Abstract

Çalışma yerlerinde sürekli iş kazalarına maruz kalan ellerimizi korumanın en etkili yolu koruyucu eldiven kullanmaktır. Günümüzde eldivenler, hafif ve ince olmalarıyla el maharetini geliştiren ve yaralanmalardan koruyan yüksek performanslı ipliklerle üretilmektedir. Bu çalışmada para-aramid, meta-aramid ve %95/5 meta-aramid/para-aramid karışımıyla üretilmiş iplikler kullanılarak 13G eldiven makinasında eldivenler üretilmiştir. Kesme, delinme, yırtılma ve aşınma dayanımı gibi mekanik riskler EN 388 standardına uygun olarak ölçülmüştür. Ayrıca eldivenlerin mahareti ve yanma davranışları sırasıyla EN420 ve EN ISO 15025 standartlarına göre incelenmiştir. Test sonuçlarına göre para-aramid eldivenler en yüksek koruyucu performansı göstermiştir. Para-aramid liflerinin %5 olarak meta-aramid lifleriyle harmanlanması aleve maruz bırakıldığında kumaştaki büzülmeyi azaltarak kumaş kırılması ve açılmalarını önlemiştir. Bunun yanı sıra kesme, delinme ve yırtılma dayanımı değerlerinde iyileşme gözlenmiştir. Üretilen tüm eldivenler maharet testinde en yüksek seviyeyi yakalamıştır.

INVESTIGATION OF DEXTERITY, MECHANICAL PROPERTIES, AND BURNING BEHAVIOR OF PROTECTIVE GLOVES PRODUCED WITH HIGH PERFORMANCE YARNS

Abstract

Using protective gloves is the most efficient way to reduce accidents at workplace because hands are often exposed to injuries. To reduce weight and thickness and to improve the dexterity and protection from injuries, gloves are now being made from high performance yarns. In this study para-aramid, meta-aramid, and 95/5% meta-aramid/para-aramid yarns were used to manufacture protective gloves on a 13 Gauge glove knitting machine. Dexterity test was carried out as proposed in EN 420 standard and mechanical risks such as cut, puncture, tear and abrasion were determined according to EN 388. The burning behavior of the gloves was measured in accordance with EN ISO 15025. The results revealed that para-aramid gloves are offering the highest protective performance. The dexterity of all the gloves performed the highest level. It was observed that blending of 5% para-aramid fibers with meta-aramid fibers reduce shrinkage of the fabric and prevents the fabric break-opening during flame exposure as well as improving the cut, tear and puncture resistance of the gloves.
