    摘要： A sizing composition for reinforcement fibers that includes one or more film forming agents, a silane coupling agent package, and at least one lubricant surfactant is provided. Optional components such as rheology modifiers, fillers, biocides, and pH modifiers may also be included. Preferred film forming polymers are amide-based polymers. Additionally, the sizing composition is free of polyvinyl alcohol. The absence of polyvinyl alcohol in the size composition reduces or eliminates the production of precipitates from white water in wet-laid processes. The size composition is applied to reinforcement fibers and formed into chopped strand, wet-laid mats that can be used for a variety of purposes, including roofing products. Chopped strand mats formed from fibers sized with the inventive sizing composition maintains or improves the dry tear and tensile strengths compared to chopped strand mats made from fibers sized with a commercial sizing composition that does not contain polyvinyl alcohol.

    摘要翻译： 提供了包括一种或多种成膜剂，硅烷偶联剂包装和至少一种润滑剂表面活性剂的增强纤维用施胶组合物。 还可以包括任选的组分如流变改性剂，填料，杀生物剂和pH调节剂。 优选的成膜聚合物是基于酰胺的聚合物。 另外，上浆组合物不含聚乙烯醇。 尺寸组合物中不存在聚乙烯醇降低或消除了在湿法成网工艺中从白水生成沉淀物。 尺寸组合物用于增强纤维并形成短切纤维，可用于各种目的的湿敷垫，包括屋顶产品。 由使用本发明的施胶组合物尺寸的纤维形成的切断的丝网垫与由不含聚乙烯醇的商业施胶组合物尺寸的纤维制成的短切丝网垫相比，保持或改善了干撕裂和拉伸强度。

    摘要： A laminated shingle resistant to fastener-head pull-through. The shingle includes an upper layer having a tab portion and a headlap portion, and a shim extending below the tab portion and part of the headlap portion. The part of the shim behind the tab portion forms, with the headlap portion, a dual thickness nailing zone. Since roofers sometimes drive fasteners such as roofing nails through the shingle behind the nailing zone, resulting in only a single layer available to resist fastener-head pull-through, a reinforcing tape which can have reinforcing strands is adhered to the bottom of the headlap portion immediately behind the rear edge of the shim. This effectively increases the size of the nailing zone without incurring the bulk, weight and cost of increasing the size of the shim.
