2、紗線的條下,而在紡制中、細特紗時負壓應適當減??;對于成紗強力,選擇較大的負壓有助于提高粗特紗的強力,紡制Lf
3、、細特紗應適當降低負壓;當負壓增大時,紗線的3mm以上有害毛羽逐漸減少。關(guān)鍵詞:全聚賽絡(luò)紡;窄心羅拉;集聚負壓;環(huán)錠紡中圖分類號:PS104.31;TS104.77文獻標識碼:A文章編號:1001-2044(2014)06—000—0Efectofconcentrationnegativepressureofcompletecondensingsiro-spinningonyarnpropertyZHUYukun,XIEChunping,XUBojun,LIUXinjin,S
