R-3 Automatic Fabric Sample Dryer and Stenter

Product Introduction
The R-3 Automatic Fabric Sample Dryer and Stenter is a compact textile laboratory machine designed for drying, heat setting, resin finishing, pad dyeing baking, and thermosetting tests on fabric samples.
With a test fabric size of 300 × 400 mm and an effective working size of 250 × 350 mm, the R-3 is suitable for small-sample process development in dyeing and finishing laboratories. Its hot-air circulation system provides adjustable upper and lower airflow, while the digital temperature control system supports stable heating from 20°C to 250°C.
The machine is manufactured from high-quality SUS304 stainless steel and features preset timing, automatic cycle completion, audible notification, and a two-group bidirectional stretching pin-frame system.

Performance Features
• Designed for textile dyeing and finishing laboratory applications.
• Supports fabric drying, heat setting, resin processing baking, pad dyeing baking, and thermosetting tests.
• Constructed from corrosion-resistant SUS304 stainless steel.
• Hot-air circulation system with adjustable upper and lower airflow.
• Digital automatic temperature control with temperature accuracy of approximately ±2%.
• Wide working temperature range from 20°C to 250°C.
• Preset heating and holding time from 10 seconds to 6 minutes.
• Automatically exits the working cycle and provides an audible alarm when the process is completed.
• Equipped with a stainless steel fan wheel and 180 W fan motor.
• Includes two groups of bidirectional stretching needle boards for fabric fixing.
• Available in vertical and horizontal configurations.
• Compact design suitable for laboratory and small-sample testing.

Working Principle
The R-3 automatic fabric sample dryer uses an electric heating system to generate hot air. The fan circulates the heated air through the working chamber, allowing heat to transfer evenly to the fabric sample.
The fabric is fixed on the bidirectional stretching pin frame to maintain the required width and shape during drying or heat setting. The digital temperature controller regulates the heating system according to the preset temperature, while the adjustable upper and lower airflow helps improve drying and finishing uniformity.
The operator can preset the processing time between 10 seconds and 6 minutes. After the cycle is completed, the machine automatically exits the working process and activates an audible alarm.
