摘要
为了探究海藻酸钙纤维的掺入对芳纶/海藻非织造布阻燃、热防护等性能的影响,以无污染的混合方法制备了芳纶/海藻非织造布并对其性能进行了试验分析。结果表明:海藻纤维的掺入极大延长了点火时间,并抑制了芳纶的烟气释放。海藻酸钙纤维不仅有效改善了芳纶在450℃高温下的燃烧性能,留下更多的残余物进行热隔离,更改善了织物的阻燃性能。海藻纤维对提高芳纶/海藻非织造布的阻燃性能具有积极作用。
In order to investigate the effects of calcium alginate fiber on the flame retardant and thermal protection properties of aramid/seaweed nonwovens, the aramid/seaweed nonwovens are prepared by a green and pollution-free hybrid method. The properties of aramid/seaweed nonwovens are experimentally analyzed. The results show that the addition of seaweed fiber greatly prolongs the ignition time and restrains the smoke release of aramid fiber. Calcium alginate fiber not only effectively improves the combustion performance of aramid fiber at 450 ℃, but also improves the flame retardant performance of the fabric by leaving more residue for thermal isolation. Seaweed fiber plays a positive role in improving the flame retardancy of aramid/seaweed nonwovens.
