Sourcing Socks for Europe?
Advanced 156N Fine-Gauge Knitting and In-House Design, Without the Tightening Cost Curve
At Biorun Socks, we combine fine-gauge production with design-led development to deliver European-quality socks at a cost structure that protects your margin. We run a large installed base of 156N intelligent integrated knitting machines, support every program with an in-house design planning and R&D team, and meet the certifications European retail requires — from first concept and sampling through to finished, fully inspected goods.

01 What the 156N gauge actually means for your socks
At 156 needles per cylinder, the fabric sits in the fine-gauge range — the zone European customers tend to expect:
▪ Crisp, detailed jacquard patterns. Small logos, repeated motifs, and multi-color graphics render cleanly instead of bleeding or looking coarse.
▪ A smoother, denser hand-feel. The knit surface reads as premium in the hand — the difference customers notice before they check the price tag.
▪ Better shape retention. A tighter knit holds its form through repeated washing, so the sock still fits the way it did on day one.

02 Machines are only half the story: in-house design and R&D
A good machine still needs a good idea. Biorun pairs its equipment with an internal planning and R&D function across Shanghai, GuangZhou, Yangzhou, and Ankang:
▪ Design planning, not just production. Our team works from your trend direction, target customer, and price band to develop color stories, structure, and seasonal concepts — not only knit the sample you send.
▪ Full in-house development. Designers, pattern technicians, sampling, and lab testing operate under one roof, so feedback turns into a revised sample quickly.
▪ Own embroidery and decoration. Brand monograms, logos, and custom embellishment are handled in our own embroidery workshop.
▪ Tested before it ships. In-house lab testing checks construction, durability, and fit before bulk production begins.
Whether you need an ODM collection built around our own designs or a fully custom OEM program from your artwork, the planning-to-production chain stays inside our factory network.


03 Automation and quality control that protect your margin
Cost advantage should never mean compromise. Two systems keep quality steady at scale:
▪ Biorun Digital Management System. Production progress is monitored end to end, scheduling uses real-time data, and decisions on delivery, quality, and cost are data-driven rather than estimated.
▪ Digital-twin workshop in Ankang. We monitor, simulate, and optimize the knitting line in real time — reducing idle time and keeping each stage running at peak performance.


Every order moves through a rigorous full-inspection stage and smart packing with human oversight, built for secure global logistics.
Certifications we hold
Certifications European buyers consistently ask for: BSCI · OEKO-TEX · GRS · OCS · RCS · GOTS · QMS · Higg FEM · FSC · SCAN Security · SLCP Gateway · Kohl's audit standards |
04 Why brands are pairing Europe-ready design with our cost structure
We're not competing on being the cheapest. We're competing on keeping European-level quality while the cost curve in traditional sourcing regions keeps rising:
▪ Automation absorbs labour pressure. Intelligent knitting and automated flow reduce reliance on manual steps, so wage inflation abroad doesn't translate directly into your unit price.
▪ Scale spreads fixed cost. Two production bases (Yangzhou, Jiangsu and Ankang, Shaanxi) and a large machine fleet let volume run efficiently without sacrificing consistency.
▪ Stable delivery, planned ahead. Digital scheduling and real-time visibility make lead times predictable, which matters when you plan a European selling season.
The result is a practical diversification move: you keep a trusted European-quality standard, remove single-region cost exposure, and hold a healthier margin. |

Frequently Asked Questions
Q1 What sock types can you produce on the 156N fine-gauge machines?
The 156N gauge suits fine dress and casual socks, detailed multi-color jacquard, branded graphic socks, and thin sport or everyday styles. We can discuss your specific design and confirm the best gauge for it during sampling.
Q2 Do you offer both OEM and ODM, or do you only knit designs we provide?
Both. We run fully custom OEM programs from your artwork and ODM collections developed by our own design and planning team, including color stories and seasonal concepts.
Q3 Which certifications do European retailers typically ask for, and do you hold them?
We hold BSCI, OEKO-TEX, GRS, OCS, RCS, GOTS, QMS, Higg FEM, FSC, SCAN Security, SLCP Gateway, and Kohl's audit standards. Certification documents can be shared during supplier review.
Q4 How does Biorun compare with sourcing from Turkey or other nearshoring regions on cost?
Rather than quoting a blanket comparison, we build a cost plan against your actual product, quantity, and requirements. Our automation and scale let us hold fine-gauge quality at a competitive unit cost even as nearshoring labour and energy prices rise; we're happy to compare line-by-line on your next sample.
Q5 Can you develop designs to a European trend direction rather than copying existing styles?
Yes. Our in-house planning team works from your trend mood board, target customer, and price band to develop original concepts, colors, and patterns before sampling.
Q6 Where are your factories, and how do you control quality at scale?
We operate two intelligent bases in Yangzhou (Jiangsu) and Ankang (Shaanxi), supported by our digital management system, a digital-twin knitting workshop, in-house lab testing, and a full-inspection packing stage.
Q7 What information do you need to start?
Send us your target market, reference styles or mood board, target price band, estimated quantity, and delivery window. We respond with a development proposal, sample plan, and cost estimate.
