摘要 The design guideline for the air suction drawing system with auxiliary air was analyzed,a spunbonding nonwoven system named PADHL1-3200 was designed and polypropylene(PP) spunbonded nonwoven fabrics with excellent properties were achieved after many trial runs.On the other hand,the suction air velocity(VA) was calculated and the influence of VA on the bonding strengh of PP nonwoven fabrics was studied as well.It was found that VA is 1.5-2.5 times of the spinning velocity.With the increase of VA,PP fibers become finer and the bonding strength of PP nonwoven fabrics increases as well.
