Developing a twist draft spinning system for small-scale production of special material yarns

This paper presents a new spinning system, a kind of twist draft spinning in which the withdrawal tension in yarn being spun out is used to control its count. This system produces the yarn directly from a large mass of fibers in a pot, can spin even low quality fibers that are difficult to spin with modern spinning systems, and is able to..

Characteristics of frotte fancy yarns

Ten types of frotte fancy yarn have been compared by statistical methods. They were produced with two different types of machines: the ESP-X hollow spindle machine and the PL3C ring twisting frame. All the yarns tested were produced from the same raw material, 167 dtex textured polyester filament yarn and 32x2 tex polyacrylonitrile staple..

Productivity in fine yarn packages

Introduces the high rate HPF and HPF-HS machines from Noseda Srl-Benefits of use of these machines over standard hydraulic machines are give, which include: reduced water channeling and associated-local-defects; reduced package deformation leading to easier rewinding; and capability of processing sensitive yarn and/or packages at medium t..

Resch: In-line yarn steamer

Resch Maschirenbau GmbH of Germany now has second generation models available of its successful Sewimatic E Yarn Steamer. The unit achieves advantages in twist reduction while maintaining strength and minimizing hairiness and fly. As well as increases in productivity, it improves drape and hand in the finished fabric. Resch steaming machi..

The essence and state of compact spinning (Bulgarian)

Methods of improving the compactness of yarn structure with a view to increasing their tenacity are considered. Ring spinning, air-jet spinning, rotor spinning, friction spinning and wrap spinning spinning are all briefly examined.

Studies on the tensile behaviour of nylon core-spun yarns

Core-spun yarns are defined, and the main objective of core spinning is to combine the aesthetic and comfort properties of natural fibres with easy care and strength properties of synthetic filaments. Double roving feed (DRF) is generally advocated for core spinning. This study attempts to establish the reinforcing effect of nylon multifi..

Retrofitting existing worsted spinning frames with the Suessen EliTe spinning system (German)

Two factors characterized the development of the market for high-quality worsted yarns over the last two years; moderate overall yarn consumption while on the other hand the market for superior yarn quality sets even higher quality standards to form an expanding sector. The demand for finest fibers for wool tops is discussed. Companies wh..

Core-spun yarns - Market of the future (German)

Core-spun yarns belong to the family of so-called multi-component yarns. Combining spun yarns and filaments with different yarn characteristics can provide new functional features. When spinning core-spun yarns, a filament core is covered with staple fibers. A distinction is made between soft-elastic core-spun yarns and hard, non-elastic ..

Electrostatic spinning - A new approach

The process of electro static spinning is used in open end spinning process for the insertion of twist as well as for better fibre control in a yarn. The Electrospin Corp. of the US developed the electrostatic in the late 1960s. The purpose of this work is to investigate the potentialities and limitations of break spinning as applied to t..

Significance of spinning triangle

The spinning triangle has a decisive influence on yarn surface, strength, elasticity, running performance and fly liberation. This article highlights the importance of spinning geometry; the spinning triangle and the techniques developed to eliminate it. Ideal spinning geometry makes constant, high-speed spinning of high-quality yarn poss..
