Pewarnaan benang dengan pewarna alami untuk kain tenun sudah menjadi trend saat ini. Sutera merupakan serat alam yang sering digunakan untuk kain tenun dan menghasilkan intensitas warna yang baik ketika diwarnai dengan pewarna alami seperti ekstrak gambir. Pewarna alami yang diekstrak ulang dari gambir asalan telah diaplikasikan untuk mewarnai benang sutera. Penelitian bertujuan untuk menganalisis ukuran dan dispersi partikel dari ekstrak gambir serta melihat pengaruhnya terhadap hasil pewarnaan pada temperatur dan waktu pencelupan yang berbeda. Mordan CaO digunakan untuk membangkitkan dan mengunci warna dengan metoda pasca mordanting. Proses pewarnaan dilakukan pada temperatur 30, 50 dan 70°C dengan waktu pencelupan 5, 15 dan 25 menit. Ekstrak gambir dianalisis dispersi ukuran partikelnya menggunakan particle size analyzer (PSA), sedangkan benang sutera yang telah diwarnai dievaluasi nilai kolorimetri dan ketahanan luntur warnanya. Hasil penelitian menunjukkan bahwa perlakuan pada temperatur 70°C dengan waktu pencelupan 15 menit memberikan intensitas warna optimal dan ketahanan luntur warna terhadap pencucian 40°C dan panas penyeterikaan rata-rata bernilai baik sampai sangat baik (4-5), sedangkan terhadap paparan sinar terang hari bernilai cukup (3).

“…109 The obtained physiochemical changes of silk fibers after APP treatment can improve hydrophilicity, 106 dyeability in terms of dye exhaustion, color depth, homogeneity, and even fastness of certain types of dyes. [109][110][111] Zhang et al 112 have improved the printability of silk fabrics with pigment ink-jet printing by pretreating the fabrics with DBD air plasma. The applied pretreatment improved pigment color yield as well as anti-bleeding performance, which are two of the main problems when pigment printing on silk fabrics.…”

This paper gives an overview of atmospheric pressure plasma types used in the textile industry and recent developments in plasma treatments of textiles. It investigates the topic of the influence of atmospheric pressure plasma treatment on the surface properties of materials made from natural and synthetic fibers. Through plasma induced physical and chemical reactions occurring in the textile surface layer, significant modifications in micromorphology and reactivity can be achieved. In addition to cleaning, etching, and activation, great efforts have been made in the development of plasma polymerization processes under atmospheric pressure. Utilization of atmospheric pressure plasma technology in the textile industry offers a new perspective on surface modification and functionalization. This paper gives a summary of textile properties achieved using plasma and the underlying processes based on relevant findings obtained from prominent research.

Ultrasonic Bioconversion of Silver Ions into Nanoparticles with Azadirachta indica Extract and Coating over Plasma‐Functionalized Cotton Fabric

An ultrasonication approach was adopted for Azadirachta indica driven bioconversion of silver salt into silver nanoparticle (AgNPs). These nanoparticles were coated over plasma functionalized cotton by using a pad dry cure technique. For pre‐coat surface functionalization, the cotton fabric was exposed to an open air single dielectric barrier discharge (DBD). The emission spectrum revealed that DBD consisted of NO, O3, O, O2+ , O+, OH−, N2 and N2+ species. The plasma treatment produced negative radicals on the surface and improved the adhesion of fabric for nanoparticles. The crystallographic analysis revealed cubical structure of nanoparticles with average size of 25 nm. The fabric got fully covered with AgNPs after five pad‐dry cycles. Nanoparticles together with neem extract promoted the antimicrobial activity of the coated fabric. The inhibition zone of the silver coated fabric against E.Coli strains increased from 6 mm to 14 mm. The conductivity of fabric after 3, 5 and 7 cycles remained 2.56× 10−2, 2.63× 10−2 and 2.67× 10−2 Siemens/cm, respectively. The coated fabric showed UV protection factor in the range of 210–269. The transmittance of UV−A radiations and UV−B radiations from the uncoated fabric was 19.27 % and 7.84 %, respectively, which reduced to 0.76 % and 0.24 % after 7 pad dry cycles.
