investigation of the effects of pumice stone powder and polyacrylic ester based material on thermal insulation of polypropylene fabrics

Bu çalışmada polipropilen(PP) kumaşların ısı izolasyonu ve adhezyon özelliklerinin geliştirilmesi amaçlanmıştır. Çalışmada, tekstüre PP atkı iplikten, içi boş PP elyaftan elde edilmiş tekstüre atkı iplikten ve PP elyaftan elde edilmiş dokusuz yüzey kumaş olmak üzere üç farklı PP kumaş kullanılmış, her kumaşın ısı izolasyonu özelliklerini geliştirmek için kumaşların bir yüzü farklı konsantrasyonlarda ponza taşı tozu içeren poliüretan bazlı materyal ile kaplanmıştır. Ardından kumaşların diğer yüzeyleri kumaşlara adhezyon özellik kazandırmak amacı ile poliakrilik ester bazlı madde ile kaplanmıştır. Kumaşların ısı iletim katsayılarına kumaş türünün, ponza taşı konsantrasyonun ve poliakrilik ester bazlı yapının etkisi ayrıca poliakrilik ester bazlı yapının kumaşların adhezyon özelliklerine etkisi incelenmiştir. Sonuçlar ponza taşı konsantrasyonu artışının ve poliakrilik esterin kullanımının numunelerin ısı iletim katsayılarının azalmasına neden olduğunu göstermektedir. Ayrıca poliakrilik ester bazlı yapının kullanımı, kumaşlara her yüzeye karşı adhezyon özellik kazandırmıştır.

Polipropilen kumaşların ısı izolasyonu üzerine ponza taşı tozu ve poliakrilik ester etkisinin incelenmesi

This study has aimed at the development of thermal insulation and adhesion properties of polypropylene (PP) fabric. The texture PP weft yarn, the texture weft yarn produced from hollow PP fiber and the nonwoven produced from PP fiber were used as three different raw materials, each of which was one-side coated with the mixture containing polyurethane and pumice stone powder with different concentrations in order to improve thermal insulation properties. Then the other sides of these fabrics were coated with polyacrylic ester based material so as to improve adhesion behavior of the fabrics. Finally, heat transfer coefficients of each fabric were analyzed in accordance with fabric type, concentration of pumice stone powder and polyacrylic ester based material along with adhesion properties. The results demonstrated that the increase in the concentration of pumice stone powder and the use of polyacrylic ester based material caused the decrease in the thermal conductivity coefficients. In addition, the use of polyacrylic ester based material brought in adhesion properties to fabrics in order for the ability to adhere these fabrics onto any surface. Key Words: Adhesion, Coating, Thermal insulation, Pumice stone, Polypropylene. ÖZET
