FAQ: Trims & Constructions in Knitwear
Linking is a specialized joining method where each stitch from two panels is joined by machine needle, creating a clean, flat, and durable seam. Unlike overlock, it does not bulk the edge, ensuring luxury appearance and comfort. Because it requires skilled technicians and is slower, it’s considered a premium construction standard in high-end knitwear.
Seamless (WholeGarment) knitting produces the entire garment in one piece, with no seams, offering superior comfort and reducing waste—ideal for luxury and sustainable brands.
Fully Fashioned knits panels to shape, then joins them with linking, allowing precise fit and tailored design—suitable for premium sweaters and cardigans.
👉 Rule of thumb: choose seamless for eco & comfort positioning, fully fashioned for precise, tailored fit.
Yes, many trims such as zippers, buttons, tapes, and labels are available with OEKO-TEX® Standard 100 certification, ensuring they are free from harmful substances. For luxury and EU/US retailers, nickel-free zippers and sustainable trims (e.g., corozo buttons, recycled polyester zippers) are often required.
Natural and artisanal trims elevate brand value:
Corozo or horn buttons → eco-luxury image
Metal zippers with custom pulls → premium branding
Woven labels & tapes → refined detail
Luxury buyers look for trims that combine sustainability, durability, and exclusivity.
Seam distortion can occur due to inconsistent tension, yarn stretch, or finishing shrinkage. To prevent this:
Use linking or fully fashioned for premium quality
Set tight QC for overlock/coverstitch (stitch per inch control)
Pre-test shrinkage & tension during sampling
Align trims (e.g., zippers) with garment stretch properties
This ensures stable, consistent fit even in large-scale production.
