2、主要受紡紗速度和紗線線密度影響，提高紡紗速度使紗線條干不勻先減后增，而減小紗線線密度將顯著惡化色紡紗條干；色紡紗毛羽主要受噴嘴氣壓和紡紗速度影響，降低噴嘴氣壓及提高紡紗速度均會(huì)使紗線毛羽增加；色紡紗直徑主要受噴嘴氣壓和紡紗線密度影響，增加噴嘴氣壓或減小紗線線密度，均會(huì)使色紡紗直徑明顯減小。關(guān)鍵詞噴氣渦流紡；色紡紗；工藝參數(shù)；響應(yīng)面分析中圖分類號(hào)：TS101．2文獻(xiàn)標(biāo)志碼：AInfluenceofyarnformationprocessonpropertiesofbamboopulpfibercoloredspunyarnusingairjetvortexspinningZOUZhuanyo
