Characterizing Absorption in Non-Wovens.

M/K Systems used the MK GATS instrument based on a Johnson & Johnson patent licensed to the company to characterize absorption in cotton or other nonwoven fabrics. The original unit designed in the 1970s sampled products that were characterized by rapid absorption, such as thin tissues. The company redesigned the unit in 1998 for use on t..

Superior Nonwovens Made from Naturally Colored Cottons.

Naturally colored brown and green cotton fibers can be used in the manufacture of needle punched nonwoven fabric blankets despite their short length and low strength with the addition of low melt polymers. A study evaluated blankets manufactured under different heat treatment conditions for such fiber and fabric properties as weight, thic..

Role of Fiber Finish in the Conversion of Fiber to Nonwovens -- Part 1: Need for an Unconventional Method to Evaluate Finish Performance as a Mechanical Process Aid.

An overview of finish treatment requirements for processing fibers into nonwoven fabrics addresses fiber friction, methods for evaluating fiber friction and static charge generation, finish treatments required for carding and needle punching processes, and the ineffectiveness of conventional methods for evaluating finish performance. Lubr..

Biodegradable Nonwovens from Cotton-Based Compositions

Researchers constructed and evaluated nonwoven fabrics containing cotton, focusing on those with cellulose acetate as binder fibers. Modifications to the fibers or processing conditions optimized performance properties. Combinations of cotton and biodegradable thermoplastic fibers resulted in good quality nonwoven fabrics with advantages ..

Ramie/Cotton Blended Nonwoven for Industrial Applications.

An investigation into the processability of ramie fiber in nonwoven fabric manufacture and how ramie improves the properties of cotton and cotton blend nonwoven fabrics prepared and tested nonwovens consisting of simple folded cotton or ramie, double folded cotton or ramie, and simple or double folded 50/50 ramie/cotton for compression, b..

Cotton Core Nonwovens.

Cotton core nonwoven composites are thermally bonded laminates featuring inner fabrics of bleached cotton staple fibers and outer layers of melt blown and/or spun bonded polypropylene fabrics that serve as binder fibers during thermal bonding. The outer layers transport liquid from the surface to the absorbent cotton core. Experiments cha..

Natural Fibers in Nonwoven Processes.

Such natural fibers as virgin and secondary wood pulp, unbleached and bleached cotton, flax, kenaf, and hemp have increasing applications in nonwoven fabrics. Advantages include performance, added value, disposability, and sustainability of raw materials. The high level of production flexibility in nonwoven fabric processes permits the us..

Technology for Stretchable Nonwovens

An overview of technologies for imparting stretch properties to basic nonwoven fabrics compares current techniques for creating popular stretch fabrics with TANDEC's patented web forming system and describes the behavior, elasticity, aesthetic properties, stretch consolidation, and lamination properties of these nonwoven fabrics. In the T..

Electrospinning Nonwovens for Cotton Fabric Coatings

Electrospinning fine polymer nanofibers onto a microporous membrane involves inductively charging a solution of high molecular weight polymers to approximately 10,000 volts, emitting fine jets of charged fiber from the solution surface, and collecting the fiber onto a grounded or oppositely charged substrate, such as a fabric covered elec..

Nonwovens in Filtration.

The filtration industry, one of the fastest growing markets for nonwoven fabrics, is highly segmented by application. Competitive manufacturers must offer a mix of commodity items and niche products. Nonwoven fabrics initially captured market share from woven fabric and paper filtration products, but nonwoven fabric manufacturers are now ..
