    • The present invention provides a liquid repellent nonwoven protective material comprising a meltspun microfiber layer and one or more additional nonwoven layers bonded to the meltspun microfiber layer. The meltspun microfiber layer comprises a high melt flow rate olefin polymer (i.e., having a melt flow rate of at least 1500 grams per 10 minutes as measured by ASTM-D-1238-01 at 177 °C), a melt flow modifying agent and a liquid repellency internal additive. The high melt flow rate olefin polymer is substantially prodegradant-free and is present in amounts from about 78 percent by weight to about 94.9 percent by weight. The liquid repellency internal additive, such as a fluorochemical or fluoropolymer, is present in amounts from about 0.1 percent by weight to about 2 percent by weight, and the melt flow modifying agent, such as polymers and copolymers of butene, is present in amounts from about 5 percent by weight to about 20 percent by weight. The invention provides protective fabrics and garments such as medical products such as surgical drapes and gowns, and protective workwear garments from the liquid repellent nonwoven protective material. The invention additionally provides a process for making the nonwoven protective material.
    • 本发明提供了一种疏液非织造保护材料,其包括熔融超细纤维层和一个或多个附着的非织造层,其结合到熔融超细纤维层。 熔融超细纤维层包括高熔体流动速率的烯烃聚合物(即,在177℃下通过ASTM-D-1238-01测量的熔体流动速率至少为1500克/ 10分钟),熔体流动改性剂和 防液体内添加剂。 高熔体流动速率的烯烃聚合物基本上是无降解剂的,并且以约78重量%至约94.9重量%的量存在。 防液性内部添加剂,例如含氟化合物或含氟聚合物,以约0.1重量%至约2重量%的量存在,并且熔体流动改性剂,例如丁烯的聚合物和共聚物,以 约5重量%至约20重量%。 本发明提供保护性织物和衣服,例如医用产品如手术用纱和长袍,以及来自防液性非织造保护材料的防护性工作服装。 本发明另外提供了制造非织造保护材料的方法。
