Some plasma treatment of PET fibres and adhesion testing to rubber

Abstract

Polyethylene terephthalate fibre cords were modified with oxygen, water or hydrogen peroxide cold plasmas or coated with acrylic acid, butadiene and hydrogen sulfide cold plasmas. Treated surfaces were studied in terms of their surface energies by contact angle measurement and morphology by scanning electron microscopy. Plasma treated cords were coated with a resorcinol‐formaldehyde latex and tested as rubber reinforcing materials. Oxygen plasma treatment leads to the greatest increase in adhesion but hydrogen sulfide also yielded promising results.

Effect of spin finish on fiber/binder adhesion in chemically bonded nonwovens

“…Concerning the choice of the fiber, polyester [poly(ethylene terephthalate) (PET)] fibers were selected because of their widespread use in the NW industry. However, they have an intrinsic poor affinity for the binders, which is in contradiction with the fact that a good uphold of the fiber/ matrix composite depends on the adhesion between these two elements 1–6. The aim of this article is to study the fiber/binder adhesion to determine the different physicochemical parameters that can improve this adhesion, the surface properties in particular.…”

Improved adhesion property and electromagnetic interference shielding effectiveness of electroless Cu‐plated layer on poly(ethylene terephthalate) by plasma treatment

“…Recently, the metallization of polymer materials has attracted more and more attention. Many polymer films, fibers, and plastics are metallized for extensive applications in food packaging, microelectronics, computer technology, and the automotive industry to provide an electromagnetic shielding property 1–6. Metal foil and laminates, conductive paints and lacquers, sputter‐coating, vacuum deposition, flame and arc spraying, and electroless metal plating are recently developed metal‐coating techniques.…”

“…Since the surface activity of the polymer substrate is generally low with metals, to enhance the adhesion, the polymer surface must be formed of a suitable irregularity for a mechanical anchorage between the catalyst and polymer surface and the introduced functional groups for an affinity with the catalyst 3, 11. In this research, therefore, plasma surface treatment was applied on the PET film to improve the surface adhesion and to increase the amount of the chemisorbed catalyst, thereby increasing the EMI–SE and the adhesion of the metal layer 12.…”
