    Abstract: This application describes a method of preparation of a natural graphene cellulose blended fiber, which comprises using a graphite powder as a raw material for preparing a graphene solution, adding the graphene solution to a slurry formed by mixing and dissolving a wood pulp with N-methylmorpholine N-oxide (NMMO), removing the water content thereof to form a spinning dope, and then spinning the spinning dope by a Dry-Jet Wet method to manufacture a natural graphene cellulose blended fiber. The present method does not require a highly toxic hydrazine hydrate solution. Further, by increasing the adding ratio of the graphene solution in the manufacturing process, control of the antistatic properties and thermal transferring functions can be achieved, and thereby various requirements of different consumers can be satisfied. Besides, the fibers can decompose naturally after being used, and thus the product is harmless, natural, and environmentally friendly.

    Abstract: The present invention provides a processing method of natural cellulose fiber intrinsically with enhanced antiseptic, deodorant and negative-ion features 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, spin the dope obtained previously by dry-jet wet spinning method and coagulate and regenerate in a coagulation bath to form into threads. Finally, rinse, desiccate and lubricate the regenerated threads obtained previously as well as wind it up to produce reeled natural bamboo cellulose fiber with enhanced antiseptic, deodorant and negative-ion features.

    Abstract translation: 本发明提供了一种天然纤维素纤维的加工方法，其特征在于竹子具有增强的防腐，除臭和负离子特征。 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，通过干喷湿法旋转先前获得的涂料，并在凝固浴中凝结和再生成螺纹。 最后，冲洗，干燥并润滑先前获得的再生丝，并将其卷起来，生产具有增强的防腐，除臭和负离子特征的卷绕天然竹纤维素纤维。
