Polyester and viscose core-spun yarns are generally made of synthetic fiber filaments with good elasticity as the core filaments, and are twisted with short fibers such as cotton, wool, and viscose fibers. The polyester viscose core-spun yarn has the excellent properties of both the filament core yarn and the outer staple fiber. The more common core-spun yarn is polyester-cotton core-spun yarn, which uses polyester filament as the core yarn and wraps cotton fiber. There is also spandex core-spun yarn, which is made of spandex filament as the core yarn and outsourced from other fibers. Knitted or jeans material made of this core spun yarn stretches freely when worn.

Polyester viscose color spinning is a yarn with unique color mixing effect, which is made by fully mixing two or more fibers of different colors. Characteristics of polyester and viscose colored yarns Different colors of fibers adopt a variety of mixed spinning methods, showing natural and fashionable colors, and the woven fabrics have a hazy three-dimensional effect; the spun yarns can be used directly without dyeing treatment. Knitted or woven fabrics; use without pollution; color difference can be greatly controlled. The use of color spinning is suitable for knitting, sweater, weaving and other fields, and is the preferred yarn for medium and high-end fabrics.

Polyester viscose AB yarn is a composite yarn made by siro spinning technique. (Siro spinning is fed by two sliver with a certain distance into the spun yarn drafting area, which are respectively drafted and bonded to form yarn. Simply put, two rovings are spun into a spun yarn, and such a yarn has strands. The nature of the thread, less hairiness, was mostly used in wool spinning, and now there are many cotton spinning.) Structural characteristics of AB yarn: the co-directional synchronous bonding of siro spinning makes the yarn have a special structure, and the fibers on the surface of siro spinning are arranged Neat, tight yarn structure, less hairiness, good pilling resistance. Compared with stranded fabrics, siro fabrics are softer and smoother to the touch. Siro spinning can be used in woven and knitted fabrics, and can also be used in high-count and high-density fabrics instead of strands.
