Raw material and costs Raw material and energy costs are the two predom- inant parameters in a spinning mill’s cost calcula- tions

Savings on raw material – a  reduction in comber noil in this case – directly affect raw material costs for the yarn in question Lower yarn twist and the re- sulting increase in output at the same spindle speeds reduce energy costs for the compact yarn by  Since energy accounts for  of the manufactur- ing costs a total cost reduction of  was achieved

  • Table 

Cumulation of the savings calculated above results in a  reduction in total production costs On the basis of today’s yarn prices these savings in resourc- es increase the spinning mill’s net return on sales by almost 

Conclusion The study shows how the qualitative benefits of com- pact yarn can be exploited profitably by both spin- ning and weaving mills Even with savings in the manufacturing process reduced twist factor and raw material lower noil extraction compact yarn still has sufficient reserves in terms of yarn quality It still displays significantly better yarn and process- ing properties than a conventional ring-spun yarn Spinning mills benefit from reduced costs and down- stream processors from better processing properties Spinning compact yarns offers lower manufacturing costs with higher quality -
