Plasma surface treatment on nylon fabrics by fluorocarbon compounds

Abstract

SynopsisNylon fabrics were treated by low temperature fluorocarbon plasmas. All of the fluorocarbon plasmas applied altered the surface of nylon fabrics to be hydrophobic and water-repellent. The durability of hydrophobicity and water repellency was examined by measurements of the water contact angle, the water droplet rolling-off angle, and the breakthrough water pressure after plasma-treated fabrics were washed. I t was found that the structure of starting fluorocarbon and the plasma energy input were important factors in the durability. After washing, surface dynamics were investigated on different drying conditions. It was found that chemical composition and water repellency were dependent on drying conditions because of rotation of hydrophobic segments on the surface of fabrics.

ESCA and SIMS studies of plasma treatments of intraocular lenses

“…The non-uniformity of the F and C2 images in Fig. 4 could be caused by several factors : (1) non-uniformity of coating thickness and/or lateral inhomogeneity, effectively resulting in variations in concentration ; (2) surface potential variations attributable to factor (1) and to the fact that the sample is not flat; (3) shadowing; (4) sample damage.…”

Influence of Low Temperature Plasma Treatment on the surface, Optical and DC Electrical Properties of jute

“…However, these plasmas can cause some chemical and physical reactions on the surface of substrates because of highly energetic species such as free radicals, ions, photons and ultraviolet (UV) radiations. The high-energy electrons and low-energy molecular species in a LTP can initiate reactions in the plasma volume without excessive heat causing substrate degradation [15]. LTP are particularly suited to apply to textile processing because most textile materials are heat sensitive polymers.…”
