An anti-microbial and / or anti-fungal synthetic fiber that comprises various thermoplastic polymers and additives in a bi-component form in either a core-sheath or side-by-side configurations. The anti-microbial synthetic fibers comprise inorganic anti-microbial additives, distributed in certain areas to reduce the amount of the anti-microbial agents being used, and therefore the cost of such fibers. The fibers can incorporate anti-microbial additives so that they are not removed by repeating washing in boiling water and in dry clean cycles and become ineffective and conversely enhance access to the additives by washing or the like. The fibers comprise high tenacity polymers (e.g. PET) in one portion and hydrolysis resistance polymers (e.g. PCT) in another portion with the additives. The fibers can further be blended with non-anti-microbial fibers such as cotton, wool, polyester, acrylic, nylon etc. to provide anti-microbial finished fabrics. In one such embodiment, binder fibers are used which are mixed with other fibers.

The present invention provides improved cooling of a veil of glass fibers by using a combination of nozzle assemblies. The nozzle assemblies include air caps of differing configurations to control the penetration of the spray into the veil. One suitable spray configuration is a nozzle assembly having punch air cap that creates a narrow exit angle, high velocity flow of droplets to penetrate the veil to cool the fibers at the interior. Another suitable configuration is a nozzle assembly having a flat air cap that creates a wide exit angle, low velocity, dispersed spray pattern to cool the exterior of the veil. Preferably, the flat air cap creates a very fine particle size to increase the cooling efficiency of the spray. By using the cooling ring of the present invention, lower levels of binder to be applied to the fibers and environmental emissions from the plant may be reduced.
