Evaluation of Heat Setting Parameters in Carpet Comfort

摘要

In this paper, carpet comfort has been evaluated from the subjective and objective point of views in relation to the pin-point effect of pile yarns of carpets. For doing judgment on the carpet comfort before weaving the carpets, bundle comparison method has been suggested and a standard method has been presented for the bundle preparation. This research focused to find the best pile yarns twist and heat set conditions to obtain optimum condition for heat set carpets. To achieve the objectives of this research, yarns of different twist were heat set at various times and temperatures. Taguchi method has been used as the method for the design of the experiments, then the effect of the controllable factors of heat setting process in the comfort of carpets has been investigated. Observers did test the both comfort and aesthetic of yam bundles and both compression modulus and expenditure energy have been calculated as the subjective and objective methods, respectively. Objective evaluation has been done based on the earlier researches results that defined more carpet comfort could be achieved in pile samples with lower compression modulus. Consequently, the optimum heat setting parameters have been achieved by an outlook on Taguchi results and constraint analyses by response surface methodology.
