Lattice Nine Sweden: Unitard Built on Nylon/Spandex Spacer Knit
Lattice Nine, based in Sweden, needed a unitard that delivered recycled content traceability without moving away from a clean, commercial silhouette. The finished fabric was Nylon/Spandex Spacer Knit.
Project brief and fabric selection
The fabric selected combines Spacer Knit (two faces joined by spacer yarns) with polyamide 6 with 18-22% elastane, giving high recovery and a silky hand. Construction is two faces joined by spacer yarns at 280-380 GSM. The brief also asked for plus a resilient middle layer. Each lot was checked against GRS transaction certificate before cutting began.
Construction and fit decisions
Pattern and construction were adjusted around the chosen fabric: seam placement moved away from high-friction areas, stitch density was matched to the elastane content, and the fit block was revised once the first wear trial showed the panel tension distribution. The development brief set the outcome as every lot shipped with GRS transaction certificates.
Dyeing and finishing approach
Finishing was limited to processes that support recycled content traceability. Soft handle came from construction rather than heavy softening, which keeps performance stable through repeated washing. Consistency between repeat lots mattered more to Lattice Nine than an isolated best result.
Measured results
Measured outcome: every lot shipped with GRS transaction certificates, verified by GRS transaction certificate. Size sets were checked after five home washes to confirm that dimensional change stayed inside the agreed tolerance before bulk release. Fabric Nylon/Spandex Spacer Knit supplied the base behaviour for recycled content traceability.
Repeat order performance
The style moved to repeat orders after two seasons. Bulk fabric is now booked against a fixed recipe, with test reports issued per lot, and the Spacer Knit construction is used for additional colourways in the same programme. The Sweden market requires documentation, so reports shipped with every lot.
