Effect of Stretching - Setting Treatment on Dyeing Behavior of Wool

Changes of dyeing behavior of wool after stretching - setting treatment are studied.Effects of stretching - setting on wool structure are analyzed.It is concluded that stretching - setting treatment not only reduces wool diameter and increases wool length,but also brings about low-temperature dyeing of wool.

广陈皮的外观颜色客观量化及其陈化年份判别模型的建立

目的：依据色度分析原理对广陈皮外观颜色进行客观量化研究,为广陈皮的陈化年份鉴别建立新方法。方法：采用色彩色差计对广陈皮外观颜色进行客观量化研究。采用非参数检验、秩相关检验法和判别分析等统计学方法对陈化年份与L＊（明度值）,a＊（红绿分量值）,b＊（黄蓝分量值）之间的相关性进行分析。结果：不同年份广陈皮的色度值有显著性差异,且L＊,a＊,b＊与陈化年份之间分别存在线性相关关系。建立了基于L＊,a＊,b＊的广陈皮陈化年份的数学判别模型,陈化年份=-43.637L＊＋5.351a＊＋42.430b＊＋30.790。结论：建立的客观量化方法稳定可行,为广陈皮的陈化年份鉴别提供了一种客观量化方法,可避免因传统人为鉴别方法所带来的误差。
