Characterizing Fiber Orientation in Heavy Weight Nonwovens.

Researchers compared the efficiency of such image analysis methods as chord tracking, Fourier transform infrared spectroscopy, flow field analysis, and optical Fourier transform analyisis for characterizing fiber orientation in nonwoven fabrics weighing up to 500 grams per square meter. The image analysis system consisted of various digit..

Defect Detection and Formation Characterization in Nonwoven Webs.

Wintriss Engineering Corporation's fourth generation Optical Web Inspection system employs sensor-like video imaging devices and specialized image processing hard- ware and software to detect surface defects on nonwoven fabrics. The sensor consists of a one dimensional array of 1,000-10,000 light sensitive pixels. Combining the images gen..

Trim removal methods

Several solutions have been found to the problem of how to remove the unwanted cutout parts (trim) from a web. If the trim is a continuous piece (ladder trim) it may be wound on a core shaft, drawn off by a vacuum, or chopped up and blown off. When the trim is formed as loose pieces, other solutions are possible but the problem also arise..

Development of innovative cotton-surfaced nonwoven laminated

Cotton-based nonwovens have been developed at Textiles and Nonwovens Development Center (TANDEC), The University of Tennessee, with the cotton fibers on the surface or in the core layer laminated with meltblown (MB) and/or spunbonded (SB) webs. Both Cotton-Surfaced Nonwovens (CSN) and Cotton-Core Nonwovens (CCN) have excellent soft hand, ..

The market in China for nonwoven fibers and fabrics in disposable applications

The primary applications for nonwovens in China are feminine hygiene, baby care and adult incontinence products. A number of textile fibers can be used for disposable nonwovens applications - polypropylene, rayon and bicomponent fibers. Various types of nonwovens are produced in China - thermal bonded, air through bonded, air laid, spunla..

Applications of multicomponent materials for improvements in ballistic protection

The military and police markets are the principal sectors in the ballistic protection Held and greater potential noted in the civilian market with increasing violence in society. Military and police applications are described and end use requirements listed. Threat level definitions and also military and civilian definitions are identifie..

AirWeb: The best of cards and air-lay

The web weights of nonwovens can be determined using a coefficient factor, ‘K’, which multiplies the square root of the fibre fineness in denier. The ‘K’ factor has different values according to the technical composition of the cards and the nature of the web being created. Three processes for producing a product weighing 64g/m2 are b..

U. Engineering: New developments for nonwoven machinery

The latest devices from U. Engineering, Osaka, Japan, which will be exhibited at CMM International 2003 (Chicago-April 2003) and ITMA 2003 (Birmingham, UK-October 2003), are reviewed. The two principal machines will be a web-guiding and wrinkle-removing device, the Caroliner, to be used with converting machinery, and high-speed wrinkle re..

Nonwovens-the merits of their versatility

Nonwovens are here defined as fabric-like materials made of fibres that are not spun but merely joined together in a number of ways. The technology is seen as new, innovative and efficient and this view is supported by a graph that shows production growth of these materials rising from less than 300,000 tones in 1985 to more than 1 millio..
