LOW-ATTENDANCE SHIFT THROUGH AUTOMATION.

Rieter automated equipment reduces labor requirements during night and Sunday shifts at the Kunz spinning Mill in Linthal, Switzerland. The Kunz Mill operates 17 G5/2 ring spinning machines. Each spinning machine is equipped with a Robodoff for automatic doffing, two Robofils for thread piecing and machine monitoring, a Robocreel for rovi..

Automated sliver piecing up for improved quality in cotton spinning (German)

The automated can transport systems industrially produced to date require a manual operation as a rule - manual rubbing - in piecing up sliver again into the process. This is not only practised in piecing up sliver prior to another process but also in repairing sliver breaks. This operation is a non-reproducible process, which can have an..

Yarn neppiness -influence of raw material quality and process technology (German)

Neppiness influences the appearance of yarn, and consequently the quality of fabrics, especially in terms of dye uniformity. Neppiness is influenced by the quality of processed raw materials and the technological process. An investigation into nep size and distribution, the number of neps and changes in nep characteristics is presented.

Soft handle and resilience

Discusses production, properties and markets for North Country Cheviot wool. There a basically five different qualities for different end uses. Generally, the longer-stapled wool goes into worsted spinning systems and the shorter length staple into woollen spinning. The finest and softest is used to produce yarn for speciality unitwear. A..

Quickspin-method - a praxis-proved method for qualification of raw material

The raw material in the spinning mill causes the main part of costs at yarn production. According to spinning method and yarn count, more than 50% of the costs for yarn production are caused by raw material costs. For this reason the raw material is the essential feature with regard to an economical operation of a spinning mill and yarn q..

Yarn CAD: Prototyping of Yarn Samples.

The dynamic modeling of yarn deformation comprises both mathematical and graphical simulations. In January 1996, De Montfort University launched an investigation into the different types of yarns resulting from different manufacturing environments and processes. Mathematical simulation concentrated on the torsional effects of fiber assemb..

Solospun, Single Wool Yarns Weavable in Warp.

Solospun yarns are a versatile and cost effective alternative to two-ply yarns. Solospun yarns offer such advantages as efficiency, productivity, and return on investment. Because there are no twisting costs, overall yarn conversion costs are reduced. For example, an Nm 32/1 Solospun yarn would be 55 percent less costly than a conventiona..

Processing of Lyocell in spinning (German)

Lyocell regenerated cellulose fibres are discussed and the ring spinning and rotor open-end spinning of these fibres in blends with cotton is examined. The use of Lyocell fibres tends to reduce manufacturing costs. High spinning speeds can be achieved on ring and rotor spinning machines. For finer yarns and a rotor diameter of 30-32 mm sp..

Conventional and modern spinning methods. . .

The conversion of fibre to yarn, the spinning process is probably the most important step in textile production. This article gives an overview of the major yarn-producing systems including; ring spinning; rotor spinning; friction spinning; air-jet spinning; and wrap spinning. It concludes with the observations that: rotor and ring spinni..

Compact spinning -- A True Innovation in Staple Fibre Spinning.

Although compact spinning uses existing ring spinning components, it is considered an innovation because of its better raw material utilization, increased productivity, improved quality, and patentability. An advantage of compact spinning is its pneumatic compaction, which eliminates the spinning triangle that forms after the drafting uni..
