Factors Affecting the Dyeing of Microfiber Leather

Consumers like the colorful colors of microfiber leather. Buyers care about the color fastness of microfiber leather. As a microfiber manufacturer, they continue to explore the dyeing technology of microfiber leather. In fact, the dyeing of microfiber is indeed a worldwide problem. Let's talk about several major factors that affect the dyeing of microfiber leather.

         First. The influence of superfine fiber: As the nylon fiber in superfine leather is very fine, the fineness is usually 0.0001 to 0.001 denier, the adsorption speed of dye is very fast, and such a fast speed will cause very poor uniformity. Dyeability; at the same time, if the fiber is thinner, the specific area is larger, resulting in poorer color rendering; in addition, the thinner the fiber, the dye in the fiber is easy to migrate to the fiber surface, which is also commonly referred to as color fastness In addition, too fine fibers will consume a lot of dyes, not only the dyeing cost is high, but also the washing fastness and rubbing fastness will be poor.

        Second.the influence of non-woven fabrics: Super-fiber leather has high requirements for non-woven fabrics. If the thickness of the non-woven fabric is uneven and the fiber distribution is uneven, the dyeing effect will be greatly affected.

　　Third. The influence of resin: Bundle-shaped superfine fibers are impregnated into polyurethane resin to form the primary product of superfiber leather. If the polyurethane resin is unevenly distributed, it will also affect the dyeing effect. At the same time, the coloring properties of different resins will also affect the dyeing effect.

　　Fourth. the influence of dyes, auxiliaries and dyeing technology: Dyes and auxiliaries are different due to different varieties and prices, plus different dyeing processes, all affect the dyeing effect of microfiber leather.
