Applications
１．Gloves
Tsunooga® is a high strength polyethylene fiber with excellent cut resistance. Gloves made with Tsunooga® is a soft and nice texture. Also, no solvents are used in the manufacturing of the fiber, so it is better than other HMWPE yarns from a hygienic standpoint.
２．Bedding
-
‘Tsunooga®’ has high specific heat and high thermal conductivity, so it absorbs heat from the skin, thereby diffusing heat. Using the fiber in fabrics gives the fabric a cool touch to the skin.
