The nonwoven flopy disk linear market in Japan

The liners for floppy discs, which are constructed from nonwoven sheets, protect the disc from flaws caused by dust and contributes to the stable rotation of the disc. The Japanese market has risen from 1240 million discs in 1990 to 2514 million in 1995 with the volume of nonwoven fabric used increasing from 30.3 million to 41.3 million s..

Testing the limit of sportion of oily substances by polypropylene nonwovens (Polish)

The results of various tests show that the best results on oil absorbency are obtained with melt-blown polypropylene microfibre fabrics. Polyolefin nonwovens produced by the classical method also give good results.

Complex unit for textile waste and the production of nonwovens (Russian)

A machine for tearing knitted fabric waste and producing air-laid nonwoven fabrics for use as waddings in furniture manufacture is described. The torn-up waste contains 88％ recovered fibres.

Ultrasonic technology comes of age

This paper discusses the use of ultrasonic bonding, as a high tech method of materials processing, in the nonwovens industry. It traces the technological advances of ultrasonic techniques; high-lighting nonwovens' small but growing representation in various market segments, and predicted various opportunities for ultrasonically processed ..

An approach to the theory of compression of nonwoven fabrics

A theoretical analysis of the compressional behaviour of nonwoven fabrics has been proposed based on bending of fibre elements. A fibre segment, which is assumed to be bonded at two neighbouring contact points, has been chosen as the unit bending element. An interactive algorithm, in which the system geometry is updated on successive incr..

Influence of the constructing conditions of quilted fabrics on the fabric properties. I (Japanese)

The influence of the constructing conditions of quailted fabrics on the fabric properties was discussed. The results were as follows: the thermal insulation value of quilted fabrics increased with the number of layers of nonwoven fabrics and the spacing b

Polypropylene melt-blown nonwovens as absorbents of oil-type substances

This article presents the lubricating oil absorbent properties of selected melt-blown nonwoven products. These products are developed and manufactured at the Polish Textile Institute, Lodz. Using the mechanical squeezing and centrifuging methods, it was confirmed that the absorbent materials are suitable for repeated use in the collecting..

Self-crosslinking binder

Airflex Dev emulsion is a self-crosslinking binder for nonwovens and other textiles. It is based on vinyl acetate-ethylene and is suitable for the manufacture of products where high wet and dry strengths, a soft handle, excellent absorption, ultra-low formaldehyde levels, low residual vinyl acetate monomer levels and low odour are demande..

Ingredients for nonwovens

This review article on the production of nonwoven fabrics considers the equipment and processes available to make new and different products. Following an outline of the basic methods of producing nonwovens, the additional production methods available, including the use of binders, coating and saturating, laminating, additives and off-lin..

Recylcing of Nonwovens Wastes

Nonwoven fabrics manufacturing waste can be converted into reclaimed feedstock in either pourable agglomerate or regranulate form via a batch agglomerating plant, friction disc condensation, or screw extrusion. Batch agglomeration plants and friction disc
