Research on extraction technology and stability of natural anti-moth finishing agent extracted from plant.

The paper studied the thermal stability, pH stability and placed time stability of natural anti-moth finishing agent named KC-CT. Further, the effect of extracting temperature, time, material to liquor ratio, times on extraction technology were discussed by changing the parameters, and the optimal extracting process had been determined through orthogonal test. The anti-moth property of finished on wool fabric was tested by the standard FZ/T 20004-1991. The results showed that: KC-CT's thermal stability and placed time stability were very good; KC-CT was stable at pH value 4 ∼8 and relatively unstable when its pH value at 9 ∼ 10. The optimum extraction conditions for KC-CT was 100°C , 90 min, 1:20 and 2 times. Wool fabrics finished with KC-CT had got the anti-moth property at 1A level. Anti-moth property was qualified by Chinese standard. [ABSTRACT FROM AUTHOR]
