The main goal of using dual core spun yarn is to take advantage all properties its different components. Dual-core yarns comprising three components are currently in vogue. They combine the pleasant wear elastic with high dimensional stability. production these a challenging process even at spinning stage, but they making demands market. Such stretchable produced modified Ring frame. In this sy...

The final attenuation and twisting of fiber take place at ring spinning machine hence its optimized performance is very crucial in terms yarn quality. Drafting has a decisive effect on There exist many influencing parameters the geometry that have to be for manufacturing quality yarn. present research work was carried out develop Artificial neural networks (ANN) based prediction model polyester...

Two hydraulic spray nozzle systems, a flat fan and a high-pressure hollow cone, were used for ultra-low-volume application of the mosquito adulticide fenthion under a multiple swath scheme. Eight swaths at 322-m intervals were applied from a height of 91 m to simulate operational conditions. Deposition, effects on nontarget organisms (fiddler crabs), aerial flux, and mosquito (Ochlerotatus taen...

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...

To enhance the production efficiency of ring spinning and reduce the tension in the spinning process, the system which installed the balloon control ring on the ring spinning machine to control the balloon configuration of the yarn in the spanning process and control the tension in the spinning process was designed in the article. The system is the automatic control system based on PLC (Program...

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...

Besides its decorative handicraft antiques and other conventional uses, the importance of bamboo crop has been increased due to its use in textiles as a vegetable fibre. The absorbent nature of bamboo fibre has lead to its various applications in textiles. The focus of present research is to optimize the quality of bamboo/cotton blends. Therefore, present study investigates the influence of bam...

A common problem in production of core–spun yarns on the Ring spinning frame is the slippage of the staple fibers as sheath fibers relative to the core. This effect is known as ‘strip-back’ or barberpole. This problem may lead to an incomplete core coverage and results in end–breaks in subsequent processing. In order to avoid this problem, in the present work, core spun yarns (acrylic sheath fi...
