Preparation and sizing properties of dodecylated starch size
In order to improve the shortcomings of brittle and hard corn starch slurry.the corn starch was oxidized and etherified with bromododecane under alkaline conditions to prepare do-decylated starch slurry with excellent toughness.Infrared spectroscopy was used to characterize the prepared dodecylated starch slurry.and the performance indexes of slurry and slurry film were tested.The sizing properties of 14.6 tex cotton yarn were sipped with a slurry formulation contai-ning dodecylated starch and phosphate starch.respectively.The results show that the alkyl chain was successfully introduced into the starch structure to obtain a dodecylated starch slurry.The dodecylated starch slurry forms a film,the film is soft,and the adhesion to cotton fiber is good;By using dodecylated starch sizing.the hairiness reduction rate and yarn reinforcement rate of yarn were better than those of phosphate starch sizing.
