Comparison of Trends in Latex Emulsions for Nonwovens and Textiles: China and the United States.

Despite differences in the size of the market, production output, and the mix of technologies used in the nonwoven fabric industries in the United States and the People's Republic of China, the type of emulsions used in nonwoven and textile applications are very similar. In 1996, the United States and Chinese nonwoven and textile markets ..

Higher production and improved quality of nonwovens

Web preparation involves the opening and mixing of the fibres and creating a uniform mass flow length- and crosswise. Web quality depends essentially on these process steps. Opening, mixing and homogenization each take place in individual steps, both serially and in parallel. When the fibres are opened, for instance, they are also intermi..

Fatigue behavior of aramid nonwoven fabrics under hot-press conditions. Part VI: Effect of stable base fabrics on mechanical properties

The purpose of this investigation is to find the most suitable design for heat-resistant nonwoven fabrics to be used as a component of laminated materials. In the earlier parts of the series [1-5], we found that needle punched nonwoven fabrics have superior recovery from pressure compared to paper-like nonwoven and four-ply woven fabrics...

New developments in bleached cotton for nonwovens

During recent years considerable marketing and product development effort has been directed towards the growth of bleached cotton as a fiber for new nonwovens markets. This paper will describe technical advancements in this area, including improved openness and cleanliness of bleached cotton fiber, and new engineered finishes and fiber tr..

Preparing cotton, web forming and bonding methods for cotton nonwovens

To produce nonwoven fabrics from staple fibers a web of fibers must be formed. The web forming processes used for producing webs of cotton fibers will be discussed. To produce nonwoven fabrics, fiber webs are bonded together to impart strength. The bonding techniques that cotton lends itself to will be covered. Properties and uses of cott..
