A circular pile knitting project is not one generic loop-making job. Terry loops, raised fleece, patterned pile and cut high-pile surfaces place different demands on yarn allocation, knitting elements, take-down and finishing. Start with the finished face and work backward; that keeps the machine discussion tied to a fabric the mill can inspect.
The three retained Kunyuan images show relevant pile-machine and knitting-area references, not a promise that one arrangement covers every pile route. The exact pile mechanism, pile height range, gauge, feeders and change parts must be confirmed on the model sheet and proved with the buyer's yarn.
Describe whether the required surface stays as a loop, is raised after knitting, is cut during loop formation, or uses electronic selection to place pile only in chosen areas. Also record the backing structure. Two samples can look similarly soft in a showroom yet need different knitting elements and finishing sequences.
Separate ground yarn, pile yarn and any binding or effect yarn in the yarn plan. For each system, note material, count, twist, package form and acceptable variation. A pile fault can originate in the pile feed while the backing remains stable; one combined yarn description makes that distinction impossible during a trial.
Check package build, unwinding direction, joins and contamination before threading. Set a repeatable starting tension for each yarn role instead of copying one value to every feed. Keep one labelled package from the approved trial so a later complaint can be compared with the material actually used.
Run slowly enough to observe yarn presentation, needle and sinker movement, loop release and take-down response. The useful setting is not the longest possible loop; it is the loop that remains secure in the backing and survives the planned dyeing, raising, shearing or cutting route.
Mark machine direction, start time and roll position. Compare pile height, coverage, backing visibility, vertical lines and repeating feed marks under consistent light. Do not cut the sample away from its label; the machine position is part of the diagnosis.
Send a traceable strip through the actual finishing route. Raising can open loops; shearing changes surface height; dyeing and heat can alter hand, width and dimensional response. Approving only greige appearance leaves the main commercial risk untested.
Compare usable width, finished weight, pile appearance, backing stability, shedding or fibre loss where relevant, and the defect limit agreed with the customer. Record the final machine and finishing settings together. The knitting department cannot close a surface claim if the finishing history is missing.
Settings interact. More pile-yarn delivery without matching loop formation and take-down can create loose, uneven or unstable surface loops. Higher speed may change heat, lint load and yarn behaviour. The trial sheet should therefore capture one controlled change and its fabric response.
| Process variable | What the operator observes | Evidence kept with the roll |
|---|---|---|
| Pile and ground yarn delivery | Loop height, coverage, backing visibility and tension events | Feed map, yarn labels and one marked sample |
| Knitting elements and cam route | Loop capture, release, vertical lines and damaged elements | Part designation, track position and service note |
| Take-down and fabric handling | Course density, surface distortion and roll build | Setting record, width and roll-position map |
| Cleaning and lubrication | Lint accumulation, oil marks, heat and restart quality | Product used, interval, action and post-clean sample |
Split the approved greige length into labelled pieces only after the full roll position is recorded. One piece remains as greige evidence; the others follow each finishing route under review. When the finished face changes, the team can then distinguish a knitting variation from a raising, cutting, shearing or heat-setting variation.
Applications can share a machine family without sharing one acceptance recipe. List every planned fabric in the RFQ and identify which styles need different change parts, yarn maps or separate trials.
Not automatically. Those labels cover different loop-forming and finishing routes. Confirm the exact machine arrangement, knitting elements, change parts and finishing trial for each planned fabric.
Approve a labelled greige sample for knitting stability, then approve the same traceable material after the intended finishing route. Keep both because either stage can create the visible difference.
Use the finished-surface target and a measurable inspection method. The achievable range depends on the machine configuration, yarn, backing, take-down and finishing; confirm it in the model-specific trial.
A repeating thin line, sudden backing visibility, loop-height drift, yarn-tension event or change in lint/oil pattern deserves a marked sample before settings are disturbed.
Send the physical fabric or construction, separate yarn data, greige and finished targets, usable width, finishing route, defect limits and the production schedule to be demonstrated.
A credible pile-fabric project connects five records: yarn plan, machine configuration, greige roll map, finishing route and finished inspection. When those records agree, the buyer can compare machines on repeatable fabric rather than on a broad pile label.
Use the related pile fabric circular knitting machine range to identify a starting machine family, then ask for a configuration and trial written around the exact pile route.
