The present invention relates to a textile filament with a contact angle greater than or equal to 90 degrees. Such filaments are either water-repellent or resistant to chemicals, and yarns made therefrom readily processible into fabrics. In a detailed embodiment, the filaments are water-repellent and comprise a first longitudinally-extending component comprising at least one polymer selected from nylon, polyester, polypropylene, or other filament-forming polymer, and a second longitudinally-extending component, comprising a halogenated polymer. In a second detailed embodiment, the filaments are chemical-resistant and comprise a first longitudinally-extending component comprising at least one fiber-forming polymer and a second longitudinally-extending component comprising an olefin copolymer. In both embodiments, the second longitudinally-extending component is present on the exterior of the first longitudinally-extending component. The present invention also relates to yarns made from the filaments, and fabrics made from the yarns, as well as methods of making the yarns and the fabric.

Process of making low surface energy fibers

The present invention relates to a textile filament with a contact angle greater than or equal to 90 degrees and a tenacity of 2.0 g/den. Such filaments are either water-repellent or resistant to chemicals, and yarns made therefrom readily processible into fabrics. In a detailed embodiment, the filaments are water-repellent and comprise a first longitudinally-extending component comprising at least one polymer selected from nylon, polyester, polypropylene, or other filament-forming polymer, and a second longitudinally-extending component, comprising a halogenated polymer. In a second detailed embodiment, the filaments are chemical-resistant and comprise a first longitudinally-extending component comprising at least one fiber-forming polymer and a second longitudinally-extending component comprising an olefin copolymer. In both embodiments, the second longitudinally-extending component is present on the exterior of the first longitudinally-extending component. The present invention also relates to yarns made from the filaments, and fabrics made from the yarns, as well as methods of making the yarns and the fabric.
