Materials · our fibre strategy

One seamless core. Four fibre programmes.

Standard nylon is where most seamless programs start. From there, brands climb the ladder: GOTS organic cotton, bamboo and modal for natural hand-feel; RWS wool for thermoregulation; GRS recycled nylon and polyester for circular claims; bio-based nylon and spandex for the headline your marketing team wants. All knitted on the same 30 Santoni machines.

Our story

Fifteen years, one machine hall.

We don't tell client stories — nearly all of our work sits under NDA, and we intend to keep it that way. Instead, here is ours: how a six-machine workshop grew into a seamless-first factory with three audited partners.

2011 · The workshop
Chapter 01

Six machines, one craft.

Founded with six second-hand circular machines, knitting nylon seamless for domestic brands. One focus from day one: the tube.

2011Founded
2016 · First Santoni hall
Chapter 02

Santoni machines, direct export.

Bought our first Santoni SM8-TOP2 machines and moved into our own plant. Started shipping direct to European brands — tech packs in, cartons out.

Quietly run, precisely measured.

Conservative numbers, conservative claims. The kind of metrics a sourcing manager can paste into a board deck without re-checking.
