Abstract: The application of traditional kapok wadding is limited to a narrow scope due to its weakness of intensity,duration of compression and recovery,so a patented technology to improve its performance was developed.In this paper, we tested the compressibility of kapok wadding produced with traditional method and that by patented technology,and analyzed the differences between new types of kapok wadding mixed with different chemical fibers.The results indicated that the resilience of kapok wadding containing chemical fibers is obviously improved though its initial bulkiness is smaller than that of pure chemical wadding and pliability is not comparable to that of pure kapok wadding.
