What is color spinning?

Color spinning fiber, also known as colored fiber, is a fiber dyed before spinning. In the production of chemical fibers, appropriate colorants are added during polymerization or spinning. After spinning, the colorant is evenly dispersed in the fiber, which is called pre-spinning dyeing or stock solution coloring, and its fiber is color-spun fiber.

After spinning, the colorant is evenly dispersed in the fiber, which is called pre-spinning dyeing or stock solution coloring, and its fiber is color-spun fiber. This process is a physical change, and its advantages are continuous coloring and spinning, uniform coloring, good color fastness, high dye uptake, short production cycle, low cost and less pollution. It can also color some highly oriented, nonpolar and difficult-to-handle fibers such as polyester and polypropylene. Colorants include inorganic and organic pigments, carbon black and disperse dyes. Binders can also be made into color master batches for use.

Extended data color spinning can achieve the hazy three-dimensional effect and texture that white blank dyeing can not achieve. The use of color spinning is pollution-free, and the color difference is controlled to the greatest extent.

As the new process of "dyeing before spinning" is adopted in color spinning, the production process of post-processing enterprises is shortened, the production cost is reduced, and it has high added value. Compared with the traditional process of "spinning before dyeing", the performance of color-spun products is superior to other textile products, which has strong market competitiveness and good market prospects.

Features:

1, color spinning shows many colors on the same yarn, rich in color, full and soft. The fabric woven by color has a hazy three-dimensional effect, and the color is delicate, natural and layered.

2. Compared with the traditional process, the pre-spinning dyeing production process of colored spinning saves water and reduces emissions by more than 50%, which meets the requirements of low carbon and environmental protection. To produce an ordinary garment, color spinning can save 4 kilograms of water. If all the textiles in China were colored in the past year, 50 million tons of water would be saved.

3. The dyeing process of color spinning is unique, which has high scientific and technological content in fiber dyeing, color matching and multi-fiber blending. The birth of more new fabrics has promoted the growth of geometric products of clothing and home textile products.
