    • Fire retardant and heat resistant yarns and fabrics include an inner core comprised of oxidized polyacrylonitrile encapsulated by an outer shell comprised of a liquid-resistant and strengthening polymer material. The liquid-resistant and strengthening polymer material includes one or more types of cured silicone polymer resin. A fluorchemical may be at least partially impregnated into the inner core prior to applying the liquid-resistant and strengthening polymer material in order to further enhance the liquid shedding properties of the yarns or fabric. Because the silicone polymer resin only encapsulates the yarn, but does not form a continuous coating over the whole fabric, the treated fabric is still able to breath through pores and spaces between individual yarn strands that make up the fabric. The liquid-resistant and strengthening polymer material increases the strength, abrasion resistance, durability and liquid and gel shedding capability of the fire retardant heat resistant yarn or fabric.
    • 阻燃和耐热的纱线和织物包括由氧化聚丙烯腈构成的内芯,所述氧化聚丙烯腈由包含耐液体和强化聚合物材料的外壳封装。 耐液聚和强化聚合物材料包括一种或多种固化的聚硅氧烷树脂。 在施加耐液体和强化聚合物材料之前,氟化物可以至少部分地浸渍到内芯中,以进一步增强纱线或织物的液体脱落性能。 由于硅氧烷聚合物树脂仅包封纱线,而是在整个织物上不形成连续的涂层,所以经处理的织物仍然能够通过构成织物的各个纱线之间的孔和间隙呼吸。 耐液体和强化聚合物材料增强了阻燃耐热纱线或织物的强度,耐磨性,耐久性和液体和凝胶脱落能力。
