QTN Pro Tips – For Sewers

Metal zippers can sometimes discolor or stain surrounding fabrics during garment production. This issue is not only frustrating but can also lead to costly rework.

YKK’s article, “How to Prevent Metal Zippers from Changing Color and Staining a Garment,” provides guidance on avoiding these problems. The key is to understand the dyeing process, as chemical reactions may occur when metal components—such as elements, sliders, and stops—come into contact with certain chemicals.

Recommended best practices include:

• Installing zippers after the dyeing process
• Thoroughly washing garments post‑dye to remove chemical residues
• Conducting small‑batch, pre‑production tests to identify potential issues in advance
