The idea of successful processing of textile fibres includes ensuring the passability of the fibre and high productivity of the technological process on the equipment in processing enterprises, decreasing the amount of production wastes to the minimum, obtaining high-quality articles, and creating safe working conditions. The fibre processing problem will be solved by f'mding the optimum set of basic technological properties --electrophysical, frictional, rigidity, and compactness --by controlling respect of these parameters and by eliminating environmental pollution and the toxic effects of the fibres.Treatment with textile auxiliary substances (TAS), which should lead to the high basic technological properties of the fibres indicated above, makes it possible to process Fenilon fibre by the cotton system of spinning to a significant degree. It is difficult to give a fibre the required set of properties with only one preparation, so the research focused on creation of bicomponent compositions. By varying the ratio of the components, it is possible to ensure the optimum properties as a function of the assortment and quality of the fibres.The TAS were selected in the following sequence. We fh'st investigated the physicoehemieal and surfact~nt properties of the individual preparations and compositions based on them which affect the uniformity of their application, and the technological properties and quality of the articles. Then we conducted studies of the basic technological properties. Nonthermally stabilized Fenilon fibre with a linear density of 17 tex was used as the model for investigation. The fibre was treated with solutions of the preparations by the method of contact on a disk or roller, or by the forced capillary method.Compositions with a hypothetical optimum set of properties were selected based on the laboratory data obtained. These preparations and individual preparations with extreme values of the technological properties were tested in a pilot plant.Processing was monitored based on the following indexes: electrification: visually based on bulking of the web (the fibre "stands on end") and sticking to machine parts; instrumental evaluation: based on the electrical resistance p of the fibre on an IESTV-1M instrument and the magnitude of the charge on a FD-06 transport device made in Hungary; elevated friction properties: visually based on clogging of coiler can channels in the mode of operating with a support, coiling on the working parts of the machines, end breaks in the yarn; decreased friction properties: visually based on clogging of coiler can channels in the mode of operation without a support in start-up; All-Russian Scientific-Research Institute of Synthetic Fibres, Tver'.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
