TS 7566

TS 7566 is a terminology and classification standard for seam types, covering how different seam types are classified, designated, and illustrated, with particular emphasis on the seam types most commonly used in the clothing industry. In general textile practice, a seam is a fundamental joining element used to connect fabric parts; this standard provides a shared language and a consistent way to represent those seam constructions.

Naming seam constructions in a common system

In textiles and apparel, the same seam construction may be described differently across factories, technical files, or product specifications. The value of a standard like this lies in aligning seam types through common terminology and codes, reducing ambiguity in communication. That makes it useful for pattern development, technical specification writing, quality documentation, and production instructions that need a consistent classification basis.

Why illustrated descriptions matter

The emphasis on illustrations shows that seam types are identified not only by name but also by their structure and visual arrangement. In broader technical context, this matters because seam formation, stitch sequence, thread arrangement, and the relative position of fabric edges can influence durability, flexibility, and appearance. This standard supports the recognition and consistent description of such seams; those performance-related points are general textile knowledge rather than claims about specific requirements in the text.

This Turkish edition was prepared from ISO 4916:1982 and has since been withdrawn. Its subject is seam-type terminology, so it functions as a controlled reference framework for understanding and comparing different seam constructions.
