A Preliminary Study for Modification of Wetting Properties on Cotton Polyester (TC) Fabric Surface Using Atmospheric Plasma Corona Discharge Technology

Abstract

Textile materials generally have intrinsic properties, such as flexibility, light volume density, strength, tenacity, comfort and softness. Based on these characteristics, the textile material is generally given a special additional function, such as hydrophobic or hydrophilic properties. The addition of these special functions to the textile industry is generally using conventional wet methods that require more energy and water as well as more chemicals need and expensive price. Plasma technology is one of the dry process technologies and it can reduce the use of chemicals that can pollute the environment. This article describes the application of atmospheric plasma corona discharge technology in the textile sector, especially its use in modifying wetting properties on the surface of polyester cotton (TC) 70%. The results showed that by varying the time of plasma treatment on 70% TC cotton polyester fabric with density of weft and warp respectively 70 strands / inch and 60 strands / inch we found that there was a change in the wetting properties of the fabric with increasing hydrophilic properties of the fabric. SEM images show the example of morphology of cotton polyester fabric surfaces treated with time of exposure by plasma at one minute (60 s) at 3 kV of output voltage as the optimal exposure time and applied voltage to enhance the wetting properties.

“…The details of the corona discharged plasma system was given in our previous studies. (Putra, Fitri, et al, 2020;Putra & Wijayono, 2019).…”

“…Some industries, such as plastics, polymers, textiles, metals, and ceramics, use plasma technology to modify surface properties. Several researchers (Boonchoat et al, 2010;Morent et al, 2008;Putra, Mohamad, & Yusuf, 2020;Putra & Wijayono, 2019;Shishoo, 2007) stated that O 2 , N 2 , and Argon (Ar) gases change the fabric's properties to be more hydrophilic (easier to absorb liquid) while C 2 F 6 , SF 6 's gases will change the fabric's properties to hydrophobic (difficult to absorb liquids). It is common practice to coat the textile fabric surface with a thin film as an electronic device (e.g., textile solar cell, textile capacitor, textile sensor, and shielding material).…”

“…However, it is also commonly used for needs other than clothing, such as furniture, the automotive industry, household utensils, etc. Some researchers (Morent et al, 2008;Putra & Wijayono, 2019;Rausher et al, 2010) claimed that polyester fabric has properties such as strong enough, durable, and can be used for various purposes (because this material is also not easy to absorb water or sweat as well as anti-fungal or bacterial) but uncomfortable, while cotton has good comfort properties but not strong enough and not durable. In this study, plasma was used to change the surface and wetting properties of the TC 70% fabric to enhance the coating process.…”

Plasma Non Thermal Sebagai Sterilisasi Masker untuk Inaktivasi Virus Corona (COVID-19)

“…Kondisi kuasinetral merupakan daerah dimana terdapat kerapatan ion (ni) yang hampir sama dengan kerapatan elektron (ne) sehingga dapat dikatakan ni  ne  n, dengan n menyatakan kerapatan secara umum yang disebut kerapatan plasma [17]. Penerapan gelombang elektromagnetik Dan fisika gelombang seperti sinat ultraviolet dan gelombang plasma di bidang medis telah banyak diteliti oleh banyak fisikawan [18][19][20][21][22][23][24][25][26][27].…”

“…Beberapa peneliti [19,[24][25][26][27] menyatakan bahwa energy yang dibutuhkan untuk pembangkitan plasma harus tercukupi untuk menghasilkan gas yang terionisasi dan pada umumnya besar tegangan listrik yang digunakan untuk mengionisasi gas lingkungan memiliki orde kilovolt. Beberapa jenis plasma non thermal dapat dimanfaatkan sebagai generator pembangkit ozon khususnya plasma dengan lucutan pijar korona.…”
