摘要： PURPOSE: A manufacturing method of cellulose fiber having excellent flexibility and strength is characterized by dissolving 0.01-3wt.% of cellulose powder into liquid concentrated N-methyl morpholine N-oxide(NMMO) to manufacture a NMMO solution, dissolving a small quantity of pulp into the liquid concentrated NMMO to lower melting point of the NMMO, being capable of supplying the NMMO solution to an extruder at lower temperature, having a wide process-temperature range and being capable of swelling the cellulose powder and the NMMO solution smoothly to prevent a film from being formed on a surface of the cellulose powder. CONSTITUTION: Cellulose fiber is obtained by the steps of: (A) dissolving 0.01-3wt.% of cellulose powder into liquid concentrated N-methyl morpholine N-oxide(NMMO) to manufacture a NMMO solution; (B) supplying the NMMO solution and the cellulose powder to an extruder installed a screw to manufacture a swollen and uniformed cellulose solution having dispersing property, mixing property, shearing property, kneading property, dissolving property and measuring property; (C) extrusion-spinning the cellulose solution into a spinning nozzle; passing the spun solution through an air area to reach a coagulating bath, followed by coagulating the solution to manufacture multi-filament; and then (D) washing, drying, oiling and winding the multi-filament.
摘要翻译：目的：具有优异的柔软性和强度的纤维素纤维的制造方法的特征在于将0.01-3重量％的纤维素粉末溶解在浓缩的N-甲基吗啉N-氧化物（NMMO）中以制备NMMO溶液，溶解少量纸浆进入液体浓缩NMMO以降低NMMO的熔点，能够在较低温度下将NMMO溶液供给到挤出机，具有宽的工艺温度范围，并且能够平滑地使纤维素粉末和NMMO溶液溶胀以防止在纤维素粉末的表面上形成膜。构成：通过以下步骤获得纤维素纤维：（A）将0.01-3重量％的纤维素粉末溶解在液体浓缩的N-甲基吗啉N-氧化物（NMMO）中以制备NMMO溶液; （B）将NMMO溶液和纤维素粉末供给到安装螺杆的挤出机中，制造具有分散性，混合性，剪切性，捏合性，溶解性和测量性的溶胀均匀的纤维素溶液; （C）将纤维素溶液挤出纺丝到纺丝喷嘴中; 将纺丝溶液通过空气区域到达凝固浴，然后使溶液凝固以制造复丝; 然后（D）洗涤，干燥，上油和缠绕复丝。

摘要： PURPOSE: Lyocell multi-filament is capable of producing tire cord having excellent physical properties. The tire cord has low elongation, increased strength, increased modulus, excellent drive stability, shape stability and uniformity. A manufacturing method thereof is characterized by increasing productivity. The lyocell multi-filament is useful for a tire for a passenger car. CONSTITUTION: Lyocell multi-filament is obtained by the steps of: (i) dissolving mixed powder of cellulose and PVA in a solvent mixed N-methyl morpholine N-oxide(NMMO) and water to prepare dope; (ii) spinning the dope through a spinning nozzle containing many orifices; passing fiber of the dope through air; coagulating the fiber into an upper part of a conic coagulating bath to manufacture multi-filament; (iii) change a course of the filament in a lower part of the coagulating bath; washing the filament in a washing bath; and then (iv) drying, oiling and winding the filament. The orifices has 100-300μm of diameter, 200-2400μm of length, 2-8times of the ratio of the diameter to the length, and 2.0-5.0mm of intervals between the orifices.
