Abstract:

 In this study, it was aimed to develop fabrics that can convert sunlight into heat energy and have improved thermoregulation properties. For this purpose, n-tetradecanolgum arabiccopper IIoxide TDAZCuO wall structured microcapsules were applied to cotton fabric by impregnation method. The morphological, thermal properties, and photothermal conversion performance of fabrics applied with microcapsules at two different concentrations of 100 gl and 150 gl were investigated. In addition, the effect of capsule application on the thermophysiological comfort parameters and mechanical properties of the fabric was investigated. Scanning electron microscope images revealed the presence of microcapsules in the fabric structure. According to the results of differential scanning calorimetry DSC analysis, the fabrics had a heat storage capacity of 3.78 jg at 28 C. These fabrics exhibited photothermal conversion performance, converting UV light into heat energy and reaching temperatures 6 C higher than untreated fabric in the same period. Alambeta test results showed that CuO nanoparticles in the wall structure of the microcapsules significantly increased the thermal conductivity of the fabric. In addition, microcapsule application didnt significantly affect the tear strength of the fabric in weft and warp directions. On the other hand, capsule application caused a significant decrease in the air permeability values of the fabrics.

 Bu çalışmada, güneş ışığını ısı enerjisine dönüştürebilen ve gelişmiş termoregülasyon özelliğine sahip kumaşların geliştirilmesi amaçlanmıştır. Bu amaç doğrultusunda n-tetradekanolarap zamkıbakırII oksit TDAZCuO duvar yapılı mikrokapsüller pamuklu kumaşa emdirme yöntemi ile uygulanmıştır. 100 gl ve 150 gl olmak üzere iki farklı konsantrasyonda mikrokapsül uygulanan kumaşların morfolojik, ısıl özellikleri ve fototermal dönüşüm performansları araştırılmıştır. Bu analizlere ek olarak kapsül uygulamasının kumaşın termofizyolojik konfor parametrelerine ve mekanik özeliklerine etkisi araştırılmıştır. Taramalı elektron mikroskop görüntüleri, mikrokapsüllerin kumaş yapısındaki varlığını ortaya koymuştur. Diferansiyel taramalı kalorimetre DSC analiz sonuçlarına göre kumaşlar 28 Cde 3,78 Jg ısı depolama kapasitesine sahiptirler. Söz konusu kumaşlar fototermal dönüşüm performansı sergileyerek UV ışığını ısı enerjisine dönüştürmüş ve aynı süre içinde ham kumaştan 6 C daha yüksek sıcaklıklara ulaşmıştır. Alambeta test sonuçları, mikrokapsüllerin duvar yapısında bulunan CuO nanopartiküllerinin kumaşın ısıl iletkenliğini önemli ölçüde artırdığını göstermektedir. Ayrıca, mikrokapsül uygulaması kumaşın atkı ve çözgü yönlerindeki yırtılma mukavemetini anlamlı bir şekilde etkilememiştir. Öte yandan, kapsül uygulaması kumaşların hava geçirgenlik değerlerinde önemli düşüşe neden olmuştur.
