Twistless roving is further divided into direct twistless roving and plied twistless roving. Direct (Glass fiber yarn) yarn is a continuous fiber drawn directly from glass melt, also known as single-strand roving. Ply yarn is a coarse yarn made up of multiple parallel strands of raw yarn. Simply put, it is a direct synthesis of multiple strands of yarn.
Let me teach you a little trick, how to quickly distinguish between direct of yarn and plied yarn? Pull out a yarn and shake it quickly. The yarn that remains in one yarn is the direct yarn, and the yarn that is dispersed into multiple strands is the (glass fibre) ply yarn.
What is direct yarn? The difference between (glass fibre) direct yarn and plied yarn, glass fiber direct yarn or single-strand roving is a continuous fiber directly drawn from a 2000-hole or 4000-hole leaky plate. Mainly used in winding and pultrusion molding processes, suitable for UP, VE and EP. Typical products are: pultruded rods, window frames, ladders, pipes, communication cables, storage tanks, woven square fabrics and chemical-resistant gratings, etc. Ply yarn is actually a thread, which is formed by twisting two or more single yarns together through a twisting process.
