A Guide to Spin-Dyeing Technology

Reduce water and energy use with spin-dyeing technology

As the textile industry strives to increase the sustainability of fibers and fabrics, we invite you to consider the advantages of dyeing man-made fibers with the spin-dyeing process. Our guide will provide an overview of what spin-dyeing is, its applicability, advantages, and drawbacks and how it compares to the more traditional wet or bath-dyeing technology.

We are a long-time provider of colorants and functional additives for spun-dyed fibers. Our products are polymer pellets – or in some cases liquid polymer – known as “masterbatch” or “concentrate”, that include the colorant and/or performance-enhancing additive at a concentrated level. Contact us to know more.

Putting a new spin on sustainable fashion

Fiber Solid Colorants


Avient offers a wide range of colorants for the spin-dyeing of polypropylene, polyester, polyamide and other man-made fibers like PLA and PHT. The masterbatches offer good spinnability and color resistance (fastness) to washing, heat, rubbing and light. A library of standard colors is available for defined applications e.g., carpets and nonwovens. Custom colorant solutions are rapidly developed in our fiber-dedicated color matching labs around the world.

Renol™ Fiber Colorants for PET, PA and other non-olefins

Fiber Additive Solutions


Additives can be used to enhance the properties and processability of fibers when required by the application and/or regulation. Our additive portfolio includes solutions to impart the following properties to fibers and filaments: UV/light stability, flame retardancy, antimicrobial efficacy, hydrophobicity and hydrophilicity, soft-touch effect, static electricity prevention, improved processability for recycled fibers, and more. These additives can be combined with color in a combination masterbatch for convenience.

Fiber Liquid Solutions


Liquid masterbatches can also be used to dye man-made fibers during the spinning process. They are injected later in the process compared to solid pellet masterbatches, which provide the benefit of more efficient color changeovers. Our experts can provide assistance in choosing between pellets and liquid masterbatches.
