PRODUCTION LINE OVERVIEW
Nanhai Laboratory is designed for most tests of spunbond and
SMS material.
It is one of the best labs in the PGI world wide.
Main material and its Property
•聚丙稀 PP 结构式是 [-CH-CH2-]n CH3 PP 的软化点大约是133度, 熔点为160-200度, 通常是173度 (等规PP) 熔融指数MFR或MI: 纺粘用一般20-50(我司用的一般在35左 右)
熔喷用一般为600-2000(我司用的一般在800-1800之间)

10、单体阀门位置控制不好 11、冷却风温度太高 12 切片湿 13、熔指太低
9.
风道底密封圈密封不好
折边产生的原因
1.
有熔点 分丝风道门有挂丝
2.
3.
4. 5.
网带上有熔点
网带速比不好 有丝挂在风道两边
破洞(稀网)产生原因
1. 2.
有新的小熔点 网带上有熔点
3.
• 所用的添加剂以母粒形式, 其MI 范围可适当大一些,因加
入量较少,一般对生产没有大的影响
纺粘无纺布的生产流程(SPUNBOND FLOW)
•原料(PP+母粒)投入( 混合 ) → 螺杆熔融→
量泵计量→ 模头纺丝→ 冷却牵伸→ 分切
过滤→

分丝铺网→
热轧
粘合→ (上油剂)→
卷绕 →

喷丝板温度不够 喷丝孔出丝不畅 密封圈漏气 风道面凹凸不平,漏风 风道面有太多单体 风道门缝漏风 风板太脏 风板两端封条贴得不好
克重计算与影响因素
RPM x 每转的单位重量=网带速度x 60
x 幅宽x 克重/1000
RPM=克重X网带速度x 60 x 幅宽x 克重 /1000/7.6(二线) 克重的决定因素:
1. 计量泵 2. 网带速度
克重均匀性的影响因素
1. 温度 2. 模头压力 3. 风板的干净度
4.补充风网的干净度
