Developments in Non-Woven Manufacturing
Techniques
Nonwovens are fibers in the form of webs, which have to be bonded. Fibre bonding methods are generally chemical, thermal and mechanical. The development are taken place in the process of manufacturing a nonwoven such as spun bonding, spun lacing, air laying, cross lapped nonwovens, formation of random nonwoven webs with the static method, needle punching nonwoven. Due to continuous research a newer nonwoven products started developing such as development of eco-friendly Nonwoven product by solubalisation of viscose, production of nonwoven fiber board panel and latex foam sheet using coir and polypropylene blend, needle punched nonwoven blankets, the vertical and horizontal type of nonwoven products also starts utilizing for automobile interiors.
DEVELOPMENT IN WEB FORMING PROCESS
This development is taken place for random fibre arrangements in roller card web processed by different voltages and electrode panel shapes. In this development it has been found that by changing shape of electrode panel can provide better random effects when the same voltage is used.
