered fabrics, multi-layered fabrics, silk fabrics, cotton fabrics, linen fabrics, polyester, polyamide and acrylic.

However, all woven fabrics, no matter which group they belong to and which methods are produced, must have certain criteria and standards. These physical properties such as strength, elasticity (extensibility), softness, weave, pattern, color and brightness such as appearance, keeping warm, moisture absorption, casting, permeability and shrinkage are determined by the analyzes to be performed.

In addition to all these features, tissue type analyzes of fabrics are carried out by national or international accreditation bodies, which are accredited in accordance with the standards of TS EN ISO / IEC 17025 General Conditions for the Competence of Testing and Calibration Laboratories.

These laboratories comply with the standards published by local and foreign organizations during these tests. In this context, Ekoteks 1 standard is used for tissue type analysis.

In addition, laboratories need to have state-of-the-art equipment and equipment and an experienced and trained staff to ensure reliable, fast and quality results.
