Air-jet weaving is an advanced weaving method with high efficiency and productivity. It is one of the most widely used methods of weaving in the world. In air-jet filling insertion, the motion of weft yarn is caused by friction between weft yarn and air blown through nozzle. After declamping and subjecting the yarn to air stream, its motion is not active but very complicated and influenced by ...

Yarn supercapacitors have great potential in future portable and wearable electronics because of their tiny volume, flexibility and weavability. However, low-energy density limits their development in the area of wearable high-energy density devices. How to enhance their energy densities while retaining their high-power densities is a critical challenge for yarn supercapacitor development. Here...

The objective of the study is to investigate the effect of introducing jute yarn on the mechanical properties of concrete. Jute fibre is produced abundantly in Bangladesh and hence, very cheap. The investigation on the enhancement of mechanical properties of concrete with jute yarn as reinforcement, if enhanced, will not only explore a way to improve the properties of concrete, it will also exp...

The aim of this research is to design a controlling loop that eliminates the irregularities in yarn tension during the winding process. In order to achieve this, we employed a relative feedback industrial control system. The yarn tension sensor measures the tension. Its output is analyzed in the automatic controlling unit. This unit adjusts the tension level according to feedback signals, thus ...

Woven cloth can commonly be seen in daily life and also in animation. Unless prevented in some way, woven cloth usually frays at the edges. However, in computer graphics, woven cloth is typically modeled as a continuum sheet, which is not suitable for representing frays. This paper proposes a model that allows yarn movement and slippage during cloth tearing. Drawing upon techniques from textile...

In this paper, the relevance of integrated planning concerning decisions production and blending in a spinning industry is studied. The scenario regards plant that produces several yarn packages over horizon. Each type produced using blend cotton bales must contain attributes to ensure quality yarns. Three approaches managing are compared; first deals with solution scheduling problems single mo...

A disabling chest disease characterized by bronchospasm (" byssinosis ") has, for many years, been recognized as affecting the workers in cotton blow rooms and card rooms (Collis, 1909), and has been attributed to inhalation of the airborne dust round the machines. It remains a serious industrial hazard in spite of measures which have been taken to reduce the dust, such as the improvement of ve...

Our results on the strength parameters of cotton yarns manufactured by carded and combed systems ring rotor spinning (CD-carded ring-spun, OE-carded rotor-spun, CM-combed ring-spun) are presented. Experiments to test for were conducted a “Statimat C” tensile installation at speeds lower end yarn from 100 mm/min 1000 mm/min. From diagrams stretching breaking, changes in breaking load, specific c...
