Abstract:

Aiming at the problem of difficulty in setting the let-off value when the technology of double-bed single-jacquard fabrics is changed, the experiments were completed with 166.67 dtex and 33.33dtex polyester on warp dnitted machine, and the relationship between the number of three different meshes and the let-off was tested when the density was tested when the density was 15 course/cm. The change trendency and differences of the let-off of three different mesh were got bycomparing and analyzing the experimental data through the methods of the let-off and has different degree of influence on the three different types of meshes. The number of the mesh increases by 2 coils, and the let-off reduce by 12-23 mm/rack.

Key words: double-bed, single facquard, mesh, let-off value
