This method is ideal for producing printed or patterned elastic tapes with sharp detail and high repeatability. It's fast, efficient, and commonly used in decorative trim production.
• Padding (Impregnation): The fabric is passed through a trough containing dye solution and then squeezed between rollers (padders) to ensure even saturation and remove excess liquor. The padded fabric then goes through steam or dry heat to fix the dye. This is one of the most common methods for solid-color dyeing of cotton and synthetic blends.
• Spray Dyeing / Application Barge: Dye is sprayed onto the fabric surface using nozzles, allowing for localized coloring, gradient effects, or minimal chemical usage. This method reduces wastewater and is increasingly used for eco-friendly production.
• Foam Dyeing: A low-liquor technique where dye is delivered in a foam state using air as a carrier medium. This method drastically reduces water consumption (by up to 80%) and energy use, making it a sustainable option for dyeing delicate or moisture-sensitive fabrics like elastic tapes.
• Jet Dyeing (for hanks or loose yarns): While typically associated with batch systems, jet-assisted continuous dyeing uses high-velocity dye jets to circulate color through fabric under controlled tension. It’s effective for synthetic fibers like nylon and polyester, offering deep penetration and excellent color uniformity.

Modern continuous dyeing lines often combine multiple methods (e.g., padding followed by steaming) to achieve superior dye fixation and fabric performance. The choice of method depends on factors such as fiber type, desired color depth, environmental regulations, and production scale.
