The forces exerted on fibres during drafting in the drafting zone with the upper and bottom aprons of the Ring Frame significantly impact the yarn quality. Aprons are crucial in manipulating fibres by facilitating movement and directing them toward the primary drafting area. From these two aprons, the bottom apron's tension is changed by changing tension spring bar groove hole positions. There is no scope for changing such settings in the case of top aprons. This research aims to achieve high-quality cotton carded knit yarn by selecting an appropriate bottom apron tension due to the significant role in proper drafting and twist insertion at the time of the manufacturing process directly affecting produced yarn's strength, evenness, imperfections, and hairiness properties. To fulfil this requirement, six yarn samples are produced each time by using 5 different tensions of the bottom drafting aprons. The samples underwent quality parameter testing, including Unevenness (U)%, Coefficient of Variation (CV)%, Imperfection Index (IPI), Hairiness (H), and Count Strength Product (CSP). The findings indicated that increasing the tension of the bottom apron while maintaining positions 1, 2, and 3 reduces the occurrence of neps, variations in thickness and thinness, and imperfections. In contrast, CSP is increased due to elevated stress on the fibres. In general, maintaining an appropriate tension enhanced the quality of the yarn, and the best quality was obtained for position 3, considering all the quality variables. Moreover, by using Interpretive Structural Modelling (ISM) methodology, the pairwise relationship between the quality variables is shown. Finally, after calculation, those quality variables are arranged in three levels. According to this level, the quality parameters are ranked where the top is the highest. It is observed that Count Strength Product is at the highest level, which indicates that CSP should be given more priority. Moreover, the end use of this yarn is to produce knit items, and for the knitting yarn, CSP is one of the most influential quality variables.

“…Every step of the process should be verified according to the customer's requirements based on the combined information of the various fault detection techniques. During the testing [12], it should be possible to measure each parameter of the yarn according to the technologies developed, such as the artificial neural network model and modeling and simulation in the appropriate software. The soft wastes from spinning were used to create fiber blends from yarn waste and fabric clippers reclaimed from yarn waste.…”

Yarn manufacturing in spinning mills is done when the twisted length of fiber goes to cheese, doubling, and winding machines. The humidity and temperature must be maintained to ensure the yarn quality. The conveyor belts have to be monitored continuously to avoid the interruption of the belts. This paper provides a solution to maintain the precise range of humidity and temperature and also to surveil the conveyor belts. The system contains a DHT sensor and an IR sensor. If the DHT sensor detects the increase in the moisture level or temperature, the signal is sent to the controller, and using a relay, either the heater or the cooler is activated respectively. The humidity level and the temperature of the yarn are displayed on the LCD. Simultaneously, the values can also be viewed on the user’s mobile application Blynk using an IoT. Another feature of this application is the continuous monitoring of the conveyor belt. If the belt stops, the IR sensor detects it, and the user is alarmed by a buzzer indicating that action is required to restart. This method reduces yarn breakage and improves the quality of the yarn. It provides continuous monitoring; the IoT application provides real-time values.

A concern in the contemporary period is to find balance in the world's ever-increasing demand and its severely constricted output given by the present energy crisis brought on by the post-pandemic and ongoing Russia-Ukraine war. One of the most fundamental human needs is met by the production of textiles. Spinning is the first step in the production of textiles, where the ring frame machine is essential for creating yarn. In this study, a few process parameters were altered in a ring frame machine to boost production while saving time and ensuring financial feasibility. Comparative analysis was performed based on financial aspects as well as quality concerns like yarn count variation, Count Strength Product (CSP), and end yarn breakage rate. The increased machine speed of the spinning ring frame consumes higher energy but yields higher productivity without compromising quality parameters. The findings enable the spinning industry's decision-makers to understand better how process parameters change when machine speed varies, as well as offer policymakers a clear picture of the correlation between energy consumption and profitability. The machine produces roughly 420 kg/day consuming 567 kWh of energy at 14000 rpm, with 2.57% breakages/100 spindles/hour of 18.48 tex count variation and CSP of 1320. However, the production and energy usage of a machine at 15000 rpm, is approximately 449 kg and 630.44 kWh/day. Respectively, with breakages 3.06%/100 spindles/hour of count variation 18.62 tex and CSP of 1325. A potential increase in profit of 112.58 USD/machine/day, or 9682 BDT resulted from the increase in machine speed.
