| Abstract | ||||
| This paper includes firstly a theoretical study of the combined effect of dimensionless fabric construction factors such as thread diameter, thread spacing, thread displacement from fabric centre, degree of thread flattening and float ratio on crlap interchange between warp and weft threads. The obtained relations determines accurately the crimp percent for both warp and weft under any presumed construction, the mathematical relations between warp and weft wrap angles due to change of float ratio were also determined through the corrospondant change of the relative thread displacement from fabric centre based on fabric force analysis. This previous relation paved the way to correlate mathematically the relation between the float ratio and crimp percent in both IP and weft under different thread spacing which showed that the change in thread spacing has insignificant effect on the relation between float ratio and relative thread displacement . The study included secondly an experimental measurement of warp variation for simple plain weave and weft rib weave woven taneously on the same projectile weaving machine side by side was possible to change the weft float and mentain the same Feeding rate. The results shoved a very good encouraging agreement between an experimental and theoretical results, the experimental measurement Included the warp tension variation within and between heald during the normal weaving process. | ||||
