Processing trials with lyocell fibers using the stitchbonding technique

First processing trials with lyocell fibers for the production of nonwovens using specific stitch-bonding techniques show that the fibers developed primarily for use in women's outerwearin the lower and medium fabric weight range are also of interest for industrial textiles and in the medical sector, eg for incontinence and antidecubitus ..

Toyobo establishes a polyester recycling company

Toyobo Ecotech Co., Ltd, is a new company established by Toyobo Co., Ltd, and Ebara Corp for the recycling of used PET bottles into flakes or pellets. These will then be used to produce recycled polyester fibre. Toyobo will use 30％ of the fibre for Echorclub products and the rest as materials for nonwoven fabrics. Echorclub is polyester ..

Sorbent nonwovens for waste water filtration

The use of specially-developed sorbents for industrial wastewater removal is discussed. Composite filters made from melt-blown polypropylene nonwovens incorporating different sorbents have been shwon to be effective. Their manufacture and capabilitites are outlined.

Characterization of melt-blown filters made of polypropylene and polypropylene-antimicrobial blends

Melt-blown filter media containing antimicrobial compounds were evaluated for mechanical properties, filtration efficiency, and ability to prevent bacterial growth on the filter. The filters were challenged with gram-negative and gram-positive bactria gro

A support surface used in needling a fibrous web

The support surface claimed consists of two surface sections following one another in the direction of motion of the web, with raised formations inclined in different directions with regard to the needling direction. Two further inclined surfaces form asymmetrical raised ridges which extend in the direction of motion of the web. The diffe..

Measuring fiber orientation in nonwovens IV: Flow field analysis

This paper addresses the development of the image analysis technique of flow field analysis to evaluate local orientation in a finique of flow field analysis to evaluate local orientation in a fibrous assembly. The algorithms are evaluated using simulated images. The results are compared with those from the tracking and Fourier methods pr..

New glass-fiber geometry - a study of nonwovens processability

A recently developed bicomponent glass fiber (Miraflex) shows promise as an alternative to synthetic fibers in nonwovens applications. The unique three-dimensional structure of this inorganic fiber simulates the crimp in polymeric fibers. This paper presents data from studies of three major textile processes (carding, needling, and air la..

Processing Trials with Lyocell Fibres Using the Stitch-Bonding Technique.

Researchers tested different denier and staple length lyocell fibers, alone and in blends, to determine lyocell processing behaviors in five stitch bonding processes. The stitch bonding processes used were Malivlies, Maliwatt, Kunit, Multiknit, and KSB. T

Needing of Cotton Felts.

The mechanical interlacing of fibers by felting needles is used to manufacture natural fiber nonwoven fabrics. Cotton fibers, transported to a feeding station, are formed into the fiber web. A carding system constructs the mechanical fiber web. A carding

Recycling of nonwovens waste

Wastes from the production and making up of nonwoven products provide a valuable reclaimable feedstock, especially where resources are scarce or environmental legislation imposes restrictions. Various recycling methods are reviewed, with indications of their advantages and disadvantages. The outlook for advanced nonwoven recycling technol..
