Evaluation of Nonwoven Fabrics with the KES Testing Equipment.

Research on the mechanical properties of commercially available nonwoven fabrics used the Kawabata Evaluation System (KES) to test samples. The constructions tested included resin bonded, spunlaced, needle felted, woolen felted, and spun bonded constructions. The testing focused on comparative bending and shear behavior in the machine, cr..

Characterization and Testing of Nonwovens with Emphasis on Absorbency.

Nonwoven fabric characterization and testing maximizes production control, process development, product testing and quality control, research, and product specifications. Current standardized tests measure absorption, abrasion resistance, bursting strength, electrostatic properties, flammability, optical properties, permeability, repellen..

Selecting the Right Cotton Fiber for Nonwoven Products.

Nonwoven products may require a fiber coarseness and resiliency not characteristic of common upland cotton varieties. Researchers grew Dessi (gossypium aboreum) cotton, an Asian variety, and subjected the harvested fibers to tests with high volume instruments (HVI) and Uster's Advanced Fiber Information System (AFIS). HVI data comprised m..

Structure and Properties of Carded Glass Composites.

Owens Corning Fiberglas developed short staple glass fiber webs produced by carding as a replacement for asbestos. Carding orients the fibers and increases the directional strength translation efficiency. The oriented webs serve as fibrous preforms for composites or, when stacked, as quasi-isotropic composites. Carding also uniformly mixe..

The Balance of Strength and Softness in Saturation-Bonded Polyester Nonwovens Used for Interlinings.

The performance of interlinings manufactured from nonwoven fabrics balances strength and softness. When strength is more important than softness, the quantity of conventional latex binder and/or melamine-formaldehyde resin added to the nonwoven fabric is increased, which increases durability and stiffness and degrades tactile hand. Rohm a..

High-Performance Nonwovens Card

Developments in polymer and process technology have led to faster production speeds in nonwoven fabric manufacture. Producers operating in practical mill conditions can manufacture nonwovens fabrics at speeds of 260 meters per minute and effective carding machine widths of 4,000 millimeters, corresponding to a total output rate of greater..

Polyamide 12 fibres for paper manufacturing felts

When compared with polyamide 6 and 66 for new paper making felts, PA12 Grilamide fibres have several advantages. The felts exhibit better wearing behaviour on the paper presses, mostly with regards to permeability, abrasion, resiliency and compressibility. Other pluses for PA12 fibres include less soiling more suppleness, better dimension..

Absorbent characteristics of nonwovens containing cellulosic fibers

Nonwoven fabrics containing high micronaire cotton, low micronaire cotton, regular rayon and modified rayon fibers were studied for their absorbent behavior. The webs containing each of these fibers as well as their blends were produced by a carding process and needled. Measurements of absorbency were carried out with water and saline on ..

Properties of Thermally Bonded Cotton/Polypropylene Nonwovens.

Researchers compared thermally bonded nonwoven blends of cotton and polypropylene nonwoven fabrics, which were prepared by thermal bonding with a calender, with 100 percent polypropylene nonwoven fabrics. They subjected fabrics produced from each lot to a series of bonding temperatures, while processing pressure and speed remained constan..
