Assessing the Impact of Speed Change on Energy Consumption and Productivity: Investigating Ring Frame Process Parameters

Abstract

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.
