Terry Jacquard Circular Knitting Machine

Choose the loop before choosing the option list

Terry jacquard fabric combines a patterned structure with a controlled loop surface. The first sample should define which side carries the loop, the target loop height, ground coverage, yarn allocation and the finishing route. The archived Kunyuan record lists TM/PM, 18–52 inch diameter, 7G–28G, 36F–104F for XF-TM and 28F–84F for XF-PM. It also records optional loop sinkers from 1.5 mm to 5.0 mm and knit, tuck and miss cam options.

These ranges are broader than the computerized terry-jacquard record on ID 8. The archived page does not establish that every TM/PM configuration uses the same computerized controller, so the buyer should ask exactly how jacquard selection is performed and what pattern/change parts are included. This prevents two related product names from being treated as interchangeable.

Loop sinkers change the starting geometry

The sinker choice influences the loop that leaves the knitting zone, but it does not by itself guarantee the finished pile height. Yarn shrinkage, tension, take-down and later washing, raising or shearing can change the surface. A 1.5 mm option and a 5.0 mm option therefore need separate fabric trials with the intended yarn and finish.

Knit, tuck and miss cams add structural choices. Ask Kunyuan to mark which cams are standard, which are optional and how they correspond to the submitted fabric. For TM and PM, request a configuration diagram showing ground/pile yarn positions, feeder count and the selected loop sinker.

TM/PM comparison record

Inspect the loop in more than one state

Run the planned ground and pile yarns, label the TM/PM setup, sinker, cam selection, speed and take-down, and take samples across the roll. On greige fabric, inspect missed loops, uneven loop height, ground coverage, needle lines and repeated feeder marks. Measure width and weight at agreed positions.

Process part of the same sample through the real finishing route. Then compare loop openness, surface direction, flattened areas, pattern definition and dimensional change. If shearing or raising is involved, name the process and acceptance method; the knitting machine cannot be credited with the final surface without that downstream evidence.

Keep options from becoming undocumented adjustments

Store the cam and sinker set used for each approved construction. After a change, record the parts, yarn path and first accepted roll rather than relying on operator memory. Watch pile-yarn delivery, stop motions, lint, sinker condition and take-down during production. A defect that repeats with the pattern may have a selection/cam cause; a fixed circumference line points to a mechanical location.

The old speed guide lists 15–25 RPM for examples such as 24, 30 and 34 inch machines. Do not combine that guide with an unrelated feeder or gauge. Confirm the exact offered configuration and reduce speed if loop control or pattern definition begins to move. Isolate the machine before sinker, cam or needle work.
