The heat-setting machine is designed to stabilize the Lycra content within knitted fabrics at high temperatures. By achieving stabilization prior to dyeing, the machine prevents stresses that might otherwise occur in fabrics made from blended yarns, ensuring the fabric maintains its structural integrity throughout the dyeing process. To achieve the desired fabric weight and dimensional stability (minimizing shrinkage in both width and length) after dyeing, the fabric width can be adjusted to the required specifications. The tubular fabric heat-setting machine is a response to the market demand for "maximum quality at minimum price," driven by rapidly intensifying global competition in recent years. It offers a brand-new alternative to the traditional open-width heat-setting process performed on stenter frames, helping to reduce costs, eliminate waste, and shorten production times. The only difference distinguishing this machine from a stenter is its ability to heat-set the fabric in its tubular form without cutting it; in terms of operational principles and heat-setting characteristics, it functions identically.
