Jet Dyeing
Jet dyeing is one of the most common methods for dyeing fabrics, particularly used for synthetic and delicate fabrics. The fabric is treated in a high-pressure dyeing machine where dye is pumped through a jet stream that flows over the fabric. The fabric is continuously moved through the dye bath, ensuring an even application of color. This method is ideal for materials that require a gentle, thorough dyeing process.
Spotting
Spotting refers to the process of removing any stains or unwanted marks that may have appeared on the fabric before or during dyeing. It is a necessary pre-treatment process, especially when dealing with fabrics that are already colored or have been exposed to dirt during manufacturing.
Jigger Dyeing
Jigger dyeing is a technique typically used for cotton fabrics and is effective for dyeing large quantities of fabric. In this method, fabric is passed through a dye bath in a continuous motion using a jigger machine, which consists of two rollers through which the fabric is pulled and immersed in the dye solution. Ideal for larger volumes of fabric and ensures uniform dye penetration, particularly for woven fabrics.
Staining (or Stainte)
In fabric dyeing, staining or stainte refers to the process of introducing color to the fabric in a controlled and intentional manner, usually involving minor imperfections or areas that need more color intensity. Staining is often done to create subtle color changes or texture on the fabric surface, like creating tie-dye effects or highlights. Can be achieved through localized application or by spraying, blotting, or using different dye techniques like hand-dyeing.
Calendering
Calendering is a finishing process that involves passing the dyed fabric through heated rollers to smooth, compact, and sometimes give it a glossy finish. Calendering helps to improve the appearance, texture, and feel of the fabric. It is typically done after dyeing to improve its surface quality.
Deca (Decatizing)
Decatizing, often referred to as Deca, is a finishing process applied to wool fabrics to enhance their texture and prevent shrinkage. This involves treating the fabric with steam and heat under controlled conditions to improve its appearance, feel, and stability. The fabric is fed through a heated chamber where steam and pressure are applied, which helps to set the fabric and stabilize the fibers.
Folding
Folding is the final step in the fabric dyeing process, where the dyed and finished fabric is carefully folded and prepared for shipping, storage, or further processing. This step is essential to ensure that the fabric remains in pristine condition during transportation and handling. After drying and finishing, the fabric is folded neatly either by hand or using folding machines. To prepare the fabric for easy storage and to minimize any potential damage or wrinkles that could affect its appearance or usability.
