Abstract: On the basis of trial2producing downPkapok battings , the compressive and warmth retention
properties of these battings are investigated in this paper. It′s showed that the usage of chemical fibers , such
as fine2denier PET fibers , etc , could effectively improve the compressive resilience of battings. When kapok
replaced down or down waste in the battings , the compressive resilience of battings would reduce slightly ,
however , it wasn′t distinct when the content was changed slightly. The usage of down could improve the
warmth retention of battings , and kapok was less important than down in improving the warmth retention of
battings , but more useful than other chemical fibers (PP , PET , etc) . Down waste could reduce the warmth
retention of battings , but not remarkable.
