With oleic acid grafting modification, a series of hyperbranched-linear polymer surfactants (HLPS) were prepared by hydroxyl-terminated hyperbranched polymer (HBP), which was gained through a step synthesis method using trimethylolpropane and AB2 monomer. The AB2 monomers were obtained through the Michael addition reaction of methyl acrylate and diethanol(More)
DT-F203 fatliquor is a kind of oxidized sulfiting vegetable oil fatliquor. Taking DT-F203 fatliquor for example, the biodegradability of oxidized sulfiting vegetable oil fatliquor was studied. The methods of BOD<sub>5</sub>/COD<sub>Cr</sub>, respiratory curve and COD<sub>30</sub> were adopted to evaluate the biodegradability of DT-F203 fatliquor for the(More)
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(More)
