What types of fibers are suitable for high temperature and high pressure jigger dyeing machine?

High temperature and high pressure jigger dyeing machine is a key equipment for processing specific fibers in the textile printing and dyeing industry. Its core is to create a closed environment with high temperature (usually over 100℃, up to 130℃) and high pressure (higher than normal pressure). This special working condition is most suitable for those fiber types that are difficult to color at normal temperature and pressure, or require special conditions to obtain good dyeing effects.

Polyester (polyester fiber) among synthetic fibers is the most typical application object of high temperature and high pressure jigger dyeing machine. The molecular structure of polyester fiber is tight at room temperature, and it is difficult for dye molecules to penetrate. Only in the high temperature environment of high temperature and high pressure jigger dyeing machine, the molecular chain segments of polyester fiber will fully move, and the structure will become loose, providing a good diffusion channel for dye molecules, thereby achieving high saturation and excellent color fastness. Nylon (nylon) also benefits from this equipment. It can obtain uniform, bright and fast color when processed in high temperature and high pressure jigger dyeing machine, especially for deep and thick color numbers.

In addition to these synthetic fibers, some natural fibers such as cotton and its blended fabrics sometimes also need to use high temperature and high pressure jigger dyeing machines, especially when dyeing polyester-cotton blended fabrics (TC fabrics) or interwoven fabrics, the high temperature dyeing requirements of the polyester component need to be met in the high temperature and high pressure jigger dyeing machine. In addition, some functional fibers that have special requirements for temperature and pressure (such as some high-performance flame-retardant fibers) or industrial fibers that require extremely high color fastness requirements also often use high temperature and high pressure jigger dyeing machine processes.

However, protein fibers such as wool and silk or some viscose fibers that are extremely sensitive to high temperatures are not suitable for processing in such equipment, and high temperature and high pressure can easily cause damage to them. In general, high temperature and high pressure jigger dyeing machines mainly serve synthetic fibers such as polyester and nylon and their blended fabrics. Through the unique high temperature and high pressure environment, they can achieve deep penetration and lasting color fixation that traditional methods cannot achieve, and have irreplaceable process value in improving the dyeing quality of synthetic fibers.
