Abstract:In order to ensure the sizing quality of cotton/polylactic acid fiber blended fabrics，the characteristics of polylactic acid fiber，cotton/polylactic acid fiber blended fabric specifications and technical conditions are introduced.By comparing the properties of polylactic acid fiber and cotton fiber，the technical difficulties of sizing process of cotton/polylactic acid blended fabric are summarized.The optimization of sizing process，sizing quality and weaving effect are described in detail from the aspects of sizing agent selection，sizing agent  formula determination and sizing process control.It is pointed out that reasonable sizing agent  formula，proper soaking and coating are the key to improve the weavability of the sized yarn，and the sizing agent  should be selected according to fiber characteristics，yarn density，variety structure，sizing process，etc.According to the principle of “similarity and intermiscibility”，the sizing agent  formula based on denatured starch and polymeric sizing agent  with good adhesion and film forming properties and “two high and one low” sizing process，reasonable control of sizing rate and moisture recovery rate，and post-waxing process can achieve the goal of sticking hairiness on cotton/polylactic acid blended yarn after sizing，enhancing wear resistance and improving the weavability of the sized yarn.Loom opening clarity，cloth machine efficiency and cloth surface quality are also improved.
Key Words:polylactic acid fiber；polyester fiber；cotton fiber；blended yarn；sizing agent；sizing；hairiness；similarity and intermiscibility；two high and one low
