Abstract:

One of the most common procedures for exporting and warehousing handmade carpets is keeping them folded over one another. Handmade carpets come out of their stable states by being folded,while increasing storage time can cause serious and sometimes irreversible changes to them. In this research, a pilot model carpet has kept folded under a load equal to 50 g/cm2 and then the applied load increased respectively to 100, 200, 500, 1000 g/cm2 continuously and uniformly, and at every stage the digital image of the form of folded carpet has been recorded. The received image was analyzed by software programs to identify and determine the morphology of folding curvature of handmade carpet under static pressure. It is possible to propose convenient predictions for storage and packing of carpets, considering the morphology of folding curvature of handmade carpet during successive loading and unloading phases. Accordingly,is this research it was determined that the empty space in folding curvature of handmade carpet after removing the pressure and returning to the first state isalmost 9 times less than the same for the first time the carpet was folded. This research also showed that if the setting height of stored carpets, which are folded over each other, does not change then the damage is much less comparing the time that carpets’ height decreases constantly and forcesapplied to carpets change. Moreover, possibility of carpets falling due to loss of instability of folding curvature length at loading time is much greater than during unloading time. Also in this research, folding curvature height, folding curvature length and empty space in folding curvature were studied and measured.

بررسی تا‌خوردگی فرش دست‌باف تحت فشار استاتیکی

To study the way of folding handmade carpets, the selected sample has been put under pressure of 50g/cm2 weight at three different states. The pressure has increased uniformly and continuously at 100,200, 500, 1000 and 1500 g/cm2. The thickness of the carpet has been recorded continuously during the measurement of the thickness of the carpet sample. The pressing parameters of the carpet have be...

تحلیل رفتار فشار پذیری خاب فرش دستباف

The existing standards for measuring carpet properties consider carpet behavior after loading while its dynamic and instantaneous behavior is neglected. To investigate the dynamic behavior of under loading carpets, an INSTRON machine equipped with a developed system was used. The reliability of the system was verified by testing different materials. Different samples of hand-knitted carpet with...
