One key issue for retailers and their suppliers is how to achieve deep colors on micro denier fabrics.
At natific, we frequently speak about feasibility. Achieving deep colors on micro denier is often a feasibility case.
A feasibility case is solved by modifying a color and, if needed, the dyeing recipe so that it’s possible for the dyer to achieve the requested color (or come as close to it as possible) on any chosen material.
Micro denier fabric
The construction of micro denier fabrics is different compared to traditional fabrics. It's made from synthetic yarns like polyester or nylon, where many filaments are processed together to form a yarn that will eventually be formed into a fabric. The size of the yarn is defined as the denier.
In order to be considered a microfiber the fiber must be less than 1 denier, which is extremely fine. This gives the fabric an airy weight, downy feel, and soft, silky texture. 
Why does this issue happen on micro denier fabrics?
Looking at the construction of a micro fiber fabric, micro filaments have an enormously higher surface area compared to normal denier. More filaments in yarn result in more surface area.
Because of the larger surface area, when an identical amount of dye is used for normal denier fabric and for micro denier fabric, micro denier fabrics show lighter depth of shade.

It creates a challenge for the dyers to achieve a deep and level shade with a high level of color fastness on microfilament fabrics.
It might sound necessary to introduce more dye in microfilament fabric to get a solid deep shade. However, at a certain point each dye is maxed out in exhaustion (not giving a deeper shade).
For polyester, you can go from a 3-dye combination to a 5-dye combination. This means that instead of applying more of each dye, which not will make your final color deeper, you can add another dye to increase the depth up to a certain point.
Solving one issue can lead to problems in other areas
When changing a recipe, there are other quality requirements such as fastness issues to consider and the dye cost might increase due to a larger amount of dye combination.
Properly selected dye type and dye combination, optimized dyeing conditions, and appropriate after-treatment need to be considered to achieve the color quality requirements.
Speed up your problem solving
To address the issues coming from microfibers, we have added a fiber fineness specification to natific’s Voodoo system. The predictions and feasibility assessments in Voodoo are adjusted to micro denier fabrics and other fabric specifications.
You can use natific’s system Voodoo to:
1. Check if your colors are feasible and possible to be achieved in production
2. Create an optimized reflectance curve to use as your feasible Digital Color Standard
3. Get a proposal for your best possible match
4. See technical details (metameric, fastness performance etc.)
