Method of making a stabilized extensible nonwoven web

The present invention provides a stable nonwoven web having enhanced extensibility and a method for making the same. A able nonwoven web is fed in a first direction. The neckable nonwoven web is subjected to incremental stretching in a direction perpendicular to the first direction. A tensioning force is applied to the neckable nonwoven w..

Getting right to the point

This article reports on a recent seminar held at machine builder William Tatham's in Rochdale, UK, which focussed on the finer details of needlepunching processes. The reports describes the different groups of felting needles and their applications, and discusses trends in needling techniques.

Stitchbonded airbags

Modern car airbags are normally made from high tenacity materials such as rip-stop nylon. However, a new development has been suggested by the Minnesota Mining and Manufacturing Co., St. Paul, using a low permeability stitchbonded fabric. This new material has first and second surfaces comprising a thermoplastic base web and a two-bar war..

Calender technologies in the nonwoven industry (German) (Kalender-technologien in der vliesstoff-industrie)

The calender is a machine with rollers. Two or more rollers turn against each other and process the substrate passing between them. The purpose of the calender is to alter the surface, compress the fabric, improve the hand, thermobond nonwovens, groove felts, laminate composites etc. The floating roller (Sroller) developed by the German f..

Product construction by various calender designs and roller systems (German) (Produktgestaltung durch unterschiediche kalanderkonzepte und walzensysteme)

The production of nonwovens using calenders is described. Nonwoven calenders generally have 2 or 3 rollers. The Nipco-L calender is the first genuine 3 roller calender with two nips working in parallel. The most important differences between calenders for nonwovens are the rollers. Heating and cooling mechanisms are in second place. The m..

Inspection of nonwovens (German) (Inspektion von Vliesstoffen)

During the manufacture of nonwovens a number of defects can occur which are not acceptable in subsequent processing or later use. For this reason the inspection of nonwoven materials during all manufacturing and subsequent processes is very improtant. The article presents inspection equipment produced by the German firm Erhardt + Leimer G..
