Efek Modifikasi Plasma Untuk Meningkatkan Sifat Tahan Api Dari Kain Katunfect of Plasma Modification for Improving Fire Retardant Properties of Cotton Fabric

Abstract

Pada penelitian ini telah dikembangkan sifat tahan api pada bahan tekstil kain katun dengan menggunakan resin tahan api dan ekstrak daun bayam. Zat tahan api diaplikasikan pada kain katun dengan menggunakan metode plasma bertekanan atmosfir dan pad-dry-cure. Kain katun yang digunakan merupakan kain kapas yang telah mengalami proses pengelantangan dan merserisasi. Pada penelitian ini telah dilakukan tiga jenis metode, yaitu metode pad-dry-cure pada zat resin tahan api dengan pra-perlakuan plasma bertekanan atmosfer, metode perendaman pada zat resin tahan api dengan pra-perlakuan plasma bertekanan atmosfer, dan metode perendaman pada ekstrak daun bayam dengan pra-perlakuan plasma bertekanan atmosfer. Penelitian menunjukan bahwa ada peningkatan sifat tahan api pada kain katun yang telah diberikan perlakuan. Penilaian sifat tahan api diuji dengan menggunakan metode uji standar tahan api cara vertikal ASTM D6413-08. Pada penelitian ini telah dilakukan perlakukan plasma bertekanan atmosfer dengan variasi waktu 4 menit dan 8 menit. Hasil penelitian menunjukan bahwa kain katun dengan perlakuan metode perendaman pada ekstrak daun bayam dan pra-perlakuan plasma bertekanan atmosfer memiliki sifat tahan api yang paling baik diantara metode lainnya. Telah ditemukan pula pada studi ini bahwa waktu perlakuan plasma 4 menit berpengaruh terhadap sifat tahan api kain katun.

Surface modification of polyester-cotton (TC 70%) fabric by corona discharged plasma with tip-cylinder electrode configuration-assisted coating carbon black conductive ink for electromagnetic shielding fabric

“…The use of electronic devices has been increased rapidly in recent years. Several researchers (Al-Saleh & Sundararaj, 2009;Avloni et al, 2007;Ma et al, 2014;Mariotti et al, 2016;Morent et al, 2008;Putra, Mohamad, & Wijayono, 2020) have shown the application of the use of physics in the case of textiles both in materials science and environmental engineering especially in smart and functional material. The application of physics and chemistry, especially in some textile industries, has been widely applied (e.g., plasma physics in textile processes, the electromagnetic field for EMI Shielding, etc.).…”

“…Several researchers (Chen, Lee, Lin, & Koch, 2007;Cheng et al, 2015;Hwang, Chen, Lou, & Lin, 2014;Kumar et al, 2015;Li, Zhang, & Yin, 2012;Ozen, Usta, Yuksek, Sancak, & Soin, 2018) in the field of textiles are currently trying to make anti-radiation clothing with a material and coating process that is simple and affordable but also has good washing test resistance. Some researchers (Boonchoat, Satreerat, & Hodak, 2010;Jung & Choi, 2007;Lieberman & Lichtenberg, 1994;Murti & Putra, 2020;Putra, Fitri, Purnama, & Mohamad, 2020;Putra, Mohamad, & Wijayono, 2020;Putra, Mohamad, & Yusuf, 2020) stated that the method of radiation exposure by plasma generators has been shown to strengthen the adhesive material coating force and is proven effective in absorbing the material to be deposited. Some researchers (Ozen et al, 2018;Putra, Fitri, et al, 2020) also stated that to obtain anti-radiation material, the textile fabric must have a conductive property but not oxidize easily, one example of the recommended material is carbon black.…”

“…Cheng et al, (2015) reported that they have succeeded in developing conductive fabrics as anti-radiation material for electromagnetic waves. several researchers (Jung & Choi, 2007;Mariotti et al, 2016;Murti & Putra, 2020;Putra, Fitri, et al, 2020;Putra, Mohamad, & Wijayono, 2020;Rausher et al, 2010) reported that they also researched textile materials with the topic of fine coating engineering studies with either plasma method or conventional method on textile materials. Several studies (Avloni et al, 2007;Kumar et al, 2015;Li et al, 2012;Morent et al, 2008;Safarova, Tunak, Truhlar, & Militky, 2016;Safarova & Militky, 2012) showed that electronic devices such as smartphones has electromagnetic radiation that can cause negatively affect the user's body.…”

According to several researchers (Lieberman & Lichtenberg, 1994;Putra, Mohamad, & Wijayono, 2020;Rausher et al, 2010;Shishoo, 2007;Sjaifudin et al, 2014) Plasma is the fourth material after solid, liquid and gas. Plasma is defined as an ionized gas of free particles.…”

“…However, some researchers (Avloni et al, 2007;Cheng et al, 2015;Jung & Choi, 2007;Kumar et al, 2015;Li et al, 2012;Ma et al, 2014) have some problems to coat the conductive material and to fabricate uniform coating film. Some researchers (Shishoo, 2007;Rausher et al, 2010), ( Ma et al, 2014;Morent et al, 2008;Putra, Fitri, et al, 2020;Putra, Mohamad, & Wijayono, 2020) reported that the advantages of using plasma technology include increasing water absorption, increasing adhesion forces, sterilization, improving the etching process and so on. The results demonstrated that the effect of modifying the superficial surface could change the material's mechanical properties as a whole: mass loss, fabric tenacity and surface roughness, and increased adhesive force.…”
