摘要： Apparatus and method are described for measuring and controlling the crimp characteristics of a moving crimped tow. A light source illuminates a section of the moving crimped tow and at least one progressive scanning camera acquires a non-interlaced video image of the tow. The acquired image is digitized and a processor analyzes the non-interlaced image. Crimp characteristics are derived based on this analysis.

摘要： Methods and devices are provided to actively apply finish to one or more yarns in motion at speeds greater than about 3000 m/min, to achieve a finish application of 0.2 wt. % or more, and with a coefficient of variation of finish concentration of 10% or less. The devices are compact, portable and readily installed at a variety of positions on a fiber processing line. The devices of the invention contain the finish so that contamination of the surrounding areas is prevented. The devices may be used to provide an overfinish to a moving yarn between heated godet rolls. The so-provided heating may be used to dry the yarn and to promote curing reactions in the finish and between the yarn and finish compounds. The invention also includes the finished yarn products so produced. A yarn with increased finish uniformity is provided with an overfinish actively applied and dried on the draw bench before the first winding operation. The yarn products of the invention may be used in textile and leisure fiber applications, and in industrial fiber applications, such as in tires.

摘要翻译： 提供了方法和装置，用于以大于约3000m / min的速度主动地对一根或多根运动中的纱线进行精加工，以实现0.2wt。 ％以上，成品浓度变化系数为10％以下。 这些设备是紧凑型，便携式的，并且易于安装在纤维加工生产线上的各种位置上。 本发明的装置包含整理剂，从而防止了周围区域的污染。该装置可用于向加热的导丝辊之间的移动纱线提供过涂层。 可以使用如此提供的加热来干燥纱线并促进整理剂和纱线与精制化合物之间的固化反应。本发明还包括如此生产的成品纱线产品。 具有提高精加工均匀度的纱线提供了在第一次卷绕操作之前在拉伸台上积极施加和干燥的过涂层。 本发明的纱线产品可用于纺织和休闲纤维应用以及工业纤维应用中，例如在轮胎中。
