Hydroentangled Fabric Performance of Polyester/Unbleached Cotton Blends at Various Levels of Specific Energy Levels.

A study examined the effect of hydroentanglment on the physical properties of polyester/cotton fabrics and the effect of cotton fiber bleaching on absorption capacity. Tensile strength increased as the total specific energy of the water jets increased, re

On-line determination of fiber orientation in a nonwoven web

ABB Industrial Systems Inc. are manufacturing a method and apparatus for the online determination of fibre orientation and anisotropy in a nonwoven web. The measurement is performed by directing three light sources toward a sensing region of the web. The scattered light is detected by sensors which calculate a fibre orientation angle rela..

On-line quality control in needled nonwoven

On-line measurement of specific characteristics of nonwovens in the production process offers the advantage of detecting defects during manufacture. The integration of quality monitoring into process automation in nonwovens production requires a knowledge of the influences of process variables in web forming and consolidation on nonwovens..

Study of the bonding behaviour of fibres and webs (German)

findings on the thermomechanical bonding of fibres in heat bonding are of scientific and practical interest. A bonding rig is described which makes it possible to create bonding points at intersecting fibres and bonding surfaces at model webs as a function of temperature, deformation and contact time. This represents a rapid test method f..

Nonwoven diskette liners

International Paper Co. have created a composite nonwoven fabric that presents a cellulosic fibre face to the recording medium on a computer diskette. The company says that the fabric offers superior wiping and hygroscopic dimensional stability combined with very los debris characteristics. This article describes the construction of the d..

Biodegradable Nonwovens Based on Renewable Resources? One Answer: Deposa.

Most nonwoven fabrics are manufactured using environmentally stable polymers that prevent quick degradation. DEPOSA nonwoven fabrics are manufactured using polylactic acids (PLA's) that are 100 percent degradable and compostable but remain resistant to wa

Dry Laid Web Formation.

Manufacturers of dry-laid nonwoven fabrics normally use fibers of 1-4 deniers. Lower denier fibers yield softer more uniform fabrics but require slower production rates. Higher denier nonwoven fabrics have a stiffer hand and less uniformity, but have high

A New Evaluation System for Nonwoven Fabrics Using Image Analysis Technique: Coverstocks, Filters, and interlinings

A study examined the use of image analysis to evaluate polyester, polyethylene, polypropylene, and rayon nonwoven fabrics for coverstock, filters, and interlinings. Bonding systems for the sample nonwoven fabrics included chemical, melt blown, spun bonded, and thermal bonded systems. Researchers measured air permeability, filtration, and ..

A Comparison of the Degradation of Cotton-Based Nonwovens by Composting and Heat-Moisture Treatments.

Researchers investigating the influence of cotton content on the degradability of nonwoven fabrics compared the physical and morphological properties of three nonwoven fiber webs (Hydroentangled cotton, polyproplene microporous film/hydroentangled cotton, and polypropylene microporous film/spun bonded polypropylene) subjected to one of th..

Stitchbonding Principles ＆ Applications.

Stitch bonding joins fibrous webs by stitching through a multidirectinally arranged yarn network with binding yarns. The process locks the layers of fibers or other flat sheets into a warp knit structure. The Arachne stitch bonding method delivers cross l
