  Abstract:In order to solve the problem of difficult production in the preparation process of fabric of hard-twist plied yarns with ZZ-twist and SS-twist，the performance and indexes of single yarn and plied yarn are introduced，and the technical difficulties and solutions in the warping and sizing process of CJ 7.3 tex ×2 hard-twist plied yarns with ZZ-twist and SS-twist are discussed.It is pointed out that hard-twist plied yarns with ZZ-twist and SS-twist is unstable in twist，and easy to produce kink and small braided yarn，which are the reasons why warping and sizing process can not be normal production.Before sizing process，appropriate process parameters should be selected to steam and twist the two kinds of yarns to reduce the internal stress of hard-twist plied yarn and improve the stability of twist.In warping process，measures should be taken to keep the uniform tension of the warp yarn.In sizing process，the appropriate sizing viscosity，single groove and single layer sizing method，and the optimization of tension setting in each area can reduce the snarling，winding and breaking of the two warp yarns.
Key Words:plied yarn；ZZ-twist；SS-twist；twist；small braided yarn；twist setting；warping；sizing；tension
