提高L900膨体条缩率的生产实践

Process practices of improving L900 bulky sliver shrinkage

借鉴德国拜耳公司X800膨体条的生产经验,通过对拜耳公司L900丝束性能指标检验分析和生产工艺的可行性分析,以及在L900膨体条市场价格调研等工作基础上,利用QC系统分析、相关性分析、直方图等工具,在现有拉断法制条装备上,对L900丝束生产腈纶膨体条提高缩率的制条工艺进行优化。优化后,缩率中心值从20%提高到23%,很好地满足了顾客的要求,同时对成果进行了标准化处理,提高了企业的经济效益。

Based on the experiences of XS00 sliver from Bayer Company, by the analysis of production feasibility and property index examinations for L900 sliver and research work on its market price, by using Qc system analysis, eorrelation analysis, histogram and other tools, on the existing equipment of stretch-breaking method, and the production process for L900 acrylic bulky sliver to improve shrinkage rate is optimized. After the optimization, the shrinkage center value increases from 20% to 23%, and it meets the needs of the customer. The results are standardized and it raises the economic benefits of the company.
