1000 Denier Water Blocking Yarn
Water blocking yarn has the characteristics of quick water absorption, high expansivity, high tensile strength, no acid-basis, no consistency influence with cables, heat resistance, chemical stability and no corrosively etc. In the production of cables by using water blocking yarn, the materials of water blocking tape, polyester yarn and ointment could be omitted. Besides that, water blocking yarn is convenient in using, simple in techniques, stable in structure, reliable in water blocking, clean in environment, and no greasy pollution, especially, used in waterproof communication cable, dry-type cable, and insulation electronic cable, especially benthic cables.
