The invention relates to a preparation method of
starch-grafted composite glutin
sizing, and belongs to the technical field of
textile materials. By adding hydrogenated sheep oil and hydrogenated
castor oil, composite
sizing is prepared, and hydrogenated sheep oil and hydrogenated
castor oil have emulsifying properties under the action of tridecanol
polyoxyethylene ether and
monoglyceride, can beevenly mixed in the
sizing, play roles in plasticizing and improve the sizing percentage of the sizing. When
grease is added in an
adhesive containing polar groups,
grease molecules can destroy physical crosslinking points of
adhesive macromolecules and make it impossible for the polar groups of the macromolecules to establish interaction and
hydrogen bonds, original non-moving chain segments begin to move, the
vitrification temperature of serosas is reduced, and the serosas become softer. Besides, intervals between
grease molecules make cohesive force between
adhesive molecules reduced, a serosa structure thus relaxes, the strength is reduced, meanwhile the adhesive molecules are kept from fully moving close to
fiber due to isolation of the grease molecules, and the
desizing percentage ofthe sizing can be effectively improved.
