Flax nonwovens for outerwear (German)

The use of stitch-bonded linen fabrics in suits and other forms of outerwear is investigated. The fabrics have good air permeability and sorption properties. Lightweight fabrics are suitable for summer and leisure garments. Heavier fabrics are useful in cooler weather. Their thermal properties are enhanced by raising. The fabrics are prod..

Processing trials with lyocell fibres using the stitch-bonding technique (German)

It is shown that the processing of 1.3/1.7 dtex 40/60 mm lyocell regenerated cellulose fibres by the Malivlies and Maliwatt processes and 3.3 dtex 60 mm fibres for the production of 3D nonwovens by the Kunit, Multiknit and KSB processes have been successful. Using different fibre layers in the fabric constructions, results are obtained wh..

On the pull-out behaviour of single fibre from powder bonded nonwovens (Chinese)

The pull-out behaviour of a single fibre from powder bonded nonwovens was studied in this paper. The distribution of pull-out force and fibre number frequencies meets Gumma distribution. The relationship between mean pull-out force and content of powder is similar to an S curve. The contribution ratios of strength of fibre in nonwovens we..

Bicomponent fibre reduces dust formation in airlaid nonwovens

Danaklon of Varde, Denmark, has introduced a bicomponent for use in the production of air laid nonwovens. The company claims that the fibre reduces the problem of dust formation commonly encountered during production to as little as one fifth of that produced when standard bicomponent fibres are used. It also claims that the bond between ..

Nonwovens application of lyocell fibre

The combination of strength, absorbency, fibrillation and purity make lyocell ideal for a wide range of nonwovens applications. It is made by the best available technology to minimise environmental impact, it has a higher average molecular weight orientation and crystallinity than viscose rayon resulting in a tendency to fibrillate under ..

Technical nonwovens from jute and jute blends

Since 1989 the BTTG has been collaborating with the International Jute Organisation and Common Fund for Commodities, in major projects on the development of nonwovens from jute and jute blends for diversified applications with the objective of increasing

Determining fiber orientation distribution in nonwoven with Hough transform techniques

This research explores the application of an image transform technique, the Hough transform (HT), to measuring fiber orientation distribution in nonwoven fabrics. In this paper, various forms of the HT for straight lines and the implementing algorithms ar

Technical development and applications for nonwoven in geotextiles

There are a variety of different types of geotextiles on the market today including nonwoven needlepunched staple fibers, spunbonded nonwovens with thermal or mechanical bonding, woven slit film fabrics, fabrics woven from yarns, woven monofilament fabric

Energy consumption for hydroentanglement with Fleissner-Aquajet spunlace systems (German) (Energieverbrauch beim Wasserstrahlvemadeln mit dem Fleissner-Aquajet Spunlace System)

This article shows the energy consumed by a Fleissner Aquajet Spunlace system as a mathematical calculation. It also shows that, with the higher stability achieved with the Fleissner spunlace process considerable savings of fibers are possible. The total

Low formaldehyde and formaldehyde free product advances

Nonwovens are being used for a large number of applications and are manufactured for disposable, durable and industrial purposes. Although the use of non-chemical methods to join fibers has recently undergone considerable growth for all such applications,
