Glass yarn (Glass yarn with Water Blocking effect) are primarily used as peripheral strength elements in fibre optic cables. This flexible and flat glass yarn is composed from premium quality glass filaments and PU-polymeric resins to enhance the properties and increase its abrasion resistance to heavy duty processes.
Textured yarn is a fiberglass thread or yarn treated with under pressure air stream that pushes air between fibers of the thread and makes it bulky.Textured yarn is made bulky with the help of air under pressure. The product’s structure obtained in the process of texturing makes it possible to give the materials processed further the required additional characteristics: to improve the thermal and acoustic insulation and better binding in further soaking.
We offer a wide range of textured glass fibre yarn: from 70 tex to 4,500 tex with various texturing effects and the diameter of the filament 6, 9 or 11 μm. Special textured structure allows to use yarns for decorative solutions such as wallpapers and decorative cloths, meanwhile fitting high technical requirements for application in thermal insulation materials such as smoke and fire curtains, power production construction as well as aviation, space, and chemical industries.

Application :
Glass Yarn Armoured Fiber Optic Cable Series are meant for duct applications. Dielectric strength member – Glass Yarn, gives protection to the cable against rodent attacks. Because of their dielectric nature cables can be laid along with high voltage lines inside ducts.
