As a kind of yarn with unique color mixing effect woven from different kinds of fibers, black has a good three-dimensional effect and texture. It can effectively control the color difference without polluting the environment. Its soft color is pleasing to the eye. So more and more people use it in their clothing products. Its one-color spinning can achieve the hazy three-dimensional effect and texture that cannot be achieved by white blank dyeing. High Tenacity Polyester Filament Bonded Twisted Yarn is non-staining and can control chromatic aberration. Therefore, colored spun yarns with soft and fashionable colors and flexible production of small batches and multiple varieties are increasingly used in Chinese clothing products. High Tenacity Polyester Filament Bonded Twisted Yarn adopts the new process of "dyeing first, spinning later", which shortens the production process and reduces the production cost of downstream processing enterprises, and has higher added value. The traditional process of "post-dyeing", High Tenacity Polyester Filament Bonded Twisted Yarn product performance is better than other textile products, has strong market competitiveness and good market prospects.

High Tenacity Polyester Filament Bonded Twisted Yarn dyes the yarn. There are three methods of conventional yarn dyeing:
① Twisted yarn dyeing - immersing loose High Tenacity Polyester Filament Bonded Twisted Yarn in a special dye vat, which is a costly dyeing method;
②Cheese dyeing - The High Tenacity Polyester Filament Bonded Twisted Yarn of bobbin dyeing is wound on a perforated bobbin, and then many bobbins are put into the dyeing vat, and the dye liquor circulates, and the fluffy effect and softness are not as good as skein dyeing.
③ Warp beam dyeing - is a large-scale package dyeing. Before weaving is made, warp beams (warping) must be made, and the entire warp beams are dyed with High Tenacity Polyester Filament Bonded Twisted Yarn, such as a combined sizing and dyeing machine. Dyed with warp yarn bundles. Because it is a warp beam, it is mostly suitable for woven dyeing. But with the emergence of warp beam doffing, we can doff the yarn on the warp beam after dyeing into package yarn. This dyed yarn can be used in a wider range. For example, the reduction dyeing method mostly used in indigo dyeing, only using Beam dyeing can be a good solution, if there is no beam doffing, it is difficult to achieve.
