Abstract: Abstract In order to realized the rapid design of the thinnest multibar Raschel lace, the design method of the thinnest multibar Raschel lace is studied, and the jacquard design principal of the thinnest multibar Raschel lace is concluded. The corresponding relationship between the lapping effect and jacquard pattern grid is explored. A CAD system is developed to design of the multibar Raschel lace especially, and realized the quick design of the thinnest multibar Raschel lace by using two kind of colour design the jacquard pattern grid. The factors that affect the loop migration in the fabric is analysed, the simulation method that suit for the thinnest multibar Raschel lace is explored, using VC + +.net for programming tools realized the simulation of the thinnest multibar Raschel lcae.
