Richard Hough sees success in geotextile, medical markets.

New investment during 2012 by U.S. technical nonwovens producers is highlighting the benefits of calendering and water extraction technology from U.K.-based Richard Hough Ltd. (RHL). Significant installations so far this year have been commissioned by leading suppliers to the geotextiles and medical sectors.

RHL Syncast polyamide-covered calender rolls have been delivered for two new nonwoven geotextiles lines, one in Georgia and one in South Carolina each operated by industry-leading companies. Another recent contract has led a major producer of nonwoven surgical garments to purchase its second Roberto, Rlit's squeezing roll.

"We are delighted at these successful contracts in the American nonwovens market, assisted by our representative Ford Trimble Associates," says Anthony Ashton, RHL managing director. "RHL manufactures highest-quality calender and squeezing rolls that are not available from any U.S. manufacturer, so we are contributing something unique to the industry. The quality and endurance of our Syncast nylon calender rolls is legendary and the energy-saving ability of the Roberto rolls means payback within months."

RHL has specialized in calender and squeeze rolls for 200 years and in the past decade has launched a series of technical innovations that have improved processing efficiency and reduced both production costs and energy bills in these applications.

The Syncast installations in North America are both for 230-inch wide non-wovens calendering lines, each using two Syncast rolls. Made on a technically advanced centrifugal casting machine, Syncast polyamide rolls and sleeves are based on a highly elastic thermoplastic polymer, specially developed for textile calender rolls. They offer high performance and rapid payback, avoiding the need for a major calender rebuild. In use, the high level of elasticity guarantees minimum surface marking and shape distortion, as well as excellent runability and maximum service life, the company says.

RHL can supply roll covers of up to seven meters face length and up to 1.25 meters diameter, making the Syncast products ideal for geotextile applications.

Many thousands of Roberto rolls have been sold worldwide since their invention by Robert Oliver, of David Bentley/Modern Rollers. RHL has owned the Roberto technology since 2005, and its global success has continued as a high-performance replacement for conventional rubber or PU rolls, for efficient liquid extraction from woven, knitted and nonwoven fabrics. The Roberto uses a special microporous covering to extract the maximum liquid from the fabric, achieving 30% less residual moisture than normal rubber rolls with consequent massive cost savings.
