涤黏氨混合产品不同定量方法效果分析

Effect Analysis of Different Quantitative Methods for Polyester Viscose Ammonia Mixed Products

为了筛选出最优的涤黏氨混合产品定量方法,设计6种定量方案分别进行测试。然后用核查样品对优选的方案进行复现性测试,并用t检验对测试数据进行分析。结果表明,涤黏氨混合产品宜采用物理、化学相结合的定量方案,即先采用物理法拆分氨纶,再用75.0%硫酸溶解黏胶纤维的定量方法,定量结果数据稳定。

In order to screen out the optimal quantitative method for polyester viscose ammonia mixed products,six quantitative methods were designed and tested respectively. Then, the recurrence test of the preferred scheme was carried out with verified samples, and the test data were analyzed with T test. It is concluded that the quantitative scheme of physical and chemical combination should be adopted for the polyester viscose ammonia mixture product,that is, the quantitative method of physical separation of spandex and dissolution of viscose fiber with 75.0% sulfuric acid was adopted, and the quantitative data was stable.
