Production Practice of Pure Cotton Carded 14.6 tex Compact Yarn
In order to improve the yarn quality of pure cotton carded 14.6 tex compact yarn,the spinning process parameters are optimized from three aspects of roving twist factor,spinning back zone drafting ratio and spinning front roller gauge,and the yarn quality of on-board test spinning is compared.By comparing the yarn quality of YYC-570Ⅴ cot and a domestic cot with shore A hardness of 68 degress after twice regrinding to select the spinning accessories.The re-sults show that the yarn quality of pure cotton carded 14.6 tex compact yarn is improved by u-sing YYC-570Ⅴ cot with roving twist factor of 118,spinning back zone drafting ratio of 1.05,spinning front roller gauge of 16.8 mm.The use of YYC-570Ⅴ cot can help enterprises to re-duce labor intensity of employees,reduce material consumption and improve work efficiency.Optimized spinning process and accessories and parts,and strict management can ensure stable yarn quality.
