Chemical Bonded Non-Woven

For more than four decades, almost all Non-Woven required a chemical binder in order to provide any measure of structural integrity. In addition, the binder was called upon to contribute and convey numerous properties that were necessary for the effective performance of the fabric.

Since inception Feathtouch is making chemically bonded Non-Woven. Generally binders are the weak element in developing fully acceptable Non-Woven fabrics. The fibers that were available to the Non-Woven industry were the same fibers that were available to the textile and other fiber-based industries; hence, the fibers were fully acceptable. It was generally the binder that limited the performance of the Non-Woven fabric. And there deficiencies attributable to an inadequate binder. Common complaints are as follows:

As a consequence, a great deal of effort has been put into the development and continuous improvement of chemical binders. The steady improvements in Non-Woven performance that occurred over a period of many years were in no small measure due to improvements in the performance and utility of the binder. Polyvinyl acetate was the main binder used when we started producing Non-Woven in 1988. This material had distinctly superior adhesive properties, strength, and performance compared to the early natural adhesives. This binder had considerable flexibility in formulation, and could easily be applied to fiber webs by a variety of application processes.

At Feathtouch we are very cautions about the environmentally friendly Non-Woven. Our binders are totally formaldehyde-free, low-cure temperature binders, complex copolymers with unique characteristics, moldable binders, and others. We can also produce Non-Woven where Non-Woven require or face stringent flame-retardants regulations; with binder system often we introduce agents that can convey flame retardancy. Because they can accept pigments and dyes, binders can often help in adding color to Non-Woven fabrics.
