Nonwoven Mill Roll
Nonwoven mill rolls are specialized industrial rollers used in manufacturing and processing nonwoven fabrics.non-woven mill roll They’re designed to perform in harsh, high-stress environments that require extreme temperature and moisture conditions. They also have the ability to withstand abrasions and other external stresses that would damage normal steel or polymer rollers. This makes them ideal for a wide variety of applications in industries like metal fabrication and coil processing, including blank/coil washers, primary metal processing lines, caustic cleaning, and pickling.
Non-wovens are fabrics made of small fibers arranged in sheets or webs and bound together by mechanical, thermal, or chemical processes.non-woven mill roll They’re characterized by their high-fibre density and porous structure, with the individual fibres often oriented in different directions. They can be used for many applications requiring textiles, such as filtration and hygiene products. They can be made to be disposable or durable consumer goods, such as hygienic pads, towels and washcloths; industrial wipers; or even costumes for special events.
The main processes for producing non-wovens are spun-laid (bonded), melt-blown, or air-through.non-woven mill roll Spun-laid non-wovens start with extruding a low viscosity polymer, which is then attenuated or quenched as it leaves a spinneret, leaving long filaments that are deposited on a conveyor belt to form the web. They can be made from a wide range of raw materials, including polypropylene, polyester and polyethylene.
Melt-blown non-wovens are similar to spun-laid, but the process starts with a hot air stream engulfing a molten polymer as it exits the melter.non-woven mill roll This gives it a higher tensile strength than spun-laid, but the result is a thinner and weaker web. It’s possible to make the web stronger by co-extrusion or combining polymers to create bico non-wovens.
Air-through non-wovens have a more uniform web that allows for greater control of the flow of air or liquid through the material.non-woven mill roll They can be made from a wide variety of raw materials, and are able to incorporate a number of features for specific uses. For example, they can be made conductive, flame retardant, water repellent, breathable or antistatic. They can also be flocked, printed or dyed to add extra properties.
A high coefficient of friction can reduce hydroplaning and slippage, whereas the ability to absorb liquids suppresses aquaplaning. They also provide superior squeezing and washing performance, and they’re often engineered with surface textures that can be modified for specific properties.
A good non-woven roll should have a long lifespan and maintain consistent performance, so it can be repaired instead of replaced. It should also have an excellent record of safety. NCCM produces a variety of non-woven rolls for various line types, from forming to washing to squeezing. Our bridle roll, for example, is world-renowned for its longevity and performance in automotive blank/coil washers, primary metal lines, and other demanding lines. Its exceptional wear resistance paired with its high coefficient of friction and superior fluid control dominance is an industry standard. We offer a full range of non-woven rolls, from standard diameters to custom sizes and shapes, as well as abrasion resistant coatings to protect them against harsh metals and chemicals.
