纤维素纤维:莱赛尔工艺 在莱赛尔生产工艺中保障纤维质量和产能提升 再生纤维素纤维(又称人造丝纤维)的制备方法是对木浆纤维素进行化学改性,并将其溶解于溶液中以制成细纤维。 常见的人造丝纤维有粘胶纤维、醋酸纤维和莱赛尔纤维。 莱赛尔得益于其光滑度和优异的湿强度而常用于工业应用。 如何生产莱赛尔? 莱赛尔是将木浆溶于 N-甲基吗啉 N-氧化物 (NMMO) 等有机溶剂中而制成。在该工艺中,溶液的浓度和温度发挥着重要作用,例如,如果含水量过高(超过 15%),纤维素将无法溶解。该溶液最初由 50-60% 的 NMMO 制备而成,然后在加热型溶解容器中蒸发以浓缩为 NMMO、水和纤维素的比例大约为 76:10:14 的原液。 原液经过滤后被送入干喷湿纺工艺流程,并在此流程中通过喷丝头挤出以形成长丝。之后,纤维经过洗涤、干燥和切割,制成最终的莱赛尔纤维。 维萨拉 K-PATENTS® 在线折光仪可以在莱赛尔生产工艺中连续监测原液和溶剂的浓度,从而提高生产效率、提升纤维品质。 阅读应用说明,详细了解莱赛尔生产工艺流程。 填写表格,即可下载 PDF 格式的应用说明。 返回所有化学品和同类产品应用 Email Address*First Name*Last Name*Country*--Please Select--United StatesUnited KingdomCanadaChinaIndiaJapanAustraliaBrazilFranceGermanyFinland--------------AfghanistanÅland IslandsAlbaniaAlgeriaAmerican SamoaAndorraAngolaAnguillaAntarcticaAntigua and BarbudaArgentinaArmeniaArubaAustraliaAustriaAzerbaijanBahamasBahrainBangladeshBarbadosBelarusBelgiumBelizeBeninBermudaBhutanBoliviaBosnia and HerzegovinaBotswanaBouvet IslandBrazilBrit/Indian Ocean Terr.Brunei DarussalamBulgariaBurkina FasoBurundiCambodiaCameroonCanadaCape VerdeCayman IslandsCentral African RepublicChadChileChinaChristmas IslandCocos (Keeling) IslandsColombiaComorosCongoCongo, The Dem.
