Cabled yarns

We manufacture cabled (steel wire) yarn from spooled E-glass yarn with thermal resistance of up to 600°C, twisted together with 0.1 mm stainless-steel wire. This yarn has higher mechanical resistance that ensures the required structural performance in end products. Cabled yarn is used to weave fabrics mainly used in the production of high-quality fire barriers.

Cabled yarn is made of a combination of spooled E-glass yarn and stainless-steel wire. During the cabling process, two E-glass yarns are connected with a stainless-steel wire, and the yarn is closely twisted to connect all the threads together. Upon request, the size of the yarn and wire can be customised.

Application: fire barriers, manufacture of smoke and fire curtains.
Technical specifications:

  • twist direction: S or Z,
  • twist: up to 355,
  • wire: tempered stainless-steel, 0.1 mm diameter,
  • ignition loss: 0.6-1.0%.

Greaser used:

  • 333P: silane resin-based sizing.

Parameters: cabled yarn is spun on cylindrical cardboard shells, bobbin weight: 6.3 kg.

HR-glass (High-Resist glass) is alkali-free aluminosilicate glass that does not contain boron oxide and fluorine. This glass type could fully substitute E-glass in various aspects. The most important feature of this type of glass is its heat resistance of up to 800°C.

Advantages of HR glass fibre compared to E-glass:

  • higher chemical resistance, particularly in alkaline and water environments;
  • higher heat resistance;
  • environmentally friendlier glass melting process - does not create dust emissions containing boron oxide.
