摘　　要：生物酶——纤维素酶和漆酶对木棉纤维进行预处理,研究生物酶的温度和时间对木棉纤维的微观结构、结晶度、热重等性质及染色性能的影响。结果表明:生物酶处理后,纤维的微观结构变化较小,结晶度基本没有变化,热降解温度降低了10℃左右。漆酶处理后木棉的吸湿率由10.08%增加到12.50%左右,较小浓度的纤维素酶处理木棉纤维后,木棉的吸湿率也增加到13%左右,浓度较大后,木棉纤维的吸湿率为11%。未处理的木棉靛蓝染色,K/S值在4.5左右;酶处理后木棉纤维的K/S值均在6以上,因此生物酶处理后木棉纤维的上染率均增大。漆酶处理后木棉纤维上染率明显增加,说明木质素阻碍染液进入纤维。Using enzymes-cellulase and laccase treating kapok fiber pretreatment, studied the effect of temperature and time of the enzymes on microstructure, crystallinity, thermal and other properties and dyeing properties of kapok fiber. The results were as follows： after treated, the microstructure of the kapok fibers changed very little, and the crystallinity did not change substantially, the thermal degradation temperature reducing about 10 degrees. After the laccase treated, the absorbent rate rised from 10.08% to 12.50%; after small concentration of cellulase treated, the absorption rate also increased to about 13%, but when greater concentration, absorption rate was just 11%. The untreated kapok fiber＇s K/S values was about 4.5; the kapok fiber＇s K/S values after the enzyme treated was six or more, so the enzyme treated kapok fiber＇s dyeing rate increased. The dye-uptake of kapok fiber increasing significantly after eilzyme treatment indicated that lignin hindered the dye liquor into the fiber.
