The HTHP (High Temperature High Pressure) Horizontal Tubular Package Yarn Dyeing Machine is an advanced textile dyeing equipment designed for dyeing various types of yarns under high temperature and pressure conditions. This machine is widely used in the textile industry for dyeing materials like cotton, polyester, acrylic, viscose, blends, and other synthetic or natural fibers.
Horizontal Tubular Design:
Compact and space-saving horizontal configuration.
Ensures uniform dye liquor flow across all yarn packages.
Easier loading/unloading and maintenance compared to vertical machines.
High Temperature & High Pressure Operation:
Dyeing temperature: Up to 140C.
Operating pressure: Up to 5 bar (kg/cm).
Enables dyeing of synthetic yarns and blends requiring higher temperatures.
Energy Efficient:
Lower liquor ratio (typically 1:3 to 1:6) for water, energy, and chemical savings.
Optimized pump system reduces power consumption while maintaining liquor circulation efficiency.
Versatility:
Suitable for a wide range of yarn types:
Cone yarn
Hank yarn (with additional attachments)
Loose fibers (with special carriers)
Dyeing of cotton, polyester, acrylic, wool, nylon, viscose, etc.
Dyeing Vessels and Carriers:
Built from high-grade stainless steel (SS316/SS316L) to resist corrosion and pressure.
Various carrier designs available for different yarn formats.
Advanced Control System:
Fully automated PLC-based control panel with touch screen HMI.
Programmable dyeing recipes for precise temperature, pressure, and flow control.
Option for remote monitoring and data logging.
Reversible Flow Pump System:
Ensures even dye penetration from inside-out and outside-in.
Prevents yarn channeling and patchy dyeing.
Safety Features:
Pressure relief valve
Safety interlocks
Emergency stop system
Over-temperature and over-pressure protection
Yarn dyeing in textile mills and dye houses
Suitable for both batch and small-lot production
Ideal for dyeing:
Cotton yarn for knitwear and woven garments
