A major key to successful pretreatment, dyeing, and finishing is thorough wetting of the goods to be processed. There must be no “rising to the top,” and a package or beam must have consistent and unimpeded flow to provide effective interaction between dye liquor and substrate. The trouble is there are real physical impediments to flow. Examples of impediments are variations in the actual physical substrate, variations in how the physical substrate is presented to the liquid bath, and entrapped air pockets either in the yarn or in the fabric. When the goal is to penetrate goods to be processed in a paddle machine, pockets of air must be removed from densely packed bags of garments or fabric. When trying to move a dyebath through a beam or package, trapped air must be removed to make liquor-flow unimpeded, efficient and effective. A trapped pocket of air can leave light or undyed areas that will cause time-consuming rework and lost productivity. Penetrants, such as Penetrant BDP, are designed to remove the impediments to flow and provide even, uniform movement of liquid through fiber or fabric. This results in: Air pockets dissipating Wetting/penetration of difficult fibers and fabrics Sinking of goods in paddle machines and wenches The result: a level, uniform dyeing or finish application. Beyond its invaluable function to eliminate trapped air, Penetrant BDP provides durable anti-foaming properties throughout the wet processing cycle. Suitable for all fiber types and fabric constructions, Penetrant BDP is tolerant to high electrolyte levels, alkali, peroxide and mechanical sheer. Be sure to check out the below video to see Penetrant BDP (left in the video) in action as it works its magic on a nylon/spandex blend, and contact us today to get started.
