Interest of a compound yarn to improve fabric performance

Ferreira M., Bourbigot S., Flambard X., Vermeulen B.

The market for protective clothing is growing in many fields, including flame resistance clothing, cut-resistance gloves and so on. High-performance fibres such as aramides are known to be flameproof and resistant to mechanical impacts, but they are sensitive to UV.The purpose of this study was to produce compound yarns with the advantageous properties of aramides and insensitive against UV radiation. We obtained such yarns by means of a friction process (FEHRER), a non-conventional spinning process. The yarn obtained, denoted as DREF yarn, developed by us is a combination of wool and poly-pphenylenediamine-terephtalamide fibres (Kevlar®29). The compound yarn is composed of a core in Kevlar® yarn, coated by wool fibres. The DREF yarns were then knitted; the articles obtained have interesting properties such as flame retardancy, good-handle, cutting resistance, and are also UV-resistant.
