    • A process for imparting flame resistance and the flame resistant fabrics produced by such process are provided. The process for imparting flame resistant properties involves treating a target fabric with one or more flame retardant chemicals (and, preferably, a softening agent) and then curing the treated fabric to durably affix the flame retardant to the fabric. In many cases, it may be desirable to subject the treated fabric to mechanical face finishing to increase softness. Optionally, stain release agents, soil repellent agents, permanent press resins, and the like may be added to the bath of flame retardant chemicals, eliminating the need for one or more additional manufacturing processes. Alternately, soil repellent agents may be applied to only one side of the treated fabric after the application of the flame retardant chemicals. The present fabrics exhibit improved performance and tear strength, even after repeated launderings, as compared to conventionally treated fabrics.
    • 提供了赋予阻燃性的方法和通过这种方法制造的阻燃织物。 赋予阻燃性的方法包括用一种或多种阻燃化学品(和优选软化剂)处理目标织物,然后固化经处理的织物以将阻燃剂持久地粘贴到织物上。 在许多情况下,可能需要使经处理的织物进行机械表面处理以增加柔软度。 任选地,可以在阻燃化学品的浴中加入脱色剂,防污剂,永久性压制树脂等,而不需要一个或多个附加的制造工艺。 或者,在施用阻燃化学品之后,可以仅在处理过的织物的一侧施用防污剂。 与常规处理的织物相比,本发明的织物甚至在重复洗涤之后表现出改进的性能和撕裂强度。

    • A sponge-like polymeric adsorption material prepare by a process including: preparing a linear polymer yarn from a linear polymer via melt-blow spinning, treating the linear polymer yarn with a crosslinking agent and a porogen agent; heating the treated linear polymer yarn at 130 to 150° C. for 25 to 35 seconds to obtain a fibrous polymeric adsorption material; and weaving the fibrous polymeric adsorption material to obtain the sponge-like polymeric adsorption material. The linear polymer has a molecular weight of 15,000 to 20,000 g/mol. The fibrous polymeric adsorption material includes fibers with a diameter of 4 to 6 microns. The crosslinking agent is in an amount of 1 to 3 weight % of the linear polymer. The crosslinking agent is a diacrylate ester compound having Formula J1, J2 or J3. The porogen agent is in an amount of about 1 weight % of the linear polymer. The sponge-like polymeric adsorption material has a thickness of 15-20 mm and a density of 600-720 g/L. The linear polymer has a molecular weight of 15,000 to 20,000 g/mol.
