    • 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.
    • 本发明涉及一种接触角大于或等于90度,强度为2.0g /旦的织物细丝。 这种长丝是防水的或耐化学品的,而由其制成的纱线很容易加工成织物。 在一个详细的实施方案中,长丝是防水的并且包括第一纵向延伸的组分,其包含至少一种选自尼龙,聚酯,聚丙烯或其它长丝形成聚合物的聚合物,以及第二纵向延伸组分,其包含卤化 聚合物。 在第二个详细的实施方案中,长丝是耐化学性的并且包括第一纵向延伸的组分,其包含至少一种纤维形成聚合物和包含烯烃共聚物的第二纵向延伸组分。 在两个实施例中,第二纵向延伸部件存在于第一纵向延伸部件的外部。 本发明还涉及由长丝制成的纱线以及由纱线制成的织物以及制造纱线和织物的方法。
