The working mechanism of the AS - HP is both innovative and effective. Yarns are carefully placed inside a sealed cylinder, where compressed air is injected to a specific pressure. In the initial stage, this high - pressure air squeezes out the majority of the moisture present in the wet yarn balls. Subsequently, a fan - driven stream of heated, high - temperature and high - pressure air penetrates the yarn. This causes the remaining moisture to evaporate, and within the closed - loop system of the machine, the moisture - laden air circulates. The moisture is then condensed and drained away through a cooler, a process that continues until the yarn is completely dry. This closed - loop operation not only ensures maximum efficiency but also minimizes the risk of external contamination, making it ideal for applications where product purity is of utmost importance.
The AS - HP's performance is not only about speed but also about quality. By precisely controlling the pressure and temperature, it ensures that the drying process is gentle on the materials, preventing damage to the yarn's structure. This is particularly important for delicate or high - value yarns, where maintaining the integrity of the material is as crucial as removing the moisture.
Beyond the textile industry, the AS - HP can also find applications in other sectors where rapid and efficient drying of materials is required. For example, in the production of certain industrial materials or even in some food - related applications where moisture removal from specific raw materials is a critical step.
In the dynamic realm of the textile industry, the pursuit of advanced and efficient dyeing technologies is relentless. The demand for equipment that can handle a diverse range of fabrics, offer cost - effective solutions, and produce top - notch dyed products has led to the emergence of a groundbreaking innovation - the AS - MULTI - FLOW series of high - temperature multi - flow full - mode dyeing machines.
This new - generation dyeing machine stands out with its unique ability to operate in three distinct modes: pure air - flow dyeing mode, pure over - flow dyeing mode, and air - over - flow mixed dyeing mode. This versatility allows it to cater to a wide array of dyeing cloth types, making it a one - stop solution for textile manufacturers with varied product lines.
One of the most remarkable features of the AS - MULTI - FLOW series is its carefully engineered circulation system, which combines airflow and liquid flow in a superimposed manner. This design enables the fabric to move smoothly at an impressively low bath ratio of 1:3. By reducing the amount of water and dye required for each batch, the machine not only cuts down on production costs but also contributes significantly to environmental sustainability.
The fabric lifting system of the AS - MULTI - FLOW series is another area where innovation shines. The seamless integration of the double - stage nozzle and the guide pipe allows the fabric to reach a running speed of up to 400 m/min. This high - speed operation is crucial as it can meet the dyeing process requirements of different fabrics, from delicate and lightweight materials to more robust and heavy - duty textiles.
When it comes to technical specifications, the main cylinder of the AS - MULTI - FLOW series is a powerhouse. It can achieve a maximum fabric speed of 400 m/min, ensuring high - volume production. The maximum working pressure of 0.4 Mpa and a maximum operating temperature of 135°C make it suitable for high - temperature dyeing processes, which are often required for synthetic and blended fabrics. The heating rate is well - calibrated, with an average of 5°C/min from 25°C to 100°C and a specific rate for the 100°C - 130°C range (with dry saturated steam pressure at 0.7 MPa). The cooling rate is also efficient, dropping from 130°C to 100°C at an average of 3°C/min and from 100°C to 85°C at 2°C/min (with cooling water pressure at 0.3 Mpa and a temperature range of 5°C - 10°C).
The liquor ratio of 1:3 is a game - changer in the industry, as it represents a significant reduction compared to traditional dyeing machines. This low ratio not only saves resources but also results in more concentrated dyeing, leading to more vibrant and long - lasting colors.
For added flexibility, the machine offers an optional multi - function reserve cylinder. With a maximum operating temperature of 85°C and a maximum working pressure at atmospheric level, this reserve cylinder can handle specific dyeing processes or act as a backup during peak production times. Its heating rate, averaging 4°C/min from 25°C to 85°C (with dry saturated steam pressure at 0.7 MPa), and a capacity of about 1:4 - 5 of the main cylinder, make it a valuable addition to the AS - MULTI - FLOW series.
The AS - MULTI - FLOW series of high - temperature multi - flow full - mode dyeing machines is set to revolutionize the textile dyeing process. By offering a wide range of suitable fabrics, low production costs, and top - tier quality of dyed fabrics, it is poised to become the industry standard for textile manufacturers worldwide. As the industry continues to evolve towards more sustainable and efficient practices, the AS - MULTI - FLOW series is leading the way, providing a solution that meets the demands of both today's market and the future of textile manufacturing.

Differences Between High-Temperature High-Pressure Dyeing Machines and Normal-Temperature Atmospheric-Pressure Dyeing Machines
1. Different Working Conditions
High-temperature high-pressure dyeing machines:The working temperature is usually above 100℃ (commonly 120-130℃, or even higher), and the working pressure is higher than atmospheric pressure (generally 0.2-0.5MPa, depending on specific temperature requirements). A sealed design is required to maintain the high-temperature and high-pressure environment.
Normal-temperature atmospheric-pressure dyeing machines:The working temperature is usually from room temperature to 100℃ (mostly the boiling temperature, i.e., 100℃), and the pressure is atmospheric pressure (1 standard atmosphere). There is no need for a sealed and pressure-resistant design; even an open or simply sealed structure can be adopted.
2. Different Applicable Fibers and Dyes
High-temperature high-pressure dyeing machines:They are mainly used for synthetic fibers (such as polyester, nylon, acrylic, etc.). These fibers have a dense structure and strong hydrophobicity, making it difficult for dyes to penetrate at normal temperature. High temperatures (around 130℃) are needed to intensify the movement of fiber molecular chains and increase the gaps, and they are used in conjunction with disperse dyes (special for polyester), acid dyes (special for nylon), etc., to achieve dyeing.
Normal-temperature atmospheric-pressure dyeing machines:They are suitable for natural fibers (cotton,flax,wool, silk, etc.) and some regenerated fibers (such as viscose). Natural fibers have strong hydrophilicity. At normal temperature or boiling (100℃), reactive dyes (for cotton,flax), acid dyes (for wool/silk), etc., can complete dyeing through penetration, reaction, or adsorption without the need for high temperature and high pressure.
