We have shown in Part I [1] of this study that medical needle-stick injuries are causing serious health problems to healthcare personnel and other professionals that require the attention of healthcare and textile researchers to develop new protective systems. Responding to such need, a needle force measurement device that is capable of measuring dynamic forces experienced by medical needles during needle penetration through protective articles was developed and described in part I. This paper reports the results of evaluation of protective woven fabrics from high performance fibers and standard and bifid medical needles using the force measurement system. The woven fabrics varied in cover factor, number of layers, and orientation angle. Standard and bifid needles with different gap widths were used to evaluate the resistance of the fabric to needle penetration.
Weavability Limit of Yarns with Thickness Variation in Shuttleless Weaving
Seyam, Abdelfattah M. The Korean Fiber Society 2003 Fibers and polymers Vol.4 No.4
Theoretical weavability limit relationships of fabrics from regular warp yarns and fancy filling yams with thickness variation in shuttleless weaving are reviewed. The relationships correlate maximum warp and filling cover factors, warp and filling yarn characteristics, the distribution of thick and thin places of filling yarn over the fabric surface, and the warp and filling weave factor. The research considers single filling feeder and multiple feeders cases. Additionally, comparisons between the weavability limit of regular yarns and fancy yams in shuttle and shuttleless weaving are given.
Prevention of Warp Breaks in Jacquard Weaving
Seyam Abdelfattah M.,Lee, Jin-Ho,Hodge George,Oxenham William,Grant Edward The Korean Fiber Society 2007 Fibers and polymers Vol.8 No.1
We developed a system to monitor and locate warp breaks in Jacquard weaving using MEMS accelerometers that are mounted on harness cords. Brief description of the system is provided and system use to prevent warp breaks through the analyses of MEMS signals is demonstrated.
Protective System from Medical Needle-sticks. Part I: Background and System Development
Turner, LaDawnya C.,Seyam, Abdelfattah M.,Banks-Lee, Pamela The Korean Fiber Society 2003 Fibers and polymers Vol.4 No.2
Previous research on healthcare workers’ protection has concentrated on liquid barrier protection by providing impermeable personal articles such as latex gloves. This property is of high importance but since most blood-borne pathogen transmissions in the healthcare industry are caused by needle-stick injuries, protection from sharp invasive instruments should also be of high concern. And since latex and alike provide no protection against needle-stick injuries, new protective systems need to be developed and evaluated. This part of the study provides a review regarding the current practice of protection and the serious problems that arise from needle-flick injuries. Additionally, the development of new protective system is described. In part II of the study, evaluation of the new system will be provided.
