    摘要： The present invention provides a processing method of non-woven intrinsically with enhanced deodorant feature from bamboo. The process uses mixture of wasted coffee residue and bamboo pulp as raw material. The process uses N-methylmorpholine N-oxide (NMMO) as primary solvent and 1, 3-phenylene-bis 2-oxazoline (BOX) as additive stabilizer. A cellulose solution is firstly formed by the wasted coffee residue, bamboo pulp, NMMO and BOX aforesaid. Secondly, via grinding, blending, dissolving and thermal dehydrating, the cellulose solution is converted into spinning dope. Thirdly, via meltblown method, the dope is extruded out of spinnerets in a die assembly by a metering gear pump to form thread bundle. Finally, the thread bundle is orderly treated by coagulation with regeneration via ejecting mist aerosol of water, rinsing, bleaching, re-rinsing, drying, winding-up and the like to create continuous filaments, then final product for nonwoven with deodorant feature is produced by the filaments from bamboo cellulose.

    摘要翻译： 本发明提供了一种无纺布本身具有竹子增强除臭特征的加工方法。 该方法将废咖啡残渣和竹浆混合物作为原料。 该方法使用N-甲基吗啉N-氧化物（NMMO）作为主要溶剂，1,3-亚苯基 - 双2-恶唑啉（BOX）作为添加剂稳定剂。 纤维素溶液首先由废咖啡残渣，竹浆，NMMO和BOX形成。 其次，通过研磨，混合，溶解和热脱水，将纤维素溶液转化为纺丝原液。 第三，通过熔喷方法，通过计量齿轮泵将涂料从模具组件中的喷丝头挤出以形成螺纹束。 最后，通过用喷雾雾化的水，漂洗，漂白，再漂洗，干燥，卷绕等进行再生，通过凝结有序地处理线束，从而产生连续的长丝，然后产生用于具有除臭特征的非织造布的最终产品 由竹纤维素的丝。

    摘要： The present invention concerns a method for the recovery of solvent in a process for preparation of regenerated cellulosic fibers using sodium hydroxide as solvent for cellulose dissolving in the manufacturing of a cellulose spinning dope wherein sodium hydroxide present in the spinning dope is at least partially recovered and recycled as sodium hydroxide from a cellulose fiber regeneration or cellulose coagulation step and wherein said cellulose fiber regeneration or cellulose coagulation step consists of a bath into which cellulose spinning dope is injected. Recovered sodium hydroxide may be directly or indirectly recycled from a cellulose fiber regeneration or cellulose coagulation step to a cellulose dissolving step.
