Analysis of new five-element-integration spinning technology based on human-machine-material-method-environment for carbon neutralization

Conventional spinning process is characterized by its long scattered processes and labor intensiveness,causing problems such as high energy consumption per unit production,poor product consistency,and high operating cost.In addition,multiple-type-fiber spinning leads to difficulty in fiber recycling from raw materials and resultant products.As an effort to achieve the goal of carbon peaking in 2030 and carbon neutrality in 2060,this paper establishes a low-carbon spinning strategy as carbon neutralization spinning by integrating human-machine-material-method-environment.In specific,the intensive,simple and the extensive types of low-carbon spinning technologies were analyzed.The analysis results show that after comparison with conventional ring spinning,the intensive intelligent technology achieves low-carbon and high-quality spinning by reducing operation costs by 32.67%,production energy consumption per unit by 17.5%,and product defect rate by 61.54%,effectively addressing the problems in the spinning sector.The simple type can shorten or eliminate steps in the spinning process,achieves spinning speed as high as 550 m/min,realizing the goal of efficiency-improvement and emission-reduction.The extensive type spinning develops a front-end raw material functional recycling to change waste into treasure,reducing energy and emission.The extensive type also develops medium-end carbon-nesting spinning to produce green functional yarns,and resultant manufacturing technology can be used for producing cooling,heat-insulting functional yarns for green terminal textiles.
