气流牵伸技术及其与成布质量的关系

Air-drawing Technologies of Spunbonding and Relations Betweem Them and Fabric Quality

本文重点阐述了纺粘法非织造布生产所采用的气流牵伸技术中喷嘴牵伸和窄缝牵伸两种不同的牵伸工艺，分析了不同牵伸工艺与产品质量的关系，提出了改进产品质量的工艺措施。

In the paper,two kinds of air-drawing processes that are a jet orifice drawing and a slot drawing for spunbonding are elaborated,the relations between the two kinds of drawing processes and the qualities of the fabric made by them are analyzed,and the process methods of improving the fabric quality are put forword.
