Dyeing is the process of adding color to textile products like fibers, yarns, and fabrics. Dyes are obtained from flowers, nuts, berries and other forms of vegetables and plants as well as from animal and mineral sources. These are known as natural dyes. The other class of dyes is known as synthetic dyes. These are based on a particular type of chemical composition.

Yarn dyeing method: Yarn (including filament) has been dyed for nearly a thousand years, Textiles may be dyed at any stage of their development from fibre into fabric or certain garments.GEster simply sorted out the dyeing method.

A. SKEIN DYEING

The spun yarn or filament is transformed into a skein framed together on the spinning machine, and then the dyeing method of dip dyeing in various forms of dyeing machine is skein dyeing.

B. CHEESE YARN DYEING

Yarn wound on spools, cones, or similar units and then dyed is referred to as package-dyed yarn. The packages of yarn are stacked on perforated rods in a rack and then immersed in a tank wherein the dye is forced outward from the rods under pressure through the spools and then back through the packages toward the center to penetrate the entire yarn as thoroughly as possible. Most carded and combed cotton that is used for knitted outerwear.

C. WARP BEAM DYEING

According to the requirements of the hue and quantity of the warp yarns of the colored fabric, the raw yarn is wound on a perforated coil on the loose warping machine to form a loose warp beam, and then it is installed. It is placed on the yarn carrier of the machine and placed in the warp beam dyeing machine. With the function of the main pump, the dye solution is circulated between the warp beam yarns or fibers to achieve dip dyeing to obtain a uniform color warp yarn. The method is called Warp beam dyeing.

D.PIECE DYEING

The great bulk of dyed fabric on the market is dyed in the piece. This method gives manufacturers maximum flexibility for their inventories to meet large or small demands for a given color as fashion requires. Where yardage warrants it, fabrics are dyed in continuous range machines. Small lots of fabrics of all fibres are dyed in batches. Piece dyeing is thoroughly satisfactory as regards levelness, penetration, and overall fastness, as summing that the proper dyes have been used.

E. YARN BUNDLE PAD DYEING

This is also a special dyeing method for denim warp yarns. The dyeing process is to bundle 400-500 raw yarns into a ball, and then several bundles (such as 12 bundles, 18 bundles, 24 bundles, 36 bundles) of yarns are dyed in multiple The tank is repeatedly dipped, rolled, and ventilated for many times to realize the indigo dyeing, and then divide the warp and sizing. Acrylic tow can also be pad dyed.

F. SPECIAL DYEING METHOD OF YARN

Like fabrics, yarns also have partial dyeing, such as printing, section dyeing, tie dyeing, printing, discharge dyeing, gradation and so on.
