Abstract: In the present study, the theoretical analysis of the output of the models of the 1×1 rib loop formation process has been performed to get the insight into the mechanics of loop formation system. For the purpose, the important output variables of the models have been generated for 128 sets of combinations of input variable. The range of the values of input variables have been chosen keeping in view the machine and yarn parameters available for the earlier experimental work as well as relevant information available in published literature. The analyses of the output of the models reveal that the main output variables of the loop formation system, namely loop length and yarn tension (needle force), are influenced by different machine, yarn and process variables as well as timing of knitting. In some cases the response of the system, i.e. the change in output variables due to incremental changes in input variables is large, whereas in some other cases the response is moderate to marginal. In fact, the rate of change in output variables depends on the combination of the input variables as well as the range of values of input variables.
