Abstract


Pada saat ini pengembangan produk tekstil fungsional cukup pesat, salah satunya adalah produk tekstil fungsional yang memiliki sifat thermo-regulating. Untuk maksud tersebut, pada penelitian ini telah dilakukan penerapan phase change material (PCM) yang berbasis polietilena glikol (PEG) pada kain campuran poliester/cationic dyeable polyester (CDP) dan campuran poliester/rayon (T/R) dengan cara pad-dry-cure. Formula PCM yang digunakan merupakan campuran PEG (berat molekul 1000) 5%/ N-metiloldihidroksietilenurea (N-MDHEU) 3%/ katalis MgCl2 0,3 % dalam suasana asam. Karakterisasi dan pengujan kain hasil percobaan dilakukan dengan menggunakan fourier transform infrared (FTIR), scanning electron microscope (SEM) dan differential scanning calorimeter (DSC). Hasil penelitian menunjukkan bahwa kain poliester/CDP yang diberi perlakuan memiliki aktivitas termal dengan nilai T(m)= 36,95°C, ΔHf = 4,98 J/g dan T(c)= 20,06°C, ΔHc = 5,30 J/g, sedangkan kain T/R yang juga diberi perlakuan mempunyai aktivitas termal dengan nilai T(m)= 34,56°C, ΔHf = 0,079 J/g, dan T(c)= 19,49°C, ΔHc = 0,024 J/g. Hasil uji pencucian terhadap kain hasil percobaan menunjukkan hasil yang belum optimal, dimana pada uji pencucian yang setara dengan 1 kali pencucian rumah tangga menunjukkan PCM masih terdegradasi dari permukaan kain.
