Surface properties of radio frequency plasma treated wool and denim fabrics

Purpose The purpose of this paper was to investigate the effects of hydrochloric acid (HCl), hydrazine, methyl methacrylate, styrene and hexamethyldisiloxane by radio-frequency (rf) plasma graftings on surface properties of wool and denim fabrics. Design/methodology/approach During plasma treatments, processing time was varied under optimized plasma conditions (50 W, rf: 13.56 MHz). All fabrics were comprehensively investigated by means of scanning electron microscopy-energy dispersive X-ray spectroscopy and contact angle measurements. Findings The experimental data shows that the rf-plasma processing has important effect on the wettability properties of wool and denim fabrics. The results indicated that HCl plasma treatment significantly improves the hydrophilicity of wool and denim fabrics. Originality/value The research on wool and denim fabric treatment by plasma is original.

Electrospun fibers coated onto plasma modified and nonmodified wools

Summary form only given. Unlike conventional fiber spinning techniques (wet spinning, dry spinning, melt spinning, gel spinning), electrospinning has been recognized as simple effective and an efficient technique for the fabrication of polymer nanofibers and nanofiber non-wowen mats1,2. Moreover, this technique can provide possibility to control over the resultant morphology of the nanofiber3.

A study on characterization of polymer-coated wool fabrics using plasma polymerization

Many great investigations and new techniques focused on the study of textile to improve textile surface properties such as wetting, antistatic, electrical conduction, penetration, and so on1,2. The static charge is a critical factor and an important limitation for many applications such as garments in direct contact with human skin3,4. Both low-pressure and atmospheric plasma systems can be used for novel antistatic acquisition; processing fibers, yarns, fabric. Wool is good substrate for plasma modification due to outermost part of fiber that is consisted of lipid layers and ionizable functional groups5,6.

Plasma modified chitosan/N-acetyl-2-pyrazoline derivative nanofibers

A series of plasma modified chitosan/N-acetyl-2-pyrazoline derivative fibers (PMCh/NAP) were obtained by using an electrospinning method. The result compounds were synthesized from chalcones which obtained by Claisen-Schmidt condensation of ferrocenecarboxaldehyde with hetaryl methyl ketones1. The synthesized chalcone derivatives were then treated with hydrazine hydrate in glacial acetic acid medium to produce N-acetyl-2 pyrazoline derivatives2.
