Chenille yarn has an increasing share of use in the upholstery fabric sector recently. To have important place chenille production world, it become necessary for manufacturers to improve quality, durability, and performance their products carry out innovative studies this field. Increasing abrasion resistance yarns that form basis fabrics will significantly affect service life performance. In s...

n this study, we have investigated the effect of weaving structure on Efficiency properties upholstery woven fabrics. Different four structures been produced in samples. To Enhance through weavestructure terms (friction, pilling, thickness, weight, and tensile properties), chenille yarns were used as weft yarn. All samples tested for fabric friction, properties. The results indicate that has a ...

In this study, it is aimed to establish an optimization model that minimizes the seam slippage in chenille upholstery fabrics using recycled and virgin polyester yarns. For purpose, 32 yarns were produced two different pile lenghts by r-PET binder / or structure then, these used as weft produce fabrics. Tests have been performed accordance with standards determine physical performance propertie...

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...

Yarn hairiness is one of the key parameters influencing the quality of yarn.It is observed that yarn quality has been deduced based on yarn length and diameter only. But these parameters do not provide much information about yarn quality. Thus it is proposed to derive more yarn quality parameters like yarn hairiness, uniformity of yarn and its thickness. In textile industry, image processing is...

The evaluation method of yarn surface quality currently in use is mainly based on manual inspection. In order to resolve the inherent limitations of the human visual inspection, an intelligent evaluation system has been developed for the objective and automatic evaluation of yarn surface quality with computer vision and artificial intelligence. In this system, all yarn surface features are full...

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...

Yarn-based supercapacitors having improved performance are needed for existing and emerging wearable applications. Here, we report weavable carbon nanotube yarn supercapacitors having high performance because of high loadings of rapidly accessible charge storage particles (above 90 wt% MnO2). The yarn electrodes are made by a biscrolling process that traps host MnO2 nanoparticles within the gal...

In this paper, a new yarn evenness measurement method based on machine vision is introduced, which is a direct measurement process, as opposed to other methods. Two types of yarns (i.e., same yarn count but different quality grade and same quality grade but different yarn count) are measured to determine the coefficient of variation unevenness, which can be compared with the results of USTER ME...
