1. Unique color
The color of yarn spun is a fiber melange style, which is different from the pure dyeing of natural yarn or natural cloth. The raw material of color spinning contains at least one kind of colored fiber, which is formed by the full mixing of fibers of different colors in spinning. Therefore, the fabric composed of dyed yarn can present the effect of "spatial mixing" and has a change of layers.
2. Low carbon and environmental protection
Dyed spinning reverses the traditional spinning and then dyeing process, which is to dye the fibers first, and then blend and spin. However, most of the dyed fiber products are not all dyed fibers, and 40%-50% of the raw materials of the dyed yarn are natural fibers, and only part of the dyeing is used. Therefore, it is relatively more energy-saving and environmentally friendly.
Natural fiber has two functions as a raw material for color spinning: one is as a color (white); The second is to adjust the depth of all color spinning products.
For example, the common light-colored cotton and linen gray yarn generally accounts for only about 10% of the dyed cotton, that is, about 90% of the cotton fibers are undyed and natural.
In particular, if the colored fibers in the yarn-dyed products are chemical fibers, then its production process can be completely free of pollution emissions. For example, some colored chemical fibers use the "dope coloring" technology to add masterbatches in the spinning process, and the production process is pollution-free and zero-emission.
3. Dyeing advantages
The traditional "spinning first and then dyeing" process, because of the different chemical properties, makes the fiber dyeing performance also different, which brings trouble to the dyeing of yarn and fabric after blending. The color spinning adopts the process of "dyeing first, then spinning", which just solves the problem of color matching of heterosexual fiber blending.
Because the dyeing process refers to the pre-spinning process, no matter what kind of material fiber: natural, recycled, synthetic; No matter what kind of dyeing process is required: high-temperature and high-pressure dyeing, or normal temperature and pressure dyeing; Regardless of the type of dye: reactive, dispersed, direct, reduced ......, they can be broken individually, dyed separately and then perfectly combined. As a result, dyeing multi-material blended products is no longer difficult.
