求翻译：在试验温度为90℃*60min时，本文首先运用单一变量原则，研究了几个重要因素对纯棉坯布前处理后织物白度的影响、依次测出了5min、30min、60min、溶液中过氧化氢浓度的变化，找出此三个阶段最适宜的过氧化氢浓度值，为后续试验的进行做好了铺垫，随后通过五组分重心设计法，进一步确定每个组分对过氧化氢的影响，对纯棉坯布的影响，比较得出一个较好的助剂配方，能够更好的应用于短流程中。是什么意思？

Test temperature is 90 ℃ * 60min, the paper first to use the principle of a single variable, the impact of several important factors before the cotton fabric treated fabric whiteness, followed by measured 5min, 30min, 60min peroxide solution changes in the concentration of hydrogen, to identify the
