Do you know what is “super indigo” denim?
As a result of super indigo dyeing or extra-deep indigo dyed denim garments after grinding and washing. It can obtain special effects with strong and bright color, and is widely welcomed by consumers.
“Super Indigo” dyed denim has two major characteristics: that is, the dyeing depth is very deep and the color fastness to washing is very good. The former means that the amount of indigo dye dyed on the yarn per unit weight is particularly large. For example, the indigo dyeing depth of conventional denim warp yarns is 1% to 3%. The “Super Indigo” dyeing depth needs to reach more than 4%. It can be called super indigo or extra deep indigo. The latter refers to the “super indigo” dyed denim that needs to withstand repeated grinding and washing for more than 3 hours. Its color can still reach or exceed the color depth of conventional dyed denim without scrubbing. And its shade is much brighter and brighter than conventional dyed denim.
The so-called “fast indigo dyeing process” in the past. In fact, in the yarn dyeing process, the degree of penetration of the indigo dye to the fiber is deliberately low. In this way, when denim clothing is rubbed and washed, the very thin layer of dye on the surface of the yarn is rubbed off, exposing more white yarn cores. Make the color fade quickly, so as to achieve the effect of fading immediately after a short time of scrubbing. The “Super Indigo” dyeing process is the opposite, requiring a particularly good degree of dye penetration. In order to make denim garments have a deep and bright color after being washed and processed.
