An HTHP (High-Temperature High-Pressure) dyeing machine is a type of equipment used in the textile industry to dye fabrics, yarns, and other textile materials. It operates by heating water to a high temperature (usually between 120 degree C to 140 degree C) and adding a dye solution to it under high pressure (usually between 3 to 5 bar). This high temperature and high-pressure combination allows for the dye to penetrate deep into the fibers of the textile material, resulting in a more uniform and vibrant color.HTHP dyeing machines are typically made of stainless steel or other durable materials and come in various sizes, with capacities ranging from 100 kg to 5000 kg. They are designed to handle a wide range of materials, including cotton, polyester, silk, and wool, among others.
