Abstract
The present invention relates to, and more particularily, to a lyocell dip cord and tire produced by a method comprising the steps of: (A) dissolving 0.01 to 3 wt % of cellulose powder in portions in concentrated liquid N-methylmorpholine N-oxide (NMMO) to prepare cellulose-containing NMMO solution; (B) feeding the NMMO solution and cellulose powder into an extruder having a screw to be subjected to dispersing, mixing, shearing, kneading, melting and measuring ability in the extruder to prepare a swollen and homogenized cellulose solution; (C) spinning the cellulose solution through a spinning nozzle, passing the spinning solution through an air gap to a coagulation bath and coagulating the spinning solution to obtain a multifilament; (D) subject the multifilament to water-wash, drying and oil-treatment, followed by winding; and (E) twisting the wound yarn with a twisting machine to prepare a greige cord, weaving the greige cord and dipping the woven cord in a dipping solution.
