Description

单纱、 单纱制品及其制备方法
技术领域
本发明涉及高分子材料技术领域，特别是涉及一种单纱、单纱制品及 其制备方法。
背景技术
超高分子量聚乙烯（Ultra High Molecular Weight Polyethylene, 简 称 UHMW-PE )是一种线型结构的具有优异综合性能的热塑性工程塑料， 以这种材料为基础制成高强纤维是其重要用途之一。
超高分子量聚乙烯纤维是一种高性能纤维， 具有强度高、 耐磨、 耐冲 击、 耐腐蚀、 耐紫外等优点， 可广泛应用于多个领域， 例如： 超高分子量 聚乙烯纤维可用于制备绳索、 吊具、 渔网和各类织物等民用领域， 可应用 于制备防弹背心、 防弹头盔等个体防护产品领域， 还可应用于防弹地板、 装甲防护板等国防军需领域。
由于超高分子量聚乙烯纤维为丝状结构 （单丝纤度 2.5旦左右）， 因此 在基于超高分子量聚乙烯纤维制备各类产品的过程中， 需要对多根丝状结 构的纤维进行分别整理， 工艺复杂， 成本高， 且在产品制备过程中， 纤维 表面受摩擦易产生毛刺， 纤维易发生断丝、 扭曲、 缠绕等现象， 不利于多 根纤维的整体均匀受力， 导致制得的产品的整体强度往往低于多根超高分 子量聚乙烯纤维的强度， 强度利用率较低。

超高分子量聚乙烯是分子量 100 万上的聚乙烯。 超高分子量聚乙烯 应用的传统技术是以超高分子聚乙烯纤维为基础制备各类产品。本发明各 实施例提供的技术方案，与超高分子量聚乙烯应用的传统技术有着本质的 不同，是对传统技术提出的革命性创新， 即将超高分子量聚乙烯薄膜或条 带替代传统的超高分子量纤维进行应用产品的开发和制备，其核心思想主 要包括：
(一）将超高分子量聚乙烯薄膜或条带，替代传统的超高分子量聚乙 烯纤维， 来制备单纱， 即： 将超高分子量聚乙烯薄膜或条带收束或收束加 捻制得单紗。
(二）将由超高分子量聚乙烯薄膜或条带收束或收束加捻而成的单 紗， 替代传统的超高分子量纤维， 来制备各类产品（以下称为单紗制品）。
其中， 如图 la所示， 超高分子量聚乙烯薄膜 101是一种由超高分子 量聚乙烯制成的、 具有一定宽度和厚度的薄片， 且宽度远远大于厚度。 如 图 lb所示， 超高分子量聚乙烯条带 102可独立制备或可由该薄膜拉伸前 后进行分切工序形成的条状薄片，条带的宽度小于薄膜的宽度，厚度与薄 膜相当或大于薄膜的厚度。
本发明提供的超高分子量聚乙烯薄膜或条带，与超高分子量聚乙烯纤 维不同， 与由多根超高分子量聚乙烯纤维胶接形成的平面也不同， 它们的 显著区别在于：本发明提供的超高分子量聚乙烯薄膜或条带本身具有一定 的宽度和厚度， 是一种没有结合点或裁切线的整体结构。
本发明各实施例提供的单纱基于超高分子量聚乙烯薄膜或条带制得。 在所述单纱制备过程中，是将超高分子量聚乙烯薄膜或条带作为一个整体 进行处理， 结构整体性好、 制备工艺简单， 省去了对多根纤维丝进行分别 整理的复杂工艺， 明显降低了薄膜或条带的表面产生毛刺的概率，也明显 降低薄膜或条带内部出现断丝、扭曲、缠绕等现象的概率。 将超高分子量 聚乙烯薄膜或条带收束而成的单纱承载荷载时，超高分子量聚乙烯薄膜或 条带是整体受力， 使得采用超高分子量聚乙烯薄膜或条带的单纱的强度， 高于采用相同旦数的超高分子量聚乙烯纤维制备的产品，具有结构整体性 好、 强度高、 强度利用率高、 生产效率高、 加工成本低、 重量轻、 线密度 小、 柔性好等优点。
本发明各实施例提供的单纱完全可替代传统的超高分子量聚乙烯纤 维制备产品在各个领域得到广泛的应用。具体而言，本发明各实施例可将 所述单纱替代超高分子量聚乙烯纤维制备各类单纱制品。在单紗制品的制 备过程中，是以单纱为基础进行加工处理，相对传统以超高分子量聚乙烯 纤维为基础进行加工处理得到的同类产品而言， 单纱制品结构整体性好、 制备工艺简单、 生产效率高。 单纱制品承载荷载时， 各单纱是整体受力， 使得采用所述单纱制备的单紗制品的强度，高于采用相同旦数的基于超高 分子量聚乙烯纤维制备的同类产品，有效提高强度利用率， 同时还具有结 构整体性好、 重量轻、 线密度小、 环保等优点。
单纱及其制备方法实施例
本发明实施例提供的单纱 201 由超高分子量聚乙烯薄膜或条带收束 而成， 如图 2所示， 可将超高分子量聚乙烯薄膜或条带收束制得单纱。 一 个可选的工艺过程例如：将超高分子量聚乙烯薄膜或条带放置在筒子架上 放出， 依次经导丝机构、 束丝机构后卷绕到管芯上。 制得的单紗具有结构 整体性好、 强度高、 强度利用率高、 生产效率高、 加工成本低、 重量轻、 柔性好等优点。此外， 由于所述单纱是由超高分子量聚乙烯薄膜或条带收 束而成， 故相对传统基于超高分子量聚乙烯纤维胶接而成的同类产品而 言， 所述单纱还具有无胶、 环保等优点。
可选的，单纱还可由超高分子量聚乙烯薄膜或条带收束加捻而成， 即 将超高分子量聚乙烯薄膜或条带先收束再加捻制得单纱。加捻的捻向和捻 度可根据实际需要确定， 本发明各实施例对比并不限制， 例如： 对收束后 的超高分子量聚乙烯薄膜或条带加捻的捻向可为左捻或右捻， 捻度为 1-100个 /m。 该方案制得的单纱还具有紧实度好， 不易松散等优点， 便于 加工单纱制品， 降低加工成本， 提高生产效率。 可选的，在单纱的制备过程中，所述超高分子量聚乙烯薄膜或条带可 沿其分子链伸直方向收束。 由于超高分子量聚乙烯具有线性结构，超高分 子量聚乙烯薄膜或条带沿其分子链伸直方向的强度最大，故沿其分子链伸 直方向收束制备单紗， 即可提高单紗的强度，还可降低对因收束处理对薄 膜或条带的强度性能可能造成的损失， 强度利用率高。
可选的，所述超高分子量聚乙烯薄膜的相关参数至少满足以下一种或 多种： 线密度在 5000旦以上； 宽度 100mm以上； 厚度 0.2mm以下； 断裂 强度在 10克 /旦以上；拉伸模量在 800克 /旦以上；断裂伸长率在 6%以下。 基于具有上述一种或多种特性的超高分子量聚乙烯薄膜制备单纱，使得单 紗整体强度更高， 可更好满足高强度荷载、 防弹等产品的制备需求。
可选的，所述超高分子量聚乙烯薄膜的相关参数至少满足以下一种或 多种： 线密度在 100旦以上； 宽度 l-100mm; 厚度 0.2mm以下； 断裂强 度在 10克 /旦以上； 拉伸模量在 800克 /旦以上； 断裂伸长率在 6%以下。 基于具有上述一种或多种特性的超高分子量聚乙烯条带制备单纱，使得单 纱整体强度更高， 可更好满足高强度荷载、 防弹等产品的制备需求。
本实施例各方案提供的由超高分子量聚乙烯薄膜或条带收束或收束 加捻而成的单纱， 除了具有耐磨、 耐冲击、 耐腐蚀、 耐紫外等超高分子量 聚乙烯纤维类似的优点之外， 还具有结构整体性好、 强度高、 强度利用率 高、 生产效率高、 加工成本低、 重量轻、 线密度小等独特优势， 因此所述 单紗可替代传统的超高分子量聚乙烯纤维制备各类产品， 广泛应用于民 用、 个体防护、 国防军需、 土木工程、 工业建筑、 海上作业、 渔业捕捞、 船舶制造、 体育用品等各个领域。

例 3: 可将多根单纱单向排列连接为一体， 制得具有单层结构的单紗 制品。
例如： 可将多根单纱沿单紗长度方向平行排列， 并通过绑定连接、胶 接或者热压连接等非交织的方式连接为一体， 制备单向布 801 (如图 8 )。 该方案制备的单向布可用于但不限于制备如增强结构件、 高强箱包、防弹 板、 耐冲击板、 防弹头盔、 防弹防暴箱包等产品， 可更好满足这些产品对 织物强度、 重量、 防弹等性能的特殊要求。
例 4: 可将多个经多根所述单纱单向排列连接而得的单层结构， 呈一 定角度交叉复合层压为一体， 制得具有多层结构的单纱制品。 其中：任意相邻的两个单层结构的交叉角度可以相同， 交叉角度可为

或者，各个单层结构中至少两个单层结构的交叉角度与其他单层结构 的交叉角度不同。如自首个单层结构到末个单层结构中各相邻两个单层结 构的交叉角度逐渐增加， 如此将不同交叉角度的单层结构（单向布 801 ) 层叠为一体， 制成具有多层结构的单纱制品 1001 (如图 10 )， 基于该单纱 制品可进一步制备其他产品形态的单紗制品，例如增强结构件、高强箱包、 防弹板、 耐冲击板、 防弹头盔、 防弹防暴箱包等产品， 可更好满足这些产 品对强度、 重量、 防弹等性能的特殊要求。
