Tube spinning of viscose fibres

Conclusions Tube spinning of viscose fibres makes it possible to reduce the hydrodynamic frictional resistance of the precipitation bath.The possibility is created of raising spinning speed, increasing the number of spinneret holes, and raising fibre quality.On use of tube spinning, questions of reducing gas contamination of the working zone and mechanizing spinneret replacement are solved more effectively.Translated from Khimicheskie Volokna, No. 2, pp. 8–13, March–April, 1986.     

Directed structure-formation during spinning of viscose fibres

Conclusions 1. Fibre spun in coagulating bath containing zinc ions, in conditions which exclude any mechanical effects on the fibre, exhibits anisotropic properties (birefringence). This is caused by the directed structure-forming effect of the zinc ions (ionotropic effect).2. When such a fibre is deformed by stretching or shrinkage the orientation achieved is the sum of two components: the orientation due to directed structure-formation, and the orientation caused by deformation.All-Union Scientific Research Institute for Man-Made Fibres.

A spinning disk for a machine for spinning viscose fibres

Conclusions A spinning disk of the described construction ensures obtaining a viscose fibre which conforms to the requirements of technical conditions, is easily removed from the spinning machine spindle, and can be disassembled without breakage.The spinning disk construction ensures reliable and simple centering on the spinning machine spindle and ensures an insignificant wobble of the working surface relative to its axis of rotation.Translated from Khimicheskie Volokna, No. 3, pp. 50–51, May–June, 1983.     

Evolution of carbon disulfide and hydrogen sulfide in spinning viscose fibres

Conclusions It has been found that the rate of decomposition of the byproducts and of cellulose xanthate differ considerably from the rate of evolution of the gases formed.Carbon disulfide in the chemically unbounded state forms stable emulsions with the components of the precipitation bath.The kinetics of carbon disulfide evolution in the plasticizing treatment of viscose fibre is described by a zero order reaction equation.Translated from Khimicheskie Volokna, No. 6, pp. 44–45, November–December, 1985.     

Effect of the conditions of spinning viscose textile fibres on their properties

Rigorous respect of the standard character and purity of the spinning solution, spinning bath parameters, and orientation draw ratio ensures obtaining a complex fibre homogeneous over the length. By varying the flow rate of viscose from the spinneret and disk rotation, it is possible to vary the fibre tension, strength, elongation, and shrinkage within wide limits and ensure a high capacity for uniform dyeing. The limits of the overall draw ratio of viscose textile fibres of varying assortment without elementary fibre breakage and formation of nap were established. __________ Translated from Khimicheskie Volokna, No. 6, pp. 28–31, November–December, 2005.

Some aspects of spinning fibres from fluorine-containing copolymers by melt extrusion

Conclusions The following special features have been found in spinning fluorine-containing fibres: a small length of the deformation zone and a high degree of preliminary orientation.The advantages of spinning fibres from CP TFE-E or CP TFE-PFAVE as compared with other thermoplast fluorinated monomers consist in a high stability and speed of spinning.Translated from Khimicheskie Volokna, No. 2, pp. 28–30, March–April, 1986.

Special features in spinning fine viscose textile yarns

Conclusions Conditions which assure stability of the process of spinning a complex viscose yarn with an increased number of elementary filaments have been determined.It has been shown that stability of the process of spinning complex viscose textile yarn of 13.3 tex linear density with an increase in number of elementary filaments (>60) is increased on reducing the jet stretch, reducing the diameter of the spinneret holes from 0.09 to 0.06–0.05 mm, and bringing the distance between them from 1.4 to 0.5 mm.Translated from Khimicheskie Volokna, No. 3, pp. 39–40, May–June, 1984.
