Spin-and-Yarn
Spinning, count, twist & yarn quality
Controls draft, twist and speed across ring, rotor and air-jet frames to hold count (Ne), CV%, twist and tenacity inside buyer spec, and predicts end-breaks before they cascade.

How we work
01
Everyone spends time on a floor. Opinions formed from a dataset alone do not survive contact with lint.
02
New capability ships in observe mode first, always. No exceptions for a good demo.
03
If it is not in production, we say so, internally, to customers and on this website.
04
The person at the machine is the domain expert. The agent is the junior colleague.
05
Not against a benchmark we chose. Against what the mill produced last year.
06
Runbooks, reasoning traces, decisions. Undocumented autonomy is not autonomy.
Trust signals
No customer results are published yet. These are platform facts and plan terms from our own documents. Outcomes will be measured against each mill’s own trailing twelve months, in shadow mode before anything is controlled.
Mill agents, one per stage, from spinning to release.
Products in the loop: Vireon, Spindra, Loomix, Shadeon, Doffex and Twinly.
Design partners we are onboarding first, one wedge workflow each.
Per line per month on the Line plan. Mill and Enterprise sit above it.
Items marked ASPIRATIONAL are design targets ahead of production validation.
The problem
Fabric is made at enormous scale and inspected at human speed. That gap is where the industry’s waste lives.
Making fabric means spinning fibre to a consistent count and twist, weaving or knitting to exact construction, dyeing and finishing to exact shade, fastness and hand, and inspecting for slubs, holes, streaks, stains, barré, skew and width faults, all to buyer spec, fully traceable.
It is unforgiving. A yarn drift, a loom fault, a dye-recipe error or a finishing defect turns into seconds, reprocessing, shade rejects and buyer chargebacks. Dyeing and finishing are craft-bound and enormously water- and energy-hungry. And the whole mill is paced by a colourist and operator workforce that is shrinking faster than it is being replaced.
Most mill managers run blind on real-time yarn quality, fabric defects, shade, chemistry, waste and roll genealogy. The work is high-volume, tolerance-bound, resource-intensive and rate-constrained, which is the exact profile autonomy is for.
Seconds
Slubs, holes, streaks and shade misses are caught at the inspection table, not while the fabric is being made.
Re-dyes
A standing recipe card against many greige suppliers and seasonal water. The miss is paid in water, steam and time.
Water and energy
Most mills know the monthly bill and not the litres per kilogram per shade family.
Audits
A roll’s history reconstructed from spreadsheets and paper lab dips every time a buyer asks.
And the constraint underneath
A senior colourist can look at a bath and know it is running hot. There are fewer of them every year, and no mill has found a way to hire the difference.
The agent roster
Each agent owns a stage of the mill, senses its own signals and actuates its own setpoints. The orchestrator plans across them, escalates on policy, and keeps one record of the whole run.
Spinning, count, twist & yarn quality
Controls draft, twist and speed across ring, rotor and air-jet frames to hold count (Ne), CV%, twist and tenacity inside buyer spec, and predicts end-breaks before they cascade.
Loom & knitting-machine control
Holds warp and weft tension, pick density, let-off and take-up on air-jet, rapier and circular-knit machines so construction stays on spec without broken picks, ends-out, floats or holes.
Dyeing chemistry, recipe & shade
Predicts and doses dye recipes from substrate state, then closes the loop on exhaust curves, temperature ramps, pH and salt so the lot lands on shade first time instead of after two re-dyes.
Finishing chemistry, hand & stability
Controls stenter chemistry, overfeed, residence and temperature to hit hand, GSM, width and dimensional stability, with shrinkage and skew held to buyer tolerance across the roll.
Vision fabric-defect sensing
Line-scan and NIR vision detects and classifies slubs, holes, streaks, stains, floats, barré, skew and width faults in-line at full loom and stenter speed, then maps every fault to roll position.
Colour, fastness & grade optimisation
Spectral models score every roll against the buyer standard (ΔE, metamerism, fastness risk) and sort rolls into shade bands so cutting rooms never mix two shades in one garment.
Yield, waste, water, energy & balancing
Sequences dye lots and balances the line against takt, then allocates water, steam and electricity to cut the mill’s two biggest costs after fibre, reprocessing and utilities.
Roll, beam & doffing automation
Drives doffing, beam changes and roll transport with vision-guided manipulators and AMRs, so the scarce labour on the floor moves from lifting rolls to supervising the run.
Right-first-time, genealogy & traceability
Keeps immutable roll genealogy from bale to bolt and assembles the conformance packet, test methods, chemistry declarations and audit trail, that buyers and auditors demand.
Agent graph
This is the shape of a dye lot on Yarneon, shown as an illustrative scenario rather than a customer run. Ingest and simulation fan out, converge on a colourist approval gate, then dosing, verification, finishing, inspection and release. The accent traces the active path; every node opens in the inspector.

Run timeline
The same scenario run as an ordered timeline: step, status, duration and the tool result behind it. Inspection failed on one roll, the run recovered, replanned the cut and still held the ship date.
Goal: Dye lot DL-4471 · 3,180 kg · 40s combed cotton poplin · shade Indigo 19-4028 TCX · ΔE ≤ 0.8 · due Thu 06:00
Pulls greige genealogy for 14 rolls: yarn lots, loom, greige GSM 138, absorbency and residual size from the prep line.
agent Quality-and-Conformance
result ← 14 rolls · 3,180 kg · mean GSM 138.2 (σ 1.1) · prep OK

agent Dye-and-Color
result ← 2.14% Navy RGB · 0.61% Blue BRF · 0.08% Black B · salt 62 g/L
Recipe deviates >5% from the standing card, so autonomy is capped: the colourist approves, rejects or edits before any dosing. Guardrail policy MILL-02/DYE-APPROVAL.

result ← 1 defect cluster · roll 09 · 33 m affected · class WEFT_STREAK
cuOpt re-plans the cut and rework route: 33 m diverted to seconds, remaining 14,890 m re-sequenced so the buyer’s Thursday ship date still holds.
agent Yield-and-Takt
result ← 33 m to seconds (0.22%) · ship date held
Four-point grading, roll genealogy and the conformance packet (AATCC 61, ISO 105-C06, ZDHC MRSL declaration) are assembled and released to the buyer portal.

Why this matters
A mill does not fail on the good lots. It fails on the lot where the substrate drifted, the recipe card was wrong, and nobody found out until the buyer opened the carton. Yarneon makes that lot legible while it is still in the machine.
Accelerated computing
Line-speed vision, spectral colour science and a fabric-line twin are GPU-essential workloads. Yarneon runs them at the mill edge and trains them centrally.
| Component | Role in the mill |
|---|---|
| Isaac + Jetson | Robotic roll, beam and doffing handling, plus mill-edge inference on inspection and control cells. |
| Metropolis / DeepStream + TensorRT | Line-speed fabric-defect vision pipelines targeting sub-100 ms per-frame decisions. ASPIRATIONAL |
| Holoscan | Sensor fusion across cameras, spectrophotometers, probes, PLC events and meters into one explainable state stream. |
| Omniverse + Replicator / Cosmos | The as-produced fabric twin, and synthetic generation of rare defect, barré and shade-variation cases. |
| cuOpt | Dye-lot sequencing, rework queues, machine assignment and water/energy allocation under hard constraints. |
| Triton + NIM + NeMo | Multi-model serving at the mill edge, plus grounded textile-process and colour reasoning with citations. |
| NVIDIA AI Enterprise | Private and on-prem deployment for groups protecting dye recipes and construction IP. |
Items marked ASPIRATIONAL describe target architecture ahead of full production validation.
Benefits
Equity
Every full-time hire gets equity.
Travel
Field time is part of the job, not an inconvenience.
Hardware
Including a dev appliance with a real GPU on your desk.
Learning
We pay for textile technology courses for engineers new to the industry.
Health
Medical cover arranged for your location.
Time
Mills run three shifts. We do not. On-call is compensated and rotated.
Design-partner programme
Three to five mills, one wedge workflow each, shadow mode first. The sequence comes from our MVP plan and does not change for anyone.
Phase 1
The wedge workflow is connected in shadow mode and the baseline for seconds, re-dyes and waste is measured from the mill’s own data.
Phase 2
The agent recommends yarn, construction and recipe moves and predicts defects and shade. An engineer approves each one, and accuracy is scored in the open.
Phase 3
Low-risk inspection, dye and finishing loops move to bounded auto-control one setpoint at a time. Exceptions escalate to a named person.
Phase 4
Adjacent modules are added within the same mill once the wedge holds its numbers. Publication of results is the mill’s decision.
If you have run a dyehouse, built a vision system that survived a factory, or shipped controls that people trusted, write to us anyway.
