The results showed that the amorphous iron oxide has highly catalytic activity. The intermediate products are pyrocatechin, hydroquinone, benzoquinone and low-grade fatty acid. The mechanism of catalyst oxidation is assumed that the free radical OH attacks benzene cycle at the adjacent position and para-position of OH on phenol so that the benzene cycle is opened and low-grade fatty acid is produced and transformed into CO2 and H2O.

结果表明，非晶铁氧化物催化剂在催化氧化降解苯酚时具有较高的催化活性，苯酚降解的中间产物有：对苯二酚、邻苯二酚、苯醌和低级脂肪酸，其降解机理是羟基自由基攻击苯环上OH的部位或对位而使苯环开环，生成低级脂肪酸，并最终转化成二氧化碳和水，从而使苯酚得以降解。

In the production processes, the materials were arranged reasonably and the treating after the fiber dying was paid some attentions. It used the "light weight, low speed, large ratch, more carding and small dropping" principle in the carding process, and the "tight ratch, light weight, low speed" principle in the drawing and roving processes. The break ratch was let out properly in the spinning process.
