Features of the FCT 3000 continuous filament viscose rayon filament spinning machine are described. The spinning section includes the viscose feeding, filtration and extruding equipment, the spinning bath basins and glass tubes. The treatment and drying section and control system are examined and the take-up is considered. Future developm..

Experiments to determine the humidity of wool in the spinning process (Spanish) (Experiencias en la determinacion de la humedad de la lana en el proceso de hilatura)

Experiments were carried out to compare the use of a portable humidity meter and a drying cabinet to determine the humidity of wool at different stages in the spinning process - flock, sliver, roving and yarn. Much higher values of humidity were produced by the portable humidity meter. The results were influenced directly by interfibril p..

Spinnability of local merino wools (Bulgarian)

The effects of fibre length and fibre diameter on the spinnability of Bulgarian merino wools are studied. It is found that 60s wool gives slivers where the maximum fibre length is 76mm. In the case of 64s wool the maximum fibre length is 73 mm. similarly the minimum linear density for 60s wool is 30 tex; that for 64s wool is 25 tex. The m..

Combining open-end spinning with twisting

Volkmann GmbH and Co of Germany have patented a new concept in the process of yarn formation, where two rotating open-end positions each deliver separate yarns into a two-for-one twisting spindle. Although it is not yet at the commercialisation stage, the concept could lead to the creation of a new system of making folded yarns.

Jute and Jute Blended Yarn Spinning

An overview of studies at SITRA on technologies and products to revitalize the Indian jute industry focuses on jute cultivation, seed varieties, harvesting, fiber extraction, and retting procedures; jute fiber physical and chemical properties; ring spinning jute and jute blend yarns; the development of a high speed ring spinning machine f..

Developing a Twist Draft Spinning System for Small-Scale Production of Special Material Yarns.

An innovative tension control twist draft spinning system uses the withdrawal tension in the yarn being spun to control the yarn count. The system spins low quality yarn from a large mass of fibers in a pot that is otherwise difficult to spin and manufactures functional yarns from such specialized materials as carbonized cotton/polyester ..

Effect of an air-suction nozzle on yarn hairiness and quality

Various types and parameters of nozzles in the conventional ring spinning machine diversely impact yarn hairiness, which inevitably occurs during spinning. This research attempts to reduce yarn hairiness by designing an air-suction nozzle as alternatives to the commonly used air-jet nozzle, and attaching them to a conventional spinning ma..

Giesse SL2000 chenille yarn spinning frame (Italian)

Giesse, headquartered in Calenzano, near Florence, has designed the new SL2000 to increase output capacity and flexibility while reducing operational costs. The machine is controlled by a new electronic headstock, the frame cuts down vibration, the computer assisted control system is easy to use, and the frame/gears unit provides perfect ..

Yarn treating jet having a flow control plate

A jet for treating a yarn with a fluid has a flow control plate having a first and a second flow control opening. The flow control openings are located in the plated such that when the plate is mounted between the jet body and the manifold body, at least one, but preferably both, of the flow control openings in the plate at least partiall..
