Why Jiayi

One chain, not a patchwork of suppliers

In seamless garments, quality is rarely decided by a single process. It is decided in the handovers between them. We keep knitting, dyeing, stitching and inspection under one standard and one production sheet.

01

Vertical integration

Own knitting floor, coordinated dyeing, stitching lines and packing — closed loop from raw yarn to finished carton, with fewer handover risks on quality and lead time.

02

Equipment & R&D

70+ SANTONI computerised jacquard machines and 200 sets of Japanese sewing equipment, supported by 20+ technicians for jacquard design, structure development and functional fabrics.

03

Global delivery

Self-operated import and export licence. Products ship to Germany, France, Spain, the US, Japan and Korea, serving retail and brand clients including REWE and ROSSMANN.

Product Range

Four product lines, one manufacturing standard

Seamless construction means fewer seams, a more stable fit — and far more freedom in pattern design.

Seamless underwear
01 Seamless

Seamless underwear

Tube-knit construction replaces side seams entirely. The fabric follows the body, reducing friction and pressure marks — stable through repeated wear and washing.

Shapewear
02 Shapewear

Shapewear

Sculpting is a question of tension zoning — where it holds, where it releases, and by how much. We control local pressure through knit structure and density, balancing effect and comfort.
