Study of Property Change of Solvent Spinning Rayon treated with Solvent and it's Approach to Utility

自从有机溶剂旋转纤维的纤维变得容易，当它被湿了，并被提交给一个机械动作，表面治疗已经被运送出去，以防止纤维的发生。一种铁钠焦油复合溶液（FeTNa）被用作细胞溶解剂和研究适当治疗条件、行为和消费特性。使用FeTNa复合体解决方案的TENCEL Yarn治疗导致了细胞主链的显著退化，但增加了晶体管。结晶性增加是一个非常重要的因素，可以归因于在一个反常区域中通过用复杂解决方案捕获细胞分子的相互作用。Swollen微端口结构的TENCEL纱线是由反向液体色谱法确定的。使用FeTNa解决方案的纱线治疗结果，以生产一种温度敏感的硬燕子凝胶与较小的微孢子大小，但与原始样本比较较大的总孢子体积。Formation of colloidal particles of Fe（OH）イイD23イエD2 on the surface of the treated yarns suggests the existence of the large voids running along the fiber axis。未加工纤维在均衡纤维中的提升略高于被加工纤维的水平。治疗后纤维的死亡率比未治疗纤维的死亡率要快34 - 38次。老化率的增加可以归因于纤维表面在潮湿条件下存在的空隙。Tencel Yarn的治疗与FeTNA解决方案在Crimpy纤维结构中的结果纤维的裂缝对纱线和编织结构的弹性恢复的巨大贡献。在被治疗的纱线中编织的织物在运动传输特性中很好。

Since fibrillation of organic solvent spinning fiber takes easily when it is wetted and subjected to a mechanical action, surface treatments have been carried out in purpose to prevent of the fibrillation. A ferric sodium tartrate complex solution (FeTNa) is employed as the cellulose solvent and investigated the appropriate treatment condition, swelling behavior and consumption properties. Treatment of TENCEL yarn with FeTNa complex solution causes no remarkable degradation of cellulose main chains but increase of crystallinity. Crystallinity increase is attributable to the rearrangements of intermolecular hydrogen bonds in an amorphous region through the swelling of cellulose molecules with the complex solution. Swollen micro-pore structure of TENCEL yarns are determined by the inverse liquid chromatography. The treatment of yarns with FeTNa solution results in producing a temperature insensitive hard swollen gel with smaller micro-pore sizes but larger the total pore volume in comparison with the original sample. Formation of colloidal particles of Fe(OH)ィイD23ィエD2 on the surface of the treated yarns suggests the existence of the large voids running along the fiber axis. The uptake of untreated fiber at equilibrium is slightly higher than that of the treated fiber. The dyeing rate of the treated fibers are 34〜38 times faster than that of the untreated fiber. The increase of dyeing rate is attributable to the existence of voids on the fiber surface under the wetting condition. The treatment of the TENCEL yarn with FeTNa solution results in the crimpy fiber structure. The crimps of fiber make large contributions to the elastic recoveries of yarn and knit fabric. The fabric knitted in the treated yarn is excellent in moisture transmission property.
