Abstract The influence of Modal–cotton (MC) fibre blend ratio and ring frame machine parameters such as front top roller loading and break draft on the blended yarn properties has been studied. Compact MC blended yarn samples of 14.75 tex with three different MC fibre blend ratio has been produced in a LR 6 ring spinning frame fitted with Suessen Compact drafting system. A robust design optimisation to minimise the variations of the output yarn properties such as blended yarn tenacity, yarn unevenness and hairiness caused because of the variations in the material as well as machine setting parameters is achieved through the Taguchi parametric design approach. It is found that the maximum compact MC blended yarn tenacity is 23.76 g/tex, which is influenced very much by MC fibre blend ratio but meagrely by top roller loading and break draft. Similarly, the minimum 9.54 U% and 3.59 hairiness index are achieved with 100:0 and 70:30 MC fibre blend ratio, respectively, at 23-kg top roller loading. Statistical ANOVA analysis is performed on the results and optimum values are obtained within the 95% confidential level through confirmation experiments.

Humidified Air

In this study, the effect of 100% atmospheric relative humidity on yarn properties was investigated using jet-ring nozzles and compared with the yarn properties of yarns produced with air operated jet-ring nozzles under normal conditions. As a humidification system, a pneumatic conditioner, also known as a lubricant, was used in pneumatic systems. This conditioner was connected just before the pneumatic distributor that supplies air to the nozzles. The tube in stage 2 of the conditioner was filled with pure water at room temperature (25 °C ± 2 °C). The air conditioner dose was adjusted to 100% atmospheric relative humidity. The use of humidified air to jet-ring nozzles had a slight positive effect on all yarn properties (yarn hairiness, yarn irregularity, yarn elongation and yarn tenacity). According to the results, it resulted in a 1% to 3% improvement in yarn quality. This study is the first example and an original study in this field, as there is no study using humidified air in existing jet-ring air nozzle studies. It was proven in this study that humidified air results in a slight improvement in yarn properties.

To overcome the spun yarn unevenness deterioration and insufficient hairiness reduction for ring spinning with a static contact surface, this study introduced a modified method to improve spun yarn properties by contacting the spinning strand with the static rod and self-adjustable disk surfaces. The mechanism of the improvement of spun yarn properties was theoretically analyzed. Analysis results indicated that the combination of the static rod and self-adjustable disk surfaces could improve the yarn hairiness wrapping force without sever twisting blockage, resulting in a large yarn hairiness reduction and surface tight structure without irregularity deterioration. Correspondingly, the yarn tenacity should also become somewhat enhancement. Then, our theoretical analysis and prediction were validated by conducting such comparative experiments as spinning without a contact surface, spinning with a static rod surface, and spinning with a combination of the static rod and self-adjustable disk surfaces. The experimental results were in good agreement with our theoretical analysis and prediction.

This research work describes a new technique for producing staple fiber core-filament wrapped composite yarn, with the help of an innovative multifilament spreading method, using a slightly modified ring frame. The purpose is to develop an efficient and economic process for spreading the multifilament uniformly, to realize and improve the wrapping of the multifilament around staple core. Scanning electron microscopy was used to study the role of micro grooves’ dimensions in the formation of the multifilament layer and related effects on cover spun yarn properties. A modified ring frame was used to make 48 tex (12 Ne) composite yarn, which was compared to a similar composite yarn made on a conventional ring frame, for the tensile and hairiness properties. It was concluded that this mechanical spreading method can be used to increase the spinnability for short staple fibers and to overcome the problems associated with other spreading techniques and also can help to improve the breaking extension and hairiness properties of the composite yarn without the decrease of yarn tenacity.

The fundamental research work about the superconducting magnetic bearing (SMB) twisting system provides huge potential to eliminate the most important limitation of productivity, that is, the friction in the ring traveler system of the existing ring spinning process. As a continuity of the research work, the functionality of the SMB spinning has been carried out with different angular spindle speeds, yarn counts, and materials in order to determine the influence of the SMB technology. The current paper presents a comparative investigation of the yarn properties, such as yarn tenacity, yarn elongation, yarn evenness, microscopic views, etc., between conventional and SMB ring spun yarn. The intensive analysis confirms that the SMB system enables one to produce satisfactory yarn quality similar to that of conventional ring spun yarn up to 15,000 rpm. The influence of conventional and SMB spinning processes on yarn properties has been further analyzed statistically using an analysis of variance.

Yarn-dyed textiles complement digital printing textiles, which hold promise for high production and environmentally friendly energy efficiencies. However, the complicated structures of color-blended yarns lead to unpredictable colors in textile products and become a roadblock to developing nonpollution textile products. In the present work, we propose a framework of intelligent manufacturing of color blended yarn by combining the color prediction algorithm with a self-developed computer numerically controlled (CNC) ring spinning system. The S-N model is used for the prediction of the color blending effect of the ring-spun yarn. The optimized blending ratios of ring-spun yarn are obtained based on the proposed linear model of parameter W. Subsequently, the CNC ring-spinning frame is used to manufacture color-blended yarns, which can configure the constituent fibers in such a way that different sections of yarn exhibit different colors.

Spinning triangle is a critical region in the spinning process of yarn. Its geometry influences the distribution of fiber tension in the spinning triangle and the properties of spun yarns, such as the yarn breakage and hairiness. In this paper, the relationships between the spinning angle and yarn properties especially the yarn hairiness were investigated under various horizontal offsets. The properties of spun yarns produced by the modified system were evaluated and analyzed. Both left diagonal and right diagonal yarn arrangements were examined. The results indicate that the right diagonal yarn path leads to reduce yarn hairiness but the left diagonal yarn path leads to increase yarn hairiness; the breaking force of yarn changes little; yarn evenness deteriorates slightly with the changes of offset.

The Relationship

This paper experimentally studies the relationship between the friction surface of a false-twisting unit and the quality of cotton yarns produced by a modified ring spinning system, with the adoption of the single friction-belt false-twister. The friction surface of the false-twisting unit, as a key twisting component, has been studied in terms of material, surface roughness, hardness and diameter, as well as the interaction between these factors and resultant yarn properties, with particular attention to yarn imperfections. Experimental results showed that the false-twisting unit with a short interactive path demonstrated significant reduction of yarn imperfections, especially yarn neps. With the optimal false-twisting unit, performances of the modified yarns and their knitted fabrics were evaluated and compared with the conventional ones.

Purpose This paper presented a new kind of ring spinning frame with four pairs of rollers, and they are the front roller and the front top roller, the first middle roller (FMR) and the first middle top roller (FMTR), the second middle roller and the second middle top roller, the back roller and the back top roller. The FMR is the front roller of middle draft zone, and the back roller of the front draft zone. Therefore, the deformation of FMTR during spinning is an important factor for yarn quality, which was studied in this paper. Design/methodology/approach In this paper, by finite element method (FEM), the pressure and deformation of FMTR were studied. FMTR made from steel and sleeved carbon fiber were compared. 5.8tex, 4.9tex and 3.9tex cotton yarns were spun, and corresponding numerical simulations of FMTR pressure and deformation were presented in ANSYS software and comparatively analyzed. Then, corresponding yarn qualities were compared. Findings The results indicate that pressure and deformation of FMTR have little effects on yarn tenacity and hairiness, while have great effects on yarn evenness. For 5.8tex and 4.9tex cotton yarn, yarns spun by FMTR made from sleeved carbon fiber have larger pressure and deformation at the middle of nipper bites of FMR and FMTR, and yarn evenness is better. For 3.9tex cotton yarns, at the middle of nipper bites of FMR and FMTR, FMTR made from steel has smaller pressure. But deformation of FMTR made from steel is larger, and yarn evenness is better. Originality/value This paper studied pressure and deformation of FMTR by finite element method (FEM), which serve as a theoretical underpinning for yarn spinning in three draft zones ring spinning machine.
