Product Overview

The KR‑855 benchtop mini stenter is a compact heat‑treatment unit designed for textile dyeing‑and‑finishing laboratories. It simulates the real‑world production‑line stenter process for small‑size fabric swatches. The equipment performs multiple lab‑scale workflows including specimen drying, thermal‑fixing, resin‑baking and curing after padding or coating treatments.

It can work in tandem with a laboratory padder for complete sample processing. Operators evaluate colour‑shift effects of dyeing formulas, test the performance of textile auxiliaries, and optimise resin‑finishing recipes. Both woven fabrics and stretch‑prone knitted textiles can be secured on adjustable bidirectional pin‑plate frames to control warp and weft tension. An optional standalone steam generator can be added to upgrade to the KR‑855A steam‑capable variant.

Core Product Competitive Advantages

1. Full SUS304 Stainless‑Steel Construction for Harsh Lab Environment Main chamber, drawer assembly and internal working components are built from SUS304 stainless‑steel. It resists corrosion caused by chemical auxiliaries, high‑temperature moisture and residual dye liquor, extending service‑life inside dye‑finishing labs.
2. Bidirectional‑Adjustable Pin‑Plate Specimen Frames Two sets of pin‑plate racks support independent warp‑and‑weft tension tuning. It firmly holds woven and knitted fabric samples and reproduces real‑production stretching conditions, avoiding sample shrinkage or distortion during high‑temperature heat‑setting cycles.
3. Circulating Hot‑Air System with Stable Temperature Control Internal circulating‑blower delivers evenly distributed hot‑air flow across the whole working cavity. Temperature accuracy is held within ±2 % across the full working range, eliminating local hot‑spots that would cause uneven finishing results on test swatches.
4. Automatic Feeding‑Retracting with Timing‑Alarm Reminder High‑temperature‑resistant chain‑drive system handles automatic sample loading into heating chamber. Users configure running duration from 10 seconds up to 6 minutes. Once the preset cycle completes, the sample rack automatically ejects and triggers audible alarm to notify lab staff.
5. Modular Expandable Configuration Standard KR‑855 unit runs electric‑heat drying and fixing only. Users can add an external independent steam‑generator assembly to realise steaming‑ageing functions and upgrade to KR‑855A version, matching evolving laboratory‑test requirements without replacing the main machine body.

Standard Complete Test Operating Workflow

1. Pre‑Test Preparation Position the unit on level lab floor, complete power‑on startup. Mount fabric swatch onto bidirectional pin‑plate frame, adjust warp‑weft stretching tension according to target‑process parameters. Set target temperature and heat‑holding duration on front‑panel controls. Allow the cavity to pre‑heat until stable set‑point temperature is reached.
2. Automatic Sample Feeding Place loaded pin‑plate rack on the inlet station. Activate start‑command; chain‑transport mechanism automatically pulls specimen into closed heating chamber.
3. Heat‑Setting & Drying Process Circulating hot‑air circulates inside the cavity to perform drying, curing or thermal‑fixing treatment for the fabric sample. System counts‑down the configured holding‑time.
4. Auto‑Eject & Completion Alert Upon finishing timing sequence, the pin‑plate sample‑frame is automatically pushed outward, accompanied by audible reminder tone. Take‑out processed fabric swatch for subsequent colour‑assessment or physical‑property testing.
5. Post‑Test Tidying Start built‑in cooling‑fan to lower internal cavity temperature for next‑group testing. Clear fibre debris and chemical residues from pin‑plate needles and drawer‑chamber. Power‑off equipment after full cooling. Conduct regular inspection for heating‑element and chain‑drive condition.
