Europe's largest plant for high-bulk thermobonded nonwovens now on stream

The Geman nonwovens manufacturer Christian H. Sandler produces high-bulk thermobonded nonwovens for upholstered funiture, leisure furniture and speciality technical nonwovens. Their new plant is accredited to ISO 9001 and employs state-of-the-art automation technologies and a complex computer control system. In the thermofusion process di..

Wettability of nonwoven fabrics. II. Effect of cationic surface treatment

The effect of two cationic surfactants on the wettability of three fluorochemically- and corona-treated nonwoven fabrics is studied. The water contact angle, demand wettability and static absorption are measured. It is concluded that surfactant build-up on the surface of the fibres reduces the water repellency of the fabrics.

Wettability of nonwoven fabrics. I. Effect of fluorochemical finishes on water repellency

The effect of fluorochemical finishes on the wettability of three nonwoven fabrics for protective garments is examined. Capillary flow rates (CFR) are estimated from the results of an analysis of the water contact angle in combination with the fabric pore radius. Expected CFRs are then compared with experimental results obtained from dema..

Staple Fiber Usage in Japan.

Polyethylene terephthalate (PET), polyolefin, and rayon are the primary fibers used in the production of nonwovens in Japan, constituting 85 percent of the total staple fibers consumed. Japanese consumption of staple fibers achieved 140,000 tons in 1995. Primary nonwoven uses of PET include needled automotive nonwoven fabrics. The recycli..

Characterizing Nonwoven Web Structure Using Image Analysis Techniques.

An important application of image analysis techniques by the nonwoven fabric industry is the characterization of web structures. Histogram modification of the acquired electronic images significantly improves visualization by humans. Spectral analysis in the frequency domain is useful in the global characterization of web structures. Imag..

Index 96: Nonwovens Conference.

An overview of INDEX 1996, the ninth nonwovens conference, lists 1996 prize winners in the disposable, durable products, raw materials, machines, and marketing categories; summarizes key fibers introduced in technical papers; lists the advantages and disa

Image Processing as a Tool to Improve Machine Performance and Process Control.

Researchers used image processing as a tool to determine the trash content in cotton webs. The reproducible results allow the user to distinguish between different knids of trash particles, such as neps, seed coat particles, leaf and wood fragments, and extraneous fibers, and to determine the exact composition of these particles in the co..

Viscose Fibres in Wiping.

Fiber properties play a key role in determining the performance properties of nonwoven fabrics. The high liquid absorption and retention capacity of viscose fibers render them especially suitable for nonwoven wipes in residential, industrial, and medical apllications. Viscose fibers used in surgical wipes are bleached without chlorine and..

UK Bleacher Introduces Super Clean Cotton for Nonwovens.

United Kingdom cotton supplier Edward Hall Limited has introduced a new version of its Luxicot cotton, called Luxicot Ultraclean, a bleached cotton fiber with exceptional cleanliness, purity, and low neq levels for easy processing. The new fiber is design
