Influence of nonwoven structure on the burning behaviour of bondings, including fabrics and nonwovens (German)

Investigations were carried out to measure the burning behaviour of nonwoven underlays and composites incorporating Malivlies and Kunit stitch-bonded fabrics in accordance with DIN 75200 (horizontal flame spread method). Quantitative methods for measuring and describing the structural and surface characteristics of the composites were mod..

ITMA 99 survey 21: Nonwovens equipment

Nonwovens is a sector undergoing more rapid technological change than others in the textile industry, as was evident from many innovative machines showcased at ITMA 99. Developments are outlined in spunlace; needle punching; opening, blending and web-formation lines; processing and on-line quality control.

A hybrid market for nonwovens (Spanish) (Un mercado hibrido para los no tejidos)

Many new products are developed by combining existing materials or processes to form a new product which is a hybrid. Nonwoven technology can be considered a hybrid since this technology represents a combination of various basic technologies such as textiles, polymers and paper-making. The article presents examples of recent developments ..

Biodegradable wound dressing improves healing of burns.

A three-layered, biodegradable wound dressing which improves the healing process of third and fourth degree burns has been developed. The new dressing incorporates layers of chitosan and synthetic polymer compounds under a gauze layer, and is lightweight, flexible, odor-free and impermeable to micro-organisms; but permeable to water vapor..

Wound dressing: Chitosan-containing nonwovens for use in wound healing

Disclosed are the benefits and production methods for chitosancontaining wound dressings. As well as a bactericidal effect, the nonwovens support the skins physiological secretion process for wound healing and help to stimulate the body's own healing process. Wet-laid nonwovens have been prepared by blending fibrillaed lyocell and chitosa..

Index '99 - a quality, international show

The theme of this year's nonwavens exhibition and conference held in Geneva in April was wrapping and packaging. More than 450 exhibitors from 35 countries attended. New developments on sow for the first time were on offer from suppliers of raw materials and fibres (Acordis, Lenzig), auxiliaries (Got-tlieb Binder), machines and accessorie..

Absorbing new developments

The recent Insight conference in San Diego focused on the latest advances in airlaying, with the emphasis on the diaper and hygienic disposables markets. Presentations looked at the role of cotton in airlaid nonwovens ; diaper design improvements ; superabsorbents production; chemically bonded nonwovens, and odour control in adult inconti..

Nonwovens report international fibres guide 2000

This sixth edition of the guide lists major suppliers of fibre for the European nonwovens industries. Companies' contact details, brandname products and their characteristics are given, listed alphabetically by company name in tabular form. A section also covers binders, films and adhesives.

Influence of fiber structure on properties of thermally point bonded polypropylene nonwovens

Carded webs with a basis weight of 30 g/㎡ are prepared from Hercules T-196 and Hercules T-101 polypropylene fibers, then thermally point bonded with 'Novonette' rolls at various temperatures and pressures. A subset of samples is studied in relative detail using various methods. In particular, the distribution of bridging fiber strengths ..

Method for producing a nonwoven glass fibre mat comprising bundles of fibres

The method involves adding chopped glass fibres to a water slurry containing sufficient hydrophobic agent to cause the fibres to form bundles. The fibres are then formed into a mat which can be used in reinforcement applications. IPC D21H.
