Computerized Terry Jacquard Circular Knitting Machine

A pattern file is only half of the job

On computerized terry jacquard fabric, the design must arrive at the correct needle while the ground and pile yarns continue forming stable loops. A clear screen preview can still produce a weak fabric if yarn allocation, loop formation or take-down is wrong. The archived Kunyuan page records a 30–38 inch diameter range, 12G–24G, 36F/54F and a 14–18 RPM reference. It also names reverse (polar) terry and velour/ordinary terry configurations.

This product fits patterned towels, bath textiles, sweater linings, pajamas and similar terry programs when the mill needs repeatable digital designs. The quotation should say which controller and selection system are offered, which file format is accepted, and whether the buyer receives editable pattern files. “Computerized” should not be used as a substitute for those details.

Follow the design from file to loop

Begin with a pattern repeat, color allocation and a small reference image. The design is converted into selection instructions; the machine then has to feed the right yarns and form the intended loop at each selected position. Ground coverage supports the fabric, while pile-yarn delivery and sinker/loop settings influence surface height and definition. Reverse terry and ordinary terry should be trialled separately because the visible face, handling and finishing checks are not identical.

Power stability matters because an interrupted controller or lost file revision can stop production or create an undocumented restart. Record the file name, revision, machine settings and yarn lots with the sample. A multilingual screen may help operators, but the useful question is whether the team can load, back up and restore an approved program without changing the result.

What to close before pattern approval

Run a design that can expose errors

Do not approve the machine with a large plain block. Use a representative design containing edges, small motifs, color changes and longer continuous areas. Those features make missed selections, shifted registration and unstable loop formation easier to see. Inspect the first metres after loading, then sample again after the machine has reached a stable run.

Check pattern registration, edge sharpness, repeated bars, missing loops, loop height and the condition of the back. Compare width and weight at agreed points. After the intended finishing process, look again for distorted motifs, flattened loops or a change in surface direction. Keep the rejected and approved pieces together; they are more useful to operators than a general instruction to “ensure quality.”

Protect the program and the knitting zone

Back up pattern files before edits and control who can overwrite the approved revision. At the machine, watch selector response, pile and ground yarn tension, yarn stops, lint around the knitting zone and roll build. A defect that repeats at the design repeat may point to the file or selection logic; one fixed line around the circumference is more likely to need a feeder, needle or mechanical location check.

Use the 14–18 RPM archive value as a reference, not a target to reach before fabric approval. Increase speed only after the pattern and loop structure stay stable. Isolate the machine before cleaning or component work, and follow the supplied service procedure for the controller and the knitting mechanism.
