Multi Plied Glass Processing Yarn and Cord

Multi-Plied E Glass Processing Yarn and Cord

Multi-plied glass yarn, sometimes referred to as cabled glass yarn, is produced by twisting together two or more plied yarns to create a larger, stronger and more robust yarn construction. This secondary twisting operation results in a highly cohesive yarn containing multiple constituent ends whilst maintaining excellent flexibility and textile processing characteristics.

The multi-plying process increases tensile strength, yarn stability, abrasion resistance and bulk, making these constructions particularly suitable for demanding thermal insulation and industrial textile applications. Compared with assembled yarns, multi-plied yarns provide superior cohesion and a more uniform, round cross-section, improving performance during weaving, braiding and rope manufacture. In particular, Multi-plied E Glass processing yarns are used in heat trace applications or used for further coating to make sewing threads. 

Typical examples include:

• EC9 68/3/2 (6 ends)
• EC9 68/3/3 (9 ends)
• EC9 136/3/2 (6 ends)
• EC9 136/3/3 (9 ends)

For example, a 68/3/3 construction consists of three 68 tex single yarns twisted together to form a plied yarn, with three of those plied yarns then twisted together again to create a final 9-end cabled construction.

Multi-plied glass yarns are widely used in the manufacture of thermal ropes, braided packings, high temperature webbings, electrical insulation tapes, thermal sleeving and industrial sealing products where increased strength, bulk and durability are required.

The combination of high tensile strength, excellent thermal resistance and superior processing performance makes multi-plied glass yarn one of the most commonly specified yarn constructions within the high temperature textiles industry.
