A Statistical Analysis of Yarn Breakage on Spinning Frame
The problem of yarn breakage during spinning is quite serious, but it is difficult to predict the number of yarn breakages, because the tension and strength of the yarn always vary. The author has used simple mathematical models of the variation of the tension and the strength of the yarn, and calculated the probability of yarn breakages. The result has shown that the variation of the yarn stre...
متن کاملYARN: Spinning-in-Progress
YARN (Yet Another RussNet), a project started in 2013, aims at creating a large open WordNet-like thesaurus for Russian by means of crowdsourcing. The first stage of the project was to create noun synsets. Currently, the resource comprises 100K+ word entries and 46K+ synsets. More than 200 people have taken part in assembling synsets throughout the project. The paper describes the linguistic, t...
متن کاملA Study on Spinning Limits and Yarn Properties with Progressive Change in Yarn Count in Friction Spinning
The spinning limit for three different fibres (cotton, viscose rayon and polyester) on a Dref-3 friction spinning machine has been investigated. The change in yarn properties with progressive change in count has also been reported. The count range has been seen to be dependent on fibre type. As one progresses from very coarse to fine counts, the yarn tensile property remain fairly unaltered for...
متن کاملThe Effect of Yarn Hairiness on Air Drag in Ring Spinning
Air drag on yarn and package surfaces affects yarn tension, which in turn affects energy consumption and ends-down in ring spinning. This paper investigates the effects of yarn hairiness on air drag in ring spinning. Theoretical models of skin friction coefficient on the surface of rotating yarn packages were developed. The predicted results were verified with experimental data obtained from co...
متن کاملCommingled Yarn Spinning for Thermoplastic/Glass Fiber Composites
Online commingled yarns were spun with three different polymeric matrices, namely polypropylene (PP), polyamide (PA) and polylactic acid (PLA) and glass fibers. Tailored sizings were applied for the three matrices and the resulting mechanical performance of unidirectional composites was evaluated and compared. Significant improvements in the fiber/matrix bonding were achieved by employed sizing...
