Lyocell Staple Fibre in Industrial Applications(Part 2)

Nonwoven lyocell fabrics have twice the dry strength, almost three times the wet strength, higher wet cohesion and wet resilience, stronger thermal bonding with manmade fibers, stronger bonding with latex, less shrinkage, better dimensional stability, and higher absorbency rates and capacities than nonwoven viscose fabrics. Fibrillating l..

Nonwovens Technology.

Important acquisitions and alliances in the nonwoven fabric machinery industry include Rieter's acquisition of ICBT Perfojet, Autefa and Dilo's acquisition of Spinnbau, and Fleissner and Hills Incorporated's joint venture to manufacture microdenier spun laced fabrics using Fleissner's AquaJet spunlacing machine and Hills' bicomponent fibe..

IDEA 2001: Center Stage for Nonwovens.

IDEA, scheduled for March 27-29, 2001 at the Miami Beach Convention Center, is one of three alternating international nonwovens industry events. The upcoming IDEA will feature over 300 exhibitors displaying the most recent manufacturing technologies, fibers, and fabrics. The program will include presentations on home furnishings, filtrati..

Cotton-Blend Nonwoven Fabrics for Medical Use.

Nonwoven cotton fabrics offer superior comfort, absorbency, and wet strength properties for such applications as wound dressings, orthopedic bandages, and surgical gowns and drapes. Research determined optimal blends of cotton and other fabrics for nonwoven fabrics for medical applications. Bleaching and scouring increased the absorbency ..

Properties and Characterization of PBT, PET, Bicomponent PP/PBT and PP/PET Melt Blown Microfiber Nonwovens after Heat-Treatment.

A series of tests established the heat resistance of nonwoven fabrics manufactured from bicomponent polypropylene/polyethylene terephthalate (PP/PET) and polypropylene/polybutylene terephthalate (PP/PBT) microfibers on a 24-inch Reicofil bicomponent melt blown line with a side-by-side configuration that imparted higher crimp, lower averag..

Theoretical and Experimental Determination of Nonwoven Web Properties.

Researchers derived two equations for calculating the pore size and fluid permeability of polypropylene nonwoven fabrics. Although experimental data agreed with theoretical data for melt blown fabrics, discrepancies occurred in needle punched fabrics. The FE of a composite filter media was accurately predicted from the FE of each constitu..

A study of on-line nonwoven defects inspection system PartⅠ: The inspecting methodology of the system (Chinese)

The nonwoven defects inspections system utilizes high speed linescan camera and digital image processing technique to inspect the defects of nonwoven fabrics. The system can automatically record and recognize the image information of the defects. In this paper, we describe the layout of the on-line nonwoven defects inspection system and e..

Long-life Beijing focus

The China International Nonwovens and Techtextils Exhibition and Conference was held in Beijing in May and focused on long-life nonwovens and industrial textiles. Pagers examined: Chinese output and markets; new Japanese fibres for technical textiles; future possibilities for lyocell; Tandec's facilities and programmes; the use of Tyvek f..

Cotton/polyester nonwoven blend with antibacterial activity

Antibacterial needlepunched cotton/polyester webs of varying fiber content (10/90, 20/80 and 30/70 cotton/polyester) were produced by spraying a dilute aqueous dispersion of an environmentally benign antibacterial agent (magnesium hydroperoxyacetate or MHPA), drying and curing the webs, then needlepunching the webs. The composition of the..

Nonwoven fabrics from blends of Greige cotton and recycled polyester

Greige cotton fibers and recycled polyester waste fibers were used to produce low-cost, nonwoven blanket materials that were comfortable, provided thermal insulation, and maintained an acceptable appearance through short-term laundering. Waste polyester remnants are available through a recently developed commercial process. Greige cotton,..
