Flax fibers were modified by argon and air atmospheric pressure plasma treatments to improve the mechanical properties of flax fiber-reinforced unsaturated polyester composites. Plasma carried out at powers 100, 200, 300 W. Both surface conducted tensile strength, modulus, flexural interlaminar shear strength (ILSS), Mode I fracture toughness (G IC ), II IIC ). Moreover, maximum improvement in was obtained after treatment fiber a power Tensile ILSS, G , values composites increased nearly...

The purpose of this study was to investigate the extract Catalpa bignonioides plants and characterize novel natural cellulosic fibers from fruits as an alternative material for sustainable products. tree contains pharmacologically active compounds is found all over world. were easily extracted in environmentally friendly manner plant characterized terms their chemical, thermal, physical properties. (CBF) composed cellulose (58.3%), hemicellulose (3.1%), lignin (38.6%) had a low density...

Adapting green technologies to the leather industry plays a crucial role in environmental protection by reducing wastewater load, using fewer chemicals, minimizing waste, saving energy and water, costs, increasing productivity. Plasma treatment, accepted as clean technology, is mostly used textiles compared limited studies leather. Thus, this study will be first respect. Crust leathers, treated with air argon atmospheric plasma under conditions of 130 W, 100 s, were dyed acid metal complex...

The aim of this study is to characterize linden fibres as a novel cellulose-based fibre be used reinforcement material in composites and investigate the adhesion property unsaturated polyester. Up now, there no report regarding potential usability composite applications. Linden were extracted from stem plant Tilia rubra DC. subsp. caucasica (Rupr.) V.Engl. Characterization was studied by Fourier transform infrared, X-ray photoelectron spectroscopy, thermogravimetric analysis, diffraction...

ABSTRACT To increase the mechanical properties of recycled carbon fiber‐reinforced polypropylene (PP) composites, fibers (RCF) were subjected to atmospheric plasma treatment at different powers (100, 200, and 300 W). The changes on surface topography roughness RCF examined by atomic force microscopy. Plasma increased value RCF. variation elemental compositions tensile strength determined using X‐ray photoelectron spectroscopy test, respectively. Plasma‐treated RCF‐reinforced PP composites...

Abstract The effect of atmospheric air plasma treatment jute fabrics on the mechanical properties fabric reinforced polyester composites was investigated. were subjected to different powers (60, 90, and 120 W) for exposure times 1, 3, 6 min. effects interlaminar shear strength, tensile flexural strength based evaluated. greatest ILSS increase about 171% at power W time It is inferred that improves interfacial adhesion between fiber polyester. This result also confirmed by scanning electron...

The effects of enzymatic treatments on the properties coir fiber-reinforced poly(lactic acid) (PLA) were not found in literature. Accordingly, various mechanical performance PLA composites investigated current study. Four different enzymes, namely lipase, lactase, pectinase, and cellulase, used. determined by tensile, flexural, impact tests, dynamic analysis. According to test results, use enzyme treated fibers affected except for flexural with extents depending upon their type. tensile...

Ceiba pentandra (L.) Gaertn (kapok) fiber, a natural and renewable material, has received increasing attention in recent years for its intrinsic properties. In this study, pretreatment of kapok fiber was performed green way by using atmospheric plasma, together with pectinase lipase enzymes no hazardous chemicals used. A response surface methodology (Box-Behnken experimental design) been used to design optimize an environmentally friendly sustainable scouring process fibers. Predicted values...

In this study, linen fabrics were inkjet printed with reactive dyes after air argon plasma treatments. Sodium alginate (ALG), carboxymethlycellulose (CMC), chitosan (CHT), ALG+CHT, CMC+CHT, and their combinations, used as pretreatment print pastes prior to pretreatment. The color yield the fastness properties of evaluated. CMC+CHT paste gave best or without Colorfastness values not affected by type paste. However, slightly improved colorfastness.

Keratinases have been used because of their ability to separate keratin that cannot be broken down by common proteases in the processing wool fabrics textile industry. In this study, enhance keratinase production from Streptomyces sp. 2M21, three different detergents (SDS, Triton X-100, Tween 80) two concentrations (0.5%, 0.1%) were added fermentation medium containing raw sheep as a solid substrate and results evaluated compared control groups. The highest enzyme activity was obtained 0.5%...

Abstract In previous studies; effects of enzymatic treatments on linen fabrics have been mostly investigated in terms wettability, sorption properties, whiteness‐yellowness index, and K/S values after dyeing. However, surface chemistry topography enzyme‐treated not reported enough. The aim this work was to examine the effect pectinase structure chemical properties greige by using instrumental techniques. After treatment, adequate removal noncellulosic impurities from fiber has proved AFM...

 Bu çalışmada, komonomer içeren poliakrilnitril (PAN) kumaşlara güç tutuşur özellik kazandırmak için bor oksit ve borik asit kullanılmıştır. Borlu bileşikler, atmosferik plazma modifikasyonu sol-jel yöntemlerinin çeşitli kombinasyonları kullanılarak uygulanmıştır. Uygulama sonrası tutuşma süreleri, klasik emdirme yöntemiyle uygulanan kumaşlar ile karşılaştırılmıştır. Bor farklı koşullarda işlem gören tüm numunelerin süresinde artış görülmüştür, ancak en yüksek plazma+sol-jel yöntemi...
