This paper introduces a new and flexible spinning method that is modified on a rotor spinning machine. The modification is implemented by a novel mechanical system specially designed to incorporate three separate feed rollers side by side and controlled by servo motors with programmable logic controller (PLC). Using this new method, yarn structure parameters including linear density and blend ratio can be controlled and realized by asynchronous drafted slivers. Sixty-six types of color blended yarns were produced by controlling blending percentages of three basic colored slivers (magenta, yellow, and cyan) by changing the feeding speeds of the slivers respectively with constant yarn linear density and color. Surface morphologies, blending effects, and performances of the yarns were tested and analyzed. In addition, fancy yarns including slub yarn, period melange yarn, gradient melange yarn, and color pointed melange yarn were produced and their longitudinal morphologies were taken. The results demonstrated spinning feasibility and product variety of the three channeled rotor spun process.

Rotor Spun Yarn

Color blended rotor spun yarn mixing with different methods were spun. Three blending methods were used, one passage of drawing, three passages of drawing and rovings during multi-channel spinning. Multi-channel spinning is modified on rotor spinning machine, which is implemented by a novel mechanical system specially designed to incorporate three separate feed rollers side by side and controlled by servo motors with PLC. Using this new method, blend ratio of yarn can be controlled and realized by asynchronous drafted rovings. 37 type of color blend yarn were produced with different blending ratios. And each yarn was intercepted with 5 cross sections and a total of 185 cross-sectional images were taken. Hamilton index of different colored fibers were calculated of the each type of yarns. And sum of absolute values of Hamilton index were got to demonstrated fibers blending effect in yarns cross sections. All the Hamilton index of the yarns prepared by the three above mentioned methods were all around 5, much below 20. The results showed that regardless of blending method used, the blending effects of rotor spun yarns were all very good.

End Use

This study investigates the effect of the blend ratio on recycled blended yarn quality characteristics. Ring-spun yarns of linear density of 23.6, 29.5 and 39.4 tex were produced from five blend proportions of recycled polyester and cotton (0:100, 33:67, 50:50, 67:33 and 100:0). Increasing the recycled polyester content increases the tenacity, elongation at break and hairiness and decreases unevenness, thin places, thick places and neps, while a decrease in linear density increases the tenacity, elongation at break, unevenness, thin places, thick places, neps and hairiness. Statistical analysis reflects that both the blend ratio and linear density have a significant difference on the tenacity, elongation at break, thin places, thick places, neps and hairiness. However, with reference to unevenness, a significant difference is reported only for linear density and not for the blend ratio. The ratio of recycled polyester has a significant influence on the overall quality of recycled polyester/cotton blended yarn. The blending of recycled polyester and cotton can be optimised to meet various end-use requirements.

And Performance

The fabric of colored spun yarn has ever-changing appearances and styles with different fancy yarns. The fabric image is commonly designed by the designer using the software, which needs complex user interactions and difficult image segmentation. In this paper, a modified color transfer method was proposed to generate the fabric appearance of colored spun yarn. Given the color card as the target image, the style fabric image was matched as the reference image based on the dominant luminance. After transferring the two images to lαβ color space, Wavelet transform and luminance sampling were utilized to filter the redundant high-frequency information and select the representative pixels, respectively. Then, the chromatic channels were transferred based on the best matched luminance and the neighborhood relation. Finally, the image after color transfer was reconstructed by wavelet reconstruction. The proposed reference image matching maintained the result to be the ground truth. For the samples selected, the combined methods based on wavelet transform and luminance sampling improved the efficiency and performance of the proposed scheme. Experiments were conducted on different fabrics with different colors and styles. Experiments demonstrated the validity and superiority of the proposed method, which can provide referential assistance for the designer and save considerable amounts of labor.

Test Result

Use of nylon/cotton blend yarn in military uniform is common and due to advantages in its fabric in comparison to 100% cotton fabrics, capabilities of military uniforms have been improved. In this study the effects of navel type on properties of (50%-50%) nylon/cotton blend yarn and wrapper formation were investigated and compared with similar ring spun yarn. Rotor spun yarn was produced on a single head laboratory rotor spinning machine with four navels (smooth, spiral, 3 grooved, and 4 grooved) and ring yarn was produced on a zinser 319 ring spinning machine. Test result showed that navel type has a significant effect on yarn strength and strength of smooth navel yarn was maximum. Elongation of a 100% cotton rotor spun yarn is more than similar ring yarn, but it was not observed in cotton/nylon blend. Yarn irregularity and imperfections varied significantly with navel type and for rotor yarns were more than the ring yarn. Navel type had significant effect on yarn hairiness but it didnot have an effect on yarn abrasion significantly.

And Performance

A miniature sorting of material quality has been made, aided by a prototype of the controller system based on the Mitsubishi FX1N-24MR Programmable Logic Controller (PLC). A number of stages include the manufacture of the conveyor system unit, the electrical system, PLC programming, and performance measurement. The conveyor unit assembling was processed by installing the conveyor belt, dc motor, pneumatic cylinder, solenoid valve, and sensors. The electrical system is an integration of the Mitsubishi FX1N-24MR PLC, switched-mode power supply, miniature circuit breaker (MCB), dc voltage regulator circuit, relays, digital counters, pushbuttons, and selector switches arranged in a 20 x 30 x 15 cm panel box. Mitsubishi PLC system programming is based on algorithmic determination and ladder diagram arrangement assisted by GX Developer (GX Work). Performance measurement in the form of pulse readings is carried out by setting and manufacturing ladder counters and shift registers to count the number of pulses for each material and the accuracy of sorting when the material is detected simultaneously. The system performance is indicated by pulse reading accuracy and sorting timing accuracy. The reading of the pulse from the proximity switch affects the counter calculation to activate the pneumatic cylinder unit in sorting. Sorting for material-A takes 11 pulses, while for material-B, it takes 19 pulses. The synchronization measurement functions when an error occurs in the system in order to maintain the input received is the same as the output in the PLC-based control system.

Rotor Spun Yarn

AbstractThis article provides three models to predict rotor spun yarn characteristics which are breaking strength, breaking elongation and unevenness. These models used noncorrelated raw material characteristics and some processing parameters. For this purpose, five different cotton blends were processed into rotor spun yarns having different metric numbers (Nm10, Nm15, Nm18, Nm22, Nm30 and Nm37). Each count was spun at different twist levels. Response surface method was used to estimate yarn quality characteristics and to study variable effects on these characteristics. In this study, predicting models are given by the analysis of response surface after many iterations in which nonsignificant terms are excluded for more accuracy and precision. It was shown that yarn count, twist and sliver properties had considerable effects on the open-end rotor spun yarn properties. This study can help industrial application since it allows a quality management-prediction based on input variables such as fibre characteristics and process parameters.
