Compressibility and thickness recovery characteristics of carpets

As indispensable home decoration textile materials, carpets should have high durability during usage. One of the performance tests that affect the usage life of the carpets are thickness recovery after static and dynamic loading. This paper deals with the structural properties, compressibility and thickness recovery properties of seven carpets produced from wool, acyclic, polypropylene fibers. The effects of raw material, yarn linear density, the number of loop per unit area were searched. It was found that, the increased yarn linear density and loop density affects thickness, pile mass and the recovery characteristics of the carpets positively. Wool carpets have higher pile mass than PAC carpets, and also due to the higher fiber density they have higher compressibility and recovery after dynamic loading and unloading. Thickness loss values of wool carpets are generally lower after long term static loading. The resistance to dynamic compression is higher for the carpets, which have higher number of loops per unit area and therefore recovery properties are better
