Effect of zinc chloride reagents from different manufacturers on dissolution conditions of Lyocell/cotton blended fabric
When analyzing a Lyocell and cotton blend sample using formic acid/zinc chloride solution,the main influencing factors are reagent temperature and dissolution time.Under the condition of dissolution temperature of 70,the research on the influencing factors such as the zinc chloride reagent,pretreatment,and sample amount showed that the dissolution capacity of Lyocell fibers in formic acid/zinc chloride solution prepared by zinc chloride reagents from different manufacturers varies,and the corresponding d value of cotton fibers is also different.Therefore,it is necessary to separately determine the dissolution time and the corresponding d value of cotton fibers.
