Abstract
Modified by the pretreated model with collagen under the crosslinking effect of glutaraldehyde, the moisture absorption of modified samples increased by 26.34% and 42.6%. The test results of SEM, AFM and DSC show that there was coating on the fibers modified with collagen, and the relative average roughness of the modified fabric decreased. Modification with collagen also affected the thermal properties of the modified sample compared with that of the non-treated sample. Modification of the base with collagen in the same way that modified the model, the result indicate that the contents of amino group on the modified base sample were 1.61 times and 8.15 times compared with that of pretreated sample and non-treated sample, water vapor permeability of collagen modified samples increased by 28.58% and 53.43% respectively.
