Anisotroopic characteristics of liquid absorption in nonwoven structures

The anisotropic characteristics of liquid absorption in nonwoven structures, used in medical textiles and personal hygiene products, can markedly influence their performance in use. The anisotropy of liquid absorption is believed to be influenced by the fibre orientation distribution in the fabric plane. A theoretical analysis of planar f..

Influence of production method on the properties of flax/polypropylene nonwovens(German)

Needle-felt nonwovens made of natural and thermoplastic fibers are ideally suited as semi-finished products for manufacturing natural fiber reinforced composites. The process parameters during the production of the nonwovens like area-mass, needle-density or penetration depth have strong influence on the properties of both nonwoven and re..

Performance of nonwoven cellulosic composites for automotive applications

Finding methods to provide a quiet passenger compartment in a car are highly sought after by automobile manufacturers. The ability to reduce nois inside the vehicle enhances the perceived value of the vehicle to the consumer, and so, a competitive advantage to the manufacturer. Several methods to reduce noise and its sources are employed,..

Nonwoven removes stains

A fibrous material intended to remove plaque and other stains from teeth has been invented by Lion. The material is composed of polypropylene, ethylene vinyl alcohol and rayon and eliminates 90% of material adhering to the protein cover of teeth.

Microfibres: a new requirement relating to spunlace technology -f rom polymer to the finished product (German)

Various types of fibres are examined, eg fibres with a sheath/core structure, fibres with a side-by-side structure and microfibres. The spinning of bicomponent fibres and microdenier split fibres is discussed. The AquaJet technique for the splitting of microfibres by water jets in the production of spunlace fabrics is described. These are..

Understanding structures and actions of nonwoven fabrics through microscopical examinations

Structures of nonwovens are different from those of traditional textile materials. Nonwovens, using a wide variety of fibers are finding an increasing market not only in short-term use diposable fabrics, but also as upholstery and carpet linings and pads. Because of this wide range of use, nonwovens are produced in a great range of patter..

Nonwoven processes and products applicable to cotton and other cellulosic fibers

Nonwoven fabrics have quietly revolutionized consumer, medical, and industrial marketplaces throughout the world. They have been the ingredient through which many traditional products have been made better and the means by which many new products have been made possible. The intent of the following presentation is to provide a general ove..

News from the nonwoven sector at Itma (Dutch) (Nieuws uit de non-wovensector op de ITMA)

Innovations presented in the nonwoven sector at the recent Itma are summarized. The constructors had aimed for qualitative improvements, increased flexibility, production speed and ease of maintenance. Equipment highlighted included the ProDyn system by Asselin for producing smooth webs, the Interspun water-jet nonwoven machine by Fleissn..

Cooperative partnerships in nonwovens machine manufacturing (German)

Evidence of co-operative partnerships at ITMA '99 in Paris is discussed. Joint presentation of machines by Trutzscher (fibre preparation), Spinnbau (carding machines), Autefa (crosslappers), and Dilo (needle looms) is examined.

Nonwovens are leaving 'woven fabrics behind' (German)

Progress achieved by the company GKD _ Gebruder Kufferath, a specialist in the manufacture of metal and synthetic fibre fabrics for process lines used in nonwoven fabric manufacture, is discussed in an interview.
