The Knowledge Hub exists to make decisions easier on knit fabric selection, dyeing, printing and finishing, quality testing, sustainability regulation and sourcing. This page explains who produces the content and by which rules.
Who writes the guides?
The guides carry the byline of Cemal Karabiçek, founder and general manager of KARCEM Tekstil. The content is based on experience in greige knitting and in coordinating commission dyeing, printing and finishing. Each guide shows its author and last-updated date at the top.
Technical review
The guides are not currently reviewed by an independent technical reviewer. When a guide is reviewed by a quality or laboratory specialist, the reviewer’s name, job title and review date will be shown at the top of the guide. Without a real review, this line is not shown.
Sourcing policy
For standards, test methods and regulation we rely on the primary source: standards bodies such as ISO, AATCC and ASTM, European Union legal texts, and the own publications of programmes such as GOTS, Textile Exchange, ZDHC and OEKO-TEX. Only pages whose link has been opened and whose content has been verified enter the “References” list at the end of each guide. A standard number or date we cannot verify is removed from the text.
Figures about KARCEM (for example monthly knitting capacity or the colour tolerance target) are the company’s own declarations and appear in the same form on the corporate pages. We do not present a certificate we do not hold as our own.
Translations and use of AI
The source language of the guides is Turkish. The English, German, Dutch, Russian, Italian and Arabic versions were translated with AI, and these translations have not yet been proofread by a human. English technical terms are checked automatically against a single termbase. If a translation contradicts the Turkish text, the Turkish text prevails — please let us know.
Updates
The “Last updated” date on each guide moves forward only when the content actually changes; design fixes do not change the date. We aim to review the regulation guides monthly and all other guides at least once a year. Substantive changes to the regulation guides are listed in the page’s “Version history” section.
Corrections
If you spot an error, outdated information or a missing source, write to us through our contact page. We apply verified corrections to the guide and update its date.
