Scorching is the process of rapidly passing a fabric width through flames or across a hot metal surface to burn off the surface fuzz, resulting in a smooth and clean fabric surface to prevent defects during subsequent processing.

How to singe? Singeing is a process that involves passing fabric through flames or across a hot metal surface to remove the fluffy fibers on the fabric surface, achieving a smooth and lustrous finish. The fluffy fibers, being close to the flame and in a loose state, can quickly heat up and ignite. The fabric itself, however, is denser and thicker, and farther from the flame, so it heats up more slowly and leaves the flame or hot metal surface before reaching the ignition point. This principle of different heating rates between the fabric and the fluffy fibers ensures that only the surface fibers are singed without damaging the fabric. During singeing, different fiber materials require different singeing temperatures, so it's crucial to understand the thermal properties of various fibers. Caution: Insufficient heat (under-singeing) can result in incomplete removal of the fluffy fibers, which may appear spherical and cause color spots during dyeing. Overheating or slow speed (over-singeing) can cause the fabric to shrink, resulting in wrinkles, a stiff feel, and shrinkage of the width. Key points: High temperature (beneficial for singeing) and rapid speed (protects the fabric) are essential to ensure that singeing only affects the fluffy fibers without damaging the fabric itself.
