双组分纤维熔喷非织造布及其潜在应用

熔喷法是全球范围内一种最通用和成本可行的能够大量地、有效地用热塑性树脂一步法制造微纤维非织造布的方法。在最近几年中 ,人们已逐渐关注研制双组分熔喷非织造布。基础研究工作已在纺织品与非织造布研制中心借助于自 1999年 3月安装的Reicofil双组分熔喷非织造布生产线上得以完成。试验了各种成分的热塑性树脂及其双组分复合的熔喷非织造布产品 ,包括单组分聚丙烯 (PP)、聚乙烯 (PE)、聚对苯二甲酸乙二醇酯 (PET)、聚对苯二甲酸丁二醇酯 (PBT)、聚酰胺 (PA)、聚对苯二甲酸丙二醇酯 (PTT) ,以及双组分PP/PE、PET/PE、PET/PP、PA6 /PP、PBT/PP、PTT/PP ,两种组分的比率为 2 5 /75、5 0 /5 0、75 /2 5。本文介绍了双组分熔喷非织造布的纤维结构与性能 ,还讨论了新型的并列型双组分熔喷非织造布的独特性能

Bi-Component Fiber Meltblown Nonwovens and Potential Applications

Meltblowing is a most versatile and cost effective process commercially available world wide to produce microfiber nonwovens in one step from thermoplastic resins. In recent few years there has been a growing interest in development of bicomponent (bico) meltblown nonwovens. Fundamental research has been done with Reicofil bicomponent (bico) meltblown line at TANDEC since its installation in March 1999. Various thermoplastic resins and their bico combinations were experimented, including mono polypropylene (PP), polyethylene (PE), polyethylene terephthalate (PET), polybutylenes terephthalate (PBT), polyamide (PA), polytrimethylene terephthalate (PTT), and bico PP/PE, PET/PE, PBT/PP, PA6/PP, PBT/PP, PTT/PP at bico ratios of 25/75, 50/50, and 75/25. In this paper, the fiber structures and properties of bico meltblown webs are presented. Unique properties and potential application of the novel side by side bicomponent meltblown fabrics are also discussed.
