THE RIETER MANUAL OF SPINNING
Volume 1 – Technology of Short-staple Spinning
This deals with basic, generally valid, technological relationships in short-staple spinning. Subsequent volumes are organised according to machines or machine groups. This separates generally valid basic principles from ongoing developments in machine design and construction.
Volume 2 – Blowroom & Carding
In-depth information is provided on opening, cleaning, blending and carding and additional aspects are covered such as acclimatisation of raw materials, anticipated waste from various grades of fibre, selection and setting of cleaning and blending machinery, waste recycling, transport and the functions of the various card components as well as selection and maintenance of card clothing and autolevelling systems.
Volume 3 – Spinning Preparation
Here the technical and technological aspects of the yarn production process between carding and ring spinning are covered, that means draw frame, combing section (including combing preparation) and roving frame. This is an important process stage, because the yarn quality largely depends on the quality of the intermediate products from which it is made.
Volume 4 – Ring Spinning
Technical and technological aspects of ring spinning are covered. This is the final process in yarn production. The ring spinning machine greatly influences the yarn and its quality. Ring-spun yarns still represent the standard for comparison when evaluating yarns produced by other spinning processes.
Volume 5 – Rotor Spinning
This process resulted from research into alternative spinning systems. This volume contains in-depth information on the rotor spinning process and its properties. Continual improvements in spinning elements and conditions make it now possible to spin a rotor yarn optically similar to a ring-spun yarn.
Volume 6 – Alternative Spinning Systems
To take full advantage of alternative spinning systems, a thorough understanding of them is therefore essential. This volume contributes towards reaching this goal by describing the most important alternative spinning systems in detail. One of them is the well known Air-jet spinning technology.
Volume 7 – Processing of Man-Made Fibres
Ever since the introduction of man-made fibres on a commercial scale, the market share of synthetic fibres has shown an impressive growth rate. In this important field, the variety of man-made fibres with different properties is continuously increasing. For numerous applications today, fibres that are practically “tailor-made” are available. Spinners must therefore have detailed understanding of the fibre properties and the specific characteristics that affect their processing.
EDITORIAL
„Blowroom & Carding” is the second volume in the series The Rieter Manual of Spinning, which updates the essential principles in modern short-staple spinning. It endeavors to describe the contemporary state of the art in spinning technology, with the objective of providing a reliable overview of currently available processes and techniques.
This volume and the subsequent ones are designed to contribute to the achievement of that goal. Taken together, the seven books of the Rieter Manual of Spinning will thoroughly cover the topic of short-staple spinning.
The second volume outlines detailed information on the preparatory processes of opening, cleaning, blending and carding. It covers practical aspects such as use and preparation of raw materials, waste removal and anticipated waste quantity from various grades of fiber, selection and setting of cleaning and blending machinery, recycling of waste, transport and feeding of material. It also deals with the functions of different components of the card, selection and maintenance of card clothing, and auto leveling systems. Background data explaining the tremendous progress and increase in card productivity is provided together with an outline of options and potential in process integration.
The main author of these books, Werner Klein, is a former senior lecturer of the Swiss Textile College and author of the original edition of the „Manual of Textile Technology“ published by The Textile Institute Manchester. All further authors are textile industry experts, who among others in various positions within the Rieter Company, have many years of experience to their credit. The Manual also addresses aspects that extend beyond Rieter’s current product range, taking processes and solutions developed by other manufacturers into account.
The structure of this manual and the organization of its subject matter were taken over from the original Technology of Short-staple Spinning published by the Textile Institute, Manchester, whom we thank for their kind permission to continue this standard work.
We wish all users of this compendium pleasant reading.
