Coating of fibers, yarns and textiles with metals has become an important issue in textile industry. These fabrics use in condutive textiles, smart textiles, collection water from fog and many زمینه های دیگر.In this study polypropylene fabrics were coated using electroless, printing and thermal spray methods. Electroless coating was performed by two different weight percentages of metal and Printing of fabrics was coated using three samples with different amount of metal. SEM images and Optical microscopic images were used to surface of the samples and cross section of the fabrics. Also were done EDX analysis, Mechanical properties includes tensile strength and tear resistance, thermal conductivity, electrical conductivity, washing fastness, wettability, air permeability and the amount of the water collected from simulated foggy air. EDX analysis revealed existence of 41%w/w of Cu on the sample surface. For all of the samples, coating reduced the tensile strength, although by increasing the amount of the metal, the reducing of tensile strength was lessen in comparison untreated sample. The sample which was printed with 12 gr/kg Cu in printing paste, showed significant reduction in the tear resistance in comparison to the untreated sample. Thermal conductivity of the elecroless deposited sample wsa more than the all of the other samples and thermal conductivity coefficient of the elecroless deposited sample was six-fold more than the untreated sample. electrical conductivity of the electroless deposited sample increased 10 7 times in comparison with the untreated sample. Surface wettability was reduced for all of the coated samples. Washing fastness of the electroless deposited sample was more than the other two methods. Reducing in the air permeability of the electroless deposited sample was lessen than the other two methods. Amount of the collected water from fog was six-fold for the Electroless deposited sample in comparison with the untreated sample.
