摘　　要：为优化颜色预测模型,引入织物紧密程度常数,探究色纺针织物紧密程度对颜色预测的影响。采用红和蓝2种色纤维织造不同紧密程度的织物,选用常用的Stearns-Noechel模型为颜色预测模型,求解模型中的待定参数M时,以拟合色差最小时的M值为最优参数,对比引入常数前后的预测结果。结果表明:未引入织物紧密程度常数时,所得到的M值较引入常数后得到的M_(p)小;当织物组织相同时,随着织物紧密程度逐渐变小,M值变化很小(0.2265~0.2216),而M_(p)值却有逐渐增大的趋势(0.2921~0.3471);当弯纱深度一致时,M值随着织物紧密程度的增加,有变大的趋势,但M_(p)值变化趋势却不明显;引入织物紧密程度常数后,预测平均色差都更小。In order to improve color prediction modeling,this research took fabric tightness into consideration,and then the influence of the tightness of the fiber-colored knitted fabric on the color prediction was studied.Red and blue pre-colored fibers were used to produce knitted fabrics with different tightness.The fabric surface porosity was used to describe the fabric tightness,and Stearns-Noechel model,one of the most commonly used color prediction models,was selected to predict the color of fabrics.When computing the unknown parameter M in the prediction model,the value of M corresponding to the minimum predicted color difference was selected as the optimal parameter.The results show that when the fabric tightness was not added,the M values obtained were smaller than that of the M_(p) which were computed when the fabric tightness value was added.When the fabric structures were the same and the tightness of the fabric gradually decreased,the M values hardly change(0.2265-0.2216),whereas M_(p) increased gradually(0.2921-0.3471).When the sinking depth of yarns was kept constantly,the M values increased as the fabric became tighter,but the changing of M_(p) is not obvious.It was obvious that the predicted average color difference became smaller after adding the fabric tightness as a constant into calculation of M.
