Beschreibung
Zusammenfassung:	The invention discloses a self-discoloring method of a polyimide non-woven fabric, comprising the following steps: fabric-treatment-drying-color measurement; the treatment is carried out according tothe following treatment formula and conditions: 5-7 g/L of sodium carbonate, 10 to 30 g/L of sodium hydrosulfite, the treatment time is 10 min to 15 min, and the treatment temperature is 80 DEG C to 90 DEG C.The polyimide non-woven fabric is used, and is subjected to reduction treatment under an alkaline condition, the color is changed into light green from golden yellow, the light green is fixed,and no oxidation is generated in the air.With the increase of the dosage of a reducing agent, the green is deepened.By using the method provided by the invention, polyimide can change into green without dye, and can be used for producing finished products such as discoloring clothes, toys and home textiles. 本发明公开了一种聚酰亚胺无纺布的自变色方法，包括如下步骤：面料→处理→烘干→测色；其中，所述的处理：处理配方和条件如下：纯碱：5-7g/L；保险粉：10-30g/L；处理时间为：10min-15min；处理温度为：80℃-90℃。本
