Jute Nonwovens.

The tensile strength and thickness compressibility of needle punched fabrics are important criteria for their filtration, absorption, and insulation performance. Researchers investigating how the manufacturing parameters of needle punched jute fabrics influence mechanical properties determined the effects of basis weight, needling density..

Thermo-Insulating Properties of Perpendicular-Laid versus Cross-Laid Lofty Nonwoven Fabrics.

An investigation into the thermal insulation properties of perpendicular laid and conventional cross laid lofty nonwoven fabrics used a new static method with a heat flux sensor to define the relationship between the thermal conductivity and material density of samples manufactured from fibers with different fineness ratings. Thermal cond..

Fleece Processing with Ultrasound - Fast and Low in Vibration.

Ultrasonic technology is used increasingly to manufacture nonwoven fabrics. Sustaining production speeds in excess of 100 meters per minute with band widths of over 2,000 millimeters and achieving high quality reproducibility require maintaining the spacing between welding bearings and roller to within a few thousandths of a millimeter. K..

SEM Evaluation of Water Treatment Filtration by Non-Woven Textiles.

Researchers used scanning electron microscopy (SEM) to evaluate the efficacy of water treatment filtration systems using geotextiles manufactured from nonwoven fabric as filters. Testing materials included needlepunched polypropylene fabric from Amco Fabrics and Fibers Company. Process stages at the Rosedale Water Treatment Plant in Canad..

Sulzer Textil AG's G6300 rapier loom has a newly designed high performance drive and direct drive for the rapier tape that confer a powerful torque for rapid acceleration and deceleration. Electronic control of warp letoff and fabric takeup with advanced servo motor technology facilitates operations. These looms can be equipped with a qui..

The Medican Market: Not Your Everyday Textiles.

Medical and healthcare textiles encompass a wide range of products found in operating rooms, hospital wards, local clinics, physicians' offices, nursing homes, dental clinics, pharmacies, and medical laboratories. Because of their technical properties, spun bonded fabrics are competing with conventional industrial woven and knit fabrics. ..

Influence of Nonwoven Structure on the Burning Behavior of Bondings Including Fabrics and Nonwovens.

Researchers studied the buring behavior of nonwoven fabrics using the DIN 75200 horizontal flame spreading test. The study determined the structural, fabric, and physical properties that influenced the burning process. Scanning electron microscopy and laser confocal microscopy revealed fabric surface and internal structural parameters. Da..

Effect of the Binder on the Capillary Properties of Nonwoven Materials.

Fiber type and linear density, polymer latex type, and the composition of the impregnating compound affect the capillary properties of nonwoven fabric impregnated with polymer dispersions. Incorporation of modifying additives on the fiber surface or in the impregnating compound significantly alters fabric impregnation kinetics. The most h..
