38-Inch 24G Double Jersey Circular Knitting Machine

A fixed configuration needs a fixed fabric brief

This product page describes a specific 38-inch, 24G and 84-feeder double-jersey configuration rather than a broad machine family. The archived record also shows a 20 RPM reference and a 2-ton weight field. The useful sales conversation is therefore concrete: which double-knit structure, yarn and finished width/weight will be produced on this exact setup?

The old page mentions sportswear, underwear and ribbed fabric. These are possible directions, not guaranteed outputs. Submit the construction, yarn/elastane allocation, desired hand, stretch/recovery and finishing route. The supplier should explain how cylinder/dial timing, feeder plan and take-down will be set for that sample.

Fine enough to show small errors

At 24G, needle condition, yarn consistency and timing errors can produce visible lines or uneven loop formation. Eighty-four feeders increase the need for organized yarn routing and feeder-level defect tracing. A stable trial should therefore be sampled across time and width, not approved from one short swatch.

Inspect both fabric faces. An attractive face can hide a weak reverse, floats or a cylinder/dial imbalance. If elastane is used, identify its feeder positions and measure recovery after the real finishing process.

Fixed-model approval sheet

Inspect the roll, not only the machine

Run production-representative yarn until temperature, lubrication and take-down have reached a normal operating state. Record stops and interventions. Examine for needle lines, barre, holes, repeating feeder marks, oil contamination and edge/roll problems. Measure width, weight and stretch at agreed intervals.

Finish a labelled sample through the intended dyeing, compaction or heat-setting route. Check shrinkage, skew, hand and recovery again. If the buyer needs moisture management or another function, test it through the appropriate fabric method; do not infer it from polyester or yarn names alone.

Maintenance at 24G and 84 feeds

Keep feeder positions identifiable and store defect maps by circumference location. Inspect needle and dial condition, yarn guides, stop motions, lubrication and take-down. A line fixed at one position deserves mechanical inspection; a band that follows a yarn package change may point to yarn or tension.

Follow the supplied cleaning/lubrication schedule and isolate the machine before work in either needle bed. Keep the accepted settings with the yarn lot so another shift can reproduce the result.

Plan around roll and floor handling

A 38-inch machine and its finished rolls must fit the mill’s actual aisle, lifting and downstream handling route. Confirm the machine footprint, service clearance, electrical supply and the weight/diameter expected for a normal roll. Do not confuse the archived 2-ton machine field with fabric-roll capacity; Kunyuan should state both values separately in the technical file.

Before shipment, agree which gauges, feeders, guards, lubrication items, tools and critical spares are included. During commissioning, let the buyer’s operators repeat the inspection and doffing procedure. A supplier demonstration is less useful if the local team cannot reproduce the same two-sided fabric and roll condition on the next shift.
