聚氨酯弹性(氨纶)纤维生产工艺 氨纶纤维生产中的纤维浴液浓度控制 氨纶是由聚合物长链构成的合成纤维。此类纤维的常见商品名称包括 LYCRA (DuPont)、DORLOSTAN (Bayer)、SPANZELLE (Acordis) 和 VYRENE (US Rubber)。 通常,氨纶纤维结构是通过双异氰酸酯与长链二醇(如聚酯或聚醚)反应来实现的。接下来,聚合物会溶解在二甲基乙酰胺 (DMAC) 中,然后使用乙二醇、二胺或水进行扩链或偶联。也可以添加二甲基甲酰胺 (DMF)、硝酸 (HNO3) 等溶剂。最后的聚合物通过纺丝工艺转化为纤维。 维萨拉 K-PATENTS® 原位在线折光仪可控制纺丝浴液浓度。当浴液浓度达到最佳时,最终产品质量将维持较高水平。 阅读应用说明,详细了解聚氨酯弹性纤维生产工艺。 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.
