Abstract:In order to improve the weaving efficiency of light cotton/lyocell interwoven plain weave fabric，a down-proof fabric with a width of 308.5 cm is designed by using C 5.83 tex warp yarn，lyocell 6.56 tex weft yarn，warp density of 787.5/(10 cm) and weft density of 649.5/(10 cm)，according to the specifications and weaving difficulty coefficient of anti-boring plain weave fabric，and combined with the quality index of self-produced yarn.The problems in weaving process are analyzed，such as fabric tightness is high，warp yarn breaks easily，and weft cloth-fell rollbacks.The technical difficulties and key points of warping，sizing，reed and weaving process are analyzed.The results show that after controlling warping speed，tension and winding as even，adopting warp sizing idea of“double dipping，double pressure，double size boxes，high pressure，high consistency and low viscosity”and biaxial weaving technology of “small tension，large shuttle，high back beam and early weft insertion”，the loom efficiency can reach 83% at 510 r/min when the ratio of woven cotton to lyocell is 52∶48，gram weight of grey cloth is 91.7 g/m2 and the weaving difficulty coefficient is 36.7.
