减碳环保可染花灰赛络集聚纱工艺研究OA

To address the problems of frequent weft bar defects on single-dyed cotton fabrics and water pollution caused by dyeing and finishing processes,a carbon reduction and environmental protection dyeable heather siro compact yarn was developed.Firstly,solution-dyed polyester and natural-colored cotton were selected for blending,circular blending and secondary lay-down bale arrangement were adopted to achieve more uniform blending of raw materials.Secondly,modifications were carried out on the E66 comber,and a combed sliver tearing and baling device was designed innovatively,which shortened the production process and improved manufacturing efficiency.Strict in-process control and quality inspection were implemented during production,all process parameters were optimized on the premise of minimizing fiber damage.Consequently,JC/T 60/40 14.8 tex carbon reduction and environmental protection dyeable heather siro compact knitting yarn was successfully spun.The prepared yarn presented a distinct and varied color pattern,rich in layers,high strength,few neps,a tight and smooth yarn structure.It fully met the requirements for subsequent weaving applications.This spinning process reduced water pollution and energy consumption during dyeing,saved energy and sewage costs.Meanwhile,it satisfied consumers' demands for environmental friendliness,personalized styles and diversified colors.
