The SGR jigger dyeing machine for acrylic fabric boasts outstanding performance, covering complete specifications ranging from small-batch units to large-capacity dyeing equipment. It comes with four mainstream design variants classified by fabric roll diameters: φ680mm, φ800mm, φ1000mm and φ1200mm. Its external shell adopts a high-temperature high-pressure cylinder structure, supporting a working pressure of 3BAR and a maximum operating temperature of 140°C. Two φ150mm viewing windows are fitted on the operation side, alongside a safety interlock switch for pressure vessel opening. Equipped with expandable functional configurations identical to atmospheric jigger dyeing machines, this equipment collects condensate water at the cylinder bottom, which is then drained automatically via an automatic drain valve.
Product Composition
1. Dye Vat: Constructed from 316L/304 stainless steel; corrosion-resistant; holds the dye liquor.
2. Main Rollers: Support the fabric and drive its reciprocating movement; equipped with a variable-frequency drive (VFD) system.
3. Guide Rollers: Guide the fabric smoothly through the dye vat.
4. Tension Control System: Mechanical or electronic tension adjustment to maintain constant fabric tension.
5. Temperature Control System: PT100 temperature sensor combined with automatic control for precise heating and temperature maintenance.
6. Dye Liquor Circulation System: Ensures uniform mixing of the dye liquor and consistent temperature distribution.
7. Dosing System (Dosing Tank): Automatically measures and adds dyes and auxiliaries.
8. PLC Touchscreen Control Panel: Programmable interface for storing process recipes, automatic process recognition, and alarm functions.
9. Inspection Window: Allows for visual monitoring of the dyeing process while minimizing heat loss.
10. Automatic Forward/Reverse System: Enables the fabric to move back and forth within the dye vat.
