Cotton Nylon Blend Fabric Dyeing Process Step By Step

The cotton-nylon blend fabric dyeing process is a unique dyeing procedure. For knit fabric dyeing industry is an uncommon dyeing process. Cotton dyeing is an alkaline medium process. Nylon dyeing is an acidic medium dyeing process. On the other hand, cotton needs reactive dyes and nylon needs acid dyes. As a result, is a critical dyeing process.

So that it needs two-bath dyeing processes to make it a solid look. First, we have to dye the cotton part and then we have to dye the nylon part. We can also reverse it. Cotton dyeing at first is a good practice. Because reactive dyes have good fastness properties than acid dyes.

In the Cotton nylon blend fabric dyeing process, cotton parts need 60⁰c for dye fixup, and nylon needs 98⁰c-100⁰c temperature for bonding. So that at 98⁰c temperature reactive dye can be lighter a little bit. For this reason, we should keep the cotton shade 10% darker than the master shade.
