Anti-Pilling Plasma Treatment
A designed industrial scale clothing plasma treatment system provides a green approach for functionality finishing and minimising the pilling for wool and cashmere knitwear.
Pills are formed by the entanglement of loose fibres that protrude from fabric surface. Loose fibres will develop into fluffy tiny balls hooked to the fabric during wearing or washing. This treatment is based on the generation of the ionized gas plasma composed of ions and argon gas particles to interact with the garment. By modifying the surface structure of fibres, plasma treatment will increase the co-efficient of inter-fibre friction and thus reducing fibre migration. Therefore, the pilling resistance can be significantly enhanced with the pilling grades improved by 1 to 2.
Most of the plasma treatment system on anti-pilling available in the market is for fabric scale production. Engineering of this newly developed system has achieved significant industrial breakthrough.
In the systems 10 garment racks are installed which are large enough to hold 20 pieces of knitwear to be treated at the same time. The treatment process is controlled by a linear motion unit which will rotate during the treatment process, making the treated effects more even on the garment surface. The whole treatment system contains two vacuum chambers which operate alternatively. This design helps increase production efficiency. For example, the treatment process is carried out in one chamber while the after treatment process can be done in another chamber.
Besides, a touch-screen panel is designed for the control of the system. The application is user-friendly and easily operated by workers.
