Description

一种可减少纱线毛羽的纺纱装置
技术领域
本发明涉及一种安装在环锭细纱机上， 可改善纱线毛羽性能的纺纱装置，属 纺织加工技术领域。
技术背景
毛羽是衡量纱线质量的重要指标之一。纱线毛羽不仅影响机织、针织等后工序的 生产效率,而且影响最终产品的外观质量,特别是无梭织机普遍应用的今天,减少纱线 毛羽具有十分重要的意义。
国内外在减少纱线毛羽方面通常采用的方法有两种，一种是采用常规方法， 另一 种是采用专用的毛羽减少装置来消除毛羽。常规方法是通过工艺参数的合理优化或应 用一些新型纺纱技术来降低毛羽的产生， 如提高纱线捻度、 降低纺纱速度、适当增加 纺纱张力、适当降低细纱后区牵伸倍数或采用如紧密纺技术等。通过在传统的环锭纺 纱机上添加一些简单的毛羽消除装置来减少纱线毛羽是目前纺纱技术研究的热点。
目前研究的在环锭纺纱机上添加毛羽消除装置来减少纱线毛羽方法基本有两种： 一是采用气流喷射的方法。即在前罗拉和导纱钩间安装气流喷射装置，利用气流的回 转使已形成的毛羽贴伏在纱线表面，如美国专利商标局 1979年 4月 10日公开的发明 专利 "纱线处理的方法和装置 ( method and apparatus yarn treatment ) ", 专利号 41481779、美国专利商标局 1989年 8月 22日公开的发明专利 "改善短纤纱性能的方 法禾口装置 ( method and apparatus for modifying spun textile yarn ) "， 专禾1 J号 5263311。 这些研究主要差别在于由于气流喷射装置的不同导致纱线表面纤维受力方向不同，从 而产生不同的卷绕效果而导致纱线毛羽消除效果的不同。但是由于这些装置只能安装 在加捻三角区后（因加捻三角区中的纤维基本成散纤维装， 喷射的气流会导致纤维运 动混乱而断头）， 即其处理对象是已经形成的毛羽， 只是使这些毛羽贴伏在纱线表面， 还是呈一种松弛不受力状态， 在后道工序（如络筒）加工中， 纱线与机件的摩擦又会 使这些贴伏的毛羽重新显露出来，达不到消除毛羽的目的。另一种方法是在纺纱过程 中对纤维进行热湿处理，降低纤维的刚度，提高纤维在成纱过程中向内部转移的能力， 从而降低毛羽生成。 如中国发明专利 "一种改善纤维成纱性能的方法及装置"、 公开 号 CN1556268A, "—种改善纱线性能的熨烫纺纱方法" 、 公开号 CN1995510A, 美 国专利 "在环锭纺纱机上生产高性能纱线的方法和装置 （Method of and Apparatus for producing high quality yarn on a ring-spinning machine) "、公开号 US 20080155786A1。 这些发明是在纺纱过程中对纤维进行热、湿处理， 降低纤维刚度、提高纤维向内转移 能力， 从而可有效减少纱线毛羽的产生， 但由于所用装置的加工和安装精度较高， 使 得加工、 使用成本较大， 且影响挡车工的操作。
发明内容
针对上述存在的问题，本发明的目的在于提供一种对所纺纱线中的纤维，特别是 对加捻三角区中的纤维进行处理， 可改善纱线性能，特别是可减少纱线毛羽的纺纱装 置。
本发明的技术解决方案为： 由带有安装口的纱线处理部件、加热组件和绝热材料 组成， 其中， 纱线处理部件的内部为与安装口相通的空腔， 空腔内设置有加热组件， 纱线处理部件上的安装口还设有起封闭作用的封盖。加热组件由两片与外接电源相连 的电极片、加热片和隔离保护层组成， 加热片位于两片电极片之间， 隔离保护层由导 热、 绝缘、 耐高温材料制成， 隔离保护层可以呈片状也可以呈包覆状。 当隔离保护层 呈片状时，其中一片电极片的外表面与纱线处理部件空腔的内壁面紧密接触， 另一片 电极片的外表面外侧设置有隔离保护层， 隔离保护层外侧填充有绝热材料。当隔离保 护层呈包覆状时， 隔离保护层包覆在两片电极片和加热片的外侧， 且其内表面与两片 电极片的外表面紧密接触，隔离保护层中与其中一片电极片相接触的侧面的外表面与 纱线处理部件空腔的内壁面紧密接触，与另一片电极片相接触的侧面的外侧填充有绝 热材料。 纱线处理部件的外部形状为长方形、 圆柱形、 中间有凹槽的长方形。 当纱线 处理部件的外部形状为长方形时，纱线处理部件沿长度方向的两个侧面与上平面之间 为圆弧状； 当纱线处理部件的外部形状为中间有凹槽的长方形时， 纱线处理部件的凹 槽沿长方形长度方向贯通， 凹槽的深度不超过长方形厚度的一半， 凹槽的壁面与长方 形各个侧面之间为圆弧状。
由于采用上述技术方案，本发明安装在环锭细纱机前钳口前端，对从前钳口输出 的纤维须条进行处理， 可有效地减少纱线毛羽的产生， 达到减少纱线毛羽的目的， 且 装置结构合理， 加工、 组配方便， 安装、 操作简单。
