www.pipaus.com 15 CUT RESISTANT GLOVES Cut resistant gloves can be produced by traditional cut and sewn methods or with newer seamless knit synthetic liner technologies. They feature high performance yarns and fibres to enhance cut and abrasion resistance. It is worthy to note, that the 2nd numeral shown under the AS/NZS 2161 or EN388 mechanical standard logo (a small axe icon) represents the actual cut performance. Both the European and the Australian Standards (AS/NZS 2161.3:2005) are identical in testing methods for glove material cut resistance. Results are calculated by the number of cycles required from a blade, at a constant speed and pressure to cut through the material being tested. The table in our Australian / European Performance Standards, the EN388 ‘Mechanical Tests’ table, shows the various cut ratings (Index) given to each level of tested performance. For a material to attain the next rating in the 5 levels of cut resistance performance, it will need to withstand a doubling of each respective cut cycle. To put this into perspective a cut 3 rating has a required index score of 5, however a cut 5 rating has a minimum required index score of 20, this equates to a threefold increase in cut resistance performance. New generation ultra-fine cut resistant liners now give the wearer assured protection with greatly enhanced user comfort and fine work dexterity not available from tradition cut and sewn materials or previous early technology knitted and coated gloves. The liner provides the cut resistance factor while any coating applied is to enhance the grip and abrasion performance. Kevlar is a knitted or woven cut resistant material with the added advantage of excellent heat resistance. For this reason Kevlar is used rather than HPPE synthetic weave liners where hot objects are handled. Having said this, there are other important factors to take into account when selecting the correct glove for each task. For example; actual physical stresses (fatigue) of wearing a thicker cut resistant fibre or knit liner; loss of intricate sensitivity when handling light to medium / smaller objects; risk analysis for adequacy of protection required and appropriate compliance (wearer acceptance). FEATURES AND BENEFITS • Knit pattern provides all the same benefits of string knits (i.e. breathability, dexterity, etc.). • DuPont claims Kevlar® is pound-for-pound three times stronger than steel fibre of similar size. • HPPE (Dyneema) sometimes blended with glass fibre liners have higher performance and is pound-for-pound ten times stronger than steel, more durable than polyester and a strength that is 40% greater than Aramid fibre. • Kevlar® gloves and sleeves provide good heat protection up to 180 degrees Celsius in short duration contact periods. • Gloves can be laundered for hygiene and to extend glove life cycle and reduce issue costs. • Styles are available with Latex, PU or Nitrile coatings for improved grip and abrasion resistance. COMMON APPLICATIONS • Cut resistant – Food processing, glass handling, automotive manufacturing, metal work, any application where there is a high risk of cuts and lacerations. • Coated Cut Resistant gloves can be used in higher abrasion applications or for improved puncture resistance than plain knitted gloves will offer.
