Cationic polyester is that has been chemically modified to possess a permanent cationic, or positive, charge. Although the concept of cationic treated has been available for many years, this innovative technology has continued to grow in popularity among companies exploring ways to reduce water, energy and chemical consumption in the development of their products.

When immersed in water, polyester possesses a neutral or mildly negative charge.. Like common poles of magnets, same charges repel each other. Cationic treated polyester is chemically modified to possess a permanent cationic, or positive charge, making it easier to dye and increasing dye utilization.

This in turn creates a shorter and more efficient dyeing process that utilizes less water, energy and chemicals. Polyester can be treated with the cationic process in fiber, yarn, or fabric form.

Cationic yarns reflects solar glare and heat for cooler temperatures in the summer while the insulating construction reduces drafts, air conditioning and heating bills.
