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);響應面分析中圖分類號:TS101.2文獻標志碼:AInfluenceofyarnformationprocessonpropertiesofbamboopulpfibercoloredspunyarnusingairjetvortexspinningZOUZhuanyo
