The main topic of this project is investigation of the effects of warp's strand number on the tension reduction of Nain's handmade carpet. Cotton wrap yarn have special importance in handmade carpet, because warps of handmade carpet experiences different loads during knotting and weaving; therefore, the increase in warp stability lead to higher stability of carpet dimensions and longer life. In the current project, we measure the effect of strand numbers on the tension reduction of warps in

Here, we used researcher-made device for measuring warp tension outside of the loom, then readings and data was collected for future analysis of the effect of number of strands on the tension reduction and mechanical characteristics like tension reduction.
