What is spun yarn?
Spun yarn is made by twisting staple fibers together to make a cohesive thread. Spun yarns may contain a single type of fibre, or be a blend of various types. Combining synthetic fibers with natural fibers is very common. The most widely used blends are cotton-polyester and wool-acrylic fibre blends.
What are the characteristics of filament yarns?
Filament yarns are made by gathering together long continuous fibers, with or without inserting twist. Filament yarns produce fabrics that are smooth and slippery to the touch. They are also stronger than staple yarns, which is why before the discovery of synthetic manufactured fibers parachutes were made of silk.

Ring-spinning, which is a system of spinning using a ring and traveler take-up, twists and winds the yarn simultaneously and continuously. Open-end spinning, on the other hand, is a system of spinning where the yarn is twisted by rotating at the hap or break in the flow (the fibers wrap around the yarn v.
Why is spun yarn not frequently used in warp knitting?
Spun yarns are not used frequently in warp knitting. These yarns are composed of short fibers twisted together to form the structure. The yarn is not as strong or uniform as filament yarn and some of the fibers shed from the yarn and form a contaminant on the warp knitting machine.
Why is fiber spun into yarn before making clothes?
The natural properties of the cotton fibre make it easy to spin into a strong thread. … This makes cotton so suitable for spinning into thread. The new world cottons have longer fibres than their old world cousins. This means they can be spun into finer and stronger yarns.
