Viscose yarn

Blended yarn has been used in sportswear for several years. The soft fabric blends made from bamboo yarns are elastic, durable, and easy to dye. Jeans are made with cotton blends, and so are men's, women's, and children's slacks. Blended yarn is commonly used in the production of sweaters, socks, and blankets.

Polyester yarn is made from post-consumer waste such as bottles, fabrics, etc., in the composition of polyester ethylene terephthalate (PET), and because of its superior strength and elasticity it is applicable to a number of geotechnical applications: roadbed reinforcement of road and railway, crack prevention, increase of roadbed strength; reinforcement and stabilization of riverside, embankment and side slope, dyke reinforcement on soft ground for stress evenness, sedimentation adjustment, increase of stability and loading capacity of fundus, and reinforcement of the surface of roads and bridges. Polyester yarns are obtained by melt spinning from a polymeric melt at 265 °C. In polyester yarns, crystalline and amorphous areas exist. They are a thermoplastic material. The chains have a zig-zag structure and are linked to each other by Van-der-Waals connections.

Viscose yarn actually behaves quite a bit like cotton, as it's very absorbent and breathable. This along with its lightweight characteristic and hardiness makes it a great fabric for warm weather wear. Since it's so cheap to produce, it's cheap to the consumer, as well, but it won't be very helpful for people who are concerned with staying warm, because it does not insulate well. People who live in warmer areas will find viscose is their best friend, but people who live where there are harsh winters and mellow summers, or people who are more concerned with the environment, may use this fiber less.
