PFAS Restrictions Rewriting Water Repellent Specifications Mid Season
Mid-season PFAS spec changes require re-engineering fabric density, adjusting curing parameters, and holding lot-traceable total fluorine CIC test evidence.
Hyperbranched Polymers
Synthetic Compound
Macromolecules with a highly branched and three dimensional structure offer unique properties compared to linear plastics used in textile finishing. The use of hyperbranched polymers allows for the creation of high performance surfaces without making the fabric stiff or uncomfortable for the wearer. These molecules have many terminal functional groups that can react with dyes or other chemical agents to provide new abilities to the cloth.
Molecular Architecture
The tree like shape of the molecule provides a large surface area for interactions at the microscopic level during the finishing process. When applying hyperbranched polymers, the finish can carry more active ingredients such as antimicrobial agents or flame retardants than a traditional linear coating. This structure also helps the polymer to penetrate the spaces between fibers more effectively which leads to a more durable result that survives laundering.
Textile Finishing
Improvements in dye uptake and crease resistance result from the application of these specialized resins to the cloth in a pad mangle. Because hyperbranched polymers have low viscosity despite their high molecular weight, they are easy to apply in standard industrial processes without clogging the equipment. They help in creating fabrics that stay soft while gaining new functional abilities like water repellency or soil release.
Surface Modification
Advanced chemistry allows for the engineering of textiles that repel water while remaining breathable for the wearer.
