自由端纺纱

本文提到了Kamp纺纱和碟盘纺纱这二种新的自由端纺纱方法。

As two new methods of open-end spinning , Heinz Kamp ′ s spinning and Disc spinning are mentioned .

开端纺纱（断裂纺纱）和自由端纺纱的意义是相同的。

Break spinning and open-end spinning are synonymous .

目前采用的开端纺纱或叫自由端纺纱的方法有两种：气流纺纱和流体（或空气，或涡流）纺纱。

Two methods of open - end or break spinning are in use : rotor spinning and fluid or air or vortex systems .

相比于其他纺纱技术，喷气涡流纺成纱过程采用高速旋转的气流对纤维须条加捻成纱，属于完全自由端纺纱范畴。

Compared with other spinning process , the twisting process of air-jet vortex spinning belonged to free-end spinning technology is achieved by high-speed rotating airflow .

转杯纺纱属自由端纺纱方法，是目前各种新型纺纱技术中已经工业化推广的一种纺纱新技术。

As an open-end rotor spinning method , rotor spinning is a new spinning technology , which has gotten widespread industrial application among different new kinds of spinning technology .

转杯纺纱是利用高速旋转纺杯纺制纱线的一种自由端纺纱技术，也是目前各种新型纺纱技术中最为成熟、发展最快和应用：最广的一种纺纱方式。

Rotor spinning , one kind of open-end spinning by means of high speed rotor , is the fastest-developing and widely used means of spinning of all new spinning technologies .

事实上，根据目前纺纱工艺的状况，自由端纺纱生产的纱线，特别是气流纺纱线，可以在各种用途上与环锭纺纱线竞争。

In fact , with the current state of the art of spinning , open-end spun yarns , particularly rotor-spun , compete with ring-spun in nearly every possible end use .

在这一部分中则将利用上述基本方程和结论，分析一些典型理想加捻过程，包括加捻的过渡过程以及传统纺纱和自由端纺纱的稳态加捻问题。

In this part , the equations are applied to solve a series of typical twisting problems , including the transient and steady state solutions for conventional and open-end spinning systems .

随着使用转杯原理制成的商业化自由端纺纱机的发展，有关学者已经做了广泛的研究工作，旨在提高纱线质量和纺纱经济方面的有效性。

Since the advent of commercial open-end spinning machines using the rotor principle , there has been extensive research work on enhancing their effectiveness in terms of both yarn quality and spinning economics .

本文通过传统纺纱和自由端纺纱纱线结构的对比试验和研究，重点分析了摩擦纺纱纱线的内部捻度分布，各层截面中纤维密度分布以及伸直度和定向性等特点。

Through an investigation and contrastive test of conventional and OE yarns this paper mainly analyses friction spun yarn inner twist distribution , fibre density distribution in each yarn cross-section layer and fibre straightness and orientation .

Finally , a kind of spinning device of open-end air-jet is designed on the basis of experimented exploration .

本论文在内容上，主要包括五部分：第一部分对喷气纺纱的发展和研究现状、自由端喷气纺纱的发展和研究现状及选题的目的意义、研究内容做了简要概述；

In the first part , the development of air-jet spinning , the research actuality , the aim of this thesis and the research content are introduced .

自由端喷气纺纱是以高速气流辅以罗拉牵伸而形成自由端，并利用高速旋转气流对须条进行加捻的一种新型纺纱方法。

Open-end jet spinning is a new spinning method , which works in such a way that a high-speed air current forms the open end with the aid of roller drafting , while a high-speed rotating air current inserts twist to the sliver .
