Cutting and Bonding of Nonwovens with Ultrasonics.

Manufacturers of filters, protective clothing, hygiene products, and wound fabric covers use ultrasonics for cutting and bonding nonwoven fabrics, which increases production speeds and reduces energy consumption. Ultrasonics bonds fabrics without affecting fabric properties, such as softness, flexibility, and breathability. For cutting no..

Application of Cellulosic Fibers in Nonwovens.

The principal use for cellulosic fibers within the nonwoven fabrics industry occurs in the blending of cellulosic fibers with polypropylene and polyester fibers. Hydroentanglement is the principal method for manufacturing nonwoven fabrics using blends of cellulosic and polypropylene or polyester fibers. Adding modified cellulosic fibers t..

Ultrasonic Efficiency.

Hermann Ultrasschalitechnik of Germany developed a noncontact and nonwear technology for continuous ultrasonic welding that combines special ultrasonic tooling with state-of-the-art drum technology for the printing and packaging industry. The precise dire

IDEA 98 -- Big Nonwovens Show Aims to Break Records.

Three hundred exhibitors are expected at IDEA 1998. Attendance is predicted to reach 7,000. Twenty-five countries and over 100 new companies will be represented. Robert Rufli will give the keynote address titled How Will the future of Our Industry Look if All the Forecasts Come True? Topics to be discussed include the effect of the merger..

TAPPI Conference and Trade Fair to be Held.

The TAPPI 1998 Nonwovens Conference and Trade Fair, held in March, 1998, featured presentations by process engineers, research scientists, managers, quality assurance and product development personnel, academicians, and marketing and sales professionals.

Needlepunched Nonwovens in Braxil.

Needle puched fabrics account for approximately 50 percent of the Brazilian nonwoven fabrics industry. Sales and production capacity have increased significantly in Brazil during each of the past three years. Sixteen companies manufacture needle punched f

Elastic Nonwoven Fabrics.

Elastic nonwoven fabrics provide stretch and recovery in one or more directions and consist of composite web, resin to web, and elastomer bonded elastic nonwoven fabrics. Composite elastic nonwoven fabric manufacture sandwichs a layer of spandex filaments between two prebonded nonwoven webs, chemically bonds the layers by nip saturation, ..

Nonwoven Textiles.

Researchers tested three dimensional polypropylene/woolenized jute blend needle punched fabrics for stress behavior angles, thickness and compression recovery, and varying thickness at different area diameters. A Universal Instron Tensile Tester measured tenacity and extension at the brake. A Mercer Thickness Gauge measured the percentage..

Structure-Property Behaviour of Multi-layer Melt Blown Webs.

A study examined the structure and properties of multilayer melt blown microfiber webs (webs with multiple layers within each microfiber). Researchers used polyethylene, polypropylene, polyethylene terephthalate, polyurethane, polyvinyl alcohol, and poly-4-methyl-1-pentene to produce multilayer webs with alternating layers. The method all..

Biodegradable Melt Blown Polyester Cotton-Core Laminates.

Biopol is polyester resin derived from bacteria using 90 percent percent polyhydroxybutyrate and 10 percent polyhydroxyvalerate. Tests mixed the resin with polypropylene (PP) in various proportions, manufactured melt blwon webs weighing approximately 34 g
