From Molten to Laminated Products.

Simple modular equipment that complements spunbonding and melt blowing processing lines can produce a large range of multilayer or laminated textile products. The combination of spunbonding or melt blowingn with this laminating process increases the end use potential of these multilayer or laminated products. A discussion of this modular ..

High Productivity, Low Cost Manufacturing of Needle Felts.

The newly developed H-1 needle felting technology from Ernst Fehrer produces stronger and more uniform felts, extends the felt life and improves drainage of papermaking felts, requires fewer passages through the needling system, and can be retrofitted to

Italy Meeting the Demand for Ultra-Thin Products.

Many Italian companies manufacture fabrics and equipment to meet the demand for ultrathin nonwoven fabric products. Fabriano Soft's range of nonwoven fabrics includes personal care spun bonded fabrics weighing 23 grams per square meter and a range of white themmal bonded fabrics weighing 18, 20, and 22 grams per square meter. The fabrics ..

INDA-TEC 96: Book of Papers: International Nonwovens Conference.

A book of papers presented at the INDA-TEC 1996 International Nonwovens Conference addresses such topics as dry-laid web formation, wet form nonwoven fabric production, needle punching, stitch bonding, hydroentanglement, supunlacing, chemical bonding, the

Image analysis techniques to characterize nonwoven web structure

Image analysis hardware and software techniques used to characterize the structure of nonwoven webs are discussed. Hardware is discussed first and emphasis is placed on selecting hardware to accommodate a variety of webs structures. Then, examples of web structrual features measured by image analysis in our laboratory will be given. These..

Processing and physical properties of cellulosic nonwovens from blends of cotton and cellulose acetate

Environmentally friendly (biodegradable or compostable) nonwoven fabrics can be formed from the thermal calendering of a blend of cotton and cellulose acetate fibers. The physical behavior of the resulting fabrics is determined by the properties of the component fibers, the thermal conditions for bonding, and additional pre-treatment cond..

Fatigue behavior of aramid nonwoven fabrics under hot-press conditions. IV: Effect of fiber fineness on mechanical properties

We set out to find the most suitable design for heat-resistant nonwoven fabrics to be used as components of laminated cushion materials. The changes in mechanical properties and durability of a nonwoven fabric subjected to repeated hot-press fatiguing tre

Characterizing nonwoven web structure using image analysis techniques

A discussion of image analysis hardware and software techniques used to characterize the structure of nonwoven webs shows the advantage of modifying electronic images to allow better visualization by humans. Spectral analysis is useful for characterizing web structure globally. The authors examine simple parameters useful for describing w..

Effect of pressure, temperature and time on the bond strength in laminating fabrics from polyester filament yarn with plastic and/or metal films (AIF No. 9414B) (German)

The effect of the title process variables on the bond between woven polyester fabrics from filament yarn and plastic/metal films is examined in this research report. The overall trend is for the bond strength to increase with a reduction in speed and an increase in pressure. There is a first relationship between the separating force and t..

High productivity, low cost manufacturing of needle felts

This article discusses a needle felting process which promises massive increases in productivity and savings in manufacturing costs. It is said the new process produces stronger, more even felts; extends the life and improves the drainage of felts for papermaking; requires fewer passages through the needling system and less energy to prod..
